What BoldSign does
BoldSign is an electronic signature product that lets teams send documents for signing, follow their status and keep a record of each step. It is offered as a web app, with iOS and Android mobile apps, and as an API for developers who want to build signing into their own software. The vendor says it is part of Syncfusion.
Capabilities named on the official pages include AI field detection, AI search, bulk send from a CSV file, signing links that can be embedded in an app or sent by email, SMS or WhatsApp, signer verification and branding of requests with your own logo and colors. Every plan lists an audit trail with the full document history. Integrations listed include Salesforce, HubSpot, OneDrive, Power Automate, Zapier and Xero, and the vendor states compliance with SOC 2, GDPR, HIPAA and PCI DSS.
Pricing is freemium and shown in USD. The Essential plan costs $0 and covers 25 envelopes a month and 2 templates. Growth is $5 per user per month billed yearly or $15 per user per month billed monthly, with 50 envelopes per user monthly and 10 templates. Business is $15 per user per month billed yearly or $25 per user per month billed monthly, with unlimited envelopes and templates. Premium is $99 per month billed yearly or $138 per month billed monthly, with unlimited users and 250 envelopes a month. The Enterprise API plan starts from $30 per month and includes 40 envelopes, then $0.75 per envelope; the page shows only one price for it and does not say whether it is billed monthly or yearly. A 30-day free trial is available.

Cons
- Essential is capped at 25 envelopes per month and 2 templates

- Enterprise API shows a single starting price without a stated billing period
Our take
BoldSign looks like a fit for small teams and developers who want a free starting point and clearly separated plan tiers. Individuals sending a few documents can stay on the free Essential plan, while teams that send many documents can move to Business, where envelopes are unlimited. Premium suits many senders sharing one flat price. The trade-offs are plan gating: bulk send, ID verification, SMS and WhatsApp delivery are listed as add-ons, several integrations need Business or higher, and live API use needs the separate Enterprise API plan. The official pages say nothing about Linux, macOS, Windows or Slack apps, so check that before committing.
