HELLO TEAM
FIRST THANKS FOR MAKING THIS APP TO ALL WHO IS INVOLVED IN...

SO I HAVE ONE PROBLEM RELATING TRANSPORTATION COST. I WILL GIVE YOU ONE EXAMPLE OF MY PROBLEM. WE SELL SANITARY GOODS TO THE PARTY AND TRANSPORT IT BY US. WE CHARGED TRANSPORTATION COST ON THIS BILL.
FOR EXAMPLE=
ITEM AMT IS 1000
GST RATE IS 28%
INVOICE AMT 1280
TRANSPORTATION COST 200

SO TELL ME WE NEED TO ADD GST ON TRANSPORTATION COST.
