Hello, I'm new to WHMCS and I need some guidance on how to go about an issue I have. We are using WHMCS, but we're not interested in using the billing section of the system at all. We use Zoho Books instead, and we would like to keep all the invoicing in one place. There are two solutions I can think of: disable and hide anything billing-related from WHMCS synch Zoho Books and WHMCS billing As far as I understand no 1 is possible by fiddling with some settings and creating a child theme to hide all the billing related elements. No 2 seems to be a development issue - either develop a WHMCS module or an external app that updates the WHMCS billing info via the use of both APIs. Also to note that we would like to create and update the invoices in Zoho rather than the other way around. Does anyone have any ideas of what is the best way to go about this? Does someone have any real-life experience? What worked best for them? Any advice would be deeply appreciated. Warmly, Thanos
