FAQs

SaaS development, answered.

How long to launch a SaaS MVP in the UK?

10–14 weeks for a well-scoped MVP with auth, billing, core feature and admin.

What does a SaaS MVP include?

Sign-up, login, subscription billing, one core feature that solves the paying problem, admin dashboard, basic analytics, landing page. No more, no less.

Do I need multi-tenant architecture from day one?

If you plan to sell to businesses, yes. Retrofitting tenancy later is expensive and risky.

Should I use Stripe, Paddle or Chargebee?

Stripe for most UK/global SaaS. Paddle if you want the merchant-of-record handling global tax. Chargebee when billing gets complex (enterprise, quotes, multi-currency invoicing).

Who will own the code?

You do, from commit one. Private repo transferred to your GitHub org.

Can you help after launch?

Yes — monthly retainer covers feature releases, infra, on-call and product growth engineering.
