Start with the business constraint
Buy when the workflow is common, the provider meets security and integration needs, and speed matters more than differentiation. Build when the workflow is central to your advantage, unavailable in the market or impossible to adapt safely.
The answer can also be hybrid: buy infrastructure and build the distinctive workflow.
Compare total cost of ownership
Buying includes subscription increases, migration limits, vendor risk, integration work and internal training. Building includes discovery, delivery, infrastructure, maintenance, security and the cost of owning decisions.
Compare the cost over the period in which the system will matter, not only the first invoice.
Decision framework
Score the options against strategic differentiation, time to value, data sensitivity, integration depth, workflow fit, internal capability and exit risk. Write down which assumptions would change the decision.
A reversible next step
Before committing to a large build, prototype the risky workflow or integrate a small slice. Before buying a complex platform, test the provider’s data export, permissions and API behavior.
Common questions
Can DevNexia help scope this work?
Yes. Share your goals, current product and constraints through the free assessment form and we can suggest a practical next step.
Are the costs and timelines guaranteed?
No. Custom software estimates depend on scope, integrations, team shape and feedback. A written estimate becomes more useful after requirements are understood.
