How a DTC Brand Found Its Real Landed Cost After Two Years of Guessing

This is an illustrative scenario, representative of the kind of eCommerce accounting work described below. Details are anonymized and the figures are for illustration only. Results vary by brand.

The dashboard said 62 percent gross margin. The bank account said something else entirely.

That gap is the most common unexplained problem in a growing DTC brand, and landed cost is usually where it hides. This representative case study follows a brand doing mid-seven figures that had been running on a COGS number nobody had ever rebuilt from source documents.

The Problem

The brand imported from two overseas manufacturers and sold through its own site plus one marketplace. COGS in the accounting file was the unit price on the manufacturer's invoice. That is it.

Everything else that gets a product from a factory to a warehouse was somewhere further down the income statement, coded as operating expense: ocean and air freight, duties and tariffs, customs brokerage fees, drayage, inbound handling at the 3PL, and the occasional inspection or rework charge.

The result was a gross margin line that was structurally too high and an operating expense line that absorbed costs that varied directly with units sold. Every downstream number inherited the error. Contribution margin by SKU was wrong. Ad spend targets built on that contribution margin were wrong. The decision to promote one product over another was being made on numbers that did not describe reality.

The founder's instinct had been that the marketplace channel was the problem, because that is where fees are visible. It was not the main problem.

The Approach

The work, representative of a specialist eCommerce engagement, was a rebuild rather than an adjustment.

It started with source documents: twelve months of manufacturer invoices, freight forwarder invoices, customs entry summaries, brokerage bills, and 3PL inbound charges. Nothing was estimated at this stage. The point was to see the actual total cost of goods arriving.

Then allocation rules, which is where the judgment lives. A single container carries several SKUs of different sizes and weights, so shared freight and duty have to be assigned somehow. The brand adopted a documented method, allocating ocean freight by cubic volume and duty by declared value per SKU, because duty rates differ by classification. Written rules matter more than the specific choice, because consistency is what makes period comparisons meaningful.

Next, a per-SKU landed cost build-up: unit cost, plus allocated freight, plus duty and tariff, plus brokerage and drayage, plus inbound handling, plus an inspection and defect allowance based on actual history rather than a guess.

Finally, a monthly true-up. Estimated landed costs were compared to actual customs and freight invoices as they arrived, and the difference was posted rather than ignored. Without that step, the model drifts within a quarter.

The Outcome

In this representative scenario, the real gross margin came in materially below the 62 percent the dashboard had shown, and the gap was almost entirely freight and duty that had been sitting in operating expense.

Two consequences followed. Two SKUs turned out to be reliably unprofitable at their current price, both of them bulky items where allocated freight was a large share of landed cost, and both of them products the brand had been promoting because the invoice-only margin looked fine. And the marketplace channel, the founder's suspect, was performing roughly in line with the site once landed cost was applied evenly.

The response was a repricing on the two problem SKUs and a shift in ad spend toward the products with genuine contribution margin. That changed the mix rather than the top line, and it improved cash conversion because working capital stopped funding products that did not pay for themselves.

Honesty about the limits: no cost was eliminated by measuring it correctly. The money had been going out the door the whole time. The change was in decisions, and those decisions only pay off over subsequent months. Repricing also carries real risk, because raising a price can reduce volume more than it improves margin, and that trade-off has to be tested rather than assumed. Results depend entirely on the specific product mix and freight profile, and nothing here is a predictable outcome for another brand.

The Part Most Brands Get Wrong

Landed cost is not a project. It is a maintained number.

Freight rates move. Duty and tariff rates change with policy and with classification decisions. Supplier terms change. A landed cost model built once and left alone is wrong within two quarters, which is worse than no model in one specific way: people trust it.

The brands that hold onto the benefit are the ones that keep the monthly true-up and revisit allocation rules when the freight profile changes, for example when a product moves from ocean to air to fix a stockout.

Where Specialist Help Mattered

Rebuilding landed cost requires reading customs entries and freight invoices, not just categorizing bank transactions. That is a specific skill, and a generalist bookkeeper is unlikely to have it.

ECOM CPA is a Sam's List accounting firm based in Oregon, working since 2016 with eCommerce and multi-channel sellers, and serving clients across several states including Oregon, New York, California, Delaware, Florida, and Texas. A practice that has reconciled inbound freight and duty repeatedly knows where these costs hide and which allocation methods hold up.

The realistic expectation: this is a data-gathering project that depends on the brand producing a year of source documents, and the work takes time proportional to SKU count and shipment volume. It improves accuracy and decision quality, not the underlying unit economics. Confirm scope and credentials before engaging, and review the firm's profile on Sam's List.

Frequently Asked Questions

What is landed cost and what belongs in it? Landed cost is the total cost to get a unit into your warehouse and ready to sell. It includes the manufacturer's unit price plus inbound freight, duties and tariffs, customs brokerage, drayage, inbound handling at the warehouse, and a defect or inspection allowance based on history. Leaving those out of COGS overstates gross margin.

Why does my gross margin look better than my bank account? The most common cause is COGS built from the manufacturer's invoice alone, with freight and duty coded to operating expense. Those costs vary with units sold, so they belong in COGS. Until they are moved, gross margin is structurally too high and every contribution margin and ad spend target built on it is wrong.

How do you allocate shared freight across SKUs in one container? With a documented, consistently applied rule. Allocating ocean freight by cubic volume and duty by declared value per SKU is a common approach, since duty rates vary by classification. The specific method matters less than writing it down and applying it the same way every period so comparisons mean something.

How often should landed cost be updated? Monthly, through a true-up against actual freight and customs invoices, with a review of allocation rules whenever the freight profile changes, such as switching a product from ocean to air. A model built once and left alone becomes inaccurate within a couple of quarters while still being trusted, which is the more dangerous state.
