Site indent to purchase order: the two documents that stop material leaking
Material is usually the largest line on a project and the least documented. The site asks on the phone, the office buys, the bill arrives weeks later, and nobody can now say who asked for what or whether it was delivered. Two short documents fix most of it.
Why these are two documents and not one
An indent is a request from the site. A purchase order is a commitment to a vendor. They are written by different people, at different times, for different purposes, and collapsing them into one step is what removes the control.
When the site phones the office and the office phones the vendor, the only record is a delivery note from a supplier, which proves what arrived and nothing about what was asked for, by whom, or whether anyone approved it. The indent is what makes the request accountable; the purchase order is what makes the price accountable.
- IndentMaterial · qty · date needed
What the site needs, in what quantity, by when.
- ApprovalApproved by · date
Who authorised the spend, before anybody calls a supplier.
- Vendor & rateVendor · rate · unit
The quoted rate the order is placed at, frozen as a snapshot.
- Delivery termsSite · schedule
Where, by when, and who pays freight and unloading.
- Received quantityGRN · short / excess
What actually arrived, which is rarely what was ordered.
- Bill matchingPO ↔ GRN ↔ Bill
Supplier bill reconciled against the PO and the GRN before payment.
What a site indent has to record
An indent is short by design. If it takes more than two minutes to raise, it will be replaced by a phone call.
- Site and date — which project is consuming this
- Material, specification and grade — not "cement" but the grade; not "steel" but the diameter
- Quantity and unit — with the unit written, because bags and tonnes have been confused before
- Required by date — the difference between an urgent purchase and a planned one
- Raised by — the person accountable for the request
- Approved by — the person accountable for the spend
- Purpose or work item — what it is being consumed on
The indent that was never approved
Approval is the field most often skipped, and it is the one the whole document exists for. An indent raised and acted on without approval is a phone call with extra typing.
The approval threshold does not have to be high. Many builders approve everything above a small value and let routine consumables pass on the site engineer’s authority alone. What matters is that the threshold is stated, so that nobody has to decide case by case whether this particular request needed a signature.
What a purchase order has to record
The purchase order is where the commercial terms live, and where a later dispute with a vendor will be settled.
| Field | Why it is there |
|---|---|
| PO number and date | The reference every later document quotes |
| Vendor name, address, GSTIN | Who is being ordered from, and their tax identity |
| Delivery address and site | Where it goes, and which project it belongs to |
| Item, specification, brand | What was ordered, in terms the vendor cannot reinterpret |
| Quantity and unit | The basis for checking short supply |
| Rate and basis | Per unit, and whether it includes delivery |
| Taxes | Whether the rate is inclusive or exclusive |
| Delivery schedule | Full or staggered, and by when |
| Payment terms | Advance, on delivery, or credit period |
| Authorised by | Who committed the company to this |
Brand and specification are a commercial term, not a detail
A purchase order that says "cement, 200 bags" invites the vendor to supply whatever is cheapest to them at that moment. The rate was quoted against something; if the order does not record what, the comparison that justified the rate cannot be reconstructed.
Record the brand where brand was quoted, and the specification where the material has grades — cement grade, steel diameter and grade, tile size and finish, pipe class. A specification written on the order is also the basis on which material can be rejected at the gate, which is the only moment rejection is easy.
Receiving is where the loop closes
An order with no record of receipt proves nothing. The delivery should be checked against the order, not against the vendor’s own challan, and the quantity actually received written down — because short supply is common, usually small, and almost never disputed after the fact.
Three quantities should be comparable at any time: ordered, received, and billed. When the bill arrives, it is checked against what was received, not against what was ordered. A vendor billing the ordered quantity for a short delivery is the single most common way material cost inflates quietly, and it is invisible unless those three numbers sit in the same place.
Where the cost actually leaks
Not usually theft. Four ordinary mechanisms account for most of it, and all four are documentation failures rather than integrity failures.
- Material ordered for one site, delivered to another, charged to the first
- Short supply accepted at the gate and billed in full
- Rate agreed verbally, billed higher, paid because the bill looks routine
- Bulk purchase across three projects charged entirely to whichever site was named on the bill
Common questions
What is a material indent in construction?
A request raised by the site for material it needs, recording what, how much, by when, who asked and who approved. It is the document that makes a material request accountable before any money is committed to a vendor.
Is an indent the same as a purchase order?
No. An indent is an internal request from site to office. A purchase order is an external commitment from the company to a vendor, carrying rate, tax, delivery and payment terms. One leads to the other, but they record different things and are approved by different people.
Should the purchase order mention brand?
Where brand was quoted, yes. A rate was agreed against a specific material; an order that does not record which one cannot be checked against the quotation, and leaves the vendor free to supply an alternative. Specification matters for the same reason — grade, diameter, class.
Why compare ordered, received and billed quantities?
Because short supply is common and rarely disputed later. Checking the bill against what was received rather than what was ordered is the control that catches it, and it only works if all three quantities are recorded against the same order.
