By default, taxomate sends settlements to QuickBooks Online as Journal Entries linked to a single deposit. We have found this to be the easiest way to get started with Amazon and QuickBooks integration. Journal Entries can be used without having to understand the various validation issues that may arise with Sales Invoices.
One thing to keep in mind is if you are using journal entries, your sales information will not show up in the dashboard of QuickBooks. However, you will still be able to properly run any report (e.g., Profit and Loss) using the imported Amazon data.
Most advanced users and accountants prefer using Sales Invoices. Sales Invoices details will show up on your dashboard and allows taxomate to add more details (e.g., invoice customers).
