GST billing software
GST decided while the invoice is written, not afterwards
HSN, rate and place of supply come from the record itself, so every invoice is GST-correct when it is raised and your returns are a read of your data rather than a rebuild of it.

The situation
What gets in the way today
Tax worked out by hand
CGST/SGST or IGST is decided line by line, and a wrong state means a credit note later.
Returns rebuilt every month
Sales are re-keyed into a spreadsheet or a second tool before GSTR-1 can be filed.
Vendor bills don't match 2B
Input credit is claimed on hope, and mismatches surface only when someone checks.
How AVS fits
GST built into every document

- HSN or SAC held on the item and applied to every line
