FAQ Changelog Full documentation

  1. Install the app

    From the Shopify App Store, click Install and approve the requested permissions (read access to your orders). You'll land straight in the embedded app.

  2. Set up your branding

    Open the Settings tab and fill in your company name, address, accent colour, document title and language, and upload your logo. These values are used on every document as placeholders you can drag anywhere in the editor.

  3. Choose or design your invoice template

    Go to the Invoice PDF tab. Browse the gallery of 200+ ready-made designs filtered by industry, colour and layout, start from a blank template, or click Recreate from your invoice to upload your existing invoice PDF or a screenshot — the AI rebuilds it as an editable template with your product rows repeating automatically. Fine-tune anything with the drag-and-drop editor.

  4. Turn on auto-email (optional)

    With auto-email on, every new order automatically generates and emails a branded PDF invoice to the customer — no manual step required. You can always send or download documents by hand too.

  5. Customize the email

    In the Email message tab, start from a preset (Classic, Minimal, Itemised, Receipt, Reminder or Shipped) and adjust the wording and blocks to match your brand voice.

  6. Send your first document

    On the Send tab, pick an order and a template, then Send now or Download PDF. For a phone order, offline sale or service that isn't a Shopify order, use the Manual invoice form below it — it runs through the same numbering, template and compliance pipeline as regular orders.

  7. Track every document

    The Invoices tab lists everything the app has generated: search by invoice number, order or customer email, filter by date range, re-send or re-download any past document, or export the whole range as CSV.

  8. Turn on compliance & accounting export

    Under Settings → Advanced, enable e-invoicing (ZUGFeRD/XRechnung) if you sell in the EU, set your sequential invoice numbering (including continuing the sequence from a previous app), and connect DATEV, Lexware Office or sevDesk export for your accountant. See the full documentation for details on each option.

Tip: The in-app Guide tab always shows a live summary of everything the app does, and the Support tab is the fastest way to reach us if you get stuck on any step above.
