Invovate

Invovate Invoice Generator connects your WordPress site to the <a href="https://invovate.com/api" rel="nofollow ugc">Invovate invoice API</a> so you can create professional PDF invoices in 11 languages (including right-to-left Arabic, Japanese, Hindi, and Cyrillic).
<ul>
<li><code>[invovate_invoice_form]</code> shortcode — drop a simple “create invoice” form on any page. Visitors enter a business name, client, and line items and get a downloadable PDF link (valid 7 days).</li>
<li><code>invovate_generate( $invoice, $args )</code> helper — call from your theme or another plugin to generate invoices programmatically (e.g. on a WooCommerce order or form submission).</li>
<li>Free API key — required for the invoice form (it generates a shareable PDF link). Get a free key at invovate.com/auth and set it under Settings → Invovate. The <code>invovate_generate()</code> helper can still compute JSON totals without one.</li>
</ul>
Languages: English, Dutch, German, French, Spanish, Italian, Portuguese, Arabic, Japanese, Russian, Hindi. 20+ currencies, per-line tax, 5 templates.
<h4>Configure the form (shortcode options)</h4>
<pre><code>[invovate_invoice_form] accepts these attributes:
</code></pre>
<ul>
<li><code>fields</code> — comma list of inputs/controls to show. Available: <code>from</code>, <code>to</code>, <code>items</code>, <code>currency</code>, <code>language</code>, <code>template</code>, <code>notes</code>, <code>qr</code>, <code>link</code>. Items always show. Default: <code>from,to,items,currency,language,qr,link</code>.</li>
<li><code>from</code>, <code>to</code> — prefill (or, if not in <code>fields</code>, lock) the business and client name.</li>
<li><code>currency</code> (default <code>USD</code>), <code>language</code> (default <code>en</code>), <code>template</code> (default <code>classic</code>).</li>
<li><code>tax</code> — <code>true</code>/<code>false</code>: show the per-item Tax % field. Default <code>true</code>.</li>
<li><code>qr</code> — default state of the scan-to-view QR (<code>true</code>/<code>false</code>). When <code>link</code> is in <code>fields</code>, users get a checkbox; the QR is disabled while the link is off (it points at the link). Default <code>true</code>.</li>
<li><code>link</code> — default state of the shareable link (<code>true</code>/<code>false</code>): <code>true</code> = a 7-day shareable link; <code>false</code> = a direct PDF download with no link or QR. Default <code>true</code>.</li>
<li><code>rows</code> — number of starting line-item rows. Default <code>1</code> (an “Add item” button is always shown).</li>
<li><code>button</code> — submit-button label.</li>
</ul>
<h4>Example shortcodes (copy & paste)</h4>
Basic form, all defaults: 
 [invovate_invoice_form]
Lock your business name; the client fills in the rest (EUR, German, navy template): 
 [invovate_invoice_form from=”My Company GmbH” fields=”to,items” currency=”EUR” language=”de” template=”navy”]
Freelancer invoice in USD with a scan-to-view QR: 
 [invovate_invoice_form from=”Jane Doe” currency=”USD” qr=”true”]
Direct PDF download instead of a 7-day shareable link: 
 [invovate_invoice_form link=”false” button=”Download invoice”]
Three starting rows, with the tax field and a notes box: 
 [invovate_invoice_form fields=”from,to,items,currency,language,notes” rows=”3″ tax=”true”]
Japanese invoice (JPY, consumption tax): 
 [invovate_invoice_form currency=”JPY” language=”ja” template=”modern”]
Minimal — client name and items only: 
 [invovate_invoice_form fields=”to,items” from=”Acme Studio”]
Not regulated e-invoicing. PDF/UBL output is for interoperability and archival only — it does not provide Peppol, Factur-X, ZUGFeRD, XRechnung, or NF-e compliance or government-network delivery.
<h3>External services</h3>
This plugin connects to the Invovate invoice API to generate invoices. It is a first-party integration with a service operated by the plugin author.
What is sent, and when: Only when you submit the <code>[invovate_invoice_form]</code> form (or call <code>invovate_generate()</code> in code), the invoice details you entered — business name, client name, line items (description, quantity, unit price, tax rate), currency, language, and optional notes — are sent over HTTPS to <code>https://invovate.com/api/generate-invoice</code>. If you set an API key under Settings → Invovate, it is sent as an <code>Authorization: Bearer</code> header. Nothing is sent on page load or in the background.
What is returned: either a shareable PDF link (the invoice is stored for up to 7 days, then automatically deleted) or the generated PDF file.
