Practical ERP guidance
The CEO's Playbook for Escaping ERP Vendor Lock-In: A Strategic Framework for a Future-Ready Enterprise
As a CEO, you are the ultimate steward of your company's long-term viability. You make strategic bets on markets, products, and people. Yet, one of the most significant and often underestimated risks to your company's future is hiding in plain sight: your Enterprise Resource Planning (ERP) system. Many leaders find themselves in a gilded cage, trapped by a legacy ERP vendor that once promised efficiency but now delivers rigidity, escalating costs, and a frustrating inability to innovate. This isn't a sign of a poor initial decision; it's the natural consequence of a business that has outgrown its technology. The monolithic systems from vendors like SAP or Oracle, once the gold standard, can become a significant drag on agility, making it nearly impossible to adapt to market shifts or launch new initiatives without a king's ransom in consulting fees.
This article is not another theoretical discussion about the dangers of vendor lock-in. It is a pragmatic, actionable playbook designed specifically for CEOs and founders. We will move beyond the fear and uncertainty of being trapped and provide a clear, de-risked framework for planning and executing your escape. The goal is to regain control over your operational and technology destiny, transforming your ERP from a source of constraint into a platform for growth. We will explore how to diagnose the severity of your dependency, architect a phased exit strategy that won't disrupt your business, and build a compelling financial case for the board. The truth is, freedom from ERP vendor lock-in isn't just possible; it's a strategic imperative for any company serious about its future.
Key Takeaways for the CEO
- Vendor lock-in is a business risk, not just a technology problem. It directly impacts your ability to innovate, control costs, and respond to market opportunities. The dependency on a single vendor for critical operations creates significant financial and strategic vulnerabilities.
- A 'rip and replace' strategy is a recipe for failure. The most effective way to escape a legacy ERP is through a phased, modular decoupling strategy. This involves systematically replacing individual functions (like CRM or inventory) over time, minimizing operational disruption and showing incremental ROI.
- Your data is the primary hostage; liberating it is the first step. A successful exit hinges on a robust data migration plan. This requires establishing master data governance and cleansing data before you begin the transition, ensuring business continuity and the integrity of your new system.
- The financial case for escaping lock-in is built on Total Cost of Ownership (TCO) and agility. The true cost of a legacy ERP includes not only high maintenance fees but also exorbitant customization costs, integration challenges, and the opportunity cost of lost business. A modern, modular ERP offers a more predictable and value-driven financial model.
- True freedom lies in a composable, API-first architecture. The end goal is not just to switch vendors but to build a flexible enterprise backbone. A platform like ArionERP, with its modular design and open APIs, allows you to integrate best-of-breed tools and adapt your technology stack as your business evolves, ensuring you never get locked in again.
The Gilded Cage: Why ERP Vendor Lock-In Happens to Smart Companies
No intelligent leadership team willingly signs up for vendor lock-in. The situation develops gradually, often as a result of past success. The ERP system that was a perfect fit for your company five or ten years ago becomes an anchor as your business model evolves. This dependency is not a single event but a slow, creeping process built on a foundation of proprietary technology, contractual obligations, and operational inertia. The initial investment in a Tier-1 ERP is so substantial that it creates a powerful psychological and financial incentive to stick with it, even as the evidence of its limitations mounts. Over time, your teams build processes and workarounds specific to that system, embedding the vendor's DNA deep into your operations.
The common approach to dealing with a failing ERP is to either endure the pain or contemplate a massive, high-risk 'rip and replace' project. This big-bang approach is what most vendors and large system integrators propose, as it represents a significant revenue event for them. However, for the CEO, it represents a massive bet-the-company initiative fraught with peril, including budget overruns, operational disruption, and the potential for outright failure. This binary choice—suffer or explode—is a false dichotomy presented by the very ecosystem that benefits from your dependency. It ignores the strategic, lower-risk alternatives that are available to savvy leaders.
The mechanics of lock-in are multi-faceted, extending far beyond a simple software license. It manifests as technical debt from years of customizations written in proprietary code that cannot be easily transferred. It appears in data models that are intentionally complex and difficult to export, effectively holding your most valuable asset hostage. It is written into long-term contracts with punitive exit clauses and escalating maintenance fees that can consume an ever-larger portion of your IT budget. This combination of technical, operational, and contractual hooks creates a powerful gravitational pull, making the prospect of leaving seem more painful than the cost of staying.
For a CEO, the practical implications are severe and strategic. Your COO is unable to optimize the supply chain because the inventory module is rigid. Your Head of Sales cannot integrate a modern CRM because the ERP's APIs are closed or prohibitively expensive. Your CFO is forced to approve a seven-figure budget for a mandatory upgrade that offers minimal new business value. In essence, your company's strategic roadmap becomes dictated by your ERP vendor's product roadmap and pricing strategy. This loss of agility and control is the true, hidden cost of vendor lock-in, and it is a cost no growing company can afford to pay indefinitely.
Diagnosing Your Dependency: A Framework for Assessing Lock-In Risk
Before you can chart an escape route, you must first understand the precise nature and strength of your cage. A CEO needs a clear, quantifiable assessment of the company's vendor lock-in risk, one that can be communicated to the board and executive team without getting lost in technical jargon. This diagnostic phase is about moving from a general feeling of being 'stuck' to a data-driven understanding of your specific vulnerabilities. It involves a holistic review of your relationship with the vendor, covering everything from the legal print in your contract to the architecture of your custom code. This assessment provides the foundational business case for change, highlighting the tangible risks to business continuity and financial health.
To facilitate this, leaders can use a decision artifact like a Vendor Lock-In Risk Assessment Matrix. This framework allows you to score your current ERP system across several critical dimensions, creating a clear heat map of your biggest risks. The goal is not to achieve a perfect score but to identify where the dependency is most acute and where a phased exit strategy should begin. By breaking down the problem into measurable components, you transform an overwhelming challenge into a series of manageable problems. This structured approach is essential for building consensus and securing the resources needed for a successful migration.
The following Decision Artifact provides a practical model for this assessment. It evaluates four key pillars of vendor dependency: Contractual & Legal, Technical & Architectural, Operational & Process, and Financial & Commercial. Each area contains specific factors that contribute to lock-in, scored on a simple 1-5 scale where 5 represents extreme risk. This tool is designed for the executive team, enabling a strategic conversation about risk and the justification for investing in a more flexible, future-ready platform like the one offered by ArionERP.
For example, a company might score a 5 on 'Customization Portability' because all their unique business logic is written in a proprietary language like SAP's ABAP, making it non-transferable. They might score another 5 on 'Data Egress Fees & Complexity' if their contract allows the vendor to charge exorbitant fees for a full data export. Conversely, they might score a 2 on 'Internal Skill Dependency' if they have a strong internal team that understands the system. The resulting scorecard provides a visual and compelling narrative about the true extent of the company's vulnerability and points directly to the areas that must be addressed first in any exit strategy.
Decision Artifact: Vendor Lock-In Risk Assessment Matrix
| Risk Dimension | Assessment Factor | Description | Risk Score (1-5) | Notes & Implications |
|---|---|---|---|---|
| Contractual & Legal | Ease of Termination | Penalties, notice periods, and contractual barriers to ending the agreement. | High scores mean significant financial or legal hurdles to exit. | |
| Data Ownership & Egress | Clarity on data ownership and the contractual right to extract data in a standard format at a reasonable cost. | Are there punitive data egress fees? | ||
| License & Audit Risk | Risk of vendor audits and 'indirect access' claims that drive unplanned costs and dependency. | High audit risk forces compliance over innovation. | ||
| Technical & Architectural | Customization Portability | Degree to which custom code and business logic are built on open standards vs. proprietary vendor languages. | Proprietary code (e.g., in SAP, Oracle) is a primary lock-in driver. | |
| Integration Openness (APIs) | Availability, cost, and documentation of APIs for connecting to third-party systems. | A lack of open APIs isolates the ERP, forcing reliance on vendor modules. | ||
| Data Model Complexity | The ability to easily extract, understand, and map your data to a new system. | Proprietary and undocumented data schemas make migration a nightmare. | ||
| Deployment Flexibility | Ability to deploy on different infrastructures (On-Prem, Private Cloud, Public Cloud of choice). | Forced bundling with a vendor's cloud is a modern form of lock-in. | ||
| Operational & Process | Internal Skill Dependency | Reliance on highly specialized, certified vendor-specific skills that are expensive and hard to find. | High dependency makes you vulnerable to talent shortages and high salaries. | |
| Process Entrenchment | Business processes are heavily adapted to the ERP's specific, non-standard workflows. | Untangling these processes can be more complex than the technical migration. | ||
| User Interface (UI) Complexity | Steep learning curve and poor user experience that requires extensive training and resists change. | A complex UI entrenches old habits and makes user adoption of a new system harder. | ||
| Financial & Commercial | Maintenance & Support Costs | The percentage and predictability of mandatory annual maintenance fees. | Annual fees of 18-22% on legacy systems are a major TCO driver. | |
| Forced Upgrade Cycles | Vendor mandates costly upgrades to maintain support, regardless of business need. | This puts the vendor's release schedule in control of your budget. | ||
| Total Lock-In Score | A score > 40 indicates critical risk requiring an immediate exit strategy. | |||

Plan Your Exit StrategyArchitecting the Escape Route: The Phased, Modular De-Coupling Strategy
Once you have diagnosed your dependency, the next step is to architect a viable escape plan. The single biggest mistake CEOs make at this stage is succumbing to the 'big bang' myth. A full-scale, simultaneous replacement of a core ERP system is not only incredibly risky but also unnecessary. The smarter, de-risked approach is a phased, modular decoupling strategy. This method, sometimes called the 'strangler fig' pattern, involves gradually replacing the functionality of the legacy system with new, modern components over time. You strategically 'strangle' the old system by routing more and more business processes to new, flexible modules until the legacy core is no longer critical and can be safely decommissioned.
This strategy begins by identifying the point of maximum pain or highest opportunity. Perhaps your greatest frustration is an outdated CRM, a rigid manufacturing execution system (MES), or an inability to get timely financial reports. Instead of tackling the entire ERP, you focus on replacing just that one piece of functionality with a modern, modular solution. This new module is then integrated with the remaining parts of the legacy ERP using an API-first approach. This creates an immediate win, solves a real business problem, and builds momentum and confidence within the organization for the larger transformation journey. It turns a monolithic, terrifying project into a series of manageable, value-delivering steps.
A practical example of this is a mid-market manufacturing company trapped in an old on-premises ERP. Their sales team is crippled by the lack of a mobile CRM. Using a modular strategy, they could implement ArionERP's CRM module first. This cloud-based module would be integrated to pull customer and order data from the legacy system's finance and inventory modules. The sales team gets a modern tool immediately, improving their productivity and data capture. The business sees a tangible benefit in months, not years. The next phase might be to replace the inventory management system, followed by procurement, and finally, the core financial ledger. Each step is a self-contained project with its own ROI.
The implication for a CEO is profound: you are transforming ERP modernization from a massive capital expenditure with a distant, uncertain payoff into a series of smaller, operational improvements that fund themselves. This approach dramatically lowers the risk profile of the project and makes it far more palatable to the board and investors. It allows you to maintain business continuity while systematically dismantling your dependency. The key is choosing a destination platform, like ArionERP's modular and API-first architecture, that is designed to support exactly this kind of phased, incremental transformation, giving you the flexibility to choose your own path and pace.
The Data Liberation Playbook: Your Most Valuable Asset
In any ERP hostage situation, your data is the most valuable asset being held captive. The software is replaceable, but your decades of customer history, financial records, and operational data are not. Therefore, the cornerstone of any successful exit strategy is a comprehensive data liberation and migration playbook. Many ERP migrations fail not because of technology issues, but because of a poorly planned and executed data strategy. Teams often naively assume they can simply 'export' the data from the old system and 'import' it into the new one. This overlooks the complexity, inconsistency, and proprietary nature of data locked within legacy systems.
A smarter approach prioritizes data governance and cleansing before the first module is migrated. This involves establishing a Master Data Management (MDM) strategy. The goal is to create a single, clean, and trusted source of truth for your core data entities—customers, products, suppliers, etc.—that exists independently of any single application. This 'golden record' becomes the central hub that both your legacy system and your new modular ERP will communicate with during the transition. It is a significant undertaking, but it is the single most effective way to de-risk a migration and ensure the long-term integrity of your enterprise data.
Consider a practical scenario: a company plans to move from a legacy Oracle financial system to ArionERP's modern accounting module. Instead of a direct, one-time data dump, they first implement a data cleansing project. They identify and merge thousands of duplicate customer records that have accumulated over the years. They standardize address formats and payment terms. This clean customer data is housed in a central repository. For a period, both the old Oracle system and the new ArionERP module read from and write to this master data source. When the time comes to finally switch off the Oracle finance module, the transition is seamless because the core data is already clean, validated, and in the correct format.
For the CEO, championing a data-first approach is critical. It shifts the focus from a purely technical migration to a strategic initiative to improve the quality and accessibility of a core business asset. The implications are far-reaching. By liberating your data from a proprietary silo, you not only facilitate a smoother ERP transition but also unlock its value for analytics, AI, and other digital transformation initiatives. A robust data migration strategy ensures that your new, agile ERP starts with a foundation of trusted information, preventing the classic 'garbage in, garbage out' problem that plagues so many implementations and immediately maximizing the return on your new technology investment.
Why This Fails in the Real World: Common Failure Patterns
Even with a sound strategy, ERP exit initiatives are fraught with peril. Understanding the common failure patterns is essential for any CEO who wants to navigate this journey successfully. These projects don't fail because of a single catastrophic event; they die a death of a thousand cuts, often stemming from a failure to appreciate the deep-seated complexity of the legacy environment. Intelligent, capable teams can still fail because they underestimate the non-technical, human, and process-related challenges that are inextricably linked to a decades-old system. Recognizing these pitfalls in advance is the key to proactively mitigating them.
One of the most common failure patterns is the 'Undiscovered Customization Iceberg.' On the surface, the team believes they have a standard ERP with a handful of known customizations. They create a migration plan based on this assumption. However, deep into the project, they discover a vast, submerged iceberg of undocumented custom code, shadow IT workflows, and user-developed reports that are absolutely critical for day-to-day operations. For example, the finance department's entire month-end close process might depend on a custom script written by an employee who left the company five years ago. The cost and time required to untangle and replicate this hidden logic can derail the entire project budget and timeline, causing leadership to lose faith in the initiative.
Another frequent and deadly failure pattern is the 'Last-Mile Integration Impasse.' The project team successfully migrates 95% of the company's processes to the new, modular ERP. Everything from finance to HR is running smoothly. However, the entire go-live is held hostage by a single, critical integration that proves unexpectedly difficult. This could be a connection to a proprietary piece of shop-floor machinery, a legacy EDI protocol required by your largest customer, or a link to a government reporting system with an arcane data format. The team spends months and hundreds of thousands of dollars trying to solve this 'last mile' problem, and the operational disruption of running two systems in parallel becomes unsustainable. The business loses patience, and the project is either abandoned or limps to a compromised and unsatisfactory conclusion.
These failures often happen because of a fundamental gap in governance and initial discovery. The teams fail because they didn't truly quantify the depth of the technical and process debt at the outset. They may have had a high-level strategy but lacked the granular, on-the-ground truth of how the business actually ran on the old system. Without a brutally honest assessment of the complexity—and a CEO-level commitment to see the project through the inevitable tough spots—the political will and financial resources required to overcome these final, difficult hurdles simply evaporate. This is why the diagnostic phase is not just a preliminary step but the most critical foundation for the entire endeavor.
The Financial Case for Freedom: Re-evaluating TCO Beyond the License
For a CEO, any major strategic initiative must be backed by a compelling financial case. The challenge with escaping ERP lock-in is that a simplistic comparison of license fees often makes staying put seem like the cheaper option. This is a dangerously incomplete view. The true financial argument is built on a comprehensive understanding of the Total Cost of Ownership (TCO), which extends far beyond the obvious costs. The TCO of a locked-in legacy ERP is a financial black hole, consuming budget through hidden costs that stifle growth and innovation. Making this visible is key to getting board approval for a migration strategy.
The first step is to deconstruct the real costs of your current system. This includes the hefty annual maintenance fees, which typically run 18-22% of the original license cost and often increase each year. But it goes much further. You must quantify the exorbitant cost of hiring specialized consultants required for any minor change or customization. Add the internal IT staff costs dedicated to simply keeping the aging infrastructure running. Then, and most importantly, you must estimate the opportunity cost: the new products you couldn't launch, the efficiency gains you couldn't realize, and the market share you lost because your system couldn't adapt.
A modern, modular ERP platform like ArionERP presents a fundamentally different financial model. While there is an upfront investment in implementation, the long-term TCO is significantly lower and more predictable. Subscription-based SaaS models, like ArionERP's Cloud offering, convert large, unpredictable capital expenditures into manageable operating expenses. The costs of infrastructure, maintenance, and security are bundled into the subscription, eliminating entire categories of hidden expenses. Furthermore, the use of open standards and intuitive configuration tools reduces the reliance on expensive, specialized consultants, empowering your internal team to manage and adapt the system.
The following table provides a simplified, five-year TCO comparison that illustrates this financial shift. It contrasts the typical cost structure of a locked-in legacy system with that of a modern, modular platform. Notice how the legacy costs are dominated by opaque and reactive spending (support, custom work), while the modern ERP costs are focused on predictable subscriptions and value-added activities. This framework helps a CEO reframe the conversation from 'How much will a new ERP cost?' to 'What is the real, ongoing cost of not changing?' When viewed through this strategic lens, the investment in freedom becomes not just justifiable, but financially prudent.
Decision Artifact: TCO Comparison - Legacy Lock-In vs. Modern Modular ERP
| Cost Category | Locked-In Legacy ERP (5-Year Estimate) | Modern Modular ERP like ArionERP (5-Year Estimate) | Key CEO Insight |
|---|---|---|---|
| Software Licensing & Maintenance | $1,000,000 (20% annual maintenance on $1M initial license) | $750,000 (e.g., 50 users on Professional Plan @ $480/user/yr + growth) | The legacy maintenance 'tax' often exceeds the entire subscription cost of a modern system. |
| Infrastructure & Hardware | $250,000 (Server refresh cycles, storage, database licenses) | $0 (Included in SaaS subscription) | Eliminates a major category of capital expenditure and IT overhead. |
| Implementation & Customization | $750,000 (Ongoing reliance on expensive, specialized consultants for any change) | $250,000 (Initial implementation + internal configuration) | Shifts spending from reactive fixes to a one-time strategic investment. |
| IT Personnel & Support | $1,250,000 (Dedicated team for patching, database admin, legacy support) | $500,000 (Re-focused team on value-add activities, not just 'keeping the lights on') | Frees up your best technical talent to focus on innovation. |
| Integration Costs | $300,000 (Building and maintaining brittle, point-to-point integrations) | $100,000 (Using modern APIs and pre-built connectors) | Dramatically reduces the cost and complexity of connecting to other business systems. |
| Opportunity Cost (Estimated) | $1,500,000+ (Lost revenue from inability to launch new channels, poor data insights, etc.) | $0 | This is the most critical, strategic number. The cost of inaction is often the highest cost of all. |
| Total 5-Year TCO | $5,050,000+ | $1,600,000 | The financial case for freedom is clear. The investment in a modern ERP pays for itself by eliminating hidden legacy costs. |
Life After Lock-In: Building a Future-Ready, Composable Enterprise
Escaping vendor lock-in is not merely about switching from one software provider to another; it's about fundamentally changing your company's relationship with technology. The ultimate goal is to build a 'composable enterprise.' This is a strategic approach where your digital capabilities are built from interchangeable, modular components that can be easily assembled and reassembled to meet changing business needs. Instead of being trapped within a single, monolithic system, you operate from a stable, flexible core and plug in best-of-breed applications as required. This architectural freedom is the ultimate antidote to vendor lock-in and the foundation of a truly agile, future-ready business.
In a composable enterprise, the ERP platform serves as the reliable operational backbone, not an all-encompassing cage. It handles the core, standardized processes like finance, procurement, and core HR with ruthless efficiency. For more specialized or differentiating capabilities—like advanced analytics, a customer-facing e-commerce site, or a specialized warehouse management system (WMS)—you have the freedom to choose the best tool on the market. These components are connected to the core ERP via a well-governed, API-first integration strategy. This approach, championed by industry analysts at Gartner, allows you to innovate at the edges of your business without destabilizing the core.
Imagine the practical implications. After migrating to ArionERP's modular platform, your head of manufacturing wants to implement an AI-powered predictive maintenance tool for the factory floor. In the old, locked-in world, this would have been a non-starter or a multi-year, seven-figure customization project with your legacy vendor. In your new composable environment, it's a strategic choice. You can select the best AI tool on the market and integrate it with ArionERP's maintenance and asset modules via open APIs. The project is completed in a quarter, not years, and delivers immediate value. You are now making technology decisions based purely on business value, not vendor constraints.
As CEO, your role is to champion this vision of a composable, future-ready enterprise. It represents a strategic shift from viewing technology as a fixed cost center to seeing it as a flexible enabler of business strategy. By choosing a platform like ArionERP, which is built on the principles of modularity, open integration, and deployment flexibility (On-Premises or Cloud), you are not just buying a new ERP. You are investing in your company's long-term ability to adapt, innovate, and win. This is the ultimate prize for successfully navigating the escape from vendor lock-in: a business that is no longer captive to its technology but empowered by it.
Conclusion: Your Roadmap to Strategic Freedom
The journey to escape ERP vendor lock-in is a strategic imperative, not a technical project. It is about reclaiming your company's agility, controlling its financial destiny, and building a foundation for future growth. As we've explored, this is not a path to be taken lightly, but with a clear, phased strategy, it is an achievable goal that moves your business from a position of vulnerability to one of strength. The feeling of being trapped by a legacy vendor is a common one, but it is not a permanent condition. Proactive leadership and a commitment to a structured exit plan can turn this significant business risk into a powerful competitive advantage.
To begin your journey, we recommend focusing on these four concrete actions:
- Conduct an Honest Risk Assessment: Use the Vendor Lock-In Risk Assessment Matrix, or a similar framework, to have a frank, data-driven discussion with your executive team. Quantify your risks across contractual, technical, operational, and financial dimensions to build a unified understanding of the problem.
- Develop a Phased De-Coupling Plan: Reject the 'big bang' approach. Identify the single business area suffering the most pain from your legacy system and target it for the first phase of your modular migration. Prove the value and build momentum with an early win.
- Prioritize Data Liberation: Elevate your data migration from a technical task to a strategic initiative. Invest in data cleansing and master data governance before you move a single record. Your new system's success depends entirely on the quality of the data you feed it.
- Choose a Platform Built for Freedom: When selecting your destination, prioritize a platform with a modular architecture, an API-first integration philosophy, and flexible deployment options. Your goal is not just to find a new vendor but to adopt a new, composable way of operating that prevents future lock-in.

Frequently Asked Questions
What is the primary difference between ERP configuration and customization?
Configuration involves using the ERP's built-in tools and settings to tailor the software to your business processes without changing the source code. This is a safe and supported way to adapt the system. Customization, on the other hand, involves writing new code or altering the existing source code to add functionality that the vendor did not provide. While sometimes necessary, excessive customization is a primary driver of vendor lock-in, as the custom code is often proprietary, breaks during upgrades, and makes migration to a new system incredibly difficult and expensive.
How long does a phased, modular ERP migration typically take?
While every business is different, a phased migration is a multi-stage journey. A typical timeline might see the first high-impact module (e.g., CRM or Inventory Management) go live within 6-9 months. Subsequent modules can then be rolled out every 4-6 months thereafter. A complete, multi-module transition from a complex legacy system to a modern modular platform like ArionERP could take between 18 to 36 months. The key benefit of this approach is that the business starts seeing value and ROI from the very first phase, rather than waiting years for a 'big bang' go-live.
Is a modular ERP approach more expensive than an all-in-one suite from a single vendor?
It's a common misconception that a modular or 'best-of-breed' approach is more expensive. While the initial license cost of a monolithic suite might seem straightforward, the Total Cost of Ownership (TCO) is often far higher due to hidden costs like forced upgrades, expensive customization, and integration challenges. A modular platform like ArionERP offers a more transparent and predictable cost model. You only pay for the functionality you need, and the use of open APIs dramatically reduces the cost and complexity of integrating other systems, leading to a significantly lower TCO over the long term.
Can we really run our old and new ERP systems in parallel during the transition?
Yes, running systems in parallel is a core tenet of a de-risked, phased migration strategy. This is achieved by establishing a robust integration layer between the legacy system and the new modules. For example, during the transition, a new sales order entered into the new CRM module can automatically create the corresponding financial entry in the legacy accounting system via an API. This ensures data consistency and allows the business to operate without interruption while you systematically migrate functionality. It requires careful planning but is far safer than a hard cutover.
Our most critical business processes are in custom code. How can we possibly migrate?
This is the heart of the lock-in problem and the most challenging part of an escape. The process begins with a thorough discovery phase to document what this custom code actually does for the business. Often, you'll find that much of the functionality can be replicated using the standard configuration options in a modern, flexible ERP. For the truly unique logic that represents your competitive advantage, the goal is to re-build it on an open, modern platform using standard programming languages and connect it via APIs, rather than keeping it trapped in a proprietary language. This untangles your unique 'secret sauce' from the underlying commodity ERP vendor.
