Contractbook vs Signater

Contractbook is a cloud-based platform for teams to create, collaborate on, sign, centralize, track, and connect contracts. Users can prepare drafts with information from CRM systems, forms, or other tools, then work from pre-approved templates. Collaboration includes approval workflows, suggestions, comments, and version history. Electronic signatures support signing order, identity verification, and two-factor signing; recipients can complete signing without a Contractbook account. Existing contracts can be bulk imported, scanned, organized, searched, and managed with permissions, with data extraction available. Contract information can generate deadline and renewal reminders and customizable tasks after signing. Contractbook advertises more than 3,000 integrations, including Salesforce, HubSpot, Pipedrive, Google Calendar, Slack, Zapier, and Make.com. It states that it is SOC 2 and GDPR compliant and describes security measures including encryption and regular black-box penetration testing. A free plan and 14-day trial are available. Centralize is listed at $399 a month and Growth at $599 a month, both billed annually.

Signater is a digital contract service that lets businesses send, sign and track agreements through a browser. An envelope can gather several documents and signers into a sequential or parallel process, ending with a completion certificate. Signers can be checked using passwords, email or SMS codes, selfies with liveness checks, identity documents, facial biometrics or geolocation. Reusable templates hold standard text, with fields for variable details and a new version for each edit. The REST API can create and track envelopes, send them, upload documents, use templates, and retrieve signed files and certificates; API and webhook access is limited to Business and Enterprise plans. Webhooks send envelope events by POST and retry automatically. Signater lists HTTPS/TLS, HSTS and AES-256 encryption among its security measures, and signed PDFs can include embedded PAdES signatures, hashes and timestamps. Signers open links on phones or computers without an account or app. The platform and signing flow support six languages. A free plan includes three envelopes monthly; paid plans start at $39/mo.
