#1 of 9 e-signature services
Facts checked 8 Oct 2026

In short

The free Essential plan allows 25 envelopes a month and 2 templates, with an audit trail on every document¹.
Growth, the cheapest paid plan, costs $5 a user a month on yearly billing ($15 on monthly billing) and allows 50 envelopes a user a month¹.
Business costs $15 a user a month on yearly billing, with unlimited envelopes and single sign-on; bulk send is listed as an add-on¹.
Qualified electronic signatures (QES) are listed for Business and above, and SOC 2 Type II is listed on every plan^1,4.
Live API access starts with the Enterprise API plan at $30 a month, which includes 40 envelopes¹.

BoldSign suits small teams that want a low entry price and a path to qualified EU signatures, ID checks and single sign-on without a custom quote^1,2. The free plan and the $5 Growth plan cover light use, with 25 and 50 envelopes a month¹. The catch: bulk send, ID checks and QES sit on Business or above, and the API is a separate plan¹.

Best for: Small teams that want cheap plans and a qualified-signature option.
