Choosing and wiring the gateway
Stripe, Square, Braintree, Authorize.net, Adyen — the right gateway depends on your business model, where your customers are, and what payment types you need. We integrate the one that fits rather than pushing a default.
The core work is more than a checkout button: it's tokenizing cards so you never touch raw card data, handling the full payment lifecycle, and reconciling what actually happened through webhooks.
- Card, ACH/bank transfer, Apple Pay, Google Pay, and other wallets as needed
- Hosted fields or a hosted checkout so card data never hits your server
- Webhook handling for succeeded, failed, refunded, disputed, and pending events
- Idempotency so a retried request never double-charges a customer
- One-time payments, saved cards, or subscriptions and recurring billing
The parts people forget
The happy-path charge is the easy part. Production payments live or die on the edge cases: a card declined mid-checkout, a webhook that arrives twice, a refund that has to reverse the right records, a chargeback you need to log and answer.
- Failed and retried payments, partial captures, and voids
- Refunds and partial refunds that stay in sync with your own records
- Disputes and chargebacks surfaced so your team can respond in time
- Receipts, invoices, and tax handling where applicable
- Reconciliation between the gateway's ledger and your database
- Clear, honest error messages to the customer at the point of failure
Security and compliance, done right
We keep your PCI scope as small as possible by never storing raw card numbers — the gateway tokenizes them, and you store only the token. We're a development agency, not a compliance auditor, so we build to the gateway's best practices and point you to the certification path when you need formal attestation.
- Tokenization so raw card data never lands in your database
- HTTPS everywhere and secrets kept out of client-side code
- Webhook signature verification so events can't be spoofed
- Minimal PCI scope via hosted fields or SDK-provided UI
- Guidance on your SAQ level — with the honest note that formal compliance is yours to complete

Frequently asked questions
Which payment processor should we use?
It depends on your customers and model. Stripe is a strong default for online products and subscriptions; Square suits in-person plus online; others win on international coverage or specific rates. Tell us your customers, currencies, and whether you're recurring or one-time, and we'll recommend based on that, not habit.
Do you handle PCI compliance?
We build so that raw card data never touches your servers, which keeps your PCI scope small and simplifies compliance. But formal PCI attestation is a certification you complete with your provider — we set you up to pass it, we don't sign off on it for you.
Can you add subscriptions and saved cards?
Yes — recurring billing, saved payment methods, plan changes, prorations, and dunning for failed renewals are all standard gateway features we wire up. We'll map your pricing model to the gateway's subscription tools during scoping.
