WHMCS Payment Gateway Development
Australian Checkout & Renewals
We develop and integrate WHMCS payment gateways for Australian hosting and SaaS billing—official modules where they exist, vetted third-party modules, and custom builds when required. Checkout, renewals, and reconciliation are tested against your live product rules.

Australian gateway notes
eWAY
Official WHMCS integration. Use WHMCS-supported eWAY module configuration and credentials from your eWAY account.
TODO(owner): confirm if Berisco delivered eWAY work for clients.
Pin Payments
Third-party WHMCS module. Not a WHMCS core module—typically a marketplace or vendor module with its own update cycle.
TODO(owner): confirm Berisco-built Pin modules.
Stripe
Official WHMCS integration. Includes Australian methods such as BECS direct debit when enabled in Stripe.
Custom theming and workflow automation available on request.
Afterpay / Zip
Custom module only. No official WHMCS module from WHMCS Ltd—requires custom gateway development and compliance review.
Custom development available.
PayID / BPAY
Reconciliation automation. Often manual or bank-portal led; we automate invoice matching and WHMCS status updates where data is available.
Custom automation available.

WHMCS payment gateway FAQ
Does WHMCS include Australian payment gateways out of the box?
Some gateways ship as official WHMCS integrations (for example eWAY). Others rely on third-party modules (Pin Payments) or custom development (Afterpay, Zip). We help you choose a supported path for your stack.
Can you integrate Stripe with BECS direct debit in WHMCS?
Stripe is available as an official WHMCS integration and supports Australian payment methods including BECS direct debit where enabled on your Stripe account. We configure and test flows in WHMCS checkout and billing.
What about PayID or BPAY?
PayID and BPAY are often handled outside standard card gateways. We build reconciliation automation—matching references to invoices and updating WHMCS when payments arrive.
Have you published WHMCS payment gateway modules?
We document several gateway projects on our blog, including Cash App, Square, and GoDaddy Payments modules. Other Australian gateways are scoped as custom work—TODO(owner): confirm public case list beyond blog posts.
Do you replace my existing WHMCS gateway?
We can add parallel gateways, migrate checkout settings, and regression-test renewals and admin captures before you switch traffic.
