I can help and answer any questions you may have about QuickBooks, Craggles4.

However, I have to gather some information about your concern to ensure I can provide the best solution. Are you referring to automatically assigning account numbers to the chart of accounts or a specific transaction?

While we wait for the information, you can learn more about assigning alphanumeric numbers to sales entries and your chart of accounts by reading the following articles:

• Use account numbers in your chart of accounts 
• Add custom transaction numbers to sales forms 

I'm looking forward to your reply, Craggles4. Thank you in advance, and have a great weekend.
