Terms of service
These Terms govern engagements between Tannto and our clients. They sit alongside any signed Order or Statement of Work and define the standing rules of the relationship. By signing an Order, accepting a written proposal, or instructing us to begin work, you agree to these Terms.
Last updated: 10 May 2026
In these Terms:
A contract forms when you sign an Order, return written acceptance of a proposal, or otherwise instruct us to begin work and we begin. Each Order, together with these Terms, is a separate contract.
Where there is a conflict between documents, the order of precedence is: (a) the signed Order or Statement of Work; (b) these Terms; (c) any proposal, deck, or written communication. The Order wins on commercial terms. These Terms govern the legal framework.
3.1 Pipeline. We design and run cold outbound campaigns on your behalf (email, LinkedIn, or both), including infrastructure, lead sourcing, copy, deliverability management, reply handling, and reporting. The scope of any specific Pipeline engagement is set out in the Order.
3.2 Sales OS.We design and build a bespoke sales platform around your existing stack. The platform's capabilities are defined in the Order. Unless agreed otherwise in writing, your team operates the platform day to day, and we maintain it under the agreed retainer.
3.3 Discovery. The discovery call before any engagement is free. If we do not believe we can move the numbers for you, we will say so on the call.
3.4 Outcomes. Any meeting volumes, response rates, timelines, or other figures we discuss before or during an engagement are reasonable estimates based on similar work, not commitments. Outcomes vary by market, ICP, offer, and conditions outside our control. We do not guarantee specific commercial results.
4.1 Inputs. You will provide the access, information, and approvals reasonably required for us to deliver the Services. This typically includes ICP briefing, access to your CRM and (where relevant) your calendar and inbox infrastructure, brand context, and timely sign-off on materials sent for approval.
4.2 Accuracy. You warrant that the information and target lists you supply to us are accurate to the best of your knowledge and lawfully held.
4.3 Delays. If we are delayed by your inputs, approvals, or third-party access, we may extend timelines accordingly. Fees continue to accrue during such delays.
4.4 Authority. You confirm that the person signing the Order has authority to bind you and to grant us the rights and access set out in these Terms.
5.1 Fees. The Fees, billing cadence, and any out-of-pocket expenses are set out in the Order.
5.2 Invoicing. Unless the Order states otherwise, invoices are payable within 14 days of issue, in pounds sterling, to the account specified on the invoice.
5.3 Late payment.If an invoice is not paid by its due date, interest accrues at the statutory rate set under the Late Payment of Commercial Debts (Interest) Act 1998 (8% above the Bank of England base rate), together with the statutory compensation provided for under that Act. We may also suspend the Services on five Business Days' written notice while payment remains outstanding.
5.4 Taxes. All Fees are exclusive of VAT, which is added at the prevailing rate where chargeable.
5.5 Third-party costs. Subscriptions to tools that run on your own accounts, including CRM, email infrastructure, data providers, AI APIs, and LinkedIn Sales Navigator, are paid by you directly to the relevant provider. We will tell you what is needed before the engagement begins.
Either party can request a change to scope, deliverables, or timing in writing. We will respond with the impact on price and timeline. The change becomes effective only once both sides confirm in writing. Work outside the agreed scope is not chargeable until the change is agreed.
7.1 Pre-existing IP. Each side keeps ownership of the IP it brings to the engagement. This includes our methodology, frameworks, prompts, code libraries, and reusable components, and your brand, content, data, and existing systems.
7.2 Pipeline. On full payment of the Fees due, you own the campaign-specific copy and assets developed for you under a Pipeline engagement. We retain ownership of the underlying methodology, sending infrastructure, internal tooling, and any general patterns that are not unique to you.
7.3 Sales OS. Ownership of intellectual property in the Sales OS Deliverables, and any licences granted between us, are as set out in the applicable Order.
7.4 Your data. You retain all rights in the data you provide and in the data generated by your use of the Services. We do not claim ownership of your data and will not use it for any purpose outside the engagement.
7.5 Aggregated learnings. We may use anonymised, aggregated insights derived from our work to improve the Services for our clients generally. Nothing identifying you or your data is shared.
7.6 Case studies. We will not name you publicly, use your logo, or publish a case study about our work together without your written approval.
8.1Each side will keep the other's confidential information confidential, use it only for the purposes of the engagement, and protect it with the same care it applies to its own confidential information (and at least a reasonable standard).
8.2 Confidential information does not include information that is already public, was already known, is independently developed, or is required to be disclosed by law or regulator. Where disclosure is required, the disclosing party will give notice where it lawfully can.
8.3 These obligations continue for three years after the engagement ends.
9.1 Each party will comply with applicable data protection law, including the UK GDPR and the Data Protection Act 2018.
9.2 Where we process personal data on your behalf in delivering the Services, we do so as your processor. The terms required under Article 28 UK GDPR, including the subject matter, duration, nature and purpose of processing, the types of data and categories of data subjects, and our security and sub-processor obligations, are set out in our standard Data Processing Addendum, which forms part of the contract on request.
9.3 Where we source or enrich prospect data using our own tools and methods, we may act as a controller for that processing. We carry out and maintain a documented Legitimate Interests Assessment for B2B prospect outreach and will provide a copy on reasonable request.
9.4 We will notify you without undue delay, and in any event within 72 hours of becoming aware, of any personal data breach affecting your data.
10.1 PECR.Cold outreach to corporate subscribers is permitted under regulation 22 of the Privacy and Electronic Communications Regulations where the message is identifiable, relevant to the recipient's business role, and provides a clear opt-out. We deliver Pipeline accordingly.
10.2 Sole traders. For sole traders, partnerships, and unincorporated businesses, we apply the same standards as for individuals. You will tell us before the engagement begins if your target market includes such recipients, so we can scope accordingly.
10.3 Suppression. We maintain bounce, complaint, and opt-out suppression lists for every Pipeline engagement and honour all unsubscribe requests promptly. You will share any contact-level suppressions you hold so we can apply them on day one.
10.4 Domain separation. Pipeline runs on dedicated sending infrastructure that is not your main domain. Your primary brand and transactional email remain untouched.
10.5 Your data. You warrant that any contact data you supply was lawfully obtained and that you have a valid lawful basis to share it with us. If a regulator queries data you supplied, we will cooperate. If action is taken in respect of that data, you will indemnify us against direct fines or losses arising solely from that data.
11.1 We will provide the Services with reasonable skill and care, in line with the standards of a competent UK professional in the same field.
11.2 We will use commercially reasonable efforts to meet the timelines and milestones in the Order. Dates are estimates unless explicitly stated as fixed.
11.3 Save as expressly set out in these Terms or the Order, all other warranties, conditions, and representations, whether express or implied, statutory or otherwise, are excluded to the fullest extent permitted by law.
11.4 In particular, we do not warrant any specific outcome, conversion rate, meeting volume, or revenue figure. Sales is a function of many variables outside our control. The estimates in our proposals are based on similar work; they are not guarantees.
12.1Nothing in these Terms limits or excludes either party's liability for: (a) death or personal injury caused by negligence; (b) fraud or fraudulent misrepresentation; or (c) any other liability that cannot be limited or excluded under English law.
12.2 Subject to clause 12.1, neither party is liable to the other (whether in contract, tort, breach of statutory duty, or otherwise) for: (a) loss of profits; (b) loss of revenue; (c) loss of goodwill or reputation; (d) loss of anticipated savings; (e) loss of business opportunity; (f) loss or corruption of data; or (g) any indirect, special, or consequential loss.
12.3 Subject to clause 12.1, our total aggregate liability arising out of or in connection with the engagement (whether in contract, tort, breach of statutory duty, or otherwise) is limited to the greater of: (a) the Fees actually paid by you to us under the relevant Order in the 12 months immediately before the event giving rise to the claim; or (b) £50,000.
12.4 Each party will use reasonable endeavours to mitigate its losses.
13.1 Initial term. Unless the Order states otherwise, the engagement runs for an initial term of three months from the start date.
13.2 Renewal.After the initial term, the engagement continues on a rolling basis until either party gives 30 days' written notice of termination. One-off Sales OS build engagements end on completion and acceptance of the agreed Deliverables.
13.3 Termination for cause. Either party may terminate the engagement immediately on written notice if the other: (a) commits a material breach that is not remedied within 14 days of written notice; (b) becomes insolvent or enters any analogous procedure; or (c) ceases to carry on business.
13.4 On termination. You will pay all Fees due up to and including the date of termination, plus any committed costs we cannot recover. We will return or, at your option, securely delete your confidential information and personal data, save where we are required to retain it by law. Clauses that by their nature should survive termination, including 7 (intellectual property), 8 (confidentiality), 9 (data protection), 11.3 to 11.4, 12 (liability), and 14 (general), will do so.
14.1 Force majeure. Neither party is liable for any failure or delay caused by events beyond its reasonable control, including acts of God, war, civil unrest, government action, network failure, or third-party service outages. The affected party will notify the other promptly and use reasonable endeavours to resume performance. If the event continues for more than 60 days, either party may terminate on written notice.
14.2 Assignment.Neither party may assign or transfer its rights and obligations without the other's written consent, save that we may assign to a successor in connection with a merger, restructure, or sale of our business.
14.3 Notices. Notices under these Terms must be in writing and sent to the email addresses on the Order or to such other address as the recipient notifies in writing.
14.4 No partnership. Nothing in these Terms creates a partnership, joint venture, or agency relationship between us.
14.5 Third parties. A person who is not a party to these Terms has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any of them.
14.6 Entire agreement. These Terms and the Order set out the entire agreement between the parties on the subject matter and supersede any prior discussions or proposals. Each party acknowledges it has not relied on any statement not set out in these documents. Nothing in this clause limits liability for fraud or fraudulent misrepresentation.
14.7 Variations. These Terms may be varied only by written agreement signed by both parties. We may update these Terms from time to time for new engagements; the version in force when an Order is signed governs that engagement.
14.8 Severability. If any provision is held to be invalid or unenforceable, the remainder of these Terms continues in full force.
14.9 Waiver. No failure or delay in exercising a right is a waiver of that right.
14.10 Governing law and jurisdiction. These Terms and any dispute arising out of or in connection with them are governed by the laws of England and Wales. The parties submit to the exclusive jurisdiction of the English courts.
