BoldSign vs Proposify

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.

Proposify is a proposal management platform from Halifax, Nova Scotia, Canada. It was co-founded by Kyle Racki and Kevin Springer, who ran a web design agency and sold it in 2013 to focus on the product after years of building proposals by hand. Its core job is helping sales teams create, send, track and get signatures on proposals, quotes and contracts.

The editor works from templates and a shared content library, with interactive pricing tables, optional line items, a product catalog, custom fields and variables, and built-in e-signatures. Document insights show when a buyer opened a proposal and which sections they read. Plans are per user: Build covers documents, signatures, AI writing and the MCP server; Grow, billed annually, adds roles, approval workflows, account metrics and API access; Scale is an annual platform fee for ten users with SSO, multiple workspaces and premium Salesforce or Aspire integrations.

Proposify fits agencies, B2B service firms and sales teams that send designed proposals and want control over what goes out. PandaDoc is broader, with a free e-signature plan and stronger document automation, while DocuSign is about signatures, not proposal design. Oneflow is the stronger pick for contract lifecycle work in Europe.

Watch the send limits: every plan includes a monthly quota of sent documents, and extra sends are billed per document. Proposify now offers an MCP server so AI assistants such as Claude can create and update documents, and its 14-day trial needs no credit card.
