Skomi Analytics for WooCommerce

Description

An add-on to Skomi Analytics. That plugin loads the script; this one gives it
the two events a shop needs.

What it reports

• purchase on the thank-you page — the order total, its currency and its order
  number.
• begin_checkout when the checkout form is shown with something in the cart.
  Not a goal in itself: it is the denominator for the rate most shops are
  actually trying to move.

Why the order number matters

A thank-you page is reloaded. Somebody refreshes it, presses back, or opens the
confirmation email a week later and lands on the same URL. Without an order
number each of those is another sale.

This plugin defends twice. It flags the order as reported, so it returns early
ever after — and it sends the order number, which Skomi uses to drop a repeat of
an order it has already counted. The first stops the request; the second stops it
mattering if the flag is ever lost to a migration.

Currency

Skomi never converts between currencies. A sale in euros is reported in euros
beside a sale in dollars, and each order’s own currency is sent with it. There is
no single cross-currency total, deliberately — that sum has to happen somewhere
that knows which rate on which day.

What it does not report

Line items. Skomi keeps at most 25 properties per event and stores them as text,
so an order of ten products does not fit — and there is no product dimension
anywhere in Skomi to put them in. Which product sold is a question for
WooCommerce’s own reports, and always will be.
