Version 2.0 · Effective date: 31 October 2026 · Replaces: version dated 9 October 2026

1. About these terms

These Terms and Conditions (“Terms”) govern your access to and use of ukeinvoice.co.uk, including any page, form, readiness checker, download, guide, chat feature or online demo made available through it (the “Website”). By using the Website, you agree to these Terms. If you do not agree, please do not use the Website.

“UK eInvoice”, “Rishvi”, “we”, “us” and “our” mean Rishvi Ltd. “You” means the person using the Website and, where you use it on behalf of a business, that business. If you use the Website for a business, you confirm you have authority to accept these Terms for it.

2. Who we are

UK eInvoice is a service operated by Rishvi Ltd, a company registered in England and Wales, company number 08347225. Registered and operational address: Suite 1, 1st Floor, 730 Romford Road, London, Greater London, England, E12 6BT, United Kingdom. Email: info@rishvi.co.uk · Phone: +44 20 8050 3432. Rishvi Ltd also operates rishvi.co.uk, Linnworks Custom and HyperStock.

3. We are not HMRC or a Government body

Rishvi Ltd is an independent technology provider. It is not HMRC, the UK Government, a tax authority or a regulatory authority, and it is not endorsed by any of them. Nothing on the Website should be taken to suggest otherwise. References to HMRC, GOV.UK, Making Tax Digital or e-invoicing standards are for information only. Any Government logos, names or links remain the property of their owners.

4. Other terms that may apply

These Terms cover use of the Website only. Other documents apply to specific services:

• Paid services (including e-invoicing integration, readiness assessments, consultancy, software development, hosting and support) are governed by the applicable quotation, proposal, statement of work, client agreement or support order, together with Rishvi’s Standard Commercial Terms and Conditions and Commercial Engagement & Support Policy, in the versions incorporated into your agreement.
• Personal data is handled under our Privacy Policy and, where we process invoice or business data on your behalf, our Data Processing Agreement.
• Cookies are explained in our Cookie Policy.

Where any of those documents conflicts with these Terms, that document takes priority for its subject matter. Nothing on the Website changes a signed contract unless both parties agree in writing.

5. Business use

The Website and our services are intended for businesses and people acting in a business capacity. They are not intended for consumers or for anyone under 18.

6. Regulatory and tax information

• Content about UK e-invoicing, Making Tax Digital, VAT, invoice formats, standards and timetables is general business and technical information. It is not legal, tax, accounting or regulatory advice.
• Where we discuss future legislation or expected obligations, we aim to make clear whether it refers to law already in force, Government announcements, consultations, proposed dates or industry expectations. Requirements and dates can change, and content may not reflect the latest position.
• You should check official sources, such as GOV.UK and HMRC, and take professional advice on your own legal, tax and regulatory obligations before acting.
• Where we provide paid advice, its scope and any reliance on it are set out in the relevant agreement.

7. Readiness checks, tools and assessments

Any readiness checker, questionnaire, calculator or assessment on the Website gives an indicative result based on the information you enter. It does not guarantee that you are, or will be, compliant with any requirement. A full readiness assessment is a paid service agreed in writing.

8. Enquiries, consultations, quotes and proposals

• Information on the Website about our services, features, timescales or prices is general information and an invitation to contact us. It is not an offer that you can accept to form a contract.
• Submitting an enquiry or booking a call does not create a contract or oblige either of us to proceed.
• An initial discussion of up to 30 minutes is normally free and covers your requirements at a high level only. It does not include detailed troubleshooting, system review, solution architecture, implementation guidance or extended meetings. More detailed readiness assessments or technical discovery may be offered as a paid service, with the scope and fee agreed before work begins.
• A contract is formed only when both parties sign or expressly accept a written quotation, proposal, statement of work or client agreement. Quotes are valid only for the period stated on them, and an unaccepted quote does not reserve our staff or capacity.
• Unless a quote is expressly marked fixed price, quoted hours and costs are estimates. Prices exclude VAT unless stated otherwise.

9. What our services do and don’t do

• Our services help you create, validate, convert, send, receive and integrate electronic invoices with your systems. They support your processes; they do not take over your legal, tax or accounting responsibilities.
• We do not guarantee that a recipient, network, platform or authority will accept, process or pay any invoice.
• Validation checks, such as format, field or VAT-number checks, reduce errors but do not confirm that an invoice’s content or tax treatment is correct.
• Unless expressly agreed, we do not act as your agent before HMRC or any authority, submit tax returns, or provide statutory archiving.

10. Your responsibilities

When you use our services, you are responsible for:

• the accuracy and completeness of invoice data, customer and supplier details, and VAT and tax treatment;
• approving invoice templates, mappings and workflows before they go live;
• keeping your VAT and accounting records for the periods the law requires, unless we have expressly agreed to store them as part of the service;
• having authority to connect your ERP, accounting and other systems, and to share your trading partners’ data with us;
• managing your users and access, and removing access when people leave;
• providing timely information, test scenarios and decisions through an authorised contact; and
• taking your own legal and tax advice.

11. Credentials and secure access

Share passwords, API keys, certificates and tokens only through the secure method we agree with you, never by ordinary email, chat, WhatsApp or AI tools. We use access only for the agreed work and remove or disable it when it is no longer needed, subject to any agreed operational needs.

12. Third-party platforms and networks

E-invoicing networks and access points, Government services, ERP and accounting software, Linnworks, Odoo and other platforms are operated independently. We do not control their availability, standards, pricing, APIs or decisions. Adapting to their changes, or to changes in e-invoicing standards or legal requirements, may require separately agreed work unless a support plan covers it. Their own terms apply to your use of them.

13. Accuracy and availability of the Website

We aim to keep the Website accurate and up to date, but we do not guarantee that it is complete, current or free from error. We may update, suspend or withdraw any part of the Website at any time and do not guarantee that it will always be available.

14. Accounts, portals, demos and trials

Where the Website offers an account, client portal, demo or trial, you must give accurate information and keep your login details confidential. Demos and trials are provided “as is”, may have limited features and may end at any time. You must not use demo or trial environments for live invoices or real personal data unless we agree in writing.

15. Intellectual property

Unless stated otherwise, Rishvi Ltd or its licensors own the intellectual property in the Website and its content, including text, guides, graphics, code, logos and the UK eInvoice name. You may view and print content for your own business reference. You must not copy, republish, sell or create derivative works from it without our written permission, except where the law allows. Ownership of software and deliverables under a paid engagement is governed by your agreement and our Standard Commercial Terms.

16. Downloads, guides and templates

Guides, checklists, templates, sample files and code we make available are for your internal business use only, provided “as is” without warranty. Check them against current official guidance and test them before using them in live invoicing.

17. Information you send us

• You confirm that information you send through the Website is accurate and that you have the right to share it.
• Do not send real invoices, bank details, credentials or unnecessary personal data through website forms or chat. If we need them, we will agree a secure method.
• Do not upload anything unlawful, infringing or containing malware.
• We may use suggestions or feedback you give us to improve our services, without any obligation to you.

18. AI-generated content

Where any Website feature provides AI-generated information, it may be wrong, incomplete or out of date, especially about changing regulations. Verify it against official sources before relying on it. It is not professional advice and does not form part of any quote or contract.

19. Acceptable use

You must not:

• try to gain unauthorised access to the Website, our servers or any connected system;
• bypass or probe security features, or test for vulnerabilities without our written permission;
• introduce viruses, malware or other harmful code, or overload or disrupt the Website;
• use bots or automated tools to scrape content, including for AI training, in breach of our restrictions;
• impersonate any person or business, or suggest a connection with HMRC or the Government using our Website;
• send spam through our forms; or
• use the Website for any unlawful, fraudulent or harmful purpose, including invoice fraud.

We may suspend or block access and report activity to the authorities if we reasonably believe these Terms have been breached.

20. Security and vulnerability reporting

If you find a potential security vulnerability, please report it responsibly to info@rishvi.co.uk. Please do not access other people’s data, disrupt our services or disclose the issue publicly before we have had a reasonable chance to fix it.

21. Links to and from other websites

The Website may link to third-party websites, including GOV.UK and HMRC guidance. We are not responsible for their content, availability or privacy practices. You may link to our home page in a fair and lawful way that does not suggest any endorsement that does not exist. You must not frame the Website on another site.

22. Our liability

Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited by law.

Subject to that, and to any separate contract between us:

• the Website, its content, tools and downloads are provided “as is” and, to the extent permitted by law, we exclude all implied conditions, warranties and representations;
• we are not liable for any loss arising from your use of, or reliance on, general Website content, regulatory information, readiness tools or AI features, including tax penalties, rejected invoices or late payment; and
• we are not liable for any loss of profit, revenue, business, contracts, data or goodwill, or any indirect or consequential loss.

Liability for paid services is set out in the applicable client agreement.

23. Events outside our control

We are not responsible for delay or failure caused by events outside our reasonable control, such as failures of hosting or internet providers, e-invoicing networks or Government services, cyber attacks, power cuts or changes in law.

24. Privacy and cookies

How we use personal data is explained in our Privacy Policy. Cookies are explained in our Cookie Policy.

25. Changes to these Terms

We may update these Terms to reflect changes to the Website, our services, technology or the law. The version and effective date are shown at the top. Changes do not alter any signed contract.

26. General

• Severability: if any part of these Terms is unenforceable, the rest remains in force.
• No waiver: if we delay enforcing a right, we can still enforce it later.
• Transfer: we may transfer our rights and obligations under these Terms, for example as part of a business sale. You may not transfer yours without our written consent.
• Third parties: no one other than you and us may enforce these Terms under the Contracts (Rights of Third Parties) Act 1999.

27. Complaints

If you have a concern about the Website, please email info@rishvi.co.uk so we can try to resolve it. Complaints about a paid service are handled under the escalation process in the applicable client agreement.

28. Governing law

These Terms, and any dispute arising from them or from use of the Website, are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction, subject to any mandatory legal requirements.
