Many times I need to adjust Settings/Invoice Settings/Counter to +1 as I got doubled Quote/Invoice numbers. I don’t actually know what causes it. Maybe leaving the invoice without saving, cloning, converting Quote to Invoice. Don’t know, but it happens. It’s a bit annoying having to check if correct number every time.
I have converted a quote to invoice and I got number 401. After it, I created new client and Invoice and again I got 401.
I don’t wan’t to play with live database too much as Invoices can not be deleted unless deleting the database entry. I hope it’s enough for you to locate the problem.
No, I’m not deleting records manually. That’s why I don’t want to create dummy invoices to track the issue. I would assume if I set the Invoice Number Counter once, then is should always add +1 to the next invoices.
This may be related to your invoice/quote number settings. If ‘Share invoice number counter’ is enabled on /settings/invoice_settings#quote_number the quote would take the next number.
You may want to try either disabling this setting or setting a quote or invoice prefix to prevent invoice numbers from conflicting.
That looks good, I’m not sure… If you can provide me with steps to replicate the problem in an empty account it’d be very helpful. Until we can replicate the problem it will be very hard to fix.
Can you check that the invoice and quote number settings on /settings/invoice_settings show the correct next numbers in the preview, maybe you need to adjust the counter?
