Quantities and costs

Set a quantity and unit cost per line; cost auto-populates from the variant's inventory unit cost where available.

Quantities and costs

Each line item has a quantity and a unit cost. The line total is quantity times unit cost. The PO total is the sum of all line totals plus tax and shipping.

Quantity

Whole numbers only. Quantity is the number of units you are ordering. Once stock has been received against a line, the received quantity is shown alongside.

Unit cost

Unit cost is the price per unit you are paying the supplier. When you add a line via product search or import a SKU, PO Flow auto-fills the unit cost from the variant's inventory unit cost in Shopify (this is the cost field on the variant, not the customer-facing price).

When auto-fill does not work

  • If the variant has no inventory unit cost set in Shopify, the field stays empty for you to fill in.
  • If the SKU is not found during a CSV import, PO Flow warns you and leaves the cost as you entered it (or 0 if blank).

Overriding the cost

You can edit unit cost on any line at any time before the PO is fully received. The change is recorded in the PO history.
