Sales tax
Sales tax invoice software
NTN and STRN on the bill. The rate on each line. FBR when that company is ready, not before.

On the invoice
The bill prints sales tax, the seller’s NTN, and STRN when the company has one. The buyer’s number prints when you enter it.
The rate
The Pakistan default is exclusive sales tax at 18%. Inclusive means the printed price already contains the tax. A province can be set on the company.
The return
Tax sales, tax purchases, and the return use the same figures as the bills. Nothing is typed a second time.
FBR
Digital invoicing has a sandbox and a live connection. It turns on when that company’s own FBR access is ready. An empty token stays in the sandbox.
