Terms & Conditions

Version 4.0 dated March 17, 2026

§ 1 Scope of Application

  1. These General Terms and Conditions (GTC) apply to the use of the "Easy Invoices" app (hereinafter "App") by A&C Finance Solutions GbR, authorized representatives: Erik Arens & Jan Carl Werner Cwiklinski, address: Bamenohler Str. 34, 57413 Finnentrop, kontakt@a-and-c.de (hereinafter referred to as "Provider") and the users of the App (hereinafter "Users").
  2. The App serves to automate accounting processes and fulfillment processes and is distributed in the Shopify Store.
  3. Users of the App can exclusively be entrepreneurs within the meaning of § 14 BGB.
  4. By using the App, users agree to these GTC.

§ 2 Description of the App and its Functions

  1. The App supports shop operators in the automated creation of invoices, cancellation invoices, and credit notes, as well as in the partial automation of their accounting. This includes in particular the automatic recording and processing of order data, the generation and sending of invoice documents to customers, the management of cancellations and credit notes, as well as the integration of these processes into existing accounting systems. By automating these tasks, the administrative burden for shop operators is to be reduced and the efficiency of accounting processes increased.
  2. The App is offered through the Shopify App Store. Shop operators can install the App directly through the Shopify App Store and integrate it into their existing Shopify shops. The installation and use of the App is done through the shop operator's existing Shopify account.
  3. The availability and functionality of the App are based on the specifications and pricing models indicated in the Shopify App Store.

§ 2a No Tax or Legal Advice

  1. The functions, templates, and reports provided by the Easy-Invoices app do not constitute tax, legal, or business advice.
  2. Using the app does not replace consultation with a tax advisor or lawyer.
  3. Responsibility for the content, legal, and tax accuracy of generated invoices, bookings, and reports lies solely with the user.

§ 3 Registration and Use

  1. No registration is required to use the App. Access to the App is through the user's Shopify account.
  2. Use of the App requires a stable internet connection of the user's device. The user is responsible for this. Use of the App also requires prior consent to grant access rights by the user. Use is not possible without granting these consents.
  3. The Provider is entitled to change, further develop and improve the App technically and in terms of content at any time in a manner reasonable for the user.

§ 3a App Availability

  1. The Provider strives for high availability of the App. However, continuous availability is not guaranteed.
  2. The Provider is entitled to perform maintenance work that may lead to temporary restrictions or interruptions.
  3. The Provider is not liable for failures or disruptions that are beyond its control (e.g., force majeure, server failures, network disruptions).

§ 4 Contract Term and Termination

  1. Use of the App is as a monthly cancellable subscription through the Shopify App Store. By installing and activating the App, the user enters into a subscription that automatically renews for one additional month each time, unless it is cancelled within the cancellation period.
  2. Users can cancel the subscription at any time directly in the Shopify admin area. Cancellation can be made without stating reasons and becomes effective at the end of the current billing period. The cancellation periods are based on Shopify standards, which provide for a monthly billing cycle. Cancellation must occur at least one day before the end of the current billing period to prevent automatic renewal for an additional month.
  3. After cancellation of the subscription, access to the App and associated services will be deactivated at the end of the current billing period. The user has no claim to a refund of fees already paid for the current billing period. Any open invoices and documents should be downloaded and secured before the subscription expires, as access after deactivation of the App is no longer possible.
  4. The Provider reserves the right to terminate the subscription extraordinarily for important reasons. An important reason exists in particular if the user violates essential contractual obligations, uses the App abusively, or violates legal provisions. In such a case, termination occurs without observing a notice period and access to the App is immediately deactivated.

§ 5 Prerequisites for Use

  1. An internet browser (e.g., Chrome, Firefox, Safari, Edge) is required to use the App.
  2. Use of the App is only possible for Shopify shops. Use is tied to a Shopify account.
  3. A stable internet connection is recommended for synchronization, reporting, and real-time functions.

§ 6 Prohibition of Misuse

  1. The user is prohibited from using the App for illegal transactions. The user commits to not taking any actions that violate the rights of third parties.
  2. In case of a violation of third-party rights, the user indemnifies the Provider upon first request from all claims of third parties. This also includes the costs of legal defense and prosecution.

§ 6a User Cooperation Obligations

  1. The user is obliged to provide all information required for using the App completely, correctly, and up-to-date.
  2. The user is solely responsible for the content accuracy of entered data, especially invoice, tax, and accounting information.
  3. The user is responsible for creating backups of their data. The Provider assumes no liability for damages resulting from incorrect entries or omitted data backups by the user.

§ 7 Payment Processing

  1. Payment processing is handled by Shopify directly through the user's Shopify account. The Provider has no direct access to users' payment information and therefore assumes no responsibility for the security and confidentiality of payment data processed in the course of transactions.
  2. The Provider expressly points out that all refund claims and complaints regarding payment processing must be directed directly to Shopify. The General Terms and Conditions / Terms of Use of Shopify, which the user has accepted when using, apply in this regard. The Provider assumes no liability for any refunds or other claims in connection with payment processing by Shopify. It is the user's responsibility to inform themselves about Shopify's respective refund conditions and processes and to observe them.
  3. The Provider assumes no responsibility for any additional costs that may arise for the user through the use of a particular payment method, such as transaction fees, currency conversion fees, or other costs charged by Shopify or the payment service provider. It is the user's responsibility to inform themselves about such additional costs in advance and to take them into account.
  4. If the customer exceeds the maximum number of invoices included in their booked plan within a billing period, the additional costs/conditions listed on the Overage Pricing page shall apply for each invoice exceeding the respective limit. These overage terms are part of this contract and may be adjusted by the Provider for objective reasons with future effect, provided that no essential contractual obligations are changed to the detriment of the customer.

§ 7a Overage Charges for Exceeding the Booked Invoice Limit

  1. If the customer creates more invoices within a billing period in their Shopify online store than the maximum invoice limit set in their booked plan, the Provider is entitled to charge additional fees for each invoice exceeding this limit.
  2. Overage charges are billed automatically through the Shopify billing system ("Shopify Billing") used by the Provider and are invoiced to the customer through their Shopify account. By booking the respective plan, the customer expressly agrees to this billing method.
  3. The customer is responsible for independently monitoring their booked invoice limit. There is no automatic cap on the number of invoices created.
  4. Unless otherwise individually agreed, the overage charges per plan as listed on the Overage Pricing page shall apply. All prices are exclusive of applicable statutory value-added tax. The billing period is one calendar month.
  5. Overage charges are billed exclusively through Shopify's billing system in US Dollars (USD). The Provider has no influence on the exchange rate used by Shopify. Any exchange rate-related costs or reduced revenues are borne by the customer, as are any conversion fees and bank surcharges. The amount ultimately charged to the customer in their local currency may therefore differ from the reference price stated in US Dollars (USD). The customer agrees to this billing method and the resulting possible deviations.

§ 7b Adjustment of Plan Prices

  1. The Provider is entitled to adjust the plan prices stated in these GTC or in connection with the use of the "Easy Invoices" app at any time. This includes in particular changes to prices for existing plans and pricing tiers.
  2. Price changes will be communicated to the user at least 30 days before they take effect in text form (e.g., by email or in-app notification).
  3. If the user does not accept the changed prices, they have the right to terminate the user agreement at the time the price change takes effect. The termination must be made in text form and submitted by the time the price change takes effect. The previous prices shall continue to apply until termination of the contract.
  4. Price changes may be made in particular due to increased operating costs, changes in external procurement or processing costs, legal or tax changes, as well as other economic developments.

§ 8 Limitation of Liability

  1. The Provider is liable without limitation in cases of intent and gross negligence.
  2. In cases of simple negligence, the Provider is only liable for breach of essential contractual obligations (cardinal obligations) and limited to the typical, foreseeable damage.
  3. Liability is limited in amount to the sum the customer has paid to the Provider in the last 12 months before the occurrence of the damage event, but at most to €500,000 per damage event.
  4. Liability for lost profits, indirect damages, and consequential damages is excluded to the extent legally permissible.
  5. Essential contractual obligations are those whose fulfillment first enables the proper execution of the contract and on whose compliance the contracting party may regularly rely.
  6. In case of data loss, the Provider is only liable for such damage that would have occurred even with proper and regular, risk-appropriate data backup by the user.
  7. Unless expressly agreed otherwise, claims of the user from warranty and damages, with the exception of claims from tort, become statute-barred within the statutory limitation period.

§ 8a Software Defects

  1. The Provider does not guarantee error-free software, but rather its suitability for the contractually agreed purpose.
  2. The user must notify the Provider of defects immediately in text form.
  3. The Provider is entitled to remedy the defect or provide a replacement service at its own discretion.
  4. If defect remediation fails, the user may terminate the contract.

§ 8b No Guarantee of Success

  1. The Provider does not guarantee any specific economic or tax results.
  2. In particular, the Provider does not guarantee that the use of the App will achieve specific revenues, savings, or tax results.

§ 9 Data Protection / Data Processing Agreement

  1. The Provider processes personal data exclusively within the framework of legal provisions and the privacy policy.
  2. The user is the controller within the meaning of GDPR for the personal data they enter.
  3. Where necessary, a data processing agreement in accordance with Art. 28 GDPR will be concluded.
  4. Data is only passed on to third parties if this is necessary for contract processing or the user has expressly consented.
  5. Otherwise, the Provider's separate data protection provisions apply at https://easy-invoices.de/datenschutz.

§ 10 Intellectual Property Rights

  1. The Provider reserves all rights, in particular copyrights and trademark rights, to the App and all content provided within the App.
  2. The user acquires with the App a license limited in time to the duration of the installation, non-exclusive and non-transferable, to install and use the App on any compatible device of which they are the owner. The right of use also includes any updates (upgrades, patches, etc.).
  3. The user acquires a simple and non-transferable right of use to the content retrieved in the App. The right of use entitles the user to use the App and consume its content. It is limited in time to the agreed usage duration for the respective content. In particular, the right of use to old versions of content ends in the case of subscriptions with the end of the subscription.
  4. The user is not permitted to decompile, reverse engineer, disassemble, attempt to derive the source code, decrypt, modify the source code, or create derivative works of the App or its content or reuse them in other software. This does not affect the mandatory legal provisions according to § 69a ff. UrhG.

§ 11 Data Processing Agreement (DPA)

  1. Before using the App, the conclusion of a Data Processing Agreement (DPA) in accordance with Art. 28 GDPR is required. Acceptance of the DPA takes place electronically during the app's onboarding process.
  2. The DPA governs the processing of personal data of the user's end customers by the Provider in the course of using the App.
  3. The current DPA can be downloaded as a PDF document at any time via the app's settings page.
  4. Further information on data processing and the sub-processors used can be found in the Privacy Policy.

§ 12 Final Provisions

  1. The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods.
  2. If the user is a merchant, legal entity under public law or special fund under public law, the exclusive place of jurisdiction for all disputes arising from this contract is the seat of the Provider.
  3. Should individual provisions of these GTC be or become wholly or partially invalid, the validity of the remaining provisions remains unaffected. The statutory provisions shall take the place of the invalid provision.
