About BoldSign

BoldSign is an e-signature service from Syncfusion, the company known for developer UI components. It handles the usual signing jobs: upload documents, place fields or let it detect them, send to signers in order, use templates, collect attachments, send reminders and keep an audit trail. Security options include two-factor authentication, signer verification and passwordless sign-in. Its pricing is one of the lowest among established services: a free Essentials plan includes a set number of envelopes and templates each month for a single user, and paid plans start at a few dollars per user per month with more envelopes, shared templates, branding and team features. A separate API plan prices by envelope for developers embedding signing in their apps, and AI tools help prepare documents. There are mobile apps for iOS and Android. It is less known to signers than Docusign and has fewer native integrations, but for small businesses watching costs it is a strong pick.

Best for: Small businesses and developers who want reliable signing at a very low price.
