By using seisly.com you agree to these terms. If you do not agree, do not use the service.
1.1 Seisly is operated by Litigo Limited, a company incorporated in England and Wales (company number 16895608), registered at 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ (“Seisly”, “we”, “us”, “our”).
2.1 Our services are supplied to businesses. Our customers are companies, and the person placing an order is treated as acting for and on behalf of a company (typically the founder acting for their own startup). These terms are written on that basis. They are not consumer terms, and the Consumer Rights Act 2015 does not apply to them.
3.1 Seisly is a document preparation and application management service. We help companies prepare, and where requested submit, applications for SEIS and EIS advance assurance to HMRC. We serve UK companies and non-UK companies that qualify for UK SEIS/EIS.
3.2 Seisly is not a law firm, accountancy practice, or regulated financial services provider. We do not provide legal advice, tax advice, or investment advice. Nothing on seisly.com or in any document we prepare constitutes legal or tax advice.
3.3 If you need legal or tax advice, you should consult a qualified solicitor or accountant. Our free Seisly Advisers referral service can connect you with a vetted specialist firm; any engagement you enter into with that firm is a separate contract between you and the firm, on the firm's terms, and is not covered by these terms.
4.1 Our core product is the AA Draft. When you buy an AA Draft, you are paying for:
4.2 The following are optional paid add-ons, at the prices shown at checkout:
4.3 We also offer a free Eligibility Check before purchase, and the free Seisly Advisers referral service described at clause 3.3.
4.4 All prices are as stated on the pricing page at the time of purchase.
5.1 All prices are stated exclusive of VAT.
5.2 We are not currently registered for VAT and do not currently charge it, and we cannot issue a VAT invoice until we are registered. Prices shown as “+ VAT” indicate that VAT will be added once we are registered. We make the current VAT position clear at the point of sale.
5.3 Once our VAT registration takes effect, VAT at the prevailing rate applies to orders placed on or after the date registration takes effect. HMRC sets that effective date, which may be earlier than the date we receive our registration; where VAT becomes due on an order as a result, we may issue a VAT invoice for the VAT element, and from that point VAT invoices are available for qualifying orders.
5.4 Fees are payable at the point of order. Any refund is of the amount actually paid, in accordance with section 8.
6.1 Agent authority applies only if you purchase the Submission Service. When you do, the authority letter appointing Litigo Limited as your agent to submit your advance assurance application to HMRC is generated automatically and immediately when your payment is received.
6.2 This authority is limited to the specific advance assurance application you submit through Seisly. It does not give us authority to act for you in any other matter with HMRC.
6.3 The Submission Service is non-refundable from the time of purchase, as set out in section 8, save where we can provide no deliverable at all or where liability cannot lawfully be excluded.
7.1 You are responsible for:
7.2 Providing false or misleading information to HMRC is a criminal offence. We accept no liability for applications prepared or submitted on the basis of information you have provided that is inaccurate or incomplete.
8.1 The core principle. Our services involve work that we begin promptly after you order, and much of that work is automated and starts the moment your payment is received. Once work has begun on your order, the fee for that service is non-refundable, except where this section expressly says otherwise.
8.2 When work has begun. “Work has begun” means any one of the following has happened in relation to your order:
You should assume that work will start immediately after you order, and that for some services (see clause 8.7) there is no practical pre-work cancellation window at all.
8.3 Cancelling before work has begun. If you cancel within 24 hours of purchase and no work has begun, you are entitled to a full refund of the fee paid. Beyond 24 hours, or once work has begun (whichever is earlier), the fee is non-refundable, subject only to clauses 8.5, 8.6 and 8.7. To cancel, contact us at support@seisly.com quoting your order reference; cancellation takes effect when we receive your request.
8.4 Cancelling after work has begun. If you cancel after work has begun, the fee is non-refundable, whether or not you have yet received a deliverable, and whether or not you choose to use a deliverable you have received.
8.5 HMRC outcomes.
8.6 Where we cannot proceed. We may decline to proceed with any application at our discretion. If, after you have ordered, we determine that we can provide no deliverable at all for a service (for example, because we discover that you or your company does not qualify on grounds we could not reasonably detect at the eligibility-check stage), we will refund the fee in full for that service. Where we have already provided a deliverable for another service, only the service for which no deliverable was provided is refunded.
8.7 Product-specific terms.
8.8 How refunds are paid. Where a refund is due, we will make it to the original payment method unless that is not possible, in which case we will agree an alternative with you. We aim to process refunds within 10 working days of confirming that a refund is due; the time it then takes to appear in your account depends on your card issuer or bank.
8.9 Chargebacks. If you believe a refund is properly due, contact us first at support@seisly.com. Initiating a chargeback or payment dispute in respect of a fee that is non-refundable under this section, after work has begun, is a breach of these terms, and we reserve the right to recover the disputed amount together with our reasonable costs of recovery, including administrative and legal costs. Nothing in this clause affects any right you have under applicable law or your card scheme's rules to dispute a payment that was genuinely unauthorised or fraudulent.
8.10 Earlier orders. Orders placed before the date these terms take effect are governed by the refund terms that were in force when those orders were placed. This section applies to orders placed on or after that date and does not remove any refund right you had already acquired on an earlier order.
9.1 We do not guarantee, promise or represent that any application will be approved by HMRC.
9.2 Advance assurance is a discretionary service provided by HMRC. HMRC is not bound by its previous decisions and may refuse advance assurance even where a company appears to meet all qualifying conditions. HMRC's decision is final and there is no right of appeal against it.
9.3 Our AI review is designed to identify common issues and improve application quality. It does not constitute a legal opinion on whether your company qualifies for SEIS or EIS, and it may not identify every potential issue with an application.
9.4 HMRC typically takes 4 to 8 weeks to respond to advance assurance applications. We have no control over HMRC processing times.
9.5 You remain solely responsible for the accuracy and completeness of all information provided, and for ensuring the company continues to meet all qualifying conditions throughout the compliance period. Any loss of, or failure to obtain, tax relief or qualifying status that results from HMRC's decision or from matters outside our control is not something for which we are responsible.
10.1 Nothing in these terms limits or excludes our liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; or (c) any other liability that cannot lawfully be limited or excluded.
10.2 Subject to clause 10.1, we are not liable, whether the liability arises in contract, tort (including negligence), breach of statutory duty or otherwise, for any of the following, whether direct, indirect or consequential: (a) loss of profits, revenue, business or anticipated savings; (b) loss of, or failure to obtain, any tax relief, tax advantage or SEIS/EIS qualifying status, where that loss or failure results from HMRC's decision or from any matter outside our control; or (c) any indirect or consequential loss.
10.3 Subject to clauses 10.1 and 10.2, our total aggregate liability arising out of or in connection with each service we provide, whether in contract, tort (including negligence), breach of statutory duty or otherwise, is limited to the total fees you paid to us for that service.
10.4 The limitations and exclusions in this section reflect: the level of the fees; the fact that the outcome of an HMRC application is determined by HMRC and not by us; the availability to you of your own professional advisers and your own insurance; and the allocation of risk the parties consider reasonable in the circumstances. You should maintain your own arrangements for any loss that could exceed these limits.
11.1 Nothing in these terms excludes or limits our liability for fraudulent misrepresentation. Any other liability for misrepresentation is subject to, and limited by, section 10, to the extent permitted by section 3 of the Misrepresentation Act 1967.
12.1 The Seisly platform, including its design, software, and content, is owned by Litigo Limited. You may not copy, reproduce, or distribute any part of it without our written permission.
12.2 Documents we generate for your application belong to you once paid for and submitted.
13.1 These terms, and any dispute arising out of or in connection with them (including non-contractual disputes), are governed by the law of England and Wales. The courts of England and Wales have exclusive jurisdiction over any such dispute.
14.1 We may update these terms from time to time. We will notify you of material changes by email, and continued use of Seisly after changes take effect constitutes acceptance of the revised terms.
14.2 A change to these terms does not remove a right you had already acquired on an order placed before the change took effect. The terms that apply to a given order are those in force when that order was placed.
15.1 For refunds, cancellations or queries about these terms: support@seisly.com, quoting your order reference. For general enquiries: hello@seisly.com.
