Hi there, @Creative Pictures.
I'll lay down some solutions to help you fix the random sequential number when trying to print or download an invoice and to ensure you're able to change back to the correct numbering sequence.
To begin with, I suggest reviewing your invoices or the invoice number before printing or downloading them. Once verified, you can turn on the Custom Transaction Number feature to correct the numbering sequence.
Here's how:
- Go to the Gear Icon, and select Account and Settings.
- Select the Sales menu and Edit the pencil account for Sales form content.
- Turn on the Custom transaction numbers.
- Select Save and then click Done.
Moreover, try to print and download the invoice again to verify if the print invoice number changes. Then, once you have corrected the invoice number, you can turn off the function again to avoid further changes.
I've included an article that will guide you in receiving and recording invoice payments: Record invoice payments
Please let me know if you have follow-up questions about the random sequence number or anything else QuickBooks. I'll be more than willing to answer them. Take care always.
