Landed cost per unit, freight and duty included.

Every received purchase-order line gets its own landed cost per unit:

Units received, not ordered: the units you can sell are the units that arrived, so a short shipment spreads the order's cost over what actually landed.

The figure is recalculated in the background whenever a purchase order or one of its costs is saved, so the screen you are on never waits for it, and a save can never leave the cost stale.

A freight invoice rarely belongs to one product. CogsIQ splits each purchase-order cost across its lines by the method you choose:

• By unit count. Each unit carries the same share. The usual choice for freight, which tracks quantity and volume.
• By line value. A line worth twice as much carries twice the share. Often the fairer choice for duty, which is charged on value.
• By hand. Enter each line's share yourself. CogsIQ checks the shares add up to the cost before it accepts them.

A cost can also go to only some lines, so the freight for one carton of a split shipment lands on the products that were in it and nothing else.

Every split is rounded so the shares sum back to the invoice exactly. Three lines sharing $100.00 come out as $33.34, $33.33 and $33.33, never three times $33.33 with a cent lost.

Each dollar belongs in exactly one place, or it is counted twice:

• Inventory costs got units ready to sell: freight, customs, duty, labelling and prep. They go on the purchase order and into landed cost.
• Fulfilment costs are charged per order, by TikTok or your 3PL. They arrive with your settlements or as a per-order handling fee, and never sit on a purchase order.
• Overheads like software, contractors and lead generation are operating expenses. They reduce the shop's profit but never a single SKU's cost.

Each cost type carries its kind, and adding a fulfilment or overhead type to a purchase order shows a warning, so the slip is caught where it happens.

Freight and customs invoices often arrive after the stock has started selling. In a spreadsheet, those sales keep the cost they were given on the day, and the margin you reported stays quietly wrong.

In CogsIQ you add the invoice to the purchase order it belongs to. Landed cost recalculates, and because every sale is costed against the batch it came from (FIFO batch costing), every unit already sold from that batch is re-costed with it. Last month's profit corrects itself.

If a batch's cost was simply wrong, you can revalue it with a reason. The change is kept on record and flows into every sale drawn from that batch.

• Enter a purchase order on one page: lines, costs, receipts and shipment tracking.
• Upload an Alibaba orders export. Each order is sorted into a product purchase order or a logistics cost, and logistics costs are attached to the purchase orders they paid for, split by units, by value or equally.
• Import historical purchase orders from a CSV when you start.
• Attach invoices, receipts, packing slips and contracts to each purchase order.

The weighted average landed cost of each product is shown too, as the figure for valuing the stock you hold. The cost of a sale comes from its batch.
