View source for Checking the calculations on the invoice

An important step when receiving an [[invoice]] is to check the calculations made by the [[supplier]] are correct. Things to check are:

* '''Quantity x unit price''' - the total price is carried down to the sub-total and is used when calculating discounts and [[Value Added Tax (VAT)|VAT]] so any inaccuracies here will throw the entire invoice out.
* '''Trade or bulk discount''' - any discounts applied to an order (including any [[Prompt Payment Discount|prompt payment discount]] where claimed and invoice paid in time to claim).
* '''VAT''' - the tax man wants to be paid the correct amount, though note VAT calculations are rounded down (or looses any digits after the penny column.
* '''Date and terms of payment''' - the accounts department needs to know when the invoice needs to be paid by.
