Hello,
As you mentioned the amount hitting the bank account does provide full details of the sale so we beed to enter the rest of the details as a Journal entry ( A single entry per month will do, i assume you will be able to get similar details about all orders from ezCater on monthly basis).
Steps:
1, When the deposit shows up in the bank account, categorise it to a current asset account eg : ezCater receivable
2, When you get split of all orders in the month end, record a JE as attached ( This should help you to record the income and expenses side of the sale correctly).
Hope this helps, Do let me know if you have any questions.
