Landed Cost: What Your Supplier's Price Leaves Out

The number on the price list is what the goods cost. It is not what it costs you to have them sitting on your shelf, ready to sell. The gap is usually 10–30%, and it's the difference between a product you think earns 40% and one that actually earns 22%.

What lands on top of the price

Landed cost is the supplier's price plus everything you must spend to get the item into your possession, sellable:

• Inbound freight — per shipment, occasionally per line. The one everyone knows about and most stores still leave out.
• Duty and tariffs — a percentage of declared value, varying by HS code and origin. Two similar parts from different countries can carry very different rates.
• Customs brokerage and clearance fees — mostly flat per shipment, which makes them brutal on small orders.
• Payment costs — card fees on supplier payments, wire fees, factoring or financing charges.
• Currency — the spread your bank takes, plus the exchange-rate move between order and payment. On imports this quietly moves costs several percent without a single price list changing.
• Handling and repack — labelling, splitting cases, kitting, the packaging you add.
• Storage — warehouse or 3PL fees, particularly for slow movers that sit for months.
• Shrink and returns — breakage, damaged-in-transit, warranty claims you eat. Small percentages, but real ones.

At a $14.00 retail, that's the difference between a 35.7% margin (on the price-list cost) and a 20.5% one. Same product, same day, same sales. One of those numbers is a business; the other is a hobby.

How to allocate shared costs

Freight and brokerage arrive per shipment, not per SKU, so you have to spread them. Three methods, in ascending order of effort:

1. By value. Each line takes freight in proportion to its share of the invoice value. Trivial to compute, and roughly right when items have similar density.
2. By weight or volume. Fairer when your catalog mixes heavy-and-cheap with light-and-expensive. Brake discs and cabin filters do not deserve the same freight per dollar, and value-based allocation will make one look great at the other's expense.
3. By unit. Split the freight evenly across units. Only sensible when everything in the shipment is broadly similar.

Whichever you choose, apply it consistently. Landed cost is most valuable as a comparison between products and over time; switching methods mid-year destroys the comparison and tells you nothing useful.

Where to put the number

You have two honest options, and one bad one.

Option A — landed cost in the cost field

Put the fully landed number in Shopify's cost per item. Your margins and profit reports become genuinely accurate, which is the entire point. The trade-off: the number no longer matches your supplier's invoice, so when you compare against a new price list you must remember to compare like with like — supplier price against supplier price, not against your uplifted figure.

Option B — supplier price in the cost field, uplift applied in your own analysis

Shopify's reports stay understated by your uplift percentage, but reconciling with supplier invoices is trivial and price-list diffs are clean. Workable if you actually maintain the analysis and know the size of the gap.

The bad option

Landed cost for some SKUs and supplier price for others, with no record of which is which. This is where most stores end up by accident — someone adds freight to the imported lines "to be more accurate" and nobody documents it. Six months later no one knows which costs mean what, and every product-level comparison is quietly meaningless. Pick one convention, write it down, and apply it to the whole catalog.

When landed cost isn't worth it

Precision has a price. Skip or simplify it when:

• You buy domestically, delivery is free over a threshold you always exceed, and there's no duty. The uplift is a rounding error — use payment fees only, or nothing.
• Your margins are wide and consistent. If everything runs 60%+, a 3% uplift changes no decision you'll ever make.
• You'd be trading a working weekly cost review for a landed-cost project that takes three months. Catching a supplier's 20% increase next Tuesday is worth more than a perfect allocation model next quarter.

Conversely, it matters a lot if you import, if freight is a meaningful fraction of goods value (heavy, bulky, or cheap items), if you run thin margins, or if you're deciding which lines to keep and which to drop.

The trap: landed cost drifts on its own

The reason to revisit this even when suppliers hold their prices: every component of the uplift moves independently. Freight rates, fuel surcharges, tariff schedules, exchange rates, your card processor's terms — any of them can shift your true cost by several percent while the price list stays untouched. That kind of drift produces no invoice, no announcement, and no email you can diff. It just shows up eventually as a quarter that made less money than it should have.

So set a cadence: recompute your blended uplift quarterly, and always after a freight-rate change or a serious currency move. A number you calculated once in 2024 and never revisited is arguably worse than no number at all, because you trust it.
