Payment Gateway & Subscription Integration
Payment Gateway, Subscription & Billing Integration
Stripe, PayPal, Apple Pay and regional gateways integrated properly — plus subscriptions, deposits, invoicing and marketplace payouts.
Payments That Work the Way Your Business Does
Taking a payment sounds simple until you need something the standard checkout does not do: a deposit now and the balance later, a subscription with a free month, split payments to several sellers, a gateway your customers in another country actually trust, or a smooth move away from a provider whose fees have crept up.
We integrate payments across websites, stores and mobile apps, and we do it in a way that keeps you out of card-data scope: tokens and hosted fields, never raw card numbers on your server. Failed payments, refunds, disputes and webhooks are handled as carefully as the happy path, because that is where money is actually lost.
What’s Included
What We Integrate
Card & Wallet Payments
Stripe, PayPal, Braintree, Adyen and regional gateways, with Apple Pay and Google Pay for one-tap checkout on mobile.
Subscriptions & Recurring Billing
Trials, plan changes, proration, dunning for failed renewals and customer self-service — on Stripe Billing, WooCommerce Subscriptions or Shopify.
Deposits, Instalments & Invoicing
Part-payments, pay-later balances, payment links and invoices for businesses that do not sell off a shelf.
Marketplace & Split Payouts
Stripe Connect and similar for platforms that collect from buyers and pay out to sellers or partners.
Webhooks & Reconciliation
Orders, refunds and disputes kept in sync between the gateway, your site and your accounting system.
Gateway Migrations
Moving providers without interrupting active subscriptions or forcing customers to re-enter cards.
Benefits
Why the Integration Matters
- Higher conversion: wallets and a fast, familiar checkout remove the last-minute drop-off.
- Lower risk: no card data touches your systems, so PCI compliance stays simple.
- Fewer lost renewals: retry logic and reminders recover a large share of failed subscription payments.
- Accurate books: every transaction, refund and fee reconciled automatically.
- Freedom to switch: a clean integration means you are not locked to one provider’s pricing.

FAQ
Payment Gateway & Subscription Integration FAQs
Which payment gateway should I use?
For most businesses Stripe is the best starting point: broad country support, excellent subscriptions and clear pricing. PayPal is worth adding for the customers who prefer it. If you sell mainly in one region, a local gateway can lift conversion noticeably — we will recommend based on where your customers are.
Can you add subscriptions to my existing store?
Yes, on WooCommerce, Shopify and custom platforms. The important decisions are around trials, upgrades and what happens when a renewal fails; we design those flows with you before building.
Is taking payments on my site secure?
When integrated properly, card details go straight from the customer’s browser to the gateway and never reach your server, which keeps you out of the heaviest PCI requirements. We build every integration this way.
Can I move gateways without losing my subscribers?
Usually yes. Most major gateways support exporting saved payment methods securely to another provider, so active subscriptions continue without customers re-entering details. We manage the transfer and test it before switching.

Keeping Subscribers When Payments Fail: Retries, Dunning, Pauses and SCA
Many lost subscribers never chose to leave: their card expired or a renewal needed authentication nobody asked for. Here is how we set up subscription billing to recover failed payments, with sensible retries, dunning emails people act on, card updates, SCA handling and pause and skip options.
