E-Sign vs. Assembly

At eSign.co.uk, we make signing smarter. We provide a secure, eIDAS compliant, and easy-to-use electronic signature platform that helps businesses digitise document workflows, reduce paperwork, and improve productivity. Unlike other providers, eSign.co.uk provides advanced electronic signatures as default, meaning you can sign with confidence that your signature is legally binding. Simple e-signatures without proper verification can be challenged in court. eSign ensures every signature is secure and legally compliant, so your documents hold up when it matters most.

Assembly is the AI-powered platform for professional service firms, from accounting and bookkeeping practices to agencies and consultants. It combines a branded client portal, a simple CRM, and an AI app builder that lets your firm add any software it needs without a dev team. Clients get one branded place for messages, files, forms, tasks, contracts and e-signatures, and invoices they can pay online. Your team runs on a CRM with automated reminders and an AI Assistant that knows full client context. When your firm needs something the portal doesn’t do yet, describe it.
