I will build a custom whmcs payment gateway module

You will get a custom payment gateway developed and integrated into WHMCS. The payment modules are of different kinds and each is handled differently. There are redirection-based gateways, merchant API gateways and Tokenised card storage gateways.

No need to panic if you don't know the kind you need. Since each payment processor has its payment flow, You can send me documentation about your payment processor and I'll share the type you need and its implementation plan.

I'm an experienced full-stack developer with more than 7 years of experience in WHMCS customization and development. I've worked with a large number of clients on WHMCS-based projects. I've developed 30+ addon modules and payment gateways for WHMCS, so you're in capable hands for your project.

I've included some screenshots of the gateways I've developed in the project gallery to ease your mind.
