Why a lorry surprises the gate
The office knows a load is coming and the man at the barrier does not. What the gate needs before a vehicle arrives, and what goes wrong when it has nothing.
The challan that protects the supplier
A delivery challan is usually described from the receiving side. Written from the supplier's side it is evidence, and six months later it settles the argument.
What a delivery challan is, and what it proves
A delivery challan travels with the goods and says what left the seller's gate. It is not a bill, and on its own it is not proof that anything arrived.
What a goods receipt note is, and why it is not the challan
The GRN is your own record of what arrived, written by your side. Confuse it with the vendor's challan and you have no independent check on anything.
Three-way matching, and the case it always misses
Order, receipt, invoice. Hold the three against each other before you pay. The method is simple; the failures are all in the cases nobody enumerated.
Why measured and docketed quantities disagree
The number on the docket and the number your side measures are rarely identical. Most of the gap is ordinary physics and method. Some of it is not.
Running a site store so the numbers survive
A site store is a warehouse run in mud by one person under pressure. Four disciplines keep its numbers usable; everything else is a matter of preference.
Wastage on site: allowance, loss and arithmetic
Wastage is the difference between what you bought and what ended up in the structure. Most of it is not waste. Almost none of it is measured properly.
The bar bending schedule, and steel by weight
A BBS turns drawings into a cutting list and a weight. The arithmetic is simple and the errors are systematic, which is what makes them worth understanding.
The unit of measure is where the money leaks
A rate agreed per tonne and invoiced per quintal is a factor of ten, and it looks like an ordinary line. Units are the quietest expensive error in purchasing.
Physical stock against book stock
Stock reconciliation is a comparison between what your records claim and what is actually on the ground. The variance is not the finding. The pattern is.
Reconciling a vendor bill against what actually arrived
A vendor's invoice is a claim, not a fact. Checking it is a five-step comparison, and four of the five steps fail for reasons that are not the vendor's fault.
