The current solution of having to find an invoice to return goods from when issuing a credit note that is related to beer being returned to the brewery (which brings along a reverse of excise tax) is cumbersome. If you are new to Breww and there is no invoice to return goods from (because the beer was sold prior to using Breww), there is no good solution to “back out” that excise tax and increase the inventory. Even if you are returning goods and there is an invoice you can find, it takes alot of work to reach the final goal of issuing credit, incrementing inventory and adjusting excise tax owed. The interface should make this much easier than how it operates today. Maybe provide you with sales invoices previously issued for that product and customer without having to hunt for one and in a situation where it cannot find one, it should still allow you to return the goods to inventory and reverse the excise tax. Because in the end, I don’t really care that the returned goods match up to a sales invoice, I just care that my inventory is correct and that my excise taxes are correct.
