Advanced PDF Invoice creates invoices, proforma invoices, credit notes, packing slips, delivery notes and pick lists for every order. The PDFs are attached to OpenCart's own order emails, can be downloaded in the admin and in the customer account, and are designed with a visual template designer with live preview.

DOCUMENTS

• Invoice - issued automatically on the order statuses you choose, with its own legal number. The order data is frozen once issued, so a reprint never changes.
• Proforma invoice - for unpaid orders (bank transfer, cash on delivery) with your bank details and a payment QR code.
• Credit note - refund products, shipping or any amount. Own numbering, refers to the original invoice. Returns fill in the quantities.
• Packing slip and delivery note - without prices, with tick boxes and signature lines.
• Pick list - the products of all selected orders added up, sorted by warehouse location.

TEMPLATE DESIGNER WITH LIVE PDF PREVIEW

• 6 ready-made themes: Classic, Modern, Minimal, Corporate, Bold and Bilingual (e.g. Arabic + English)
• Your colours, fonts, logo, signature and company stamp
• Drag & drop sections; choose the product table columns (image, model, SKU, options, HSN, tax, weight ...)
• Terms, footer, notes and custom blocks per language, with placeholders
• A4, Letter, Legal, A5, A3 - portrait or landscape, margins, page numbers
• Code 128 barcode and QR code (order link, document number or ZATCA)
• Preview with sample data or any real order, in any language
• Export and import templates between shops

EMAILS - WITHOUT CORE EDITS

• Invoice or proforma attached to OpenCart's own emails (order confirmation and order status update)
• Optional copy for the shop owner's new-order alert
• "Download your invoice" button in the email - a secure link that also works for guest orders
• Warehouse copy - packing slip, delivery note or invoice sent to your fulfilment address
• Works with any email design, including Email Templates Pro

INVOICE NUMBERS YOU CAN TRUST

• Gap-free numbering per document type - patterns like INV-{Y}-{SEQ}, yearly or monthly restart, per store or shared, start where your old system stopped
• One number per order - OpenCart's own "Generate invoice" button uses the same numbering, and orders already numbered by OpenCart keep their number
• No accidental numbers - opening the PDF of an order without an invoice shows an unnumbered DRAFT; invoices are only issued on purpose
• Invoice register (CSV) for your accountant: net, tax, total, currency, customer VAT number

TAX & COMPLIANCE

• EU / UK VAT - customer VAT number, tax summary per rate, automatic reverse-charge note
• India GST - HSN/SAC column, CGST + SGST or IGST split, UPI payment QR
• Saudi Arabia - ZATCA e-invoice QR code (phase 1), bilingual Arabic/English layout
• Amount in words in the customer's language
• SEPA (EPC / GiroCode) payment QR on EUR invoices
• PAID / UNPAID watermark

ADMIN & CUSTOMERS

• PDF button on every order row (red = invoiced, grey = draft) and a bulk PDF menu in the order list - one merged PDF or a ZIP with one file per order
• PDF documents card on the order page: issue, view, download, email, credit note
• Customers download their documents in My Account; they can only open their own
• Multi-store (own settings, numbering and template per store) and multi-language (labels in English, Arabic, French, German, Spanish - add more with one file)
• Right-to-left (Arabic, Hebrew, Persian, Urdu) with correct letter joining; upload your own fonts for Chinese, Japanese, Korean, Thai or Indic scripts
• Optional PDF password and PDF archive
