Launch a Subscription Billing SaaS MVP in 6 Weeks for Med Spas.
Run subscription pricing, trials, and dunning without a billing engineer. Fixed scope, billing wired from day one, you own the code.




If you're a founder targeting med spas and you want a working subscription billing saas MVP in 6 weeks, the question isn't "can we build it?" — it's "what gets cut so we ship?". Run subscription pricing, trials, and dunning without a billing engineer.
Six weeks is the sweet spot for most founders — enough time to ship a real multi-tenant MVP without losing the urgency that keeps scope honest.
By the end of 6 weeks you have a multi-tenant subscription billing saas live in production, Stripe billing wired up, your first design partners onboarded, and a roadmap shaped by real usage instead of hypotheses.

Is 6 weeks really enough to launch a subscription billing saas?+
Yes — when scope is cut to the wedge and demos ship every week. We've launched MVPs for med spas founders in 6 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 6 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 a subscription billing saas MVP cost in 6 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.
Real builds we've shipped
We don't just write playbooks — we ship them. A few production launches from the Envert team.
