What did each item really cost you?

A supplier invoice says a mug costs 4.20. Add freight, duty and the broker's fee and it is closer to 5. Put the invoice in below and see the true cost per item, so your margins and your Shopify cost per item are right.

Landed cost, in plain terms

Landed cost is what an item cost you by the time it is on your shelf: the supplier's price plus its share of freight, duty, customs and broker fees. If you price from the invoice price alone, every margin report you run is too high.

By value or by quantity?

Spreading by line value gives expensive lines a bigger share, which suits duty (charged on value) and most mixed shipments. Spreading by quantity gives every unit the same share, which suits shipments of similar-sized items where freight is really about volume.

Where it goes in Shopify

Shopify keeps a cost per item on each variant and uses it for profit reports. When new stock arrives at a different landed cost, the honest number is the weighted average of what you already had and what just arrived: (old units × old cost + new units × new landed cost) ÷ total units.

Sales tax you can claim back

Leave out GST, HST, VAT or other tax you recover from the government. It is not a cost of the item. Duty and import tax you can't recover belong in landed cost.
