Build vs Buy Enterprise Software: How to Decide
Buy when the workflow is standard across your industry and doesn't differentiate you competitively — payroll, email, standard CRM functionality. Build when the capability is a genuine competitive differentiator, no vendor solution fits your specific workflow, or you'd need so much customization to an off-the-shelf product that you're effectively building anyway. Most companies get this backwards in both directions: buying commodity software custom-built and building differentiating capability on a rigid off-the-shelf platform that fights the actual requirement.
What's the real test for whether to build?
The test isn't "could we build this" — almost anything can be built. The test is whether the capability is actually a competitive differentiator for your business, meaning customers or revenue would meaningfully change if you did it better than competitors. A logistics company's core routing algorithm is worth building because it's genuinely differentiating. That same company's expense reporting system almost certainly isn't — better expense reporting doesn't win customers, so buying a standard tool and directing engineering effort toward the differentiating capability is the higher-leverage choice.
What's the hidden cost of buying the wrong tool?
The sticker price of an off-the-shelf tool is rarely the real cost when the tool doesn't fit your actual workflow. The hidden cost shows up as constant workarounds, manual processes to bridge gaps the tool doesn't cover, and the accumulated productivity tax of forcing a team to work around software rather than with it. When customization requirements grow large enough — heavy scripting, extensive API integration work, workflow bypasses — you're often paying licensing fees for a platform while also paying engineering costs to make it fit, which frequently exceeds the cost of building a purpose-built solution from the start.
What's the hidden cost of building the wrong thing?
Building commodity software — the same category of tool available and well-supported from established vendors — means ongoing maintenance burden your team carries indefinitely for a capability that doesn't differentiate you. Every hour spent maintaining an internally built payroll system or CRM is an hour not spent on whatever actually drives revenue, and unlike a vendor's product, an internal tool typically has no dedicated team keeping it current with regulatory changes, security patches, and integrations to new platforms.
Decision framework
| Situation | Recommendation |
|---|---|
| Standard workflow, no differentiation | Buy |
| Core competitive differentiator | Build |
| No vendor solution fits the actual workflow | Build |
| Heavy customization needed to an off-the-shelf tool | Evaluate build — may already be effectively building |
| Well-served commodity category (payroll, email) | Buy |
What Code Ninety does
Code Ninety's discovery phase includes an honest assessment of whether a client's proposed build is actually a differentiator worth custom engineering, or a commodity capability better served by an existing vendor — recommending against a build that doesn't serve the client's actual competitive position isn't in either party's long-term interest, even when it means a smaller initial engagement.
