Payments are where an MVP becomes a business. A waitlist tells you people are interested. Stripe tells you whether they are willing to pay.
For non-technical founders, Stripe can feel like a technical detail, but the decisions around pricing, access, refunds, and account ownership are business decisions too.
Key takeaways
What Stripe handles
Stripe can handle checkout, cards, subscriptions, invoices, customer records, refunds, and payment status.
Use your own Stripe account
Your payments should go through your Stripe account, not the developer's.
What to prepare before build
Prepare the product name, price, billing interval, refund policy, legal pages, and what access a paying user should receive.
Where founders get stuck
Founders often treat payments as a final add-on, but payment state affects onboarding, permissions, emails, dashboards, and support.
What Stripe handles
Stripe can handle checkout, cards, subscriptions, invoices, customer records, refunds, and payment status. Your app still needs to connect those payments to the right user access.
That connection matters. If someone pays, the app should unlock the right product. If they cancel, the app should respond correctly.
Use your own Stripe account
Your payments should go through your Stripe account, not the developer's. That gives you control over customers, payouts, refunds, tax settings, and subscription records.
If a developer is helping, they can be added with the right permissions during the build and removed later.
What to prepare before build
Prepare the product name, price, billing interval, refund policy, legal pages, and what access a paying user should receive. These details affect the app workflow.
You do not need every pricing experiment ready. One clear paid offer is enough for the first MVP.

Build with Kat includes payment setup where relevant, so the MVP can launch as a real paid product instead of a demo that still needs business wiring.

Bring the idea, audience, and current workaround. I will help decide what belongs in version one, what should wait, and whether a fixed-price build makes sense.
