What this covers
Taking a card payment is easy to demo and surprisingly easy to get wrong in production. Failed payments, refunds, disputes, subscription upgrades halfway through a month, duplicate charges from a double click, and webhooks arriving out of order all need handling.
We use hosted payment components from providers like Stripe, so card details never touch your servers. That keeps your PCI compliance burden minimal. Then we build the logic around it: what happens in your system when a payment succeeds, fails, is refunded, or is disputed.
For platforms and marketplaces, we set up split payments and payouts using tools like Stripe Connect, including seller onboarding and identity checks.
Is this right for you?
You'll get the most out of it if any of these sound familiar:
- You need to take payments in a custom app or booking system.
- You're adding subscriptions or memberships.
- Your current setup misses failed payments or double-charges customers.
- You run a platform that needs to pay out to sellers or providers.

How it works

What affects the price
Every quote is fixed and written down before work starts. These are the things that move it:
- One-time payments versus subscriptions
- Marketplace payouts
- Number of currencies and payment methods
- Integration with accounting or invoicing tools
Mistakes we plan around
The problems we see most often when this work is rushed:
- Handling raw card numbers on your own server.
- Trusting the browser's redirect instead of webhooks to confirm payment.
- No plan for failed subscription renewals.
Payment Integration questions
Which payment provider should we use?
Stripe for most custom sites and apps, because of its documentation and features. PayPal as an additional option many shoppers expect. Square if you also sell in person.
Do we need to be PCI compliant?
Every business taking cards has some PCI responsibility, but using hosted payment fields keeps it to the simplest level, because card data goes straight to the provider.
Can you set up subscriptions and recurring billing?
Yes, including trials, upgrades and downgrades, proration, and automatic retries for failed renewals.
Can you integrate payments with our accounting software?
Yes. We sync payments and refunds with QuickBooks, Xero, and similar tools.
