How to compare wholesale prices across your distributors

Every store owner suspects they’re overpaying somebody. Very few can prove it, because comparing wholesale prices across distributors is genuinely hard — not because the math is advanced, but because the numbers arrive in formats designed for the seller’s convenience, not the buyer’s. Here’s how to compare honestly, and the three traps that catch almost everyone.

Trap one: the unit of measure

Distributor A quotes a case. Distributor B quotes an "each." Distributor C quotes a case that contains inner packs. The same 20-ounce beverage might appear as a 24-count case at one supplier and a 12-count at another, and the bigger number on the invoice is not automatically the worse deal. The only honest comparison is price per selling unit — divide every quote down to the single bottle, bar, or roll you actually put on the shelf. It sounds obvious; it is also the single most common comparison error in retail buying, because doing it by hand across a few hundred SKUs is nobody’s idea of an evening.

Trap two: case-pack math and the "cheap" big case

Larger case packs usually carry a lower unit price — but not always, and the exceptions are expensive. A 36-count case that undercuts the 24-count by pennies per unit is only cheaper if you sell all 36 before the category resets or the product dates out. Unit price is the start of the comparison; unit price at the quantity you can actually sell is the real number. Slow movers bought in big cases are where margin goes to die quietly.

Trap three: list price versus effective price

The number in the catalog is the list price. What you actually pay — after the off-invoice allowance, the current promotion, your volume tier, or your buying-group pricing — is the effective price, and the two can differ by double digits. This cuts both ways: a supplier with a high list and a deep current deal may beat a supplier with a friendly list price, and a "10% off!" flyer means nothing if the discounted price still exceeds another supplier’s everyday number. Always compare the price after everything, never the price in the flyer.

A practical method

If you’re doing this manually, don’t try to compare the whole catalog. Pull your top 50 items by purchase dollars — in most stores that’s a third or more of total buying — and build one sheet: item, each supplier’s current quote, pack size, computed unit price, and any active deal. Re-check it quarterly, and every time a supplier announces a price change. Two hours of work, repeated four times a year, will find real money in almost any store.

What software changes

The manual method’s weakness isn’t effort — it’s staleness. Prices move weekly; your sheet doesn’t. This is the specific problem ordering software should solve for you: every supplier’s current price on one line, normalized per unit, with deals applied, at the moment you’re about to order. It’s what we built price comparison in StoreQueue to do, with invoice capture watching for creep between orders. However you get there, the principle is the same: never compare list prices, never compare across pack sizes without dividing down, and never assume last quarter’s cheapest supplier is still this quarter’s.
