If you need to change the customer attached to a sale, it is very easy to do so.
Keep in mind that changing a customer on a sale does not update their account with rewards or credit. These numbers are only created when the customer is present at the POS.
If you want to also update a customer's rewards, you must do so from their account.
To update the customer attached to an existing sale:
Navigate to Reports > Sales Detail Report
Find the sale you would like to fix. You can narrow down your options using a date picker if necessary.
Once you find the sale you're looking for, click the gray edit button the right.
From there you can add or update the customer attached to the sale.
Click Save.
