Contractbook vs Docusign eSignature REST API

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.
