How long does it take to switch grocery POS systems?
For a store with a clean product spreadsheet, the software setup takes an afternoon. Allow one to three weeks overall so processors, scales and staff training are ready. Messy catalogues and processor paperwork are what add time. Read the guide.
How do I calculate unit cost from a case?
Divide the case cost by the number of units in the case. A case of 24 cans that costs $23.76 has a unit cost of $0.99. If the vendor adds free goods or a deposit, adjust the case cost first. Read the guide.
What does PLU stand for?
PLU stands for price look-up. The code tells the register which produce item is on the scale or in the bag, so it can look up the price. The international standard codes are managed by the International Federation for Produce Standards (IFPS). Read the guide.
