c# - Quickbooks .IIF file invoice -

i'm creating application can export .iif file, can imported on quickbooks invoice. got sample format of .iif invoice? can automate "item, "description", "quantity", "rate", "amount", "tax".

now, able import vendor name. , items still on list needs manually selected on quickbooks.

i'm creating application can export .iif file,

.iif files have been deprecated, , officially unsupported, 10+ years now.

they known cause corruption quickbooks data files.

do not use them.

use quickbooks sdk instead. provides xml/com interface directly quickbooks documented , reliable.
