Adding Labes to Invoice


I had a script developed to import orders into QuickBooks. Works fine, except if the Billing Address and Shipping Address have a different amount of lines. Example, Billing address uses 5 lines, one for a company name. The ship to address only has 3 lines, no company name. Same if an Apt is on one line in one address and not on the other.

I need to add the address labels (example, Address Line 1) to each of the address lines to the invoices [Print Invoice]. If possible, just on the admin side.

What to I have to do to accomplish this modifications?

Thanks for your help.
