Pos Profile accounting

i want to ask about
pos profile in Write Off Account
which account sales or cost of good sold ?

HI. Neither of the two. Write Off account is to send a certain amount to loss. It is if a part of a sale invoice´ll not be paid.
For example: if a sale invoice is for $9.15 and the customer pays $10 but you don’t have $0.85 in change to return. If you only have a $1 bill.
You can Write Off 0.15 so the amount due on the sale invoice will be $9 and $1 is returned to the customer.
