L, B, D and nos against the BOQ item, with deductions, photos and the place. It syncs when the site has network.
Each item shows executed against BOQ, with alerts at 80% and 100%, so extra items get approved before they are built.
Retention, advances, secured advance, cess, TDS and GST TDS are set once per work order and applied the same way on every bill.
When the client certifies, the amount reaches Tally Prime as a receivable and the GST TDS credit is matched on the portal.
