by Syncfusion, Inc.Electronic signatures
Syncfusion’s e-signature app and API, with a 25-envelope free plan, per-user plans from $5 a month billed yearly and per-use prices for QES, ID checks and SMS.
Unlimited sending with SSO, HIPAA and a storage region choice at $15 per user a month billed yearly, with QES, ID checks, SMS and bulk send priced per use.
BoldSign’s Business plan puts features that are often sold by quote on a self-serve price: unlimited envelopes and templates, single sign-on, SCIM provisioning, HIPAA support and IP restrictions, at $15 per user a month billed yearly. Identity checks, SMS delivery, bulk send and qualified (QES) signatures are add-ons with published per-use prices, so the bill can be worked out from the pages. Every plan, the free one included, keeps an audit trail, seals documents with an AATL certificate and stores data in the US, EU, Canada or Australia. A live API starts at $30 a month.

| Bottom line | From its public pages, BoldSign has the lowest price of the five for our 3-sender scenario and puts SSO, HIPAA, four storage regions and per-use QES on a self-serve plan. Check how Growth counts envelopes; no ISO 27001 certificate is named. | From its public pages, DocuSeal pairs a low per-seat price for unlimited web sending with an API billed per completed document, its own SOC 2 and ISO 27001, and an open-source edition. Usage fees and support-enabled add-ons need planning. | From its public pages, Dropbox Sign is a per-sender service with unlimited signature requests, evidence on every document and compliance reports in its own name. SSO, data residency, HIPAA and QES go through sales, and the API is priced by monthly quota. | From its public pages, DocuSign eSignature has the longest certification list of the five and evidence features on every plan. It is priced per seat with an envelope allowance, so steady volume costs more than with the flat-rate rivals, and SSO and HIPAA sit on higher or sales-led plans. |

Review from public pages
Written from BoldSign's public pages (pricing, security or privacy, and docs) as read on Oct 15, 2026. We did not sign up, and no hands-on run is published yet.
We read BoldSign's pricing page (web app and API tabs, the plan table and FAQ), the pricing calculator and the script it loads, the help-center articles on pay-as-you-go prices, plan limits and API billing, the QES, security, SOC 2, HIPAA, GDPR, data residency and subprocessor pages, the Terms of Use and support SLA, and the developer docs (getting started, sandbox, rate limits, versioning, webhooks, SDKs, changelog) on Oct 15, 2026; we did not sign up, request a quote or call the API for this review. Every price on the pages is in US dollars.
The pages make the plans clear. The pricing page has a Yearly and a Monthly tab: $5, $15 and $99 (Growth, Business, Premium) on the yearly tab and $15, $25 and $138 on the monthly one, which the page markup and the calculator's own figures confirm. Business has unlimited envelopes, a help article prices each pay-as-you-go add-on per use (the Xero and Salesforce integration add-ons are monthly fees on the pricing page), and the docs publish the API rate limits (2,000 requests per hour per account live, 50 in the sandbox).
A few things need a question. Growth's 50 envelopes a month are per user on the plan card and in the calculator, but the plan table's note defines its 50 as the total for the account, and a help article lists 50 a month without saying per user. An extra Enterprise API user costs $28 in the plan table and $15 in the calculator. The plan card says HIPAA is turned on by signing the BAA in the app settings, while the plan table and the HIPAA overview say to request the BAA through a form. And the free plan's 25 envelopes become 5 for sign-ups with a personal email address such as Gmail.
Three Growth seats cost $15 a month billed yearly, assuming the 50-envelope allowance is per user, as on the plan card. Business, with unlimited envelopes, would be $45.
vs Dropbox Sign: SignWell Business is $30 a month for 3 senders, DocuSeal Pro $50 and Dropbox Sign Standard $75, all billed yearly.
Business ($15 per user a month billed yearly) lists SSO, SCIM provisioning, custom roles, IP restrictions and HIPAA, and can be bought online.
vs Dropbox Sign: Dropbox Sign offers SSO on Premium, priced by quote; DocuSign sells the HIPAA BAA through sales.
Qualified signatures through the trust service provider Evrotrust cost $3 each, ID verification $2 and KBA $1.50 per use, on Business and up.
vs Dropbox Sign: DocuSign and Dropbox Sign offer QES through sales; SignWell states eIDAS at the simple-signature level only.
Essential sends 25 envelopes a month with an audit trail, tamper-proof documents and a choice of storage region, for sign-ups with a business email address.
vs Dropbox Sign: DocuSeal’s free plan sends 10 signature request emails a month; Dropbox Sign’s and SignWell’s send 3.
The data residency page lists the US, the EU (Netherlands), Canada and Australia, and the plan table lists the choice on every plan, the free one included.
vs Dropbox Sign: Dropbox Sign lists six regions on Premium (quote); SignWell offers no choice of storage region.
The plan card and the calculator give 50 envelopes a month per user; the plan table gives 50 for the whole account, and a help article lists 50 a month without saying per user. Growth has no pay-as-you-go option for more.
Workaround: Ask support before buying, or choose Business, which has unlimited envelopes ($45 a month for 3 users billed yearly).
The security, SOC 2 and HIPAA pages and Syncfusion’s Security Management Report name SOC 2 Type 2 but no ISO 27001 certificate. The SOC 2 report is available on request.
Workaround: Request the SOC 2 Type 2 report through the form on the SOC 2 overview page.
The data residency page says the region cannot be changed later; switching means a new account. Billing and ID-verification data stay in the US whatever the region.
Workaround: Choose the region when you create the account, before sending the first document.
The web-app plans include only the sandbox. Live sending needs the Enterprise API plan ($30 a month for 40 envelopes, then $0.75 each) with two application users; an extra one is $28 or $15 depending on the page.
Workaround: Build and test in the free sandbox first; its documents are watermarked and deleted after 14 days.
Billing is per user on Growth and Business, a flat price for unlimited users on Premium, and per envelope on the API and add-ons. Billed yearly, Growth is $5 per user a month (50 envelopes per user on the plan card), Business $15 (unlimited) and Premium $99 for 250 envelopes, then $0.50 each; monthly billing is $15, $25 and $138. The free plan gives 25 envelopes a month, or 5 for sign-ups with a personal email domain. For 3 senders at 30 envelopes a month, Growth comes to $15 a month and Business to $45 (our arithmetic). Premium costs less than Business from 7 users if the account stays within 250 envelopes. Add-ons start at Business and are billed per use. The Terms say fees are non-refundable and exclude taxes, and plans renew automatically.
Signed documents and audit trails can be downloaded from the app, with an option to merge the audit trail into the PDF, and Business and up back up documents to Google Drive, OneDrive or Dropbox automatically. Templates export to JSON, and the API has download endpoints. The Terms say access ends at termination, so download first; accounts inactive for more than six months may be scheduled for deletion.
From its public pages, BoldSign has the lowest price of the five for our 3-sender scenario and puts SSO, HIPAA, four storage regions and per-use QES on a self-serve plan. Check how Growth counts envelopes; no ISO 27001 certificate is named.
