Zendat Terms of Service

Last updated: 29 October 2026

1. Who we are

Zendat is a sole proprietorship (eenmanszaak) established in the Netherlands.

  • Trade name: Zendat
  • Owner: Jason den Hartog, trading as Zendat
  • Chamber of Commerce (KVK) number: 42169110
  • Address: De Kriek 30, 3451 KK Vleuten, the Netherlands
  • VAT identification number: NL005552054B70
  • Email: support@zendat.eu
  • Website: zendat.eu

2. Definitions

  • Zendat, we, us: the provider named in section 1.
  • The app: the Zendat app for Shopify, which sends electronic invoices and credit notes over the Peppol network for orders placed in a Shopify shop.
  • Merchant, you: the business that installs the app in its Shopify shop. The app is offered to businesses only, not to consumers.
  • Buyer: a customer of the merchant who places an order and gives a VAT number.
  • Access Point: the certified Peppol access point through which Zendat hands documents to the Peppol network: E-invoice BV, trading as e-invoice.be, Brusselsesteenweg 119A, 1980 Zemst, Belgium, enterprise number BE 1018.265.814. Zendat sends through it as the merchant's mandate holder (section 8).
  • Document: an electronic invoice or credit note the app creates from an order or a refund and hands to the Access Point.
  • Shopify: Shopify International Limited, or the Shopify entity that contracts with the merchant, which runs the platform the app is installed on.

3. The service

3.1. The app builds an electronic invoice, in the Peppol BIS Billing 3.0 format (EN 16931), for an order in the merchant's shop for which a buyer has given a VAT number, has the Access Point check it against the Peppol rules, and, when the merchant sends it or has switched automatic sending on, hands it to the Access Point for delivery to the buyer's own access point over the Peppol network. For every refund of such an order the app creates a credit note in the same way, once the order's invoice has been delivered.

3.2. The buyer gives their VAT number in a block the merchant places on the shop's thank-you page and order status page. The app checks the number's format and, when the service is available, its validity with VIES, the European Commission's VAT information exchange system.

3.3. The app reads the order, the refund, the shop's details and the merchant's business entity from Shopify at the moment a document is built. The document names the merchant as supplier by the legal name and registered address of the merchant's primary business entity in Shopify, or, when Shopify offers none, by the shop's name and billing address; the app says on its settings page which of the two it would use.

3.4. The merchant's own VAT number and, if given, bank account number are entered by the merchant in the app and go on every document.

3.5. The app is provided as it is on the day it is used. We may change, extend or remove features. A change that removes a material part of the service will be announced in the app or by email at least 30 days before it takes effect.

3.6. Orders placed through a test payment gateway, or otherwise marked by Shopify as test orders, are never invoiced.

4. Installing and using the app

4.1. To use the app the merchant needs a Shopify shop, an installed copy of the app, and an account at the Access Point that Zendat sets up for the merchant (section 8). Until that account exists no document can be sent.

4.2. The merchant grants the app the access to its shop that Shopify asks for at installation: reading and writing orders, reading payment terms, and reading the buyer's name, email address and address on an order for the purpose of the invoice. The app never reads a buyer's phone number.

4.3. The merchant is responsible for everyone who uses the app under its Shopify account, and for keeping that account secure.

5. Fees

5.1. The app is billed through Shopify App Pricing. The price is shown on the plan selection page in Shopify before the merchant chooses a plan, and is, at the time of writing:

  • Standard: USD 14 per month, including 25 invoices sent per billing month; USD 0.29 for every further invoice sent in that month.
  • Pro: USD 49 per month, including 150 invoices sent per billing month; USD 0.27 for every further invoice sent in that month.
  • Business: USD 99 per month, including 400 invoices sent per billing month; USD 0.24 for every further invoice sent in that month.
  • Credit notes are not counted and not charged, on every plan.
  • A 14-day free trial on Standard, during which at most 25 invoices can be sent; the 26th is sent once the merchant has chosen a plan. Pro and Business have no trial. Trial days are counted by Shopify per merchant: a reinstall continues the trial where it was left, it does not restart it.

5.2. Charges are billed and collected by Shopify under the merchant's agreement with Shopify and appear on the merchant's Shopify bill. Zendat does not itself invoice the merchant for the app.

5.3. An invoice counts as sent, and is charged, when the Access Point has confirmed that it went out onto the Peppol network. An invoice the Access Point refused, one still waiting for that confirmation, or one that was held back by the app, is not charged. Whether the buyer's access point later accepted it does not change that.

5.4. Prices are in US dollars because Shopify App Pricing bills in US dollars. Shopify converts the charge to the merchant's billing currency at its own rate.

5.5. We may change the price with at least 30 days' notice through Shopify and in the app. Shopify asks the merchant to approve a changed price before it applies.

5.6. Refunds of fees are not given, except where the law requires it.

6. The merchant's responsibilities

6.1. The content of every document is the merchant's. The app builds documents from the data in the merchant's shop and from what the merchant and the buyer entered. Zendat only converts that data into a document and hands it over; beyond the checks of section 3, it does not check whether what a document says is right. The merchant is responsible for the correctness and completeness of that data, in particular:

  • its own VAT number, bank account number and business entity;
  • the products, prices, taxes and tax rates on its orders, and the tax settings of its shop;
  • the buyer's VAT number, which the app checks for format and, where VIES answers, for validity, but which the merchant remains responsible for accepting;
  • whether an order is one that should be invoiced over Peppol at all.

6.2. The merchant checks before sending. The app shows, before a document is sent by hand, who it goes to and what it says, and offers a check of any order against the Peppol rules at any time. Where the merchant switches automatic sending on, the merchant accepts that documents are sent for every paid order with a buyer's VAT number without anyone reading them first, and is responsible for the settings that make that happen.

6.3. Tax and legal compliance. Zendat is not a tax adviser, accountant or law firm. The merchant is responsible for whether its invoices meet the requirements of the tax law that applies to it, for invoice numbering, for archiving its invoices for the period the law requires, and for its obligations under Belgian or other electronic invoicing law. The app numbers invoices after the Shopify order number and credit notes after the order number and a sequence number; the merchant checks that this fits its own numbering obligations.

6.4. Archiving. Documents are held at the Access Point after they are sent (section 8.5). The merchant is responsible for keeping its own copy of every invoice and credit note for as long as the law requires, and can download the PDF of a document from the app while the app is installed.

6.5. The thank-you block. The merchant places the app's block on the thank-you page of its checkout, in Shopify's checkout editor. Without it no buyer can give a VAT number, and no order is invoiced. The app cannot see whether the block is placed.

6.6. The merchant uses the app only for its own shop and its own business, lawfully, and not to send documents that are false, misleading or not owed. The merchant does not use the app or the Access Point to send unsolicited documents or anything that amounts to spam; does not probe, scan or test the app or the Access Point for weaknesses, or interfere with their working; and does not send anything that carries malware or other harmful code.

7. Sending, and what cannot be undone

7.1. A document handed to the Peppol network cannot be recalled, corrected or withdrawn. The app says so before every send and refuses to send the same document twice. Once the Access Point has accepted a document, neither the merchant nor Zendat can take it back. A wrong invoice is corrected the way the law provides for it, by a credit note and, where needed, a new invoice, which the merchant issues.

7.2. The app hands a document to the Access Point; the Access Point delivers it to the buyer's access point; the buyer's access point delivers it to the buyer. Zendat's part ends when the Access Point has accepted the document. The app records what the Access Point reports about delivery, and the merchant can ask the Access Point through the app where a document stands, but Zendat does not warrant delivery to, or receipt by, the buyer.

7.3. Where the buyer is not registered on the Peppol network the app warns the merchant and never sends the document automatically; the merchant can still send it by hand.

7.4. Automatic sending, when the merchant switches it on, looks at every paid order half an hour after it is paid, or as soon as a VAT number is saved on it, and sends an invoice when the order passes the app's checks. Orders without a VAT number are passed over. What became of every order is shown in the app. The merchant can switch automatic sending off at any time; that stops later orders, not a document already handed over.

8. The account at the Access Point, and the mandate

8.1. To send documents over Peppol the merchant needs an account at the Access Point. Zendat sets it up for the merchant, in the merchant's name, when the merchant connects the app. The account is for sending only: Zendat does not register the merchant on the Peppol network as a receiver of documents, so the merchant's Peppol identifier is not published there by Zendat, and the merchant does not receive documents through the Access Point. Today Zendat sets the account up once the merchant has signed the mandate of section 8.2 in the app; a later version of the app will set it up on its own at that moment.

8.2. By connecting the app the merchant authorises Zendat, and through Zendat the Access Point, to:

  • create and hold an account at the Access Point in the merchant's name;
  • send documents on the merchant's behalf, as the merchant's mandate holder, on the merchant's instruction given through the app;
  • receive delivery reports about those documents.

The merchant gives this authorisation in a mandate signed by a person entitled to represent it, as the Access Point requires of every company Zendat represents. For that mandate the merchant gives Zendat its company name, its VAT or enterprise number, an email address, a phone number, the name of the person signing and the name of its representative; keeps that information accurate; and tells Zendat of a change in it or in the merchant's legal status. Zendat hands the mandate and that information to the Access Point only when the Access Point asks for them.

8.3. Because Zendat registers nothing on the Peppol network for the merchant, a registration the merchant already has with another access point, for receiving documents, is not touched and does not stand in the way of sending through Zendat.

8.4. The Access Point does not suspend an account Zendat holds for a merchant for inactivity. It may suspend one under its own terms for a breach of those terms, a suspected unlawful use, a request from an authority, or non-payment. Zendat tells the merchant when its account is suspended and what is needed to restore it.

8.5. Documents sent through the account are held by the Access Point for as long as the account exists, and for one month after the account is closed, during which they can still be exported. After that month the Access Point may delete them. The merchant keeps its own copy (section 6.4).

8.6. When the merchant uninstalls the app, Zendat revokes the app's key to the merchant's account at the Access Point at once, and closes the account forty-eight hours later, when Shopify tells the app the shop's data may be erased. From that moment the documents can be exported for one month (section 8.5): the merchant asks support@zendat.eu within that month, or downloads the PDFs it wants to keep before uninstalling (section 13.4).

9. Availability

9.1. Zendat aims to keep the app available at all times but does not guarantee uninterrupted or error-free operation. The app depends on Shopify, on the Access Point, on the Peppol network, on VIES and on Zendat's hosting provider, none of which Zendat controls. When one of them is unavailable the app holds documents back rather than sending something uncertain, and tries again later; an order that could not be sent within the app's retry period is shown to the merchant to deal with. The Access Point provides its services as they are and as available, and neither Zendat nor the Access Point warrants that they are free of errors or fit for a particular purpose beyond what these terms say.

9.2. Zendat may suspend the app for maintenance, security or to comply with the law, and will announce planned maintenance where it can.

9.3. Zendat may suspend or end the merchant's use of the app when the merchant breaks these terms, when Shopify or the Access Point suspends or ends the merchant's account or its services to the merchant, or when the law requires it.

10. Liability

10.1. The app is a tool. Zendat is not a party to the merchant's contract with its buyers, does not issue invoices in its own name and is not the supplier on any document.

10.2. Zendat is not liable for damage that results from incorrect, incomplete or late data in the merchant's shop or entered by the merchant or a buyer; from a document the merchant sent, or had sent automatically, that it should not have sent; from the unavailability or conduct of Shopify, the Access Point, the Peppol network, VIES, the buyer's access point or Zendat's hosting provider; or from the merchant's tax, accounting or archiving obligations.

10.3. To the extent permitted by law Zendat is not liable for indirect or consequential damage, including lost profit, lost revenue, lost data, fines, tax assessments and claims by third parties.

10.4. Zendat's total liability towards the merchant, for all claims together, is limited to the fees the merchant paid for the app in the twelve months before the event that caused the damage, or EUR 250 if that is more.

10.5. Nothing in these terms limits liability for intent or deliberate recklessness, or for anything that cannot be limited by law.

10.6. The merchant indemnifies Zendat and the Access Point against claims by buyers, authorities or other third parties that arise from the content of the merchant's documents, from the merchant's use of the app or of the Access Point's services in breach of these terms, or from information the merchant gave for its account or its mandate being wrong.

10.7. Sections 9.1 and 10.1 to 10.6 apply equally for the benefit of the Access Point and its affiliates, licensors, service providers, employees, agents, officers and directors, with which the merchant has no contract of its own and which may rely on these terms towards the merchant. Towards the Access Point the limit of section 10.4 is EUR 100, since the merchant pays it no fees.

11. Personal data

11.1. How Zendat handles personal data is described in the Zendat Privacy Policy at https://zendat.eu/privacy/, which is part of these terms.

11.2. For the buyers' data the app processes to build documents, the merchant is the controller and Zendat is its processor under the GDPR. The data processing terms in Annex 1 to these terms apply; the merchant accepts them by installing the app.

12. Intellectual property

12.1. The app, its code, texts and design are Zendat's. The merchant gets a non-exclusive, non-transferable right to use the app for its own shop for as long as it is installed and paid for.

12.2. The documents the app creates belong to the merchant.

12.3. The merchant allows Zendat to read the data in its shop that the app needs for the service, and no more.

12.4. The Access Point's platform, through which documents are checked and delivered, belongs to E-invoice BV and is protected by its intellectual property rights. The merchant gets no right in it beyond the use the app makes of it on the merchant's behalf, and does not copy, resell or exploit any part of it.

12.5. The documents and data the app hands to the Access Point stay the merchant's (section 12.2). Under E-invoice BV's own terms the Access Point may use that data in an anonymised and aggregated form, in which no merchant, buyer or document can be identified, to analyse and improve its services; the merchant accepts this by connecting the app.

13. Term and ending

13.1. These terms apply from the moment the merchant installs the app until it uninstalls it.

13.2. Ending the agreement is done by uninstalling the app in Shopify. Shopify then stops billing at the end of the current billing period under its own rules. There is no notice period on the merchant's side.

13.3. On uninstalling: the app stops sending, cancels orders still waiting to be invoiced and switches automatic sending off. What happens to the merchant's data is described in the privacy policy: Shopify's access token is deleted at once, and forty-eight hours later, when Shopify tells the app the shop's data may be erased, the app erases everything about the shop except a minimal record per sent document (shop, order, document id, state and dates), which stops a reinstall from sending a second document for an order that already has one, and its own record of what it billed.

13.4. Documents already sent are not affected by uninstalling. The merchant downloads the PDFs it wants to keep before uninstalling; after that they can be had by asking support@zendat.eu within one month of the account being closed (section 8.6), and no longer once the Access Point has deleted them.

13.5. Zendat may end the agreement with 30 days' notice, and without notice in the cases of section 9.3.

14. Changes to these terms

14.1. Zendat may change these terms. Changes are announced in the app or by email to the shop's contact address at least 30 days before they apply, except changes required by law or by Shopify, which apply when they must. A merchant who does not accept a change uninstalls the app before it applies.

15. Other

15.1. Where a provision of these terms is void or voidable, the rest stands, and the provision is replaced by one that comes closest to its purpose.

15.2. The merchant may not transfer its rights under these terms without Zendat's consent. Zendat may transfer the agreement to a successor of its business, and will announce it.

15.3. These terms are in English. A Dutch or French translation may be offered for convenience; the English text prevails.

16. Law and disputes

16.1. Dutch law applies to these terms and to every agreement with Zendat about the app. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

16.2. Disputes are brought before the court competent for the district in which Zendat has its seat, in the Netherlands, unless mandatory law provides otherwise. Before going to court the parties try to settle the dispute between themselves within thirty days of one of them raising it in writing.
