Hi there, I am currently looking for a solution to manage one of our special services via WHMCS. These are servers that are operated with a self-developed application and can only be booked by customers for individual days. This happens months in advance. Is there an existing plug-in or a solution for WHMCS to be able to make such a booking for a certain day and to show the customer directly whether servers are still available for the desired day? There are a total of 3 servers available per day, which can be rented to different customers. The provisioning of the server would take place via an existing addon (Proxmox). Thanks in advance!
