Welcome to this thread. I appreciate you following the suggested workaround provided by my colleague.
Since the suggested fix did not resolve for you, try to check if you have recurring invoices pending in your account.
Once confirmed, I'd suggest you create and set an alpha-numeric invoice number as your starting point instead. QuickBooks will then make the next invoice number in sequential order. Here's how:
- Go to the Customers menu.
- Choose Create Invoices.
- Create a dummy invoice.
- In the Invoice # field, enter an alpha-numeric figure in the field box such as A1000.
- Click Save.
When you create an invoice the next time, QuickBooks will assign the correct number in an alpha-numeric sequence. Before creating a new one, make sure to first delete the dummy invoice to keep your records in order. Here’s how:
- Click Previous at the top to find the invoice.
- Choose Delete Invoice from the Edit menu.
Please let me know how it goes, @Mwheatley. We're always here to help.
