We may delete or archive data after account closure, expiry, inactivity or termination, subject to legal and operational retention requirements.

14. Service Availability

We aim to provide a reliable service, but we do not guarantee uninterrupted, error-free or always-available access. The service may be affected by maintenance, updates, hosting issues, third-party failures, HMRC downtime, internet disruption or security events.

15. Third-Party Services

The service may depend on third-party providers, including hosting providers, payment providers, email providers, analytics providers, HMRC and other API services. We are not responsible for failures, outages, changes or decisions made by third-party providers.

16. Fees and Payments

Some features may be free and others may require payment. Where paid plans are offered, pricing, billing periods, renewal rules and cancellation options will be shown before purchase or in the user account area.

You are responsible for all fees, taxes and charges associated with your use of paid services, unless otherwise stated.

17. Refunds and Cancellation

Refunds, where applicable, will be handled according to the plan terms, applicable consumer law and any written agreement between you and us.

Business users acknowledge that access to digital services may begin immediately after purchase or activation.

18. Intellectual Property

The service, website, software, design, code, branding, documentation and related materials are owned by us or our licensors. You may use the service only as permitted by these Terms.

You retain ownership of your business data, invoice data and content entered into the service. You grant us a limited right to process that data only as needed to provide, secure, support, improve and operate the service.

19. Confidentiality

Each party should keep confidential information received from the other party confidential, except where disclosure is required by law, regulation, court order, HMRC, professional advisers or necessary service providers.

We may suspend or terminate access if:

• payment is overdue;
• we suspect fraud, security risk or unauthorised access;
• we are required to do so by law, HMRC, a regulator or a third-party provider;
• continued access could harm us, other users or the service.

You may stop using the service at any time. Account closure does not remove obligations that already arose before closure.

21. Disclaimers

To the maximum extent permitted by law, the service is provided on an “as is” and “as available” basis. We do not guarantee that the service will meet every requirement, that calculations will always be correct for every tax scenario, or that HMRC submissions will always be accepted.

You must independently verify important accounting, tax and legal information before relying on it.

22. Limitation of Liability

Nothing in these Terms limits or excludes liability where it would be unlawful to do so, including liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation, or any rights that cannot be excluded under applicable law.

• loss of anticipated savings;
• loss or corruption of data where you failed to keep adequate backups;
• tax penalties caused by inaccurate or late information supplied by you;

• HMRC downtime, rejection, API changes or third-party service failures.

For paid services, our total aggregate liability arising out of or relating to the service will be limited to the amount you paid to us for the service in the 12 months before the event giving rise to the claim, unless applicable law requires otherwise.

For free services, beta services, sandbox features or test environments, our liability is limited to the maximum extent permitted by law.

You agree to indemnify and hold us harmless from claims, losses, damages, penalties, costs and expenses arising from your misuse of the service, unlawful data entry, unauthorised HMRC access, false tax submissions, breach of these Terms, or infringement of third-party rights.

24. Beta, Sandbox and Test Features

Some features may be provided for testing, sandbox, trial or beta purposes. Such features may be incomplete, contain errors, change without notice or be withdrawn. You must not rely on sandbox or beta features for live tax obligations unless we expressly state that they are production-ready.

25. Changes to the Service

We may modify, update, suspend, replace or discontinue parts of the service from time to time, including to improve functionality, comply with HMRC/API changes, enhance security or meet legal requirements.

26. Changes to These Terms

We may update these Terms from time to time. Updated Terms will be posted on this page with a revised “Last updated” date. Continued use of the service after updates means you accept the updated Terms.

27. Force Majeure

We are not responsible for delay or failure caused by events beyond our reasonable control, including internet failures, cyberattacks, hosting outages, power failures, labour disputes, legal changes, HMRC outages, API changes, natural disasters, war, terrorism or government action.

You may not transfer your rights or obligations under these Terms without our written consent. We may transfer our rights or obligations as part of a business transfer, restructuring, merger, sale or legal reorganisation.

29. Severability

If any part of these Terms is found invalid or unenforceable, the remaining parts will continue in effect.

30. No Waiver

If we do not enforce a right immediately, that does not mean we waive that right.
