Most buyers should pick eSign.com.
Choose eSign.com for a low-cost start: its Basic plan is free, and Premium is listed at $14.99 per user per month with annual billing. The web pricing page does not publish its monthly-billing price. Choose OneSpan Sign for enterprise agreement workflows, identity verification, or API and SDK access—but Enterprise pricing requires contacting sales. OneSpan lists transaction pricing, SMS from $0.40 per transaction, and identity verification from $2.50 per verification, so add-ons may affect the total.

02Pricing compared
eSign.com has the clearer low-cost starting point: its Basic plan is free and includes five sign requests, unlimited self-signing, 1GB of storage, and one user. Premium is listed at $14.99 per user per month with annual billing and includes unlimited sign requests and storage. The pricing page does not publish the monthly-billing price; app store listings show $29.99 per month.
OneSpan Sign does not publish a starting price or monthly or annual rates. Its Enterprise plan uses volume-based transaction pricing and requires contacting sales. The listed add-ons include SMS notifications from $0.40 per transaction and identity verification from $2.50 per verification, with a minimum commitment for identity verification. Some integrations may cost extra. For a small team, eSign.com is easier to budget; OneSpan’s total depends on sales pricing and usage.
03Features and depth
eSign.com covers common document tasks: preparing, editing, sending, signing, tracking, and storing documents. Its tools include a PDF editor for signatures, text boxes, and date fields; mobile scanning to turn photos into signable PDFs; reusable templates and custom links; and tamper-evident audit trails, two-factor authentication, and encryption in transit and storage. It also offers remote online notarization with certified notaries.
OneSpan Sign focuses on secure agreement workflows, with agreement preparation, signing, management, identity verification, and smart digital forms. Its Enterprise plan lists signing in 22 languages, a free sandbox with no time limit, and a REST API plus .NET, Java, Apex, iOS, and Android SDKs. The feature list points to more integration options for organizations building workflows, but identity verification is priced as an add-on. eSign.com’s published feature set is broader for PDF editing and notarization; OneSpan’s is more specific about APIs and enterprise workflows.
04Ease of use and learning curve
Neither source publishes enough detail to compare the actual learning curve, so we would not treat either as a proven easier product. eSign.com’s free Basic plan gives individuals a way to start with five sign requests, while Premium removes the request cap and adds unlimited storage. That makes the entry point and its limits relatively clear.
OneSpan Sign is presented around Enterprise workflows, and its pricing requires contacting sales. The listed sandbox, API, and SDK options may matter to teams integrating signing into existing systems, but they do not establish how simple setup or daily use will be. Ask OneSpan for a quote based on transaction volume and required add-ons before comparing total cost.
Questions people ask
Which is cheaper, eSign.com or OneSpan Sign?
eSign.com has the more transparent low-cost option: Basic is free, and Premium is listed at $14.99 per user per month with annual billing. OneSpan Sign does not publish Enterprise rates, so we cannot compare total costs without a quote and details about transaction volume and add-ons.
Does OneSpan Sign have a free plan?
The pricing information does not list a free OneSpan Sign plan or free trial. Its Enterprise plan includes a free sandbox with no time limit, but a sandbox is not the same as a production plan. Enterprise pricing is transaction-based and requires contacting sales.
Can I notarize documents with OneSpan Sign?
Remote online notarization with certified notaries is listed as an eSign.com feature. The published OneSpan Sign materials do not list notarization, so we cannot confirm that it offers the same capability. Check with OneSpan if notarization is a requirement for your workflow.
How is OneSpan Sign priced?
OneSpan Sign’s Enterprise plan uses volume-based transaction pricing, and the company requires contacting sales for pricing. The listed add-ons include SMS notifications from $0.40 per transaction and identity verification from $2.50 per verification, with a minimum commitment for identity verification. Some integrations may cost extra.
