WHCMS 8.3.1 - $0.00 USD invoice overdue

[PlotHost]

Hello,

Using WHMCS 8.3.1

Client has credit. An invoice is generated, credit is applied to the invoice, but the invoice remains unpaid. Invoice becomes overdue and client opens a support ticket.

Any idea? Never had this issue.

Thank you.

Hi @PlotHost,

This behaviour indicates an error at the time payment was applied to the invoice.

Could you please share the entries from Configuration > System Log at the time of invoice generation and payment please?

@WHMCS John

It happened again this month. 

From  what I see in the logs: the paypal subscription is processed 2 hours before the current month invoice is generated.  So the money is added as credit. When the current month invoice is generated, credit is applied, and the $0 invoice is sent to the client.

There are no errors.

Invoices fully paid by credit should trigger an "Invoice Marked Paid" entry in the System Log.

Can you please share the System Log entries at the time of invoice generation for us to review?

I don't see  "Invoice Marked Paid" entry in the System Log for the invoice.

The credit is applied, but the invoice is not marked as PAID.

For a test client - I've added credit to the account. Then I generated an invoice. I added credit to the invoice. The credit is added, invoice is $0 but it's marked as Unpaid. Like in the image from the first post. Strange ...
