Most buyers should pick BoldSign.
Choose BoldSign if you want a free tier or a published entry price: its Essential plan includes 25 envelopes monthly, while Growth lists $5/user/month with annual billing ($15 month-to-month). Choose OneSpan Sign if your priority is enterprise agreement workflows, API and SDK access, and transaction pricing that scales by volume—but its pricing page gives no base price. Compare BoldSign’s verification, SMS, and extra-user fees before committing.

02Pricing compared
BoldSign is easier to budget from its published prices. Its free Essential plan includes 25 envelopes a month and one user; personal-email signups are limited to five envelopes monthly until verified. Growth lists $5 per user/month with annual billing, or $15 month-to-month, for 50 envelopes per user. Business is $15 per user/month annually or $25 month-to-month, with unlimited envelopes. OneSpan Sign publishes no base price: its Enterprise plan uses transaction-based pricing, and buyers must contact sales. Its page says a transaction can include any number of recipients and documents. Check BoldSign’s extras before comparing totals: ID verification starts at $2 each, SMS at $0.20, and additional users cost extra on Growth and Business. OneSpan lists SMS notifications from $0.40 per transaction and identity verification from $2.50, with a minimum commitment. These fees make headline prices an incomplete comparison.
03Features and depth
BoldSign’s published features cover everyday signing workflows and some specific ways to handle volume. It supports mobile signing, embedded signing, custom branding, and bulk requests to hundreds of recipients using a CSV. It also lists AI field detection, AI Search and MCP integration. Identity checks can use ID documents and biometrics, though verification may add fees. OneSpan focuses its product description on secure agreement workflows: preparation, signing and management, with identity verification, smart forms and fraud prevention. Its Enterprise plan includes a REST API and SDKs for .NET, Java, Apex, iOS and Android. The pricing page also lists signing in 22 languages and a free sandbox with no time limit. Those details make OneSpan worth evaluating for organizations building agreement workflows or handling volume, but the source does not publish feature-by-feature limits or a base price. BoldSign gives buyers more visible plan caps; OneSpan gives more detail on transaction-based enterprise access.
04Ease of use and learning curve
The available information does not establish which product is easier to use, and neither description includes setup steps or learning resources. Our review scores rate BoldSign’s ease of use at 7.5 and OneSpan’s at 6, but no scoring method is provided, so treat that as directional rather than proof. BoldSign’s plans make the user and envelope limits visible, but its free plan restricts personal-email signups to five envelopes a month until verified. OneSpan’s published offer is Enterprise-only and requires contacting sales for pricing; its free sandbox may help teams assess API workflows, but it is not a published self-serve plan. If you need a quick, predictable starting point, BoldSign has the clearer entry plan. For OneSpan, confirm implementation requirements and transaction costs with sales before switching.
