The verdict in three sentences
A shift scheduling SaaS for restaurants can launch with an MVP at EUR 20,000 to 45,000 delivered in 10 to 14 weeks, provided the first version is limited to a single promise: publishing next week's rota in 15 minutes. The multi-tenant architecture and Stripe subscription must be there from day one, because retrofitting them later costs more than building them now. With grant funding (in France, Bpifrance's French Tech grant reaches EUR 30,000; in the UK, Innovate UK and the Start Up Loans scheme play a similar role) and hosting at EUR 50 to 150 per month, a non-technical founder can reach paying customers without raising funds.
What a useful MVP contains, and what can wait
A restaurant manager spends 3 to 4 hours a week on the rota on average, between spreadsheets, WhatsApp groups and last-minute shift swaps. The MVP must solve that problem, not the whole HR job.
| Feature | In the MVP | Why |
|---|---|---|
| Drag-and-drop rota builder | Yes | It is the core promise |
| Week templates and duplication | Yes | Cuts entry time by 3 |
| Employee mobile app (PWA) | Yes | Viewing the rota and notifications |
| Shift swap requests | Yes | Removes most WhatsApp messages |
| Hours counter and alert above 48 h | Yes | Strong legal constraint (Working Time Regulations) |
| Stripe subscription and 14-day trial | Yes | Collect revenue from the first client |
| Payroll export | Version 2 | Formats differ by payroll software |
| Time clock and geolocation | Version 2 | Requires hardware and a GDPR review |
| AI staffing forecasts | Version 3 | Needs several months of data |
Budget and 14-week schedule
| Phase | Weeks | Deliverables | Budget excl. tax (estimate) |
|---|---|---|---|
| Scoping and mock-ups | 1 to 2 | User flows, 12 screens, tests with 5 managers | EUR 3,000 to 6,000 |
| Multi-tenant core | 3 to 4 | Accounts, venues, roles, data isolation | EUR 4,000 to 8,000 |
| Rota and rules | 5 to 8 | Editor, templates, counters, alerts | EUR 6,000 to 14,000 |
| Employee app | 9 to 10 | PWA, notifications, shift swaps | EUR 3,000 to 8,000 |
| Subscription and billing | 11 | Stripe Billing, trial, plan changes | EUR 2,000 to 4,000 |
| Testing, beta and launch | 12 to 14 | 10 beta restaurants, fixes, go-live | EUR 2,000 to 5,000 |
| Total | 10 to 14 | EUR 20,000 to 45,000 |
Recurring costs stay low at first: EUR 50 to 150 per month of hosting and database for the first 100 clients, plus 1.5% + EUR 0.25 per Stripe payment on European cards and 0.7% for Stripe Billing. Also plan EUR 500 to 1,200 per month of ongoing development once the product is live.
Multi-tenancy means all clients share the same application with strict data separation. Planning it in week 3 costs a few days; adding it after 50 clients can cost EUR 8,000 to 15,000.
Funding without raising capital
| Source | Possible amount | Main conditions |
|---|---|---|
| Bpifrance French Tech grant (France) | Up to EUR 30,000 | Company under one year old, innovative project, max 70% of costs |
| Innovate UK Smart grants (UK) | Variable, competitive | Innovative project, co-funding required |
| Start Up Loans (UK) | Up to about EUR 29,000 (GBP 25,000) | Personal loan to the founder, fixed 6% rate, mentoring |
| Pre-sales to pilot restaurants | 10 x EUR 500 | Prepaid annual plan with discount |
Local accelerators and university incubators often complete this plan.

Max, a former restaurant floor manager turned founder in London, commissions an MVP at EUR 38,000. Grant funding covers EUR 26,600, or 70% of the spend, and a EUR 20,000 founder loan covers the rest plus 6 months of running costs. He charges EUR 89 per month per venue.
With 10 beta restaurants converted at launch, then 8 new clients a month, he reaches 58 venues after 6 months, or EUR 5,160 of monthly recurring revenue. His fixed costs (hosting EUR 120, maintenance EUR 900, tools EUR 200) are EUR 1,220 a month: margin covers costs from month three, and his own share of the MVP, EUR 11,400, is absorbed in under 5 months of margin.
FAQ
Can a no-code tool build the MVP for less?
Yes to test interest, for EUR 3,000 to 8,000. However, fine-grained working-hours rules and multi-tenancy quickly hit no-code limits, and the later migration often costs EUR 15,000 or more.
Who owns the MVP code?
Your company, through an assignment of rights in the contract. Funders and any future investor will expect it.
How many restaurants should be in the beta?
Ten are enough to validate the product, provided they cover two profiles: independent restaurants and small chains of 3 to 5 venues. Aim for 7 paying conversions out of 10 at the end of the beta.
What if the 14-week timeline slips?
The contract schedule sets milestones every two weeks with a demo. Non-critical features move to version 2 rather than delaying launch.
