See POAS vs revenue-only reporting
Profit Bid connects store costs to ad spend so you bid on margin — not vanity ROAS.
POAS before vs after completing cost per item
- Assumed POAS
- Real POAS
Once the cost field is filled, reported POAS drops to reality — and bidding can finally optimize true margin.
Track POAS automatically from your store — upload profit conversions and scale winners with A/C/X labels.
The cost per item field
Under each variant's pricing, Shopify offers a 'cost per item' field. It is optional, so many catalogs leave it empty — which makes profit reporting impossible.
Populate it in bulk (CSV or apps) so every variant carries a cost.
From cost field to POAS
Once cost is present, sync orders and cost to compute gross profit per order, then upload profit-weighted conversions to Google Ads.
POAS before vs after completing the field is usually a step-change in accuracy.

Frequently asked questions
Common questions about this topic — tap to read answers.
Can I bulk-import cost per item?
Yes — via CSV export/import or inventory apps. Then keep it updated as costs change.
Does Shopify calculate profit for me?
Shopify shows some margin reports, but for ad bidding you need per-order profit uploaded as conversion values — that is what Profit Bid automates.
