# I made a mistake in a sale, how can I change it?

||| In Spain, sales cannot be removed or modified in the program according to the General Tax Law.

You will have to make a rectification sale (refund), I explain how to do it:

Cash box  > search sale > generate a rectification sale (from the 3 points of the sales line).

This will reset the cash register.

If you don't live in Spain you can delete the sale from Cash box  > search sale > delete sale (from the 3 points of the sales line).
