Order Printer Pro alternative: e-invoicing, archive and DATEV for Shopify

By · Published

Rechnungskit issues the invoice for every Shopify order itself: with its own number sequence, as ZUGFeRD under EN 16931, locked in the GoBD archive and as a finished DATEV booking. Order Printer Pro designs and sends PDF documents from the order; the invoice number there is the Shopify order number. Structured e-invoices are available through a paid add-on as a separate XML file (UBL or CII) or via Peppol. The provider does not describe a ZUGFeRD PDF with embedded data. Shopify's own free app "Shopify Order Printer" is purely a printing tool for invoices, packing slips and pick lists.

The short version

Rechnungskit fits if …

every order should become an e-invoice with your own number sequence, archived and locked, arriving at your tax advisor as a DATEV booking, including cancellation invoices on refunds and payout reconciliation.

Order Printer Pro fits if …

above all you need nicely designed documents: invoices, packing slips, delivery notes and quotes with free Liquid templates, bulk printing and receipts at the point of sale. Accounting and e-invoicing you then solve elsewhere.

Order Printer Pro is a design and printing tool for Shopify, Rechnungskit is an invoicing and accounting chain. For packing slips and delivery notes, both fit side by side; the invoice itself should come from one system.

When is Order Printer Pro the better choice?

Rechnungskit doesn't do everything. In these cases, Order Printer Pro is the more honest recommendation.

You need packing slips and delivery notes

Besides invoices, Order Printer Pro prints packing slips, delivery notes, receipts, quotes from drafts and return forms, in bulk for many orders at once. Rechnungskit only creates invoices and correction documents. So you can keep Order Printer Pro for the shipping table and just switch off the invoice template there.

Document design matters most to you

Templates in HTML, CSS and Liquid, metafields, barcodes, QR codes and more than 30 languages: Order Printer Pro gives you much more design freedom. In Rechnungskit you set the logo, texts and layout; there is no template code.

You rarely sell to businesses and your tax advisor books by hand

With few orders a month, no cross-border sales and a tax advisor who splits Shopify payouts themselves, a decent PDF is often enough. Up to 50 orders a month, Order Printer Pro costs nothing.

What Rechnungskit does differently

Invoicing

Invoicing on the correct date of supply

Shipped goods are invoiced on the shipping date, not the payment date. It sounds like a detail, but it decides which period the revenue lands in.

Date of supply (Leistungsdatum) from the shop's shipping event
Small-amount invoices automatically under §33 UStDV
Handover to DATEV in the right period
Tax compliance

VAT ID check with evidence archive

Qualified check with the BZSt (Federal Central Tax Office) including company name, city, postcode and street. The response is archived unchanged for eight years and linked to the individual invoice.

Qualified BZSt check instead of a simple format check
Response linked to the invoice and delivery date
No tax-exempt invoice without a usable check
Accounting

DATEV bookings with linked documents

Your tax advisor gets finished EXTF booking records, not just a folder of PDFs. Revenue, payments, fees and payouts are already matched, and every invoice booking carries a Beleglink to its document image in the "Belegtransfer" package for Unternehmen online.

EXTF bookings for SKR03 and SKR04
Document image attached to the booking via Beleglink
Fees and payouts already matched
Your tax advisor downloads them directly

Worked example
600 documents a month: at Rechnungskit that is a €9.00 base fee plus €66.50 usage, including e-invoicing, GoBD archive and DATEV bookings. At Order Printer Pro, the Growth plan at $20 applies, $30 with the e-invoice add-on. That gets you PDF documents and XML files; an archive with locking, DATEV bookings and payout reconciliation are not included. For 500 orders the Starter plan is enough ($10, $20 with the add-on).

Order Printer Pro
$30 with e-invoice add-on

Switching in three steps

1
Bring your data over

Orders and payments from your connected sources are pulled in, and your invoice number sequence continues. Old documents stay available in your previous system; Rechnungskit doesn't import invoices created elsewhere.

2
Test in parallel

Both systems run side by side for one billing period. You compare documents and bookings before anything goes live.

3
Switch over

Sending is switched over and your tax advisor gets the new export access. The old system stays in place as an archive.

FAQ

For the invoice, yes; for printing, no. Rechnungskit issues the invoice for every Shopify order, as an e-invoice with its own number sequence, archived and locked, and as a DATEV booking. Rechnungskit doesn't create packing slips, delivery notes, quotes or return forms; for those you can keep Order Printer Pro and just switch off the invoice template there.

Yes, and that's the usual way to switch. You run both systems in parallel for one billing period and compare documents and bookings before you switch over.

They stay where they are. Rechnungskit doesn't import or archive invoices created elsewhere; you keep meeting your retention duty for old documents (eight years under § 14b (1) UStG and § 147 (3) AO) in your previous system. What Rechnungskit can pull in are past orders and payments from your connected shops and payment providers, which then become new, validated invoices. For the number sequence, you set the number Rechnungskit continues from, so nothing overlaps with your old documents.

Documents are stored tamper-proof and unchangeable for eight years for as long as your account exists (WORM archive with checksums). Eight years is the retention period for invoices and accounting records (§ 14b (1) UStG, § 147 (3) AO); the requirements for the archive are set out in the GoBD. You can export them at any time, and for 90 days free of charge after you cancel. The final assessment of your process documentation (Verfahrensdokumentation) is up to your tax advisor.

Shopify Order Printer is Shopify's own free app for printing invoices, packing slips and pick lists with templates in HTML, CSS and Liquid. Order Printer Pro is a separate third-party app (Shop Circle) with automatic PDF sending, bulk export, quotes from drafts and an e-invoice add-on. Both design documents from the Shopify order. Neither documents its own number sequence, an archive with locking or a DATEV export.

No. An e-invoice is an invoice in a structured electronic format (§ 14 (1) sentences 3 and 6 UStG); according to the BMF letter of 15.10.2025, a PDF without an embedded data set does not count. Order Printer Pro offers an add-on for this that creates an XML file (UBL or CII) per order or sends it via Peppol. The XML file is built from the Shopify data and sits next to the PDF. Rechnungskit embeds the structured data directly in every invoice (ZUGFeRD), so your customers get one document that both people and software can read.

Yes, for everything except the invoice. Keep printing packing slips, delivery notes, return forms and quotes with Order Printer Pro. Switch off the invoice template and the automatic PDF sending of the invoice there, so your customers get exactly one document, the one from Rechnungskit, with your number sequence.

Legally, an invoice number must be sequential and unique, even with several number ranges (§ 14 (4) sentence 1 no. 4 UStG); the law does not require a gapless sequence. The order number usually meets that. It gets tricky with corrections: if every order has exactly one number, cancellation and correction documents need their own numbering so that no number is used twice. Rechnungskit keeps its own number sequence for this, creates cancellation invoices from Shopify refunds automatically and archives both documents locked.

From the providers' publicly available sources, checked on October 1, 2026, with footnotes for each row. Where we found no reliable source, the table says "Not documented". If you spot a mistake, write to support@rechnungskit.de and we'll correct it and re-date the page.
