Hi,
we are an existing service provider (Internet, Serverhosuing, Cloud-Server, Webhosting aso...), but we would like to add whmcs as a new function to our customer.
Our customers, can activate there whmcs account with a link from our existing customerportal ( API - AddClient, with refenz number,.... ), this Customer gets an special Billing Gateway (own module/addon/gateway), which add the Billing Information after checkout, to our existing ERP-System, the customer will get one invoice with the exist contracts (ex. Internet ) and the new ones from whmcs. <-- This works!
But now, here comes my problem, how can i add a recurring billing to my gateway and set the invoice as payed, without any hands-on from our customers.
Should i realize it with a hook? our by cron? or with a new addon?
