The invoice settings in your account settings control how A2X creates the Xero invoices when posting them to your Xero account.
By default, A2X will summarize all sales data and post the invoice with a single sales line item.
You can choose to group sales by SKU or by product type (if you have defined any).
Please Note: If you group by SKU, we will pass SKU and quantity data to Xero too, but note this requires that all your SKU's are already registered in Xero.
These settings do not automatically apply to old settlements, they are instead applied by refreshing the settlement(s).
