German invoices, ready before you seal the parcel
Open the order, click once, and the PDF is done: in German, with your own invoice number. The address, the items and the tax come from the order.
The app reads your orders and your store's details and changes nothing. Your store, theme and checkout stay as they are.
Invoices and delivery notes are free, one order at a time. Paid plans start with a 14-day free trial.
One order, three documents
Invoice
For your customer and for your books. It shows the net amount per tax rate. If you are a small business under § 19 UStG, the note for that stands in place of the tax; for a business buyer elsewhere in the EU, the note under § 6a UStG.
Delivery note
Goes in the parcel. It lists the items and the quantities and no prices, which is what you want when the order is a gift.
Credit note
A mug comes back, you refund it in Shopify, and one click makes the credit note. It names the invoice it corrects. If you cancel an order that already has an invoice, before any money is paid and before anything ships, a cancellation invoice cancels that invoice. Both are on the Starter plan.
E-invoices
Selling to consumers, you need no e-invoice. The duty only covers invoices between businesses that are both based in Germany: issuing from 2027, or from 2028 with a turnover of 800,000 € or less the year before. Every business has had to be able to receive them since 1 January 2025. That is the German finance ministry's FAQ, as of 23 March 2026.
The app makes PDF invoices, not XRechnung or ZUGFeRD. From 2027 you have to issue e-invoices to businesses that, like you, are based in Germany, from 2028 if your turnover the year before was 800,000 € or less. That does not apply to a Kleinunternehmer or to invoices up to 250 €. For that duty you will need other software. The guide to e-invoices sets out what applies when.
How it works
-
01
Your details, once
Company name, address and tax number go on every document. What your store already knows about you is filled in. You check it and set your numbers.
-
02
Open the order, click
From the app's order list. In Shopify, "More actions" on the order takes you to that order in the app. There one click makes the PDF. If the goods have not gone out yet, the app first asks when they will.
-
03
Send it yourself
You download the PDF and send it the way you always do. The app never emails your customers.
Your numbers
| Order | Invoice |
|---|---|
| #1185 | RE-2026-316 |
| #1186 | RE-2026-317 |
| #1187 | RE-2026-318 |
You set them
You choose the prefix and the next number, separately for invoices, delivery notes and credit notes. Coming from another program, you carry on from your next number.
They stay put
A number once issued never changes. Click a second time and the same file comes back under the same number. If an edit only adds new items without a discount after the invoice, you create a separate invoice for them with the next number.
On the Pro plan you download every invoice, credit note and cancellation invoice as a CSV file, for one month or for all of them. Each row is one document at one tax rate: number, date, order, tax rule, net, tax and gross.
Why it is safe to install
The app writes nothing to your store
It reads your orders and makes PDF files from them. It changes no order, no product, no theme and nothing in the checkout. If the app is down, your store keeps working.
The tax comes from Shopify
The app prints the tax Shopify calculated, the tax on shipping included. When the figures do not match, it creates no document and tells you so.
You can leave any time
You uninstall in your Shopify admin. The PDFs you downloaded stay yours. What we hold about your store is deleted about 48 hours after you uninstall, when Shopify tells us the store has removed the app. If that notice does not reach us, we delete it ourselves, at the earliest 14 days after you uninstall and normally within 30 days. After that, only the record that we handled Shopify's notices, with your store's web address, stays up to 30 days.
Plans
You pay through your Shopify bill. Paid plans start with a 14-day free trial. You change or cancel the plan in the app, whenever you want.
Support
Write to support@larchline.co, in English or in German. We answer within 24 hours. The answers to the common questions are on the support page. Larchline DATEV Export, another app of ours, turns a month's sales into a booking batch for your tax adviser. Shopify is reviewing it now, so you cannot install it yet.
