It is important to distinguish the panel and your billing system:
However, if you want an online invoicing system for your customers, which allows your customers to order and pay for your accommodation (similar to what TNC TECH does in its customer area), you will need to set up a billing system. Several solutions exist, such as Blesta or Clientexec , which can be linked to your Panel to automate the creation/suspension/deletion of your accounts. These solutions include all the tools necessary to be able to offer your offers via your website: customer area, customer basket, invoicing when ordering, automatic reminders before due dates, payments via popular platforms such as PayPal, ticket management. support, knowledge base, automatic creation and expiration of hosting, ability to register/renew/transfer domains via multiple registrars, etc.
We invite you to consult the different solutions on the market to make your choice. Ordering and support for these billing systems will be done directly with the solution provider you have chosen.
