Key points

What the buyer sees

The account has a Tax certificates section: type, state, file and expiry date. A certificate can also be added at checkout.

What the admin gets

The admin sees the certificate queue, opens the file, edits the data, sets the expiry and approves, rejects or revokes.

How much it costs

The base version is free. Pro costs 990 UAH for a one-year licence. A year of updates, technical support and all Pro features.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • WordPress 6.2+, WooCommerce 8.0+, PHP 7.4+.
  • WooCommerce taxes set up.
  • A backup must hold both the database and the uploads folder: without both the files cannot be read.

Full module description

Tax Exempt Certificates keeps sales tax exemption certificates in WooCommerce. The buyer uploads a document, the shop reviews it, and tax goes away only when the certificate is approved, valid and covers the delivery state.

This is not tax advice. The plugin stores documents and applies your decisions. It does not check permits with any state.

What the buyer sees

The account has a Tax certificates section: type, state, file and expiry date. A certificate can also be added at checkout. After approval tax disappears at checkout, and the buyer sees an explanation and can untick it for one order.

What the admin gets

The admin sees the certificate queue, opens the file, edits the data, sets the expiry and approves, rejects or revokes. The reason goes to the buyer by e-mail. A guest can upload a certificate, but tax comes off only for a signed-in buyer, because an e-mail typed by a guest proves nothing.

How it works, step by step

  1. The buyer uploads a certificate.
  2. The shop gets an e-mail and reviews the document.
  3. The buyer gets the decision.
  4. At every recalculation the plugin checks status, expiry and state.
  5. When the date passes, tax comes back by itself, even without WP-Cron.

Under the hood

  • The decision is made at every recalculation and is not stored ahead.
  • The plugin clears only its own exemption flag and leaves others alone.
  • Files sit encrypted in a private folder.
  • A single purchase certificate counts as used when the order is created. If payment fails, the shop resets it.

How to install

  1. Plugins → Add New → Upload Plugin: pick the zip and activate.
  2. WooCommerce → Tax Certificates → Settings: pick the certificate types.
  3. Test as a buyer: upload a file, approve it and walk through checkout.
  4. For Pro: paste the key or start the 7-day trial.

The module is not on wordpress.org yet: the free version and Pro are one archive from this page. Without a key it works as the free version.
