Founders ask whether to sign fixed-price or hourly contracts. Each model fits different risk profiles.
Fixed price — best when
- Scope is definable in a discovery sprint
- You want budget certainty for MVPs and modules
- Milestone payments align with demos
Hourly / retainer — best when
- Research-heavy or evolving R&D work
- Ongoing maintenance and small enhancements
- You need a embedded team extension
Most CSNexa product builds use fixed pricing; retainers for dedicated squads. See pricing and SaaS development services.
