unable to remove credits and invoices dont raise on monthly subscriptions intermittently

[Rajan Maharaj]

Hi Everyone,

I have an issue where every month I need to go in and check if there are invoices that have not been automatically raised.

In those cases I have to change the dates for next due and let the system catchup.

 

This time around I had a invoice that was not created on time and then there was a credit applied.

They had paid all their subscriptions to date and there should have been no credit. Yet WHMCS created a credit and applied it to the invoice.

I raised a ticket with WHCMS and they just closed the ticket which I have reopened. But seeing if I can get some actual help here on why this would occur and how do i fix it.

I think you should check the WHMCS cron logs first, since missed invoice generation is likely related to the cron not running correctly. For the unexpected credit, check the client’s transaction/payment history—if a payment was recorded before the invoice was generated, WHMCS may have temporarily treated it as account credit and later applied it to the invoice. Fixing the cron issue should prevent this from recurring.

You should start by checking the WHMCS cron logs for the months where the invoices were missed, since a failed or delayed cron could explain the issue. Then check the client’s transaction and credit history to see what created the unexpected credit and when it was applied.
