About BoldSign

BoldSign is an electronic signature app and API made by Syncfusion, the North Carolina software company best known for its UI component libraries. It targets businesses that find DocuSign too expensive and want transparent pricing, a usable free plan and a developer-friendly API. Its core job is preparing documents, sending them for signature and tracking them to completion with a full audit trail.

The web app offers templates, signer authentication, automated reminders, in-person signing, team management and AI-powered field detection. Business adds unlimited envelopes, SSO, custom roles, scheduled send, a custom email sending domain and HIPAA support. Add-ons cover bulk send, bulk links, SMS and WhatsApp delivery, ID verification, knowledge-based authentication and qualified electronic signatures. The free Essential plan allows 25 envelopes a month, and a separate Enterprise API plan with a free sandbox handles embedded signing and webhooks.

BoldSign fits small and mid-sized teams that send a steady volume of contracts and want unlimited envelopes for a flat per-user price. It has fewer native integrations and less brand recognition than DocuSign, and several advanced options are paid add-ons. DocuSign is safer for complex enterprise routing, Dropbox Sign has a polished API with Dropbox ties, and signNow is a similar value option backed by airSlate.

A buying tip: yearly billing cuts Growth from $15 to $5 per user and Business from $25 to $15, and Business is the plan that removes envelope caps.
