Pretty please? Just because I discount my friends and family doesn't mean my cleaner does!
Thanks!
Have your rent as position 1 - I'm thinking it would always be at the top anyway.
Have your cleaning as position 3... it will be next in line unless you have something that says it should be position #2... see next :)
Have any/all discounts as position 2, that way it only discounts the rent and is discounted before cleaning, taxes, and/or any other surcharges are applied.
