easy-verifactu

Easy Verifactu connects your WooCommerce store to your Easy Verifactu account so 
that the invoices for your orders are generated, stored, and reported to the 
Spanish Tax Agency (AEAT) under the Verifactu system, without you leaving WordPress.
The plugin does not generate or store invoices itself. WooCommerce sends each 
confirmed order and refund to Easy Verifactu, and Easy Verifactu does the fiscal 
work: it issues the invoice, signs it, keeps the immutable record required by 
Verifactu, and submits it to AEAT.
An active Easy Verifactu account is required. You can create one at 
https://easyverifactu.com. After installing the plugin you connect it to your 
account with a pairing token from your Easy Verifactu dashboard.
<h4>What the plugin does</h4>
<ul>
<li>Sends orders and refunds to Easy Verifactu. When an order is confirmed, 
updated, or refunded, the plugin notifies Easy Verifactu so the corresponding 
invoice or correction is issued and reported to AEAT.</li>
<li>Collects invoicing details at checkout. Buyers can request a full invoice 
and enter their tax ID (NIF/CIF). Works on both the WooCommerce Blocks 
checkout and the classic (shortcode) checkout.</li>
<li>Requires a tax ID for larger orders. When an order total reaches the 
configured invoice threshold for euro-priced stores, the tax ID becomes 
required at checkout.</li>
<li>Validates tax IDs in real time. The NIF/CIF entered at checkout is checked 
against Easy Verifactu so buyers get immediate feedback before they pay.</li>
</ul>
<h3>External services</h3>
This plugin relies on the Easy Verifactu service to do its work, so it sends data 
to Easy Verifactu (operated by the company behind https://easyverifactu.com). No 
other third-party services are contacted.
It connects to two Easy Verifactu endpoints:
<ol>
<li>
Easy Verifactu API (<code>https://woo.easyverifactu.com</code>) 
Used to verify your pairing token and to validate tax IDs entered at 
checkout.
<ul>
<li>When: when you connect the plugin in the settings page, and each time a 
buyer enters a tax ID (NIF/CIF) during checkout.</li>
<li>Data sent: your pairing token; and, for tax-ID validation, the buyer’s 
tax ID (NIF/CIF), name or company name, and billing country.</li>
</ul>
</li>
<li>
Easy Verifactu order ingest (<code>https://woo-ingest.easyverifactu.com</code>) 
Used to notify Easy Verifactu of order and refund activity so invoices are 
issued and reported.
<ul>
<li>When: when an order is created, updated, status-changed, or refunded.</li>
<li>Data sent: your pairing token, the WooCommerce order ID, the order 
number, and the order’s creation and last-modified timestamps. No customer 
names, addresses, line items, or payment data are sent in these events.</li>
</ul>
</li>
</ol>
Easy Verifactu may also call your store back on an authenticated endpoint to 
read the installed plugin version, so it can let you know when an update is 
available. This requires your pairing token; the version is never exposed 
publicly.
