Build vs. Buy: Why Returns Management Isn’t the Place to Take Shortcuts
There is a real shift in how companies think about software. Not long ago, the build or buy decision was fairly simple. Buying software meant speed, stability and shared cost. Building meant control, customization and long-term investment. AI-assisted development, and what many now call “vibe coding”, has changed that equation.
Teams can now move from idea to working prototype in hours instead of months. The barrier to building software has dropped, and for the first time it feels realistic for mid-sized companies to ask why they should not build it themselves. In some cases that instinct is right. In returns it is not.
The Appeal of Speed
AI has made one part of software development very fast: writing code. It is now possible to generate interfaces, connect APIs and deploy lightweight applications in a fraction of the time it used to take. Even non-engineers can create working tools by describing what they want in plain language.
That creates a dangerous illusion, which is that building the software is the hard part. What AI speeds up is the visible layer: the UI, the workflow, the initial functionality. It does not solve what sits underneath: architecture, reliability, integration, compliance and long-term maintainability.
Many teams are finding that AI speeds up development and also introduces new risks. AI-generated code often contains more errors and more security vulnerabilities, and takes more effort to maintain, especially when the team does not fully understand what was generated. You can build something quickly. That does not mean you have built something that works.
Returns Look Simple Until They Are Not
Returns are one of the most misunderstood areas in enterprise software. On the surface the workflow seems simple: a customer submits a return, it gets approved, and a refund is issued. That is the version most teams imagine when they decide to build. It is not how returns operate in a real business.
Returns sit where operations, customer experience and finance meet. They touch nearly every system and every process. What starts as a “simple return” quickly becomes a network of dependencies:
- Orders need to be validated across channels.
- Warranty eligibility must be checked.
- Returns may require approvals based on product type, condition or customer tier.
- Items need to be routed, not only back to a warehouse but potentially to a store, a repair center or a third-party partner.
Once the product arrives, the real work begins: inspection, grading, disposition, repair, resale or recycling, all tied back to financial reconciliation, inventory updates and customer communication. That is a system, not a workflow.
The Complexity You Do Not See on Day One
Most internal builds do not fail in version one. They fail in everything that comes after. The initial build might take weeks, but that is a fraction of the total cost. Most of the effort comes later: maintaining integrations, fixing edge cases, adapting to new requirements and managing the growing complexity of the system.
Returns are particularly unforgiving here. Every integration, whether ERP, WMS, OMS or carriers, needs ongoing maintenance. APIs change. Business rules evolve. New channels get added. What worked six months ago quietly breaks.
Regulatory pressure keeps increasing as well. Data privacy requirements like GDPR, consumer protection laws such as the EU’s 14-day right of withdrawal, right-to-repair legislation, and increasingly complex B2B claims and entitlement rules all add layers of compliance that most internal systems are not designed to handle. These are not edge cases. They are the operating environment.
The Risk Is to the Business, Not Only the Technology
There is also a misunderstanding about where returns sit in the business. Returns are a customer-facing system, not a back-office tool. When a returns experience breaks, customers feel it immediately. Refund delays, incorrect approvals and lost items are not internal issues. They affect customer trust, support volume and brand perception.
This is not the place to experiment with “good enough.” Yet that is often what internal builds become, especially those accelerated by AI: fast to start, difficult to scale and increasingly fragile over time.
What Companies Are Doing
Even among large enterprises embracing AI, a clear pattern is emerging. Companies are not replacing core operational systems with AI-built alternatives. They are using AI to extend existing platforms, not rebuild them from scratch. Systems like ERP, WMS and OMS are foundational. They need stability, compliance and long-term support, and they are too critical and too complex to be treated as experimental builds. Returns management belongs in the same category.
The ERP Test
A simple way to test the build or buy decision: would you build your own ERP? Would you build your own warehouse management system? Almost no company would. That is not for lack of ability. It is because they understand the cost, risk and ongoing commitment of owning that system. Returns management is no different. It may look smaller on the surface, but in practice it carries the same operational complexity, integration depth and business impact.
Where Building Still Makes Sense
Building is not always the wrong choice. If your returns process is simple, with low volume, limited channels and minimal integration, a lightweight internal solution can work, and AI has made that more accessible than ever. That window closes quickly. As soon as you add multiple channels, multiple systems, warranty workflows or meaningful scale, you are no longer building a feature. You are building infrastructure, and infrastructure is where shortcuts fail.
Why Purpose-Built Solutions Exist
Dedicated returns platforms exist because maintaining a returns system is far more complex than it appears, not because companies cannot build one. Purpose-built solutions are designed to handle:
- Real-world workflow complexity
- Deep system integrations
- Ongoing regulatory change
- Continuous optimization
They absorb that complexity so your team does not have to. They also let your organization focus on improving returns as a business function, by reducing costs, improving recovery and improving the customer experience, instead of maintaining the plumbing behind it.
Final Thought
AI has changed how software gets built. It has not changed the complexity of the problems businesses need to solve, and returns are one of those problems. They sit where systems, workflows, regulations and customer experience meet. They change constantly, and when they fail, the impact is immediate. The real challenge is not building returns software. It is running it.
