Custom SaaS vs ready-made SaaS is a strategy choice: speed and lower upfront cost versus differentiation and control.
Quick answer
Buy ready-made when a product already covers ~80% of your need. Build custom SaaS when your workflow is the product, compliance forces it, or margins depend on owning the platform. Related: SaaS vs custom software.
Ready-made wins when
- You need CRM, accounting or helpdesk basics fast
- You can adapt process to the tool
- Integration APIs are good enough
- You want predictable subscription pricing
Custom SaaS wins when
- You will sell the software to many customers
- Workflows are unique and create competitive edge
- Data residency or deep ERP hooks are mandatory
- Per-seat SaaS fees will exceed build cost in 18–24 months
Hybrid path many teams miss
Use ready-made for commodity (email, payments, auth) and build the differentiated core. That is how many SaaS products ship faster without reinventing everything.
Decision checklist
- List must-have workflows
- Trial two ready-made tools for two weeks
- Estimate 24-month subscription total
- Estimate custom MVP with a partner like Altron
- Choose the option that protects revenue, not ego
