Hi dreamerdad!

Thank you for sharing how the invoice number order is affected when transactions are exported from your app. Please know that we cannot control the order when there is data coming from a third-party app, so you may need to make some edits.

QuickBooks is designed to automatically assign the next number in the sequence. For example, if you use 123 on the current invoice, the next invoice will automatically be assigned 124, 125, and so on. You can change the number as you create more invoices, and the system will simply assign the next number in the sequence to the next invoice.

On the other hand, you can check our Help articles if you want to see some references for QBO.

Feel free to go back to this thread if you have other concerns about invoices. Take care and have a good one!
