( decision framework )
Buy the commodity, build the advantage.
Off-the-shelf wins for standard, well-covered needs. Custom wins where the software is your product or your unfair advantage.
Build
Consider when the software is core to your business, requirements are differentiated, no product fits well, or you need full ownership and control.

Questions buyers ask
What does build vs buy mean for software?
Building means you develop custom software yourself or with a team. Buying means you license an existing product, SaaS, or platform. The decision balances control, cost, speed, and ongoing upkeep.
When should I buy instead of build?
Buy when the functionality is a commodity, a good off-the-shelf product exists, your requirements are standard, and time-to-market or cost is the priority.
When does building software make sense?
Build when your requirements are genuinely differentiated, you need full control and ownership, you expect to scale around the feature, or no good product fits.
What are hidden costs of buying SaaS?
Subscription fees compound over time, but they include maintenance and upgrades. Watch for per-user pricing, integration limits, lock-in, and features you pay for but never use.
What are hidden costs of building?
Build costs go beyond development: hosting, maintenance, security, support, and continuous improvements all add up over the product's life.
