Build vs Buy: Should You Custom-Build Your AI App?
In 2026, most B2B teams spend $40,000–$120,000 over three years on SaaS seats, integrations, and workarounds. When the app is the product — your data flywheel, margins, and roadmap — a custom AI-native build often breaks even in under 3 years. Use the calculator below for your scenario.
Your scenario
Recommendation
3-year SaaS stack cost (est.)
$87,000
When to buy SaaS
- Commodity workflow (CRM, billing, email) with minimal differentiation.
- Under 20 seats and low customization — time-to-value beats ownership.
- No proprietary data loop — switching costs are low.
When to build custom
- The software is the business model (marketplaces, AI copilots, games).
- You need deep AI features competitors cannot replicate from a SaaS API.
- Multi-year SaaS + integration spend exceeds ~$60k — custom build ROI flips positive.
