Custom Payment System Development
Payment functionality often needs more than a checkout button. Applications may need transaction states, invoices, refunds, webhooks, customer accounts, subscriptions, order records, administrative controls, and reliable handling of failed or delayed payments.
ZAXON develops payment workflows around the selected provider and the product requirements. The work can focus on integrating an existing provider or building the surrounding application logic needed to operate payments safely and clearly.
What We Build
- Payment provider integration, checkout flows, payment status handling, and webhooks.
- Orders, invoices, transaction records, balances, subscriptions, and administrative views.
- Customer account flows for payments, billing history, and service access.
- Error handling, duplicate-event protection, validation, notifications, and reporting workflows.
Development Process
- Payment mapping: Define products, prices, payment states, provider events, refunds, and business rules.
- Integration development: Connect the provider, application backend, database, webhooks, and administration.
- Testing and launch: Test successful and failed payments, duplicate events, refunds, callbacks, and account state changes.
Frequently Asked Questions
- Can you integrate an existing payment provider?
Yes. Payment providers can be integrated through their supported APIs, hosted checkout flows, webhooks, or SDKs. - Can payment systems support subscriptions?
Yes. Subscription billing can be included when the selected provider supports the required billing model.
