Your spreadsheet says 40% margin.
Customs says otherwise.
Forgotten duty lines, stale FX rates, freight split evenly instead of by volume — small errors that quietly eat 5–15% of margin. LandedCost finds them before you price a single unit.
That 6.1-point gap on this shipment: $1,512 of imaginary profit, found in one import.
Three errors your spreadsheet will never flag
They’re not typos — they’re the assumptions built into every landed-cost sheet. Each one looks reasonable and each one moves your real margin by points, not decimals.
Forgotten duty lines
One HS code left off the sheet and a whole product looks more profitable than it is. Duty is calculated per product from the code, never a blended guess.
Stale FX rates
A rate pasted in January still costing you margin in June. Every supplier payment is converted at the historical rate for its actual date.
Freight split evenly
Dividing a container bill equally overcharges your small items and hides the real cost of the big ones. Freight is allocated by volume, weight or value.
From spreadsheet to audited margin in three steps
Low commitment, high curiosity. Bring the numbers you already have and see what the sheet was hiding — no rebuild, no re-keying.
Bring your numbers
Import a shipment or paste in a supplier invoice. Your existing spreadsheet works fine as the first import.
We audit every line
Duty from HS codes, FX at the payment date, freight split by the right method — each figure traced back to an invoice and a date.
