Work out the cost of one piece
Cost per piece = what you paid for the carton ÷ pieces in the carton. If a carton of 24 cost ₦12,000, each piece cost ₦500.
Price both so each makes money
Single pieces usually sell at a higher price per piece than the carton, because they take more handling. Check that the carton price is still above its cost after any discount.
Keep stock in pieces
If you count stock in pieces, a carton sale takes off 24 and a single sale takes off 1, and your stock count is always right.
Doing it in Zorvya
- Add the item with its single-piece price.
- Add a pack (carton, box, tray) with how many pieces are inside and its own price.
- At the till, choose the carton or a piece; stock is taken off in pieces.
