its still ridiculous.

i own a shop.

customer RMA PS3 so i give a receipt design A (even with a shop stamp).

so my business got bigger, i move to another shop/expand the shop/ or sell it to someone.

we are so commercialized now with a brand new team, so i change my receipt to design B.

customer with receipt A comes in, i simply say no, because we used design B now.

the heck, i can easily make money like this!

how can you change your receipt design without informing customers with receipt A that the receipt is gonna be invalid?

the least you can do is to call them and update/change the receipt.
