- Size, grade and specification
- Hardware items differ by size and grade: bolt diameter, pipe class, hinge length, lock lever count. Printing these specifications confirms what was sold and prevents returns for the wrong size being accepted without checking.
- Unit of measure
- Nails and screws are sold by kg or box, pipes by length, wire by coil and locks by piece. A correct UQC on each line keeps quantity records accurate and avoids HSN summary errors in returns.
- Contractor GSTIN and project
- Contractors and builders buy in bulk and need credit. Their GSTIN, legal name and the project or site name on the invoice let them claim input tax credit and allocate the cost to the right job.
- Site delivery address
- Bulk orders of cement, pipes and fittings go straight to building sites. The site address supports place of supply and e-way bill details and helps the driver deliver to the right location.
- Brand and batch for cement
- Cement bags carry brand and week of manufacture. Recording them helps with quality complaints and stock rotation, because older cement loses strength and contractors often ask for recent batches.
- Credit terms
- Hardware shops often run monthly accounts for contractors. Credit period and account code on the invoice support follow-up and match the bill to the running ledger.
