I have information about the option to show the QuickBooks invoice number in your account, Jonathan. Let's delve into the details.
In QuickBooks Online (QBO), if you've imported your invoices from Magento or other software, the ID number will automatically become the QuickBooks invoice ID number, and it will appear in the NO. column in the All Sales tab.
Please know that QuickBooks will only depend on the information set up from Magento or other software.
Additionally, if you create an invoice in your QBO account, it will follow the sequence imported from Magento.
If you want to change or set your own numbering preference, you can use the Custom transaction numbers feature, which is activated by default. If you don't want QuickBooks to automatically assign numbers to your sales forms, you can turn off this option. Here's an article for more details and guidance: Add custom transaction numbers to sales forms in QuickBooks Online.
Moreover, I've attached these articles for future reference in managing invoice payments and personalising your sales transactions in QuickBooks:
