Hello, We have a Boxbilling instance with many clients that want to migrate to WHMCS. We have a working solution, full documentation and support on the driving API, we also have a working integration in the Boxbilling software. We'll need the following to be done before we can migrate over: * Creation of a Custom Provisioning Module that works with remote API (we have documentation and working integration in Boxbilling) to handle buying app license, suspension, termination, and reprovisioning (i.e. change password, update license, etc.) * Possibility to reissue provisioning by the client and limiting the number of automatic reissues. * Migration of all clients, including their Invoices, Paypal subscriptions and tickets. * Possibility to limit number of orders per client or client groups. * Paypal module must be able to do subscriptions and cancel the subscriptions if user requests cancelation (via Billing) * Template customization, with modern (responsive) templates that will look good on all modern devices with different screens (smartphones, tablets, etc.) * No watermarking. * Admin area integration (being able to trigger license changes, app configs, etc.) so support staff can do their job. Please advise if any of the above will be possible, how much it will cost and approx. estimated time for completing the work.
