Questions

No. The cost recorded against each order line at the moment it was placed is never rewritten. Editing the product, recalculating the order, importing a price list and running a bulk update all leave it alone.

It reduces profit this month, on the refund date, for the quantity actually returned. A closed month never changes underneath you.

As its own line. It is not spread proportionally across unrelated products, because that would move profit between products that had nothing to do with it.

The plugin tells you how much of the last 90 days' revenue is standing on lines with no cost, lists the gaps worst-first by how much profit each one is overstating, and lets you fill them in from that screen. It never reports a missing cost as a 100% margin.

Yes. It fills in the lines that lacked one, marked as an estimate, and never overwrites a real figure. Estimates can be excluded from every report.

Both. Gross profit is revenue less the cost of goods. Net profit also takes off what each parcel cost you and the payment provider's fee, and adds back the delivery the customer paid for — set per shipping method and per gateway in Settings. Landed cost is not included, and costs are static per product: no weighted average, no FIFO. Fixed costs such as rent and salaries are coming to Pro.

No. Each order's currency is recorded, but figures are summed as one currency, so a shop selling in several will see them added together.

No. Pro's replenishment screen says what to order and how much, with the arithmetic shown, and exports the list as a CSV. Suppliers, purchase orders and goods receipts are not part of it yet, and lead time is one global setting rather than per supplier.

It adds 4.4 ms to a checkout. The dashboard renders twelve months of 20,000 orders in 39 ms, and the product list uses three queries regardless of page size — with tests that fail the build if those query counts change.

The free plugin does not: no outbound requests and no telemetry, checked by a test that scans its code. Pro talks to Freemius, which sells and licenses it, to check the licence and deliver updates: that carries the licence key, the site's address, and the versions of Pro and its SDK. WordPress and PHP versions and the list of other plugins are optional, and can be switched off on the activation screen. No shop data — orders, customers, products, figures — is ever sent.

One-click import from WPFactory Cost of Goods, SkyVerge Cost of Goods and ATUM Inventory Management. Where those plugins recorded what a past order cost at the time, that figure is used — it is better evidence than today's price. Costs you already entered are never overwritten.

Yes, from the first line of code. HPOS and legacy order storage are both tested in CI.

It stays. Deleting everything on uninstall is a setting, off by default, because cost history is the one thing a shop cannot recreate.

The free plugin costs nothing, has no product limit and never expires. Pro, which adds stock replenishment, is €89 a year for one shop or €179 a year for five. The first hundred founding members can have Pro for one shop for life for a single €199. Prices exclude VAT, which is added at checkout where it applies.

Yes. Pro can be tried for 14 days without a card. When the trial ends Pro switches off unless you buy a licence; the free plugin and everything it recorded carry on as before.

By email, from the people who wrote it, for anyone with a Pro licence or trial. Free users can write too, and the WordPress.org forum will be read once the listing is approved.

Pro switches off a week after the licence ends, and a trial switches off the day it ends. The free plugin keeps working, nothing is deleted, and renewing brings Pro back with every setting where you left it.
