If you need to edit data sales then you can refund your wrong receipts and again sale with right data.

and before you can set the date which you need on your device.

For example, you sale item1 for 20$ at Dec, 20 2016 and you discover that price supposed to be a $19.90

1st, you need go to setting on your device and change the current date to Dec, 20 2016/

2nd, you need to refund your receipt

3d, you need make sale with right price

4th, please, do not foget back the current date.

that's it!
