# Import business accounting COGS landed cost: the basics every importer should know

Import business accounting COGS landed cost questions come up the moment an importer realizes the supplier's unit price is only part of what each item truly costs. This guide explains how landed cost feeds into COGS, how inventory accounting works for imported goods, and where the numbers usually go wrong.

Most new importers track the wrong number. They know the factory price to the cent and have only a rough guess at what the goods cost by the time they sit in the warehouse. That guess infects everything downstream: pricing, margins, tax filings, and decisions about which products to reorder. It is the exact problem that import business accounting COGS landed cost discipline is meant to solve. Getting import business accounting COGS landed cost right is not advanced finance. It is the bookkeeping that makes the rest of the business legible.

What does import business accounting COGS landed cost actually mean in practice?

Three terms, three different jobs. Landed cost is what one unit truly cost you by the time it is sitting in your warehouse ready to sell: the supplier price plus freight, insurance, duties, brokerage fees, and any other charges tied to getting that shipment home. COGS, cost of goods sold, is the accounting figure for what the units you actually sold cost you, pulled out of inventory when the sale happens. Inventory is the holding pen in between: goods you have paid for (or owe for) but have not sold yet.

The chain runs in one direction. Landed cost determines the value sitting in inventory. When units sell, that value moves from inventory to COGS on the profit and loss statement. Closing the gap between supplier price and true unit cost is the entire point of import business accounting COGS landed cost practice. Sell a unit for 40 that landed at 22 and your gross profit on that sale is 18, before operating expenses. The reason import business accounting COGS landed cost trips people up is that the landed part has five or six moving pieces, and most importers only record one of them.

A useful habit: never enter a shipment into your books at the supplier price alone. The moment goods arrive, attach every cost of that shipment to the units in it. Your future self, doing taxes or deciding whether a product is worth reordering, will be working from true numbers instead of optimistic ones. That is import business accounting COGS landed cost hygiene at its simplest: full cost in, true numbers out.

How do you calculate landed cost per unit?

The formula is simple; gathering the inputs is the work. Add up the supplier invoice total, international freight, cargo insurance, import duties and taxes, customs brokerage and clearance fees, port and handling charges, and domestic freight to your warehouse. Divide that total by the number of sellable units received. That quotient is your landed cost per unit, and it is the number that should enter inventory in your books. This is the core calculation in import business accounting COGS landed cost work, and it repays careful attention.

Two details complicate this in real shipments. First, shared costs need a sensible allocation. If one container holds three products, the freight and duty do not split evenly by unit count when the products differ in value or weight. Allocate freight by weight or volume and duties by dutiable value, and write down the method you chose so you apply it consistently. Second, quantities change between order and receipt. Short shipments, damaged units, and quality rejects mean the units you can sell are fewer than the units you paid freight on. Landed cost per sellable unit goes up when ten units out of a thousand arrive broken. Import business accounting COGS landed cost rules are unforgiving on this point: the per-unit figure must reflect sellable units, not ordered units. Record the loss against the shipment so the per-unit cost reflects reality.

Keep a landed cost worksheet for every shipment: one page (or one spreadsheet tab) listing each cost component, the allocation method, the unit count received, and the final per-unit figure. When your accountant asks how inventory was valued at year end, that stack of worksheets is the answer. Import business accounting COGS landed cost accuracy lives or dies on whether these worksheets exist.

Why does COGS go wrong for importers so often?

The most common error is timing, and most import business accounting COGS landed cost mistakes fall into four buckets, starting with this one. Goods paid for in March, shipped in April, and received in May belong in inventory when received, not when paid. Importers on cash-basis thinking record the supplier payment as an expense immediately, which understates profit in the paying month and overstates it in the selling months. Even if your books are cash basis for tax purposes in your jurisdiction, you need an accrual-style view of inventory to know your real margins.

The second error is the partial-cost problem described above: inventory entered at supplier price, with freight and duty expensed separately as period costs. This understates inventory, overstates COGS timing mismatches, and makes every product look more profitable than it is. If freight and duty are material, and for importers they always are, they belong in the unit cost. Leaving them out is the single most common import business accounting COGS landed cost mistake, and the fix is purely procedural.

The third error is currency. You agree a price in one currency, pay the deposit at one exchange rate, and pay the balance at another. Which rate values the inventory? The consistent answer is to record the payable at the rate on the transaction date and recognize exchange differences separately as they occur, rather than letting them silently inflate or deflate unit costs. Pick a policy with your accountant, document it, and do not change it mid-year. Currency treatment is one of those import business accounting COGS landed cost details that looks minor until a volatile year makes it material.

The fourth is the deposit limbo. A 30 percent deposit to a factory is not inventory and not an expense. It is a prepaid asset, money you have sent but hold no goods for yet. It becomes inventory cost when the goods ship or arrive, depending on when title transfers under your shipping terms. Importers who expense deposits immediately create phantom losses in the order month and phantom profits later.

Which inventory valuation method fits an import business?

You need a rule for which units are considered sold when identical units from different shipments sit in the same warehouse at different landed costs. This "which units sold" question sits at the heart of import business accounting COGS landed cost method. The two methods most importers use are FIFO and weighted average.

Under FIFO, first in, first out, the oldest units are treated as sold first. If your March shipment landed at 20 per unit and your June shipment at 24, a July sale pulls COGS at 20 until the March units are exhausted. In periods of rising costs, FIFO shows higher gross profit and higher ending inventory values. It also matches the physical reality for goods where you actually rotate stock.

Under weighted average, every sale pulls COGS at the average cost of all units on hand. The March and June shipments blend into one average, recalculated with each new receipt. This smooths out the spikes from any single expensive shipment and is simpler to operate when products are truly interchangeable and stock rotation is not strict.

Specific identification, tracking each unit to its actual shipment cost, is precise but only practical when units are distinguishable, such as serialized equipment. Most importers working through their import business accounting COGS landed cost choices should pick between FIFO and weighted average, confirm the choice is acceptable in their jurisdiction, and apply it consistently. Switching methods year to year to flatter the numbers is the kind of thing auditors notice.

How should you set up your books for import accounting?

Start with the chart of accounts. You need separate accounts for inventory (an asset), COGS, freight-in, import duties, and foreign exchange gains and losses at minimum. Lumping freight and duty into general expenses is the bookkeeping version of not keeping landed cost worksheets: the information exists but you cannot use it. That separation of accounts is what makes import business accounting COGS landed cost reporting possible at all.

Next, decide who does what. The person receiving goods should confirm quantities and condition against the packing list, because the unit count they report drives the landed cost math. The person paying suppliers should attach every cost invoice, freight, insurance, brokerage, to the shipment file. If one person does both, add a monthly review where someone else spot-checks two or three shipments end to end. Import business accounting COGS landed cost errors are usually data entry problems, not accounting theory problems, and a second pair of eyes catches most of them.

Then close the loop monthly. Reconcile inventory on the books to a physical or system count, investigate the variance, and make sure every shipment received that month has a landed cost worksheet. A monthly close that takes half a day saves a year-end reconstruction that takes weeks. Your accountant can then do tax work from clean numbers instead of spending billable hours rebuilding your year, which is the practical payoff of import business accounting COGS landed cost discipline.

One practical note on software: any accounting package that supports inventory items with average or FIFO costing and multi-currency payables will do. The tool matters less than the discipline of entering every shipment cost against the shipment. Importers sometimes hire a sourcing agent to manage purchasing and logistics; if you do, make sure the agent provides itemized cost breakdowns per shipment. Sourcing Ally, for instance, gives clients documented supplier, inspection, and shipment costs, which feed directly into landed cost worksheets instead of arriving as one lump sum.

Key takeaways

  • Landed cost is the full per-unit cost in your warehouse; it flows into inventory, then into COGS when units sell.
  • Build a landed cost worksheet for every shipment, allocating shared freight and duty sensibly and adjusting for damaged or short units.
  • Do not expense supplier deposits; they are prepaid assets until the goods arrive.
  • Handle currency consistently: record payables at transaction-date rates and keep exchange differences separate from unit costs.
  • Choose FIFO or weighted average for inventory valuation, confirm it locally, and stick with it.
  • Reconcile inventory monthly so year-end tax work starts from clean numbers.

Frequently asked questions

### Should freight and import duty be part of COGS or treated as separate expenses?

They belong in the unit cost, which means they sit in inventory first and reach COGS when the units sell. Getting this classification right is fundamental to import business accounting COGS landed cost accuracy. Expensing them immediately understates inventory and distorts margins. Only trivial amounts that would not change any decision can reasonably be expensed directly, and even then consistency matters more than the shortcut.

### How do I handle a shipment where the supplier short-shipped part of the order?

Reduce the received unit count and recalculate landed cost per sellable unit on what actually arrived. If the supplier credits or refunds the missing units later, record that against the shipment. Do not spread the missing units' cost across future shipments; each shipment's worksheet should stand on its own.

### What exchange rate should I use for inventory bought in a foreign currency?

Record the purchase at the rate in effect on the transaction date, and recognize any difference between that and the rate when you actually pay as a foreign exchange gain or loss, separate from the unit cost. Confirm the exact treatment with your accountant, since tax rules on foreign exchange differ by jurisdiction.

### Does it matter whether I use FIFO or weighted average?

Yes, mainly for how costs flow through in rising or falling markets and for the ending inventory value on your balance sheet. FIFO tracks older costs into COGS first; weighted average blends them. Either is defensible for most importers. What is not defensible is switching back and forth or using no method at all.

### How detailed should my inventory records be for tax purposes?

Detailed enough that an auditor can trace any COGS figure back through the inventory records to specific shipments and their landed cost worksheets. Keep the worksheets, the supplier invoices, freight and duty receipts, and the receiving records together per shipment. That per-shipment file is the physical form of import business accounting COGS landed cost record keeping. Retention rules vary by country, so confirm the current official requirements rather than guessing.

Conclusion

Import business accounting COGS landed cost discipline comes down to three habits: worksheet every shipment, value inventory at full landed cost, and reconcile monthly. Importers who do this know their true margins, file taxes from clean numbers, and can tell at a glance which products deserve a reorder and which were never as profitable as they looked. The supplier's unit price is where the story starts. Landed cost is where the truth is, and import business accounting COGS landed cost discipline is how you keep the two from drifting apart.
