Go to cashier counter and pay your purchases.

When we choose our things and go to cashier to pay the items.
Does we say "Go to cashier counter and pay your purchases."

or can we say "let's pay up?"

You pay for your purchases. Why don't you use Please pay for your purchases at the checkout. I wouldn't use Let's pay up.

purchases can use any other word to instead it?

goods? selections? ... But why specify the object: 'Please pay at the checkout'? (There isn't much chance of people paying at the checkoutfor things that they haven't selected. ;-)

PS Either say 'to replace it, do the same job...' or 'Can we use any other word instead?' (You used to be able to say '...in its stead', but that's pretty old-fashioned.)
