Managing Purchase Prices (Unit Cost) in Shopify

Guide · approx. 4 min read

Without clean purchase prices, every calculation is guesswork. Shopify stores the purchase price as unit cost per variant — here's how to maintain it efficiently.

What is unit cost?

Unit cost (cost per item) is Shopify's field for the purchase price of a variant. It sits in each variant's inventory and is the basis of every calculation. Without a maintained unit cost you don't know your margin.

Why cost prices go stale

Suppliers change prices, new variants arrive without a cost, old stock has gaps. Across hundreds of variants, upkeep quickly gets messy — especially if you have to open each variant in Shopify individually.

Maintain cost prices efficiently

It's more efficient to have one overview where you see all variants, filter by collection, vendor or tag, and update prices individually or in a batch. A status shows you instantly which variants still have no cost price.

Manage cost prices centrally

PriceCalc Pro shows all variants with their unit cost, filters by collection, vendor, tag and SKU, and saves changes individually or in a batch — straight in Shopify.
