Best Sertifi Alternative for Startups in the UK (2026)

Sertifi is an agreements and payments platform best known in hospitality, travel and events. It lets a business send an agreement, collect an e signature, and authorise a payment in one flow, which is a neat fit for bookings, group contracts and deposits. It is strong at that specific job. The reason a UK startup looks at an alternative depends on the startup. If you are not in hospitality or events, you probably want a broader contract tool that drafts, reviews and tracks agreements of every kind, with real AI, rather than a signing and payment flow built for a particular industry. ## What Sertifi is, and the team it suits Sertifi combines electronic signatures with secure payment authorisation, so a customer can agree and pay in the same step. It is widely used by hotels, travel companies and event organisers to handle booking agreements, credit card authorisations and group contracts. It suits a business whose contracts are tied to taking payment at the point of agreement. For that use case Sertifi is purpose built and does it well, and its industry focus is a genuine strength. ## Why a startup looks for an alternative A startup buys software on predictable price, speed to value and self serve setup. If your business is not hospitality or events, the payment linked signing that makes Sertifi special is not your main need. A typical startup wants to draft a first version of an agreement, review incoming customer and supplier contracts, flag risky clauses before signing, sign, and track renewals, across all contract types. That calls for a broader contract workspace with AI, not an industry specific agree and pay tool. ## Where Sertifi still leads Sertifi still leads on combining e signature with payment authorisation for hospitality, travel and events. If your contracts are bookings or group agreements where you need to collect a signature and a payment together, that is Sertifi's home ground and a general contract tool will not match it. For a startup in those industries it deserves a place on the shortlist for exactly that reason. ## The alternatives worth a UK startup's time in 2026 Each tool below is a real product with genuine strengths. Treat them as starting points for your own shortlist, not a ranking, because the right pick depends on your contract mix, your budget and how much you want AI to do. - Juro is a London based all in one contract platform with a clean browser editor, templates and e sign, strong for a lean UK team.

• Oneflow is a Swedish contract automation and e sign tool with transparent tiers and quick self serve setup.
• Concord covers signing, storage and light approvals at a published price for an administrative heavy startup.
• Adira is an AI native workspace for drafting, clause level review, editing, repository and tracking in one place, with transparent per seat pricing. ## How to compare them on your own contracts The most reliable way to choose is a small, repeatable test, not a feature checklist. Adira has not published an independently adjudicated head to head against Sertifi, and most vendors in this category have not either, so test both yourself. Take ten to twenty of your own real agreements, for example your NDAs, a services agreement and a few supplier or customer contracts, load the same set into each tool during the free trial, and score them on the same metrics: critical clause and risk detection rate, missed renewal or notice date rate, time to a usable first draft, and three year total cost. A test you can repeat on your own contracts beats any vendor claim. ## Where Adira fits for a startup Adira is an AI native legal workspace that brings drafting, understanding, editing, tracking and governance of every contract into one place, rather than an agree and pay flow for one industry. For a startup outside hospitality and events, a single workspace that handles all your contract types is the point, because nobody is spare to manage several narrow tools. Adira is built on Anthropic's Claude, models each contract as a structured clause tree rather than flat text, and tunes a company persona from your own documents so drafts come out in your style. It flags each clause as favourable, neutral or unfavourable, and it does not train on your contract corpus. It includes e sign and e stamp. Data is encrypted in transit and at rest with role based access, which supports your obligations under the UK GDPR and the Data Protection Act 2018, and the Enterprise tier adds SSO and SAML, audit logs and data residency. Unlike Sertifi, which is generally quoted for a business, Adira publishes its pricing. The Practice plan is $89 per seat each month billed annually (approximately £70), or $109 billed monthly, with a minimum of three seats. The Firm plan is $179 per seat each month billed annually (approximately £141), or $219 billed monthly, with a minimum of five seats. These are approximate conversions, so check Adira's pricing page for current figures. There is a custom Enterprise tier and a seven day free trial. One honest caveat is that Adira does not combine signature with payment collection the way Sertifi does, so if you need agree and pay together, Sertifi remains the better fit. And the three seat minimum means your entry cost reflects a small team even if only one person starts. Adira reports its own measured result: eighteen law firms use it, and contract review and due diligence work that used to take ten to twelve days now takes under two hours. Treat that as Adira's own attributed figure with the method stated, not an independent benchmark. Adira's legal depth is India first and expanding, so a UK startup should run it on its own UK agreements during the trial and confirm coverage before committing. See Adira for details. ## How to choose If you are in hospitality, travel or events and need signing and payment together, Sertifi is a fair, purpose built pick. If you want a broad AI contract workspace across all your agreement types, compare Juro and Adira, look at Oneflow for automation and e sign, and consider Concord if your needs are mostly signing and storage. Shortlist two or three, run the same set of your own contracts through each during the free trials, and score them on detection accuracy, missed dates, draft speed and three year cost. The tool you use every day beats the one that wins a demo. This article is general information, not legal advice.
