Generating new invoices after payments have been made

[gmc100]

Hi,

 

I am having this problem where WHMCS is generating new invoices, some of which have already been assigned to other clients, after the payments have been made.

 

eg, invoice 22984 was paid 2/10/13 with the due date being 1/10/13. The client was then invoice today (15/10/13) an overdue notice for 22942 which belongs to another client and was overdue.

 

What in fact happened was the later invoice number 22942 was used to replicate the original invoiced items but could not be paid from the original client as it belonged to another client who has not paid. His invoiced items where different but for the same dollar amount.

 

How do I fix this as many clients got overdue invoices for payments they have already made and those invoices are attached to other clients.

No takers for this one? I dont mind paying for someone to fix the problem, I just need it fixed.

Hi,

This behaviour would suggest you deleted the original invoice and/or moved the Setup > General Settings > Invoices tab > Invoice Starting # downloads.

 

This should never be done.

 

To prevent this from happening again, you must move the Invoice Starting # upwards to a totally unique number that has never been used before in your WHMCS installation (even if the original has been deleted).
