I will integrate or fix stripe paypal or razorpay payments in your flutter app

Stripe, PayPal and Razorpay, where supported for your business, country, currency and Flutter project. Each package covers one agreed gateway. Please message me first so I can check provider eligibility and your existing app/backend.

Basic fixes one agreed bug in an existing payment flow. Standard adds one gateway, one checkout and a Node.js or Firebase verification/webhook flow on one platform. Premium covers Android and iOS, one refund endpoint, duplicate-event handling and one backend deployment.

Basic and Standard cover Android OR iOS, as agreed before ordering. Premium covers both for the same Flutter app and payment flow. You must provide a buildable project and the required signing/test access. Flutter Web needs a separate quote.

Subscriptions are scoped separately from these checkout packages. One eligible recurring plan can be added after review. Trials, proration, upgrades or a complete billing lifecycle need a custom offer. Digital goods may require Apple/Google in-app billing.

Standard and Premium include the agreed Node.js or Firebase backend payment flow, with server-side verification and signed webhook handling. Secret keys stay on the backend. Basic repairs an existing flow; a new backend, other stacks or wider backend changes need a custom quote.

All packages include the changed source code, test notes and handover instructions for the agreed work, plus 7 days of support for defects in that delivered payment flow. Revisions stay within the agreed scope; new features and unrelated bugs need a separate quote.

I can configure the agreed flow for your own approved merchant account. Premium includes one backend deployment; other launch work is quoted separately. Account approval, transaction acceptance, provider fees and store review decisions are controlled by the provider or app store.

Share the relevant source/repository, setup instructions and sandbox access using scoped developer permissions. Keep passwords, live secret keys and customer payment data out of chat. Production secrets should be entered directly in your hosting environment by you.

Yes. Each package covers one gateway and one checkout flow. An additional supported gateway can be scoped as an extra or custom offer after reviewing your backend, currency and platforms. Marketplace split payouts and Stripe Connect require a separate quote.

No. These packages cover external gateways for eligible goods/services. Apple/Google digital-goods billing requires separate scope. Store submission is optional and quoted separately; approval is not guaranteed. Message me with your business type and target stores before ordering.
