ProfitEngine — Purchasing & Inventory

Yes. ProfitEngine works on top of WooCommerce and needs WooCommerce 8.0 or newer to be installed and active.

Yes. Each variation has its own cost, supplier and stock, and is forecast and ordered separately.

For each order line: revenue (after discounts and refunds, excluding tax) minus the product cost, its share of shipping, payment fees and any other costs you configure. Tax is excluded by default because it is passed on to the tax authority; you can include it under Settings.

No. The cost of each sale is recorded when the sale happens, so your history stays accurate even when your purchase costs change later.

Only if you want it to. Under Settings → Revenue recognition you choose which order statuses count. By default Processing and Completed orders count; Cash-on-Delivery stores usually untick Processing so revenue is only recognised once an order is Completed (delivered and paid).

Yes. Go to Settings → Historical profit and run the backfill. It processes your past orders in the background in small batches.

Only when you receive a purchase order: the received quantity is added to the product’s stock. If stock tracking was off for that product, it is turned on and the received quantity becomes its starting stock. It never changes your prices or other product data.

The Stock & costs window only holds settings; nothing there places an order. Click Create purchase order at the bottom of the window to open a new purchase order with the product already added (every variation for a variable product), its supplier selected and the supplier unit cost filled in. Adjust the quantities, then create the draft or send it. You can also start from Purchase Orders > New purchase order, or from the Reorder screen.

Supplier unit cost is what a supplier charges you per unit, in that supplier’s currency. It pre-fills purchase orders and the estimated spend on the Reorder screen. Unit cost for profit is your actual cost per unit in your store currency, and it is what ProfitEngine uses to calculate profit on each sale. It starts from the supplier unit cost and then updates automatically every time you receive stock (weighted average or last purchase cost, as set in Settings), so it can include shipping and other landed costs. Changing it affects new sales only; past sales keep the cost they were recorded with.

The full cost of getting stock into your store: the supplier’s price plus a share of shipping, customs, handling and other order costs. ProfitEngine spreads those extra costs across the products in a purchase order by value, so each product’s cost (and therefore your profit) is accurate.

If you can claim the tax back, leave it as recoverable, and it stays out of product cost. If it is a non-refundable tax or import duty, tick Non-refundable and it is added into the landed cost of the products.

Yes. Set the purchase order currency and an exchange rate to your store currency. Costs are converted to your store currency when stock is received.

Weighted average blends the cost of the stock you already have with each new delivery, which smooths out price changes. Last purchase cost always uses the most recent delivery’s cost. Choose under Settings → Cost basis .

Critical means the stock will run out before a new order could arrive (days of stock left is less than the supplier’s lead time). Warning means stock is at or below its reorder point. Recommended means it will run low within your coverage period. Products with no recent sales are not listed.

Automatically every night, and whenever you click Recompute forecasts on the Reorder screen. Forecasts are calculated in small background batches so large catalogues don’t slow your site.

Open the product’s Stock & costs window. The Stock section lists each variation with its current stock: type the quantity you counted, choose a reason and save. ProfitEngine updates WooCommerce stock and logs each change (who, when, why and by how much) in the product’s recent stock history. Variations that WooCommerce isn’t tracking show an Enable tracking button with a starting quantity.

Yes. When you enable stock tracking on a variable product, choose One shared stock (the same as WooCommerce’s “Track stock quantity” on the product) or Separate per variation . You can switch later from the Stock section in the product’s Stock & costs window, and the quantity is carried across. With shared stock, every variation shows the same days of stock left, and each one’s suggested order is based on its share of recent sales, so the suggestions add up to what the whole product needs.

Yes. Set them per product (or per variation). Leave them empty and ProfitEngine calculates them for you from sales velocity, lead time and your safety-days setting.

Each purchase order has a printable version with your logo, which you can print or save as a PDF and send to your supplier. Add your logo under Settings → Purchase order branding .

Yes. Every report can be exported to CSV or PDF.

No. ProfitEngine only loads its scripts on its own admin screens, records profit with a lightweight step when an order’s status changes, and runs heavy work (forecasts, backfill) in the background using WooCommerce’s Action Scheduler.

Yes. ProfitEngine declares full compatibility with WooCommerce HPOS.

Administrators and shop managers (any role that can manage WooCommerce). Other users cannot see its screens or data.

Not unless you ask it to. All data is stored in your own WordPress database. The only time ProfitEngine contacts an outside service is when you turn on a notification channel such as Slack or Telegram, and then it only sends the stock alert itself. See the External services section for exactly what is sent.

Yes. Open ProfitEngine > Notifications, turn on a channel, paste its webhook URL (or, for Telegram, your bot token and chat ID), save, and press Send test . Email is also available and needs no setup. Each channel has a link to its official setup guide.

No. Only real changes alert: a product becoming critical, or dropping to its reorder point. Alerts raised at the same time are grouped into one message, and the quiet period (24 hours by default) stops the same product or purchase order alerting again. If you prefer one message a day, turn off the instant alerts and use the daily digest.

Yes, with the Custom webhook channel. It posts each alert as JSON to any https URL, so you can forward it anywhere those tools reach, including WhatsApp. Add a signing secret to verify the X-ProfitEngine-Signature header (HMAC-SHA256 of the request body).

It is retried automatically up to 3 times over about half an hour. The channel shows its last delivery result, and the delivery log on the Notifications screen lists recent sends with any error from the service.

It does not store customer personal data. Profit records contain only order IDs and product figures. It stores the supplier contact details you enter (contact name, email, phone and address).

Deactivating never removes data. Deleting the plugin also keeps your suppliers, purchase orders and cost history, so you can reinstall without losing anything. The only exception is if you turn on Settings → Delete all plugin data when uninstalled , which removes everything.

Yes. All text is translatable, and a translation template is included.
