Description
Getting a contract signed, verifying who actually signed it, and then collecting payment for it usually means stitching together three separate tools — an e-signature service, an ID-verification provider, and a payment processor. Chaindoc combines all three into one workflow: you send a document, the signer's identity is checked, they sign, and payment can be collected in the same flow, with every step recorded in a way that's cryptographically provable later.
On the technical side, Chaindoc offers eIDAS/ESIGN Act/UETA-compliant e-signatures, KYC with liveness checks and sanctions screening, Stripe Connect for payment processing, and a SHA-256 blockchain audit trail for document integrity. It's ISO 27001 and ISO 9001 certified, offers a REST API and webhooks, and claims 99.9% uptime with 10,000+ signed documents processed. Pricing runs from a free tier (5 signatures/month) to €29/month for teams needing higher volume.
💬 Our review
The short version: if you regularly need signed agreements where you also have to verify who's signing and collect payment — think freelance contracts, real estate paperwork, or client onboarding in regulated industries — Chaindoc bundles signature, identity check and payment into one flow instead of three separate subscriptions.
Against DocuSign, which is the default choice for e-signature alone and has a far bigger integration ecosystem, Chaindoc's pitch is the bundle: you'd otherwise pay for DocuSign plus a KYC provider plus Stripe integration work separately. The blockchain audit trail is a differentiator for non-repudiation claims, though for most small teams the practical benefit over a standard signed-PDF audit log is marginal unless you're in a sector where that provability actually gets tested (insurance, high-value real estate, legal). At €9/month for individuals, it's priced accessibly to try; the free tier's 5 signatures/month is enough to test the workflow before committing.
