Version 1.0, 2026-09-23.
Effective from the day the app is listed on the Shopify App Store.

By installing or using the app you agree to these terms, including the Data Processing Agreement that is part of them. The app is for businesses. By installing it, you confirm that you use it for your trade or profession and not as a consumer. If you install the app for a company, you confirm that you can bind that company. The English text is the binding one. A German translation is provided for convenience.

1. What the app does

The app makes a booking batch in the DATEV format (a CSV file) from your Shopify orders and refunds, one calendar month at a time. Your tax adviser can import it. The app books the sales and refunds per tax rate against one collective debtor account. It uses the accounts and tax keys of your chart of accounts (SKR03 or SKR04) and of your own mapping. Each month shows a completeness line: what the batch holds, and what it left out and why.

The app does not calculate tax. It takes the amounts and the tax from the orders as Shopify calculated them. Sometimes the lines of an order or a refund differ from its total by more than 2 cents at one tax rate. Then the app does not book it and names it in the completeness line. An order in another currency than the batch's is left out and counted there too. A tax-free sale gets no default account: it waits until you choose one.

The app reads only the orders Shopify lets it read, which today are the orders of the last 60 days. For an older month it makes no file and says so.

The app does not upload anything. It connects to no accounting software, not to DATEV and not to a tax authority: you get a file and you pass it on. Shopify Payments payouts and fees are not in the file. The app does not change your orders, products or tax settings in Shopify.

DATEV is a trademark of DATEV eG. The app writes files in a format DATEV publishes. It is not a product of DATEV eG, and DATEV eG has not certified or endorsed it.

If the app is unavailable, your orders, your checkout and Shopify's own reports and order export keep working.

2. Your Shopify store

You need a Shopify store to use the app. Shopify's own terms apply to your store and to the charges for the app. The app works with the two permissions you grant at installation: reading your orders, and reading your products, of which it reads only the product type. We do not ask for more.

These terms are between you and us. Shopify is not a party to them and owes you nothing under them. As between you and Shopify, we alone are responsible for the app and for any liability from your use of it, within the limits in section 10. That includes the app's support and how we access, use and store your data. Shopify is not liable for any fault in the app or for any harm from installing or using it. Shopify cannot help you install or use the app, unless Shopify says otherwise.

3. Plans and payment

The app has three plans:

PlanPriceIncludes
Free0One closed month at a time: sales and refunds in the DATEV format, with one chart of accounts and the completeness line. For as long as you use it
Starter9.99 USD every 30 daysEverything in Free. Several closed months at the same time
Pro29 USD every 30 daysEverything in Starter. Making the file of a closed month again at any time, and the whole history of each month with every checksum. A download link for your tax adviser. Cost centres and revenue accounts per product type

Paid plans start with a 14-day free trial. Shopify bills the plan every 30 days with your Shopify invoice, in United States dollars. You can change or cancel the plan in the app at any time. When you move to a lower plan, the features that plan does not include stop working. While your store is below Pro, no link for your tax adviser works. If a link is opened in that time, or a month's page is viewed in the app, every link of your store stops working for good. Your closed months and the receipts of your files stay.

If you uninstall the app, Shopify cancels the plan and does not credit the rest of the billing period.

Shopify does not refund app charges. We may refund a charge, in full or in part, at our own discretion.

We may change prices. We tell you at least 30 days before a price change takes effect, in the way section 14 describes. A new price applies to you only after you approve the new charge in Shopify.

4. Your responsibilities

  • You are responsible for correct booking settings: the adviser number, the client number, the first day of your financial year and the length of your account numbers. The same goes for your chart of accounts, your accounts and tax keys, and your choice of the small business rule (Kleinunternehmerregelung). It also goes for the tax settings in your Shopify store. The app writes what you enter and what Shopify calculated.
  • Read the completeness line of each month. Have your tax adviser check each batch before it is posted. The app writes every batch so that it can still be changed after the import.
  • The app is a tool, not tax advice (keine Steuerberatung) and not legal advice. Which accounts and tax keys your business needs, and how a sale is to be booked, is for you and your tax adviser to decide.
  • The app keeps no copy of your files. Keep every file you pass on in your own records, unchanged and readable, for as long as the law of your country requires.
  • A link for your tax adviser works for anyone who has it, until it stops working (section 3 of the Privacy Policy). Send it only to your tax adviser, and withdraw it in the app if it reached the wrong person.
  • You are responsible for complying with the laws that apply to your store, including data protection law towards your customers and towards your tax adviser.
  • Do not use the app to mislead customers or authorities, to break Shopify's rules, or to interfere with the app or with other merchants.
  • Keep your Shopify account secure. Anyone who can use your Shopify admin can download your files, make links for your tax adviser and change your settings.

5. Support and availability

We give support in German and English at support@larchline.co. We aim to answer within 24 hours. That is our target, not a promise, and it does not cover the time Shopify needs to fix a problem on its side. Support answers questions about the app. It does not give tax advice.

We aim to keep the app running at all times, but we do not guarantee it. Shopify's systems, and any problem inside them, are outside our control.

6. Your data

How we handle data is described in the Privacy Policy, which is part of these terms. Your settings and your files are yours. We process personal data in your orders only on your instructions, and for nothing else. We use it to make your files, to show you what went out and to hand a file to whoever opens a link you made. The Data Processing Agreement is part of these terms and governs that processing.

7. Intellectual property

The app, its code and its documentation belong to us. While the app is installed, you may use it for your store. You may not copy, resell or reverse engineer it. If you send us a suggestion, we may use it without owing you anything.

8. Ending the service

  • You can uninstall the app at any time. Save the files you need first. Your data is then deleted as described in the Privacy Policy.
  • We may suspend or end your use of the app if you break these terms, if Shopify asks us to, or if the law requires it. Where we can, we tell you first.
  • We may stop offering the app. We tell you at least 30 days before, in the way section 14 describes. You then have time to save your files and move to another tool. We also cancel paid plans then, so you are not charged again.

9. No warranty

The app is provided as it is. We do not promise that it fits a particular purpose, that it is free of errors, or that it will always be available. To the extent the law allows, we exclude all warranties that are not stated in these terms. This does not affect your right to cancel a paid plan at any time. Our liability is set by section 10.

10. Limitation of liability

To the extent the law allows:

  • Our total liability to you, for all claims together, is limited to a single amount. That amount is what you paid us for the app in the 12 months before the event that caused the claim.
  • We are not liable for indirect losses, lost profits, lost sales, lost data or loss of goodwill, however they arise.
  • The two limits above do not apply to a breach of an essential duty through simple negligence. An essential duty is one that the proper use of the app depends on and that you may rely on. For such a breach, we are liable only for damage that is typical for this kind of agreement and foreseeable when you accepted these terms.
  • We are not liable for the actions of Shopify or other third parties.
  • We are not liable for tax, interest or penalties that result from your own details or settings. That covers your booking settings, your accounts and tax keys, and your tax settings in Shopify, and the tax Shopify calculated from them. It also covers a batch that was posted without being checked first, unless the loss comes from a mistake in the app's own work. It does not cover a mistake in the app's own work; the limit above applies to that.

Nothing in these terms limits liability that cannot be limited by law. That includes liability for intent, fraud and gross negligence, by us or by the people we use to provide the app. It also includes liability for death or injury to body or health caused by negligence, and liability under product liability law.

11. Indemnity

To the extent the law allows, you will cover the costs and damages we face from a third-party claim, where you are responsible for its cause. This applies to claims caused by your settings, your files, your store or your breach of these terms.

12. Law and disputes

These terms are governed by the laws of the State of Washington, United States. Disputes go to the state or federal courts located in Washington State. If the law of your country gives you rights that cannot be waived, those rights still apply. The Data Processing Agreement names its own law and courts, for itself and for the standard contractual clauses in it, and that choice applies to them.

Before starting a legal action, write to us. Most problems can be fixed by email within days. Writing to us first is a request, not a condition for going to court.

13. The rest of the agreement

  • If a court finds one part of these terms unenforceable, that part is limited or removed and the rest still applies.
  • These terms, the Data Processing Agreement and the Privacy Policy are the whole agreement between us about the app. Anything we agree with you individually in writing comes first.
  • If we do not enforce a right straight away, we do not give it up.
  • We may transfer these terms to another company that takes over the app. We tell you if that happens, in the way section 14 describes. If you do not want to continue with that company, you can cancel your plan and uninstall the app. You may not transfer these terms without our written agreement.

14. Changes to these terms

We may update these terms. For a change that matters to you, we tell you at least 30 days before it takes effect and say what changes. In that message we also point out that if you keep using the app after that date, the new terms apply. If you do not agree, uninstall the app before that date. A new price always needs your approval in Shopify, as section 3 says.

How we tell you. Where these terms say we tell you something, you get the same notice in two places. The app shows it on every page until you mark it read. It stops showing 30 days after the change takes effect, or 60 days after we post it when it names no date. We also send it by email to the address Shopify holds for your store, when Shopify gives us one. The sender is noreply@larchline.co, and you can reply to support@larchline.co. By installing the app you agree to receive these service emails. They are about the app and this agreement only. We never use them for advertising. The Privacy Policy says how we handle that address.
