We need two modules developed for the WHMCS Billing application. The module would provide API integration between the billing and automation functions of WHMCS and our service application(s). All service software (including WHMCS) have comprehensive, published APIs.
The functions we require are all available and defined as standard functions within the WHMCS Module Developers Kit with corresponding APIs (and sample code) described with the API documentation for each application.
For anyone with WHMCS module development experience, this should be a relatively simple build.
Based on successful results, additional modules may be required.
We want to move forward with this project as soon as possible and look forward to your reply.
