Why a material's invoice price is not what it costs you, and how to add freight, duties, and handling to get the landed cost your COGS is really built on.

After this you can take one key material and cost it at what it truly took to land on your shelf — not the price on the invoice, which almost always reads low. Get this one number right and every recipe that uses the material inherits an honest cost instead of an optimistic one.
The invoice says a 50-pound bag of flour is $18. That is what your supplier charged for the flour. It is not what the flour cost you, because the flour did not appear on your shelf on its own. A truck brought it. Someone unloaded it and put it away. If it crossed a border, customs took a cut. Every one of those is part of what that bag really cost you — and none of them is on the flour invoice.
Add them up and you get the material's . Four pieces:
This is not a bookkeeping nicety. It is how the cost of inventory is defined. US accounting standards put a material's cost at the expenditures it takes to bring the article to its "existing condition and location" — on your shelf, ready to use (ASC 330). The IRS says the same in plainer words: inventory cost is the invoice price plus the transportation and other charges you pay to acquire the goods, and the uniform capitalization rules under Internal Revenue Code section 263A pull the direct and indirect costs of getting and making goods into inventory rather than expensing them (Publication 538). Freight and handling to get a material in are exactly those costs.
A tax election does not change what the flour cost
Small-business taxpayers under a gross-receipts threshold — a figure the IRS indexes to inflation, so check the current one — can elect out of the full capitalization rules for tax. That is a choice about tax bookkeeping. It does not change what the flour cost you. Whatever your tax method, the number you price off of still includes the freight and the handling, or you are pricing off a cost that is too low.
Freight rarely arrives neatly attached to one material. One truck brings flour and sugar on a single $120 freight bill. To cost each honestly, you spread that freight across what it carried — a step called allocation.
Pick a basis that reflects what drives the cost. Freight is driven mostly by weight and space, so splitting it by weight is defensible:
Flour is two-thirds of the weight, so it carries two-thirds of the freight: $120 × (2,000 ÷ 3,000) = $80. Sugar carries the other $40. The two shares add back to $120 — always check that they do.
Duties split the same way but by value, not weight, because a duty is charged as a percentage of value. Handling can go by weight, by pallet count, or by receiving time — whatever honestly reflects the work. The rule is not which basis you pick; it is that you pick one that fits the cost and that the pieces add back to the whole.
Now cost the flour end to end. The figures are made up for illustration; the shape is the point.
Landed total: $720 + $80 + $20 = $820. Across 2,000 pounds, that is $0.41 a pound, or $20.50 a bag.
You had been costing flour at $0.36, the invoice number. Its real landed cost is $0.41. That is about 14 percent more — 14 percent you were quietly leaving out of every product that uses flour.
The gap compounds through your recipes
Fourteen percent on one material sounds small. But landed cost understates every material at once — the imported cocoa, the glass jars freighted in from three states away, the flour. Roll all of them up through a recipe and the finished product's cost is off by more than any single line hints. A cost you trusted to the penny was optimistic from the first ingredient.
Landed cost is not set once. Supplier prices move, a fuel surcharge lands on the next freight bill, a tariff changes what an imported material costs to bring in. A cost sheet you built in January and never touched is telling you January's story while you sell at today's prices. So re-cost a material when its invoice price moves or its freight changes — not once a year at tax time.
Doing this by hand for one bag of flour is a five-minute exercise. Doing it for every material, splitting each freight bill, and pushing the new number into every recipe that uses the material is the kind of bookkeeping a system built for food carries for you. Bettr Manager, for one, holds each material's landed cost, not just its invoice price, and uses that landed number as the material's cost everywhere it appears in a recipe. However you keep it, the discipline is the same: the cost you price off of is the landed cost, kept current.
You now have one material costed honestly — landed, per unit, current. The next question is how to carry that number up through a recipe that uses ten of them, add the labor and overhead, and land on a defensible cost for the finished product. That roll-up is the next lesson.
