Works-contract GST, retention as a ledger account, and 194C.
Indian contracting has three things that break generic ERPs. Works-contract GST is not ordinary sales tax. Retention is not a discount — it is a receivable you will collect years later, and holding it as a percentage on a bill header rather than its own ledger account is why so many contractors cannot say what they are owed. And TDS under 194C applies to subcontractor and labour payments, which means the deduction has to happen where the payment happens. All three are built here, and the measurement book syncs from work actually logged on site rather than being re-typed.
