The 12 weeks reality

If you're a founder targeting interior designers and you want a working invoicing saas MVP in 12 weeks, the question isn't "can we build it?" — it's "what gets cut so we ship?". Quote, invoice, and collect — without leaving the job.

Twelve weeks gives you room for deeper workflows, two-three integrations, and a real beta cohort — without the open-ended timeline that kills most v1s.

By the end of 12 weeks you have a multi-tenant invoicing saas live in production, Stripe billing wired up, your first design partners onboarded, and a roadmap shaped by real usage instead of hypotheses.

Founder FAQs

Is 12 weeks really enough to launch an invoicing saas?+

Yes — when scope is cut to the wedge and demos ship every week. We've launched MVPs for interior designers founders in 12 weeks multiple times. The trick isn't building faster, it's saying no to features that don't matter for the first 10 customers.

What if we miss the 12 weeks deadline?+

Scope is fixed in week 1, so the only way to slip is scope creep — which we flag immediately. If something genuinely surprises us, we re-quote transparently and you can decide to push the date or cut scope.

How much does an invoicing saas MVP cost in 12 weeks?+

Fixed-price after week 1 discovery. The number depends on integrations and surface area — we quote a range in the founder call and a hard number after the sprint. Most founders pay less than 6 months of two-engineer salaries for a production MVP.

What stack will you use?+

TypeScript end-to-end (React + Node/Edge), Postgres, Stripe, a serverless or edge platform. The result is something your in-house team can pick up without retraining and that scales without rearchitecting.

Do we own everything?+

Yes — source code, database, infrastructure config, design files, and the domain are yours from day one. No vendor lock-in.
