Best & Free App for sending customers invoice

Payments + Shipping & Fulfilment

Topic summary

Seeking a free/low-cost way to email customers invoices post-purchase and to bulk-download invoices for annual accounting, including Germany-specific legal requirements.

Recommendations and options:

  • Order Printer Pro: adds a PDF invoice download link to Shopify email receipts; free plan for stores with <50 orders/month; part of Shopify’s Order Invoice apps collection.
  • Order Printer: customize invoices/packing slips and bulk print/download invoices directly from the Orders page via More actions.

Addressing German legal requirements:

  • Edit the Order Confirmation email in Shopify Admin > Settings > Notifications to add the legal phrase via HTML.
  • Insert invoice date using Liquid (Shopify templating) code: {{ created_at | date: “%m-%d-%Y” }}. Note: it won’t appear in the admin preview without a real order.

Accounting exports:

  • Shopify Analytics can export sales data, but it doesn’t provide PDF copies of order confirmations/invoices.

Outcome and status:

  • Technical steps provided to include required details in confirmations and to bulk download/print invoices via apps.
  • No final confirmation from the poster; discussion appears close to resolved, pending adoption of Order Printer/Order Printer Pro.

Hi Mac,

Thanks for your reply.

I was seeking an invoice app for 2 reasons:

  1. because I need a way to bulk download all the invoices I send to customers for my yearly accounting.

  2. because the order confirmation misses additional details that are legally required in Germany.

  • Invoice Date
  • A small legal phrase at the end of the invoice.

Am I able to do both of those things with the order confirmation, maybe I just don’t know it well enough. Thanks for your help.
