I'll just copy / paste from a ticket I submitted:
**
I manually added new orders (4) for one client. I then added manually one invoice per order. Then, automatically whmcs created a NEW invoice #xxx which included ALL 4 invoices unpaid, while the other 4 are still there, also unpaid. Why does whmcs do this? It's pointless, confusing and stupid.
#2
I just notice that one of the 4 invoices was already paid yesterday but not updated/marked so in the automatically created one whmcs made of the 4. This is so absurd when it comes to accounting / auditing
#3
4 invoices were included, one of them was paid while other 3 were not and the one whmcs created automatically shows ALL 4 UNPAID
WHMCS Support's Response
The reason for this behaviour is that manual invoices aren't associated with the service, WHMCS can't know these manual invoices related to the services. So it saw that these services had not been invoiced and therefore generated one.
If you didn't want WHMCS to automatically generate invoices then you'd need to move the Next Due Date forward to a date in future, and then when the client paid the manual invoices set the Next Due DAte to the correct date for the renewal invoice to be automatically generated.
My thoughts/response (yes I'm frustrated)
This is a very stupid setup and method. If someone creates the order manually and unchecks the option to automatically generate invoice, then why the hell is whmcs STILL generating the invoice later that day? That is stupid, pointless and defeats the purpose.
