Review reverse-charge purchases and advances in their own GST workpapers.
1. Choose the period
Open Reports → GST Filing and check the business, GSTIN, and period.
2. Review reverse-charge entries
Open the offered reverse-charge workspace. Compare each source document, supplier, taxable value, tax, and treatment with the actual purchase.
3. Review advances separately
Open the advances workpaper and compare the actual advance receipt, its tax treatment, and any later adjustment against a sale. Do not count the same amount twice.
4. Save the reviewed decisions
Resolve warnings and have your accountant confirm the treatment. Recheck the return after changes before approving or exporting it.
