Sometimes errors occur and the best fix depends on payment type and the products involved.
Cash sale - Physical products only
Use Swap a bag to edit the sale.
Credit sale - Physical products only
Credit sales cannot be edited with Swap a bag, so you have two options:
Find the same product in a different sale that is a Cash sale and use Swap a bag.
Do an Inventory adjustment. If you recorded Product A and it should have been Product C, you will do a +1 adjustment to Product A and a -1 adjustment to Product B. See Inventory Adjustment
Cash Sale - Heroes and Helpers
Heroes and Helpers was recorded and should have been a product or vice versa.
Refund the Heroes and Helpers sale
Record the sale again with the correct product
If Cash to Credit was done and you are unable to refund the sale, please contact support and request to speak to a human.
Credit Sale - Heroes and Helpers
Heroes and Helpers was recorded and should have been a product
If you have the customer's card to be able to re-record it, refund it and record it again with the correct product.
If you do not have the customer's card to be able to re-record it, there is no good fix. The best suggestion is to record a future sale that should be Heroes and Helpers for the product that was missed.
Note: Partial refunds are not supported. If an errors occurred that requires a refund, the entire order needs to be refunded.
