One workflow. One system. Fixed price. That is how SaaS founders avoid open-ended dev spend.
How fixed-scope pricing works
- Workflow mapped and written down before build starts.
- Deliverables tied to acceptance criteria.
- 50% upfront, 50% on handover (cash flow aligned to delivery).
- Change requests = new phase, not silent scope creep.
Typical fixed-scope pricing
One product phase at a time: MVP workflow, onboarding flow, customer portal, admin dashboard or reporting slice.
- SaaS build: from £5,000, shipped from 14 days (customer accounts, onboarding, workspace, admin dashboard, product workflow, Stripe, transactional email, integrations, reporting and deployment).
- Enterprise: from £18,000, shipped in 30 days (compliance, SSO, unlimited screens).
Use this as a working checklist inside your team first. When the same steps repeat every week and spreadsheets start breaking, that is usually the moment to scope a fixed-scope phase with deliverables, acceptance criteria and ownership terms agreed upfront as an owned system.
