Planning a SaaS MVP starts with the workflow, integrations, and release requirements. This guide uses an illustrative budget for the base scope below, with the decisions that can change the estimate. A project-specific quote follows a scope review.

€6,000–€22,000
Planning estimate in EUR for the base scope below. A written quote confirms the price, tax treatment, and payment terms.
6–14 weeks
Depends on agreed scope, access to services, feedback, and release requirements. Confirm availability and milestones before scheduling.
Share the main user workflow, required integrations, existing assets, and target platforms. We can then separate the first release from later features.
These figures are planning assumptions, not market averages, a fixed offer, or a guaranteed delivery date. Ongoing services and maintenance need a separate budget unless included in the proposal.
Write down one complete journey: create an account, complete the core task, and pay for continued access. Define tenant boundaries and roles before estimating screens. A simple-looking dashboard can still require complex permission checks.
List trials, plan changes, failed payments, refunds, and account cancellation. Decide which events change access. Test repeated and delayed webhooks, not just the successful checkout. Advanced billing and internal admin tools need their own scope.
Give each developer or team the same workflows, integrations, acceptance criteria, and release responsibilities. Ask what is excluded and how changes are priced. Compare handover documentation, testing, support, and recurring service costs alongside the build price.
Hosting, payment processing, email or SMS, third-party subscriptions, and ongoing maintenance should be budgeted separately unless explicitly included in the written proposal. Confirm current provider pricing for your expected usage and region. The planning range on this page is not a market survey or a fixed offer.
This guide uses an illustrative €6,000–€22,000 build budget for the listed base scope. The final quote depends on requirements, integrations, and acceptance criteria; it may fall outside this range.
The planning window is 6–14 weeks for the listed scope. Availability, feedback, dependencies, and release approvals affect the schedule. Milestones are agreed after the scope review.
My case studies cover BookBed, a multi-property booking product built with Flutter and Firebase, and Callidus, a clinic platform built with React and Firebase. They show the implementation behind the estimate: tenant isolation, calendar workflows, and billing integrations.
