Mysterious Invoice of $0 Generated and Due Same Day

[risrik]

I had a mysterious invoice created. A client was sent a first overdue notice today (July 28 ) for an invoice that was generated on July 26th and due the same day. The amount is $0! This invoice was not created by me and no associated email was created or sent to them. I didn't catch it until the overdue notice went out today (two days after it was 'due').

 

Why did WHMCS create an invoice of $0 due the same day when the client is in good standing and not due again until the 14th? It appears this is the only client that had a $0 invoice generated with no email. I did upgrade WHMCS from 3.8 to 4.2 on Monday morning so could this be the reason? A possible blip? Has this happened before?

Sounds like the invoice might be paid by credit on the client's account? Check the Credit line of the invoice.

 

Or if it's for $0 and has no line items then that would indicate it was an admin user who clicked Create Invoice but never followed through with the process thus leaving it empty.

There were no line items. It was a blank invoice. Since I am the only admin, and did not create any invoices because I hadn't gone in to the admin for the past few days, it's perplexing! I guess this was just a weird occurrence.

i see this every now and then, rarely when a new order is placed. i mean they don't come alone.

i don't know what generates it, maybe an incomplete order or so. the invoice has no items on it and the amount is zero.
