• Invoice generation Create an invoice for any order with one click:
• The generated invoice is saved in the order details.
• The invoice PDF is also downloaded to your website and stored with a random file name in the wp-content/uploads/wc_szamlazz folder.
• You can set a payment deadline and a note for the invoices.
• Works with coupons, they appear as negative line items on the invoice.
• Shipping is added to the invoice too.
• The PDF can be downloaded right from the Orders table, using the order actions or the optional Számlázz.hu column.
• Proforma, deposit and reverse invoices, delivery notes You can create every document type supported by Számlázz.hu for your orders.
• Bulk actions Use the bulk actions on the Orders page to create invoices and to download or print them all at once.
• VAT number field A new VAT number field is added to the billing details. The VAT number is validated, saved, and shown in the e-mail sent to the customer and in the order details.
• Logging The order notes show exactly when and which document was created.
• Mark as paid automatically Choose the payment methods for which the invoice should be created as already paid.
• International invoices If you sell abroad, for example in euros, you can change the language of the invoice and show the current exchange rate of the Hungarian National Bank (MNB) on it. Compatible with WPML and Polylang.
• And much more Paper and electronic invoices, VAT rate settings, invoice number prefix, invoices downloadable from the customer's account, e-mail notification about failed invoice generation and more.

• Automatic invoice generation Create invoices and other documents (proforma and deposit invoices, delivery notes, reverse invoices) automatically based on the order status, with custom conditions.
• Invoice notification In the free version, Számlázz.hu sends the invoice notification to the customer. In the PRO version, the invoice can be attached to the e-mails sent by WooCommerce, so you don't need to use the Számlázz.hu invoice notification and your customer gets one less e-mail.
• Automatic handling of bank transfers With the Számlázz.hu Autokassza feature, your store can be notified when a proforma invoice is paid, and the invoice can be marked as paid automatically.
• Special VAT rates Set special VAT rates (EUKT, EUT, EUFADE, etc.) for certain products on the invoice, based on custom conditions.
• Bulk actions With the bulk document generation action you can create not just invoices, but proforma and deposit invoices, delivery notes and reverse invoices too.
• Override invoice data Use conditions to change the prefix and bank account details shown on the invoice.
• E-Receipt If you sell electronic products, tickets or downloadable content, you don't need to ask for the customer's billing address, just the e-mail address, and the plugin creates an electronic receipt.
• Fill in company details automatically The VAT number field is validated with the Számlázz.hu API and the billing details are filled in automatically.
• EU VAT number The VAT number field accepts EU VAT numbers too, and removes VAT from the order automatically if the number is valid (validated with the VIES API).
• Accounting details Set accounting details for each product category, separately for Hungarian and foreign purchases: general ledger number, revenue ledger number, economic event and VAT economic event. The user ID is saved as the customer's ledger ID.
