Construction material management: GRN, stock and purchase orders

Sampraxis tracks construction material from order to use: indents from site, purchase orders, goods receipt notes (GRN) at the gate, stock by project and issues to work. Low-stock alerts warn you before a site runs short, and each accepted GRN flows into the vendor bill and the accounts. It is for contractors and builders who buy and store material at site.

Launching soon: part of Sampraxis Project Management, which opens to early-access firms first.

GRN at the site gate

Material management on most sites breaks at the gate: a lorry arrives, someone signs the delivery challan, and the office finds out at month end. In Sampraxis, the site engineer records the GRN against the purchase order on the Android app as the material is unloaded — quantity received, date and any shortfall — so the office sees the receipt the same day.

Stock by project, with low-stock alerts

Every receipt adds to the stock of that project and every issue to work takes it down. Set a minimum level for the materials that stop work when they run out — cement, steel, sand, blocks — and Sampraxis flags them as low stock on the materials screen and the dashboard before the site is left waiting.

From GRN to vendor bill to ledger

The vendor bill is checked against what was ordered and what was received, then posted with its GST. Input tax credit is recorded where the project's GST status allows it, and the vendor's balance updates in the same step. There is no second entry in an accounting package — see construction accounting.

Seeing where material goes

Material leakage shows up as a gap between what the work should have used and what was issued. When materials are linked to BOQ tasks, Sampraxis gives you the planned quantity for the work done to compare with what left the store, item by item and site by site.

Frequently asked questions

What is a GRN in construction?

A goods receipt note records what actually arrived at site against a purchase order: which material, how much, in what condition and on which date. It is the proof you check a vendor bill against.

Can site engineers record a GRN from their phone?

Yes. Site teams use the Android app to record receipts, issues and stock at the gate; the office sees them immediately.

How do low-stock alerts work?

You set a minimum stock level for a material. When stock at a project falls below it, the material is flagged as low stock on the materials screen and the dashboard.

Is stock tracked per site?

Yes. Stock is held per project, so cement at one site is not counted as available at another.

Does a GRN create an accounting entry?

An accepted GRN is the basis for the vendor bill, and the vendor bill posts the journal with its GST. See construction accounting for the full chain.
