Questions teams ask before switching to Chaindoc
Moving from DocuSign, PandaDoc, or another e-signature tool? Here are clear answers to the common questions.
Chaindoc is an agreement management and contract template software platform. You sign contracts, verify identity with built-in KYC, and collect payments without bouncing between three separate tools.
It fits freelancers, SMBs, and growing companies handling real agreements across real estate, healthcare, insurance, fintech, and IT services. Draft, sign, verify, and track contract management from one workspace.
Chaindoc bundles e-signature, KYC identity checks, and Stripe contract payments in one workflow. DocuSign, PandaDoc, and Adobe Sign require separate tools or add-ons for identity verification and payment collection.
Side-by-side comparisons: DocuSign, PandaDoc, Adobe Sign, HelloSign, SignNow, and Yousign.
Zero migration fee. Import your existing contract templates as PDFs, configure signing flows in the dashboard, and set up team roles. Most teams switch in under an hour.
Start on the Free tier (€0 for up to 5 signatures/month and 100 MB storage) or see pricing for paid plans from €9/month to €29/month.
Upload a PDF or pick a template in our electronic signing flow, drop in signature fields, add signers, and send. Recipients sign in the browser on desktop or mobile, and every step logs who signed, when, and with what verified identity.
The signed PDF returns to your dashboard with a SHA-256 hash anchored on blockchain so anyone, including courts, can verify signature integrity.
Yes. KYC identity verification via Sumsub is built directly into the signing flow: the signer verifies their government ID and liveness check, and only then signs.
You can require identity verification per signing request for financial agreements, real estate deals, or onboarding. The verification record stays attached to your off-chain audit trail.
