Custom payment workflows beyond the default plugin model.
We design and implement payment systems for businesses that need more than an out-of-the-box checkout. That includes hosted checkout flows, processor integrations, refund logic, webhook handling, reconciliation workflows, and the infrastructure behind how money moves through the business.
Payment work is rarely just about accepting a card. It usually touches checkout UX, backend logic, transaction state, operational support, and platform boundaries. We build with all of that in mind.

Example
Project 501
Payment work that spans more than the checkout surface.
The work usually spans both customer-facing checkout behavior and the backend payment logic required to keep transaction state, settlement, and support workflows reliable.
- Hosted checkout integrations
- Processor integrations
- Refund systems
- Settlement and reconciliation workflows
- Webhook and event-based payment handling
- Transaction mapping and payment operations logic
Where businesses usually hit the limit of the default setup.
This service usually becomes necessary when the payment flow looks acceptable on the surface but breaks down once refunds, cross-system state, operational support, or platform-specific requirements come into play.
- The default payment setup does not fit the workflow
- Multiple platforms need to share payment state
- Refund handling is manual or unreliable
- Webhook or processor events are not being handled cleanly
- The checkout flow works on the surface but fails operationally underneath
- Payment infrastructure needs to be extended without rebuilding the whole stack
Payment infrastructure built across checkout, events, refunds, and supportability.
The work usually spans both customer-facing checkout behavior and the backend payment logic required to keep transaction state, settlement, and support workflows reliable.
- Clover integrations
- Stripe integrations
- Custom PSP workflows
- Hosted checkout implementation
- Refund flow architecture
- Payment state and transaction mapping
- Webhook processing and validation
- Payment support tooling
Strongest fit for businesses with real payment workflow complexity.
This service is usually most valuable when checkout and fulfillment depend on multiple systems behaving reliably together and a basic plugin model is not enough.
- Have custom payment requirements
- Rely on multiple systems around checkout and fulfillment
- Need more reliable refund and settlement workflows
- Are trying to connect commerce systems to processor-specific infrastructure
Common environments around this kind of work.
These are the platforms and system concerns that typically surround custom payment integration work.
Project 501
Custom Wix + Clover Payment Integration
A custom Wix + Clover payment integration built around hosted checkout, transaction mapping, webhook settlement handling, refund logic, and operational visibility.
Project 501 is a clear example of payment integration work extending beyond checkout into refund handling, transaction state, and day-to-day operational support.
Design the infrastructure around checkout, refunds, settlement, and support.
If your payment requirements go beyond a standard plugin install, we can help design and build the infrastructure around checkout, refunds, settlement, and support.
