Loose goods, packs and cartons, barcodes and stock counts: how kiryana and general stores in Pakistan can keep their shelves and their records in agreement.
A bag of sugar does not cost what the mandi bill says. The truck, the loaders and the toll are part of its cost, and if they are not counted, every kilo looks more profitable than it is. What landed cost is, two ways to share it, and how MartPOS adds it to a purchase.
Half a kilo of daal, a pao of haldi, Rs 100 of sugar, a whole bag of atta. How a cashier bills loose goods by weight or by the rupee in MartPOS, why Rs 50 of sugar can come to Rs 50.08, and what the till checks on every line.
Packed milk, yoghurt, bread and biscuits go off; soap and matches do not. How a grocery or general store can keep track of dates only where they matter, find what to move before it expires, and deal with what has, with the way MartPOS does it and its limits.
Loose daal, rice and spices come without a maker's barcode, and so do the 1 kg packets you fill yourself. Two ways to make them scan at the till in MartPOS, which to use when, and why you should never make up an EAN-13 number.
Sugar by the kilo and by the 50 kg bag, oil by the bottle and by the carton, eggs by the dozen and by the tray. How to set up units and packs so that every sale, whatever the size, comes out of one stock figure that stays right.
A general store rarely gets a day off to count. How to count a shelf, a category or the godown while the till keeps selling, weigh loose goods, and post only the real differences, with a routine that keeps the count small enough to finish.
The last digit of every EAN-13, UPC-A and EAN-8 barcode is worked out from the others. Here is how that check digit is calculated, with worked examples, what it catches, and why MartPOS refuses a wrong barcode instead of guessing.
