Profit & Cost Reports for WooCommerce — profit report and cost of goods

Profit & Cost Reports for WooCommerce shows how much you earned, not just how much you sold. WooCommerce counts revenue but knows nothing about what the goods cost you. The plugin adds a cost price to products and variations, freezes it into every order line at the moment of purchase and builds a report: net sales, cost of goods, gross profit and margin for any period.

What the customer sees

Nothing — on purpose. Costs are stored as hidden product and order-line data and never reach the storefront, e-mails or customer-facing REST responses. Checkout, cart and product pages stay exactly as they were, classic or block.

What the admin gets

• Cost on the product. Product data → General → “Cost price”. On variable products — on every variation; a variation without its own cost uses the parent’s. The product list gets a Cost column.
• Profit report under WooCommerce → Profit Reports: today, 7 or 30 days, this or last month, this year or any range. Tiles for net sales, cost of goods, gross profit, margin and orders, plus profit by product.

How it works — step by step

1. You enter costs on products (or, in Pro, in one go: “cost = 60% of price” for every product without a cost, optionally in one category).
2. A customer places an order — classic or block checkout — or you create one in the admin or via REST. The plugin copies the current cost into every order line.
3. The purchase price changes and you update the product cost. The profit of orders already placed stays what it was at the moment of sale.
4. A refund is subtracted from sales; if items were returned, their cost comes back too. Amount-only refunds leave the cost alone.
5. The report reads the WooCommerce Analytics tables with the same excluded statuses and date type you set in Analytics, so its numbers match the rest of your store reports.

Under the hood

• Snapshot on the order line — unit cost and line cost are written to the item meta when the order is saved, so past profit never depends on today’s prices.
• Analytics tables as the source. Queries are aggregated and cached for 30 minutes, so the report does not load the store on every visit.
• One currency at a time. Orders in different currencies are never mixed; the currency filter defaults to the store base currency.
• Analytics columns (Pro) are added through the standard WooCommerce Admin filters — both to the table and to the downloadable CSV.
• Nothing on the storefront — no scripts, styles or requests for customers.
• Uninstall keeps costs and snapshots by default; full data removal is a setting.

Installation

1. Plugins → Add New → Upload Plugin: choose the plugin archive and activate it.
2. Open a product → Product data → General and fill in “Cost price” (on variable products — on each variation).
3. Open WooCommerce → Profit Reports.
4. For Pro: paste the licence key from the purchase e-mail or start the 7-day trial, add payment fees, shipping and monthly expenses — net profit appears in the tiles.
