Fix Value Difference on Invoice

Open The Post Store Servicings screen in BookLink, right-click on the servicing you need to fix, and choose Edit Servicing. 

On the Edit page, go to the Invoicing tab, click on the invoice, and click the Edit Item button to change ChargeQty or CreditQty to match the paper invoice. 

When everything matches between the invoice screen and invoice printout poke the Save button

NOTE: If you have to add an item, use the following to enter the ItemID (if you cannot read it on the invoice print clearly):

ItemID is the UPC which starts 086830 then has the price (14.99 = 1499, $5.99 = 0599, etc.). The last digit is calculated by BookLink, so you don't have to type it.

So for$14.99 books, type 0868301499 and press enter which BookLink will turn into 08683014997
