Troubleshooting

A barcode will not scan

Purser matches on the barcode stored against the variant in Shopify. If a scan finds nothing, the usual cause is that the barcode field on that variant is empty or holds a different code from the one printed on the box. Check the variant in Shopify first.

I received stock and Shopify did not update

Purser will not tell you a receipt succeeded when it did not. If some lines failed to write, it says which ones. Retrying is safe — Purser will not double-count lines that already went through. If it keeps failing, the cause is usually a permissions or location problem on the Shopify side; email us with the purchase order number and we will look.

The cost looks wrong

Two common causes. First, the opening cost: if you imported history with a blank or wrong cost column, every average calculated from it inherits that error. Check the item's opening cost. Second, expectation: Purser shows a weighted average, so it will not match the price on your most recent invoice, and it is not meant to. See 'How weighted-average cost works'.

The margin says nothing at all

Margin needs both a cost and a retail price. If either is missing, Purser shows the margin as unknown rather than guessing. An unknown margin displayed as 0% or 100% would be a lie, and this is a finance app.

My supplier appears twice

Almost always an import artefact — a trailing space or a different spelling in the CSV created a second record. Check your supplier list after any import.

Still stuck

Email us. Include your shop's myshopify.com address and the purchase order or bill number involved, and you will get a person, not a form.
