</ul>
<h4>Important Warnings</h4>
<p><strong>Before using this plugin in production:</strong></p>
<ol>
<li><strong>Enable Test Mode</strong> in both FluentCart and Billingo</li>
<li><strong>Generate test invoices</strong> to verify everything works correctly</li>
<li><strong>Consult with your accountant</strong> to ensure the plugin meets your accounting requirements</li>
<li><strong>Review all generated invoices</strong> for accuracy</li>
<li><strong>Test all edge cases</strong> relevant to your business</li>
</ol>
<p><strong>This plugin generates official accounting documents. Incorrect invoices can have legal and tax implications.</strong></p>
<h4>API Usage Costs</h4>
<p><strong>Billingo charges for API usage.</strong> This plugin uses the Billingo Agent API to generate invoices automatically, which is a paid service. Review the <a href="https://www.billingo.hu/szolgaltatasok/api" rel="nofollow ugc">Billingo pricing</a> before enabling automatic invoice generation.</p>
<h4>Limitations</h4>
<ul>
<li><strong>VAT Rates</strong>: Only explicit rates supported (0%, 5%, 18%, 27%). Named VAT keys (AAM, TAM, TEHK) are not supported.</li>
<li><strong>Document Types</strong>: Only Invoices can be generated. Receipts and Pro forma invoices are not supported.</li>
<li><strong>IPN</strong>: Instant Payment Notification is not yet supported.</li>
<li><strong>Lag</strong>: Customers might need to wait a few seconds on the order conrifmation page before being able to download the invoice.</li>
<li><strong>Shipping VAT</strong>: FluentCart shipping VAT may contain <strong>minor rounding errors</strong>. This is a known bug in FluentCart, which will be corrected in the following releases. The shipping VAT on the <strong>invoice is calculated correctly</strong> according to Hungarian legal regulations. This may cause a small difference (fraction of a Forint) between what the customer pays, and what appears on the invoice.</li>
</ul>
<h4>Language Support</h4>
<p>The admin interface is available in:<br />
* English (Default)<br />
* Hungarian (Magyar)</p>
<p>The interface language follows your WordPress language settings.</p>
