I do this often because I'm quick and a lot of tines customers change their mind about the bills they want to use after I've already pressed the button. As long as you give them their change out of what they give you, not what the POS tells you to give back, it's fine.
Let's say a customer's total is $10 and they pay you with $20, but you accidentally hit that they gave you $100. The POS is telling you to give them $90 back, but there was never a $100 bill going into the tray so if you give them the $90, it'd be short and you would be giving the customer extra money. If you give them the change out of the $20, it evens out because yeah, the tray doesn't have the $100 you entered, but you're keeping the $90 the POS is telling you to give, so the $10 is all that needs to be accounted for.
tldr; give them the correct change out of the amount they give you. use a calculator if you have to. ask your FEC/a CSS for help if a transaction ever really confuses you, better to have the customer wait a second than for your register to be short.
Basically the math always works out.
Let's say the Till started with $200 in it, and you enter $100 for a $10 order, which in reality was paid for with a $20. The till is expecting to go up to $300 from taking the $100, then down $90 for removing the customer's change, ending at $210.
In reality you have the till go up by $20 to $220, then down to $210 again when you give the change. So it ends where it expected it to end anyway.
The only way to be short or over is if you don't correct the error yourself.
What I personally do is write over the incorrect amount I received and their changed on the customer's receipt with the correct amount. This way I let them know it was my fault, and that they can acknowledge it. I also print out a copy of that receipt and leave a note on it saying "I entered the wrong amount on the POS" for whoever is doing the back office.
tldr; Always give the customer the change they should receive and let them know you entered an incorrect amount on the POS.
This is really unnecessary. Especially letting the CO person know. They won't even find out as long you give back the correct amount based on what the customer actually gave you, not what you accidentally input.
Cool, I'll continue doing it this way because it literally isn't negative in the slightest. Keep being negative.
Which part of my comment was negative though? Lol. Just letting you know you're wasting your time on something that's only going to make the CO person 2nd guess themselves when the till naturally balances.
Hey I do it for my own security, even if its unnecessary.
