Bottom line
BoldSign is Syncfusion's e-signature platform, priced around unlimited envelopes at $15 per user per month (annual billing) or a flat $99/month Premium plan with unlimited users.

The vendor cites 50,000+ customers in 120+ countries and a 30-day free trial.
Frequently asked questions
How much does BoldSign cost?
Business is $15 per user per month on annual billing ($25 monthly) with unlimited envelopes and unlimited templates. Premium is a flat $99 per month on annual billing ($138 monthly) with unlimited users and 250 envelopes per month, after which extra envelopes cost $0.50 each. Annual billing is advertised as saving 40% versus monthly. A 30-day free trial requires no credit card.
How quickly can a team get to first value?
BoldSign says a first contract can be sent within minutes of signing up, and it publishes copy-and-paste API samples in cURL, C#, Java, PHP, Python and Node so a developer can send from a template programmatically on day one. There is no stated implementation fee.
Does BoldSign offer AI features or an MCP server?
Yes. The homepage markets 'AI-Powered eSignatures' with AI field detection and AI search, and it lists an MCP integration among its features, so a Model Context Protocol path is vendor-stated. The homepage does not say whether models are vendor-hosted or customer-supplied, and no AI activity logging or audit export is described, so those remain unverified.
What integrations does BoldSign support?
BoldSign lists native integrations for Salesforce, HubSpot, Microsoft OneDrive, Power Automate, Zapier and Xero, and offers a REST API with SDKs plus embeddable signing links delivered by email, SMS or WhatsApp.
Is BoldSign secure and compliant?
The vendor's homepage states that BoldSign meets SOC 2, GDPR, HIPAA and PCI DSS and that signatures are enforceable under the ESIGN Act and eIDAS, using AES-256 encryption. This review only had the homepage, not a dedicated trust or compliance page, so treat those certifications as vendor claims to confirm in procurement.
What support is available?
BoldSign states its support team will help customers even on the free plan, and it advertises excellent customer support as a differentiator. The homepage does not name a specific support channel, portal or response-time SLA, so support terms should be confirmed with the vendor.
