Landed Cost vs Invoice Cost: Why Your Supplier Price Isn't Your Real Cost

The Most Expensive Mistake in Importing

Whether you're importing to the UK, the US, the EU, or Australia, this mistake is universal. Every importer has a supplier invoice. It shows the product, quantity, unit price, and total. It's a clean, simple number. And it's almost certainly not your real cost.

The difference between what your supplier charges you (invoice cost) and what it actually costs to get that product onto your shelf (landed cost) is where most importing businesses either thrive or slowly bleed money without realising it.

This article explains both terms clearly, shows you exactly how they differ with real product examples, and explains why pricing on invoice cost alone is one of the fastest ways to kill your margins.

Invoice Cost: What It Is

Your invoice cost (also called supplier cost or purchase price) is the amount your supplier charges you for the goods. It's the number on the commercial invoice — the document that accompanies your shipment and is used for customs declarations.

Depending on the Incoterm you've agreed with your supplier, the invoice cost may or may not include certain logistics charges:

• EXW (Ex Works) — the invoice covers only the product at the supplier's premises. You pay for everything else.
• FOB (Free On Board) — the invoice covers the product plus local transport and export clearance up to the port of origin. The supplier gets goods onto the ship.
• CIF (Cost, Insurance, Freight) — the invoice includes the product, freight to destination port, and basic insurance.
• DDP (Delivered Duty Paid) — the invoice covers everything, including import duties and delivery to your door.

Most importers buy on FOB terms. This means the invoice cost covers the product and getting it to the departure port, but nothing beyond that.

Landed Cost: What It Is

Your landed cost is the total cost of acquiring a product, from factory to warehouse. It includes the invoice cost plus every additional expense:

• International freight (sea, air, or rail)
• Cargo insurance
• Customs duties
• Import VAT (or GST/sales tax)
• Customs brokerage fees
• Port handling and terminal charges
• Local delivery to your warehouse
• Inspection, testing, and compliance costs
• Banking and currency conversion fees

Landed cost is the true number you should use for all pricing and profitability calculations.

Side-by-Side Comparison

The Gap in Practice: Three Product Examples

Let's look at three real product categories to see how the gap between invoice cost and landed cost varies. All examples assume FOB terms, sea freight to the UK, and standard import conditions.

Example 1: LED Desk Lamp (Low Duty)

With a low duty rate of 2.7%, the gap is still over 35%. Most of this comes from import VAT (which is reclaimable but still a cash flow cost) and freight.

Example 2: Cotton T-Shirts (Medium Duty)

Clothing carries significantly higher duty rates. The landed cost is nearly 62% above the invoice cost. An importer who priced based on the $2.60 supplier cost would lose money on almost any sales channel after platform fees and overheads.

Example 3: Ceramic Tableware (High Duty)

For low-value, heavy products like ceramics, the gap is enormous. Freight costs represent a larger proportion of the product value, and the duty rate is steep. The landed cost is nearly double the invoice cost.

Why This Gap Matters for Your Business

1. Pricing Accuracy

If you set your selling price based on invoice cost, you're building your pricing on a foundation that's 30-80% too low. Every unit you sell generates less profit than you think — or generates a loss.

Consider the t-shirt example: if you thought your cost was $2.60 and priced at $8.99 (thinking you had a 71% margin), your actual margin on a landed cost of $4.20 is only 53%. On Amazon with a 15% referral fee ($1.35), your real profit drops to $3.44 per unit — not the $5.04 you expected.

2. Supplier Comparison

When comparing two suppliers, invoice cost alone can be misleading. Supplier A quotes $3.75 FOB Shanghai, and Supplier B quotes $4.25 FOB Ho Chi Minh City. Supplier A looks cheaper — but Vietnam may have preferential duty rates under trade agreements (such as CPTPP for the UK) that China doesn't have. After duty, Supplier B might actually be cheaper on a landed cost basis.

Always compare suppliers on landed cost, not invoice cost.

3. Product Viability

Some products look profitable at the invoice cost stage but become unviable once you add all the import costs. This is especially true for:

• Heavy, bulky, low-value products — freight costs eat into margins
• High-duty product categories — clothing, footwear, some food products
• Products requiring certification — CE/UKCA testing can cost thousands upfront

Running a landed cost calculation before placing your first order is essential due diligence.

4. Cash Flow Planning

Even if import VAT is reclaimable, you need the cash to pay it upfront. On a $25,000 shipment, that's $5,000+ in VAT that you won't recover for weeks or months (unless you use schemes like the UK's Postponed VAT Accounting). If you planned your cash flow on invoice cost alone, you may not have enough to fund the shipment.

How Incoterms Change What Appears on Your Invoice

The Incoterm you agree with your supplier directly affects the gap between invoice and landed cost:

• EXW — maximum gap. The invoice covers only the product at the factory. You pay for everything from collection onwards.
• FOB — large gap. The invoice covers the product and getting it to the port. You pay for ocean freight, duty, VAT, delivery, and everything at the UK end.
• CIF — moderate gap. Freight and insurance are on the invoice, but duty, VAT, brokerage, and local delivery are not.
• DDP — minimal or no gap. The supplier handles everything and the invoice theoretically covers all costs. However, DDP invoices often lack transparency about the cost breakdown.

Most experienced importers prefer FOB because it gives them control over freight and customs while keeping the supplier responsible for export logistics. But it also means the gap between invoice cost and landed cost is significant and must be calculated carefully.

How to Bridge the Gap

1. Always calculate landed cost before ordering — use the Import Calculator to get a quick, accurate estimate
2. Build a landed cost spreadsheet — track every cost element for each shipment so you can refine your estimates over time
3. Review after every shipment — compare your estimated landed cost to the actual cost once all invoices are in
4. Factor in currency risk — if you pay suppliers in one currency but sell in another, exchange rate movements can widen the gap
5. Negotiate on total cost, not just unit price — a slightly more expensive supplier with lower duty rates or better logistics terms might have a lower landed cost

Key Takeaways: Landed Cost vs Invoice Cost

Your supplier's invoice is a starting point, not the finish line. The gap between invoice cost and landed cost typically ranges from 25% to 80% depending on the product category, duty rates, shipping method, and order size.

Every pricing decision, every product sourcing evaluation, and every profitability analysis should start with landed cost — not invoice cost. The importers who understand this build sustainable, profitable businesses. The ones who don't eventually wonder where all their margin went.
