Doorst.app — Terms of Service (Algemene Voorwaarden)

Version: 1.1 — Last updated: 18 August 2026 — Effective date: 18 August 2026

These Terms replace version 1.0 of 23 June 2026. If you subscribed before the effective date above, any change that materially affects your rights takes effect for you 30 days after we notify you, as described in Section 29.

1. Who we are and what these terms cover

These Terms of Service ("Terms") govern your use of Doorst.app ("Doorst", the "Service"), operated by BTNG B.V., KvK 91214777, BTW NL865584047B01, registered at Willem Roelofsstraat 3, 7424 GD Deventer, The Netherlands ("we", "us"). By creating an account or using the Service, you ("you", the "Agency", "Customer") agree to these Terms. If you do not agree, do not use the Service.

These Terms are our general terms and conditions (algemene voorwaarden). They are made available to you electronically before you subscribe, on this page, in a form you can save and print. On request we will send you a copy by email at no charge.

Your own terms do not apply. Any purchase conditions or general terms of your own are expressly rejected and do not apply to this agreement, even if we do not object to them at the time (Article 6:225(3) of the Dutch Civil Code).

Language. These Terms are written in English. If we publish a translation and the two versions differ, the English version governs.

2. Definitions

  • Service — the Doorst.app software, the marketing site at doorst.app, the application at app.doorst.app, and each agency environment at {agency}.doorst.app or a custom domain.
  • Workspace — your agency environment inside Doorst, including your team members, clients, plans, invoices and tasks.
  • Your Data — everything you or your clients put into your Workspace: client records, subscriptions, plans, tasks, comments and uploaded files.
  • Client — a business you serve and manage through Doorst. Your clients are not parties to these Terms.
  • Invoicing Provider — Moneybird, Mollie or Stripe, connected by you and used by Doorst to issue invoices to your clients.
  • DPA — our Data Processing Agreement (verwerkersovereenkomst).

3. The Service

Doorst is a subscription-management tool for productized agencies. It lets an agency manage client subscriptions, issue invoices through a connected Invoicing Provider (Moneybird, Mollie or Stripe), run a branded client portal, and manage the work in a task board. Doorst is a tool: we provide the software; you are responsible for how you use it and for your relationship with your own clients.

Doorst does not hold, receive or move your clients' money. Payments from your clients flow through the Invoicing Provider you connect, under your own account and your own agreement with that provider.

4. Who may use Doorst (B2B only)

Doorst is offered to businesses only (agencies and other professional users acting in the course of their business). It is not intended for consumers.

Because Doorst is a business-to-business service, the statutory 14-day right of withdrawal for consumers (herroepingsrecht / cooling-off period) does not apply to your subscription. If we ever offer the Service to consumers or sole traders acting as consumers, the applicable consumer-protection rules (including cooling-off and pre-contract information duties) will apply to those customers.

5. Accounts

You must provide accurate account information and keep your login credentials secure. You are responsible for everything done under your account, including by your team members and by anyone you invite. Tell us promptly at support@doorst.app if you suspect unauthorised use.

Accounts are for named people. Do not share one login between several people; invite them as team members instead. Team members are included on every plan at no extra cost.

6. Plans, tiers, limits and fair use

Doorst is offered in tiers. Each tier sets how many active clients you may manage:

  • Solo — 1 active client
  • Studio — up to 15 active clients
  • Agency — unlimited active clients

Current plans, prices, limits and included features are shown on the pricing page at the time you subscribe. Section 9 explains how price changes work, and Section 10 covers the founding-customer exception.

Reaching a limit never removes anything. If you hit your tier's client limit, we block adding or reactivating a client until you upgrade; clients you already have stay exactly as they are.

Fair use of "unlimited". Where a plan is described as unlimited (active clients, team members, storage), that means no fixed cap in normal professional use. It does not permit use that is plainly outside that pattern — for example resale of your workspace to unrelated businesses, automated bulk creation of records, or storage unconnected to your client work. If your use reaches that point we will contact you first and agree a reasonable arrangement before taking any other step.

7. Free trial

We currently offer a 14-day free trial on signup. No payment is taken during the trial, and the trial carries no client limit.

Unless the signup page says otherwise, the trial does not convert automatically into a paid subscription: at the end of the trial your workspace pauses until you choose a plan. If we ever change that, the terms shown at signup will say so plainly before you start.

8. Subscriptions, billing and renewal

Billing cycle. Subscriptions are billed in advance on a recurring basis (monthly or annually, as you select). Prices are per workspace, not per user.

Auto-renewal. Subscriptions renew automatically at the end of each billing period at the then-current rate for your plan (subject to Section 10 for founding customers), until you cancel. By subscribing you authorise these recurring charges, including by SEPA direct debit where you set up a mandate.

Payment provider. Payments to us are processed by Mollie (iDEAL, SEPA direct debit, and/or card, depending on what is offered). Card and bank details are entered with and held by Mollie, not by us. Mollie's own terms apply to the payment transaction itself. This is separate from the Invoicing Provider you connect to bill your own clients.

VAT / BTW. Prices are stated excluding VAT unless marked otherwise. We charge Dutch VAT (currently 21%) where applicable. For business customers established in another EU country who provide a valid VAT identification number, we apply the EU reverse-charge mechanism (0% VAT, "BTW verlegd"), provided the number validates against the EU VIES system. You are responsible for the validity of the VAT number you provide and for accounting for VAT in your own country where reverse charge applies. If a number cannot be validated, we may charge VAT until it is.

Failed payments. If a payment fails, we may retry it and send reminders (dunning). If payment is not completed within the grace period we set, we may suspend your access until the outstanding amount is paid. Continued non-payment may lead to termination under Section 14.

Late payment. Where an amount remains unpaid after the due date, we may charge the Dutch statutory commercial interest (wettelijke handelsrente, Article 6:119a of the Dutch Civil Code) and reasonable extrajudicial collection costs, with a minimum of €40, in line with Directive 2011/7/EU on late payment in commercial transactions.

9. Price changes

We may change the price of a plan for future billing periods. We will give you at least 30 days' notice by email before a change takes effect on your subscription. If you do not accept a price increase, you may cancel before it takes effect under Section 11, and the increase will not be charged to you. Continued use after the change takes effect means you accept the new price. Founding customers are protected from price increases as set out in Section 10.

10. Founding-customer offer (the first 100, lifetime discount)

The first 100 paying customers of Doorst receive a lifetime discount on their Doorst platform subscription. The size of the discount depends on how early you join:

  • The first 25 — 60% off, locked for life.
  • Customers 26 to 100 — 30% off, locked for life.
  • From customer 101 — the standard price applies.

How your place is counted. A place is taken when your first invoice is issued for a paid platform subscription. Trials do not take a place. If that invoice cannot be created, the place is released again, so a failed signup never burns one.

Lifetime lock. Your discount applies for as long as your subscription remains continuously active. While you stay on the plan you joined on, the euro amount you pay is frozen: if we later raise the standard price of that plan, your amount does not move.

Changing plans. If you switch plans, your locked percentage carries over and applies to the new plan's current price. Upgrading does not cost you your founding status.

Stacking with the yearly discount. Where we offer a discount for paying annually, the founding discount and the yearly discount stack.

Closing. Each band closes when it is full, and the offer as a whole closes once 100 places are taken. Which band is open, and how many places remain, is shown on the pricing page.

Cancelling means losing it. The founding rate is tied to your continuous subscription. If you cancel you lose it. If you later resubscribe you do so at the standard price then in force; the founding rate is not restored, and if all 100 places are taken the offer is no longer available.

We reflect your founding status and locked rate in your billing settings.

11. Cancellation and refunds

You can cancel at any time from your account settings, without giving a reason and without a cancellation fee. Cancellation takes effect at the end of the current billing period — you keep access until then, and your subscription does not renew for the next period.

We do not give partial refunds for the unused part of a billing period, except where required by law or where we cancel your subscription for a reason that is not attributable to you. Amounts already paid for the current period are not refunded on cancellation.

On cancellation, your account moves to a limited state as described in Section 12. See also Section 10 for the effect of cancellation on the founding rate, and Section 13 for getting your data out.

12. What happens when a subscription ends or lapses

If you cancel, or if your subscription is suspended for non-payment, we may place your account into a read-only / limited state: you keep access to your existing data and can reactivate or upgrade, but you may be blocked from adding new clients or creating new work until the subscription is active again.

Where your own clients use a portal provided through Doorst, those clients may see a neutral message asking them to contact you (the agency) about their dashboard. We aim to do this in a way that does not expose your billing status to your clients, but you remain responsible for your relationship with them.

We keep your data available in that state for at least 30 days after the subscription ends, so you can export it or reactivate. After that period we may delete it, in line with Section 13 and our Privacy Policy.

13. Switching, export and exit

Your data is yours and we will not hold it hostage. This section sets out how you get it out, and reflects the switching and portability requirements for data processing services under Regulation (EU) 2023/2854 (the Data Act).

  • Notice to leave. You may terminate this agreement and switch to another provider or to your own systems at any time under Section 11. The maximum notice we require is the remainder of your current billing period, and never more than two months.
  • Transition period. After you tell us you are leaving, a transition period of up to 30 days applies, during which we keep your data retrievable and assist your switch. If a switch genuinely cannot be completed in 30 days, we will extend the period by a reasonable amount on request.
  • Export. During the transition period, on request to support@doorst.app, we provide an export of Your Data in a structured, commonly used, machine-readable format (JSON and/or CSV), together with your uploaded files. We aim to deliver it within 10 working days. If the app offers a self-service export at the time you ask, you can use that instead.
  • Assistance. We will give you the information you reasonably need to understand the export and move to another service, and we will act in good faith to make the switch work.
  • No exit fees. We do not charge switching charges, egress fees or export fees.
  • Erasure after exit. At the end of the transition period we erase Your Data, except what statutory retention obliges us to keep (see Section 12 of our Privacy Policy and the 7-year invoice-retention rule).

14. Suspension and termination

We may suspend or terminate your access if you materially breach these Terms, fail to pay, or use the Service unlawfully or in a way that harms the Service or others. Where reasonable and not urgent, we will give you notice and a chance to fix the problem first, and we will limit any suspension to what is necessary. You may terminate at any time by cancelling under Section 11.

If we terminate for a reason not attributable to you — for example if we discontinue the Service — we will give you at least 90 days' notice, refund the unused part of any prepaid period, and support your export under Section 13.

15. Acceptable use

You agree not to: use Doorst unlawfully or to process data you have no right to process; upload malware or unlawful content; attempt to breach security, rate limits or tenant isolation; access another agency's data; use the portal or invitation emails to send unsolicited bulk mail; resell or provide the Service to third parties except your own clients through the intended portal functionality; process special categories of personal data (Article 9 GDPR) without a separate written agreement with us; or use the Service in a way that overloads or disrupts it.

Security research. We welcome responsible disclosure. Do not test against other agencies' workspaces or real client data, and report anything you find to support@doorst.app before disclosing it publicly. We will not pursue good-faith researchers who follow that.

16. Your clients and your responsibilities

You are solely responsible for your own clients, your contracts with them, the content you upload, and the personal data you process through Doorst. As between you and us, you are the controller of your clients' personal data and we are your processor for that data. That processing is governed by our Data Processing Agreement (verwerkersovereenkomst), which forms part of these Terms where you process personal data through Doorst.

You are responsible for telling your clients and portal users what you do with their data, for having a lawful basis for it, and for the accuracy of what you enter. Where a client asks you to correct or erase their data, Doorst gives you the tools to do it.

17. Third-party services

Doorst connects to services you choose: Moneybird, Mollie or Stripe for invoicing your clients, and Mollie for paying us. Those connections run under your own account and your own agreement with that provider. We are not a party to those agreements and are not liable for a provider's acts, outages, fees or decisions, including a refusal to onboard you or a hold on your funds.

If a provider changes or withdraws an API we rely on, we will adapt the Service where reasonably possible and tell you if a connection can no longer be supported.

18. Intellectual property, your data and feedback

  • Your data is yours. You retain all rights to Your Data. You grant us the limited, non-exclusive rights needed to host, process, back up and display it in order to provide the Service, and to act as your processor under the DPA. We do not sell Your Data, we do not use it for advertising, and we do not use it to train artificial-intelligence models.
  • The software is ours. We retain all rights to the Doorst software, design, documentation and brand. These Terms transfer no ownership; you receive a limited, non-exclusive, non-transferable right to use the Service for the duration of your subscription.
  • Feedback. If you send us feedback, feature requests or bug reports (including through our in-app feedback tool), we may use them freely to improve the Service, without obligation or payment to you. We will not publish your feedback in a way that identifies you or your clients without your consent.

19. Confidentiality

Each party will keep the other's non-public information confidential, use it only for this agreement, and protect it with at least reasonable care. This does not apply to information that is public through no breach, was already lawfully known, or must be disclosed by law — in which case, where permitted, the disclosing party is told first. Your Data is always treated as your confidential information.

20. Availability, support and changes to the Service

We work to keep Doorst available and reliable, and we aim for high availability, but we do not commit to a specific uptime percentage unless a separate written service-level agreement says otherwise. Planned maintenance is scheduled outside Central European business hours where we can, and announced in advance where it is likely to be noticeable.

Support is by email at support@doorst.app. We aim to answer within one working day on Dutch working days. The Agency plan includes priority support as described on the pricing page.

Changes to the Service. We improve Doorst continuously and may add, change or remove features. We will not materially reduce the core functionality of your plan without at least 30 days' notice; if a change materially and negatively affects you, you may cancel under Section 11 and we will refund the unused part of any prepaid period.

Beta features. Features labelled beta, preview or experimental are provided as-is, may change or disappear, and are excluded from any availability or support commitment.

21. Security and incidents

We take appropriate technical and organisational measures to protect the Service and the data in it, as described in our Privacy Policy and in Annex 3 of the DPA.

If a security incident affects your workspace or the personal data we process for you, we will notify you without undue delay and give you the information you reasonably need to meet your own obligations under Articles 33 and 34 GDPR. Our notification obligations as processor are set out in the DPA.

22. Warranties

We provide the Service "as is" and do not guarantee uninterrupted or error-free operation. To the extent permitted by law, we disclaim implied warranties, including fitness for a particular purpose. We do warrant that we will provide the Service with reasonable skill and care, and that we have the right to grant the rights in these Terms.

Doorst is not accounting, tax or legal advice. You remain responsible for the correctness of your invoices, your VAT treatment and your bookkeeping, whatever the Service calculates or sends.

23. Liability

To the extent permitted by Dutch law, our total liability arising out of or relating to the Service in any 12-month period is limited to the amount you paid us for the Service in that period. We are not liable for indirect or consequential loss, including lost profits, lost revenue, lost goodwill, or loss of data beyond our obligation to maintain reasonable backups.

Nothing in these Terms excludes or limits liability that cannot be excluded under Dutch law, including liability for intent (opzet) or deliberate recklessness (bewuste roekeloosheid) on our part, or for death or personal injury.

A claim lapses unless you notify us of it in writing within 12 months of the date you became aware, or reasonably should have become aware, of the event giving rise to it.

24. Indemnity

You will indemnify us against third-party claims arising from your unlawful use of the Service or your breach of these Terms, including claims by your own clients or by data subjects relating to data you processed through Doorst.

25. Force majeure

Neither party is liable for failure to perform caused by circumstances beyond its reasonable control (overmacht), including failures of hosting, connectivity, payment or invoicing providers, cyber-attacks, power failures, government measures, or natural events. Payment obligations for the Service already provided are not suspended by this Section. If force majeure lasts longer than 60 days, either party may terminate the affected part of the agreement in writing.

26. Publicity

We may name you as a Doorst customer and use your logo on our website and in materials describing our customers. Tell us at support@doorst.app and we will stop and remove it. We will not disclose the details of your workspace, your clients or your pricing.

27. Assignment and subcontracting

You may not assign this agreement without our written consent, which we will not unreasonably withhold. We may assign it to a group company or in connection with a merger, acquisition or sale of assets, provided the acquirer assumes these Terms; where that involves personal data, the DPA and our Privacy Policy continue to apply and we will tell you in advance. We may use subcontractors and sub-processors to provide the Service, and we remain responsible for their performance; sub-processors are listed and governed under the DPA.

28. Notices

We send notices to the email address on your account, and they are deemed received on the day of sending. Keep that address current. You send notices to support@doorst.app, or by post to the address in Section 32. Notices about a personal-data matter may also go to privacy@doorst.app.

29. Changes to these Terms

We may change these Terms — for example to reflect new features, new sub-processors or changes in the law. We will post the updated version here with a new version number and "last updated" date. For changes that materially affect your rights or obligations, we will notify you by email at least 30 days before they take effect for your subscription. If you do not accept them, you may cancel under Section 11 before they take effect; continued use after that means you accept the updated Terms.

Purely editorial changes, and changes required by law with a shorter deadline, may take effect sooner. We keep the previous version available on request.

30. Miscellaneous

  • Severability. If any provision is held invalid or unenforceable, the rest stays in force and the invalid provision is replaced by a valid one that comes closest to its purpose.
  • No waiver. Not enforcing a right on one occasion does not waive it.
  • Entire agreement. These Terms, the DPA, the Privacy Policy, the Cookie Statement and the plan details shown at signup are the whole agreement between us on their subject, and replace earlier arrangements.
  • Order of precedence. If they conflict: the DPA on data processing, then these Terms, then the other documents.
  • Survival. Sections 13, 18, 19, 22, 23, 24, 30 and 31 survive termination.
  • Independent parties. Nothing here creates a partnership, agency relationship or employment between us.

31. Governing law and jurisdiction

These Terms are governed by Dutch law. We will try to resolve any dispute with you directly first. Failing that, disputes will be submitted to the competent Dutch court for the district of our registered office (Rechtbank Overijssel), unless mandatory law provides otherwise.
