Thank you for the info.
I would certainly look at the invoice side of things, and even our cash register tool which could help simplify this for you.
Assuming you have no VAT to account for however, your current situation should be fine with tagging directly to the nominals.
You could certainly do this. If you’re tagging straight to the nominal codes, you are given the option to split a transaction if you have a Power User Subscription, otherwise you would need to manually split it (create 2 to replace the 1).
