How to fix dates on an invoice so they are chronological?

Hi there, @skkoakland-gmail.

Are you referring to the dates on the invoice list? If so, the setup for its dates is already in chronological order. You can either set its arrangement from latest to oldest transactions or vice versa.

If you're referring to reorganizing the dates sequence when creating the invoice, you can simply adjust the Net Terms setup. Just click the Terms drop-down arrow, then choose a term on the Invoice page.

If this is not the case, feel free to add more details about your concern in this thread. This way, I can provide you the right steps to resolve the issue.

Additionally, there are several financial reports you can run to track your sales income in QuickBooks. They will show you helpful insights on the things you buy and sell, and the status of your inventory. 

Let me know how else I can help you with QuickBooks by adding a comment below. I'm more than happy to lend a helping hand. Keep safe!

what if they have to enter a transaction in the middle of 2 dates?
