For grocery and convenience stores
Price thin-margin items without guessing
With margins this thin, spoilage and theft decide whether an item earns or loses. Price each product with them counted.
Quick answer: how should grocery and convenience stores price a product?
Add every cost, then the fees that take a share of the price, then choose your margin. For fresh fruit pack that works out at $3.36, leaving $0.94 profit. Skip a cost and the profit shrinks without you noticing.
Check your best seller in two minutes
Take the product you sell most. If its price was set by adding a mark-up to the wholesale price and you have never counted spoilage and theft allowance or promotion and multi-buy allowance, card fees and monthly costs, it may earn less than you think. Some items may even lose money. You will not see it in your till, only in the end-of-month result.
The mark-up trap, worked through
Marking up only the wholesale price by 28% gives a price of $2.43. After the other costs and the fees taken from that price, the sale leaves $0.12, not the $0.94 you planned. The same costs priced properly give $3.36.

Questions grocery and convenience stores ask about pricing
How do I price fresh fruit pack?
Add every cost (wholesale price, inbound delivery, card terminal fee, spoilage and theft allowance), then choose the profit margin you want. With these example costs and a 28% margin, fresh fruit pack should sell for $3.36, which leaves $0.94 profit on a total cost of $2.42. Your own costs will differ, so enter yours in the calculator.
What is the formula for a selling price that keeps your margin?
Price = fixed costs divided by (1 minus the percentage fees minus your margin). Here the fixed costs are $2.05, the percentage fees are 10.9% of the price and the margin is 28%. Percentage fees must be taken from the selling price, not from the cost, which is why a simple mark-up on cost usually leaves less profit than planned.
What costs do grocery and convenience stores often forget?
The easiest to miss are spoilage and theft allowance, promotion and multi-buy allowance, expiry write-off allowance, your own time, and monthly costs such as rent, staff wages, fridge and freezer power. Each one is a row in the Grocery / convenience preset, so you only fill in the amounts.
How do I know if a product is losing money?
Compare the selling price with the total cost, including the share of the price taken by fees. If the price is lower than that total, the product loses money. Catalog check does this for a whole product export and marks every item that loses money or has a thin margin.
Can I round to .99?
Yes. Choose a rounding rule in Settings. It only rounds up, so profit is never lowered.
Can I price many items at once?
Catalog check reads a CSV and shows which products lose money.
