Specifies which accounts will post GST.
The GST posting setup consists of combinations of GST business posting groups and GST product posting groups. You can set up as many combinations as you need and link various G/L accounts to each combination.
After you have done this, when you fill in a line in a general journal or purchase or sales line, the program checks the GST Posting Setup window to see which accounts to use for this particular combination of GST business posting group and GST product posting group.
