Here is essentially what happens between ShopKeep and QBO upon register closing. Two entries are made, one a Sales Receipt and the other a Journal Entry.
The Sale's Receipt is fairly straight forward, includes all products and services sold and their totals are batches up. This will include returns and discounts but does not include items such as Sales Tax. The only option you have is which to have it 'Deposit To' by default I think it's 'Inventory'.
While I probably would prefer everything such as Sales Tax and tenders received be included in the automated Sales receipt. For whatever reason that's not the route ShopKeep went with and they instead also create a Journal Entry: Tenders. The entries in here lead with your credits of the Sale's Receipt so Line 1 would be 'Inventory'(or whatever you map it to) and have your daily sales amount summarized. This is followed by another Credit of Sales Tax. The next series of lines are all the Debits pertaining to monies collected. The only I'm looking at has 4 lines for various credit cards, one for cash and one for a Venmo payment. Obviously the Debits and Credits zero out. The last item on the JE is the memo where it shows who opened the register and the amount it opened with. Then who closed the register and the closing amount and if there are any Over/Short amounts pertaining to the register.
With the idea of ensuring clean and organized books, what are some suggestions on handling these two entries?
