Setting quantities and costs on a PO
How to set and update quantities and costs on purchase order line items.
Setting quantities and costs
Accurate quantities and costs on your purchase orders are essential for correct inventory tracking and cost of goods reporting. PO Flow makes it easy to set and update these values.
Setting quantities
When you add a product to a PO the quantity defaults to 1. Click the quantity field in the line items table to edit it. You can type any positive whole number. The line total updates automatically.
Setting unit costs
The unit cost field is pre-filled from the product's cost per item in Shopify. If no cost is set in Shopify the field will default to zero and you will need to enter the cost manually. The cost should represent what you pay the supplier per unit — excluding any landed costs such as freight which are tracked separately.
Line totals and PO total
The line total for each row is calculated as quantity × unit cost. The PO total shown at the bottom is the sum of all line totals plus any landed costs that have been added to the PO.
Cost Update on Receipt (Pro)
If you are on the Pro plan you can configure PO Flow to automatically update your Shopify product costs when stock is received, using either the Replace method (replaces the existing cost with the PO unit cost) or the Weighted Average method (calculates a new average based on existing stock and the new receipt). This keeps your Shopify product costs accurate without manual updates. Configure this in Settings → Purchase Orders.
