Service details

Payment systems and API connections, built for real money

Need a payment flow that a ready made plugin cannot handle? Escrow for a marketplace, split payments with your commission, money held until a job is done, or a connection between your WordPress site and another system? That is the custom work I do.

I built the payment system for a booking marketplace in South Africa from the ground up: its own plugin, its own connection to a licensed escrow provider, and the full payment flow. Organisers pay into escrow, the money is held until the event is confirmed with a one time code, and the platform commission is split off automatically. It is live and takes real card payments.

Every flow is built and tested in the provider sandbox first. Every payment status is checked back with the provider before anything changes on your site, so a fake or failed message can never mark an order as paid.

What I build

  1. Payment provider connections with checkout, success and failure pages
  2. Escrow and split payments for marketplaces, with your commission taken automatically
  3. Webhooks that update orders, bookings and dashboards when a payment changes
  4. Release, cancellation and refund rules written to your own policy
  5. Custom WordPress plugins and REST API endpoints
  6. Connections between WordPress and outside systems, such as a CRM or booking tool

How it works

  1. You tell me your provider, your country and how the money should move
  2. I map every payment state before I write any code
  3. I build and test everything in the provider sandbox
  4. We switch to live keys together and run a real test payment

Send me a message with your payment provider, your country and what should happen to the money at each step, and I will tell you which package fits before you order.

Special note from freelancer
Built on real experience: I designed a live escrow payment flow for a booking marketplace. Every build is tested in the provider sandbox first, and every payment is checked with the provider before your site trusts it.

FAQs

Any provider with a documented API and a test mode. I built a full escrow flow on a South African escrow provider and have set up PayPal and Stripe payouts. Tell me your provider and country and I will confirm before you order.
