WooCommerce 10.3 added Cost of Goods Sold (COGS) to core — but it ships with no reports. You can record what every product costs you, yet there is nowhere to see what you actually earn.
Margin Lens fills that gap. It turns WooCommerce’s own COGS data into the profit dashboard your store is missing:
- Profit dashboard — revenue, cost of goods, gross profit, margin %, and profit per order for any date range, with comparison against the previous period
- Daily profit chart — revenue vs. profit over time, so you spot expensive weeks at a glance
- Top products by profit — find out which products make you money and which only make you busy
- Profit column on the orders list — see each order’s profit and margin without opening it
- Cost column + filter on the products list — instantly find products that still have no cost set, and update costs right from Quick Edit
- Profit from day one — new orders record their cost automatically. (Margin Lens Pro can backfill costs onto your existing orders.)
- One-click setup — enables WooCommerce’s COGS feature for you and walks you through the rest
Built the right way
- Uses WooCommerce’s native COGS fields — no duplicate cost database, no lock-in. Your data stays in WooCommerce even if you remove this plugin.
- HPOS compatible — works with High-Performance Order Storage and legacy storage alike.
- Fast — reports read from WooCommerce’s indexed analytics tables with caching; nothing runs on your storefront.
- Light — no ads, no admin-wide notices, no tracking.
Margin Lens Pro
Free shows your gross profit. Pro shows your real, bottom-line profit — and what’s eating it:
- True net profit — gross profit minus payment-gateway fees, shipping costs and handling, per order
- Net after marketing — log your ad spend by channel and date; Pro prorates it to the report range and subtracts it, so you see what you actually pocket
- Low-margin product alerts — automatically flags products earning below a margin threshold you set, on the dashboard and in your email report, so you know exactly what to reprice or drop
- Customer depth — top customers by profit with lifetime value, plus a new-vs-returning breakdown
- CSV exports — products, customers and daily figures for your accountant or spreadsheet
- Scheduled email reports — a weekly or monthly profit summary, including low-margin products, straight to your inbox
Everything stays on your own site — no monthly SaaS fee, no sending your sales data to a third party.

- WooCommerce 9.5 or newer (10.3+ recommended, where COGS is a stable feature)
