The details that make it
usable every day.
Not a roadmap — this is what is in the product right now, on the free plan included.
Reusable templates
Save a document you send often and start the next envelope from it instead of from a blank upload.
Ordered recipients
Route to one signer or several, in sequence or all at once, with a different set of fields for each person.
Live document tracking
See who opened, viewed, and signed as it happens, with a complete event timeline per envelope.
On-demand reminders
Nudge whoever is holding things up without resending the document or restarting the workflow.
Decline with a reason
A recipient who cannot sign says why, and the reason is recorded on the envelope alongside everything else.
Custom branding
Put your logo, primary color, email subject, and invitation message on every signing request you send.
Where teams use it
Built for the documents that already move your work.
Nothing industry-specific to configure — the same workflow, pointed at the paperwork you send most.

No trial clock and no card. Ten envelopes every month, resetting on the 1st, with the whole workflow included — send, verify, sign, seal, and download the certificate.

HelixzSign captures electronic signatures in the browser, verifies each recipient with a one-time code sent to their email, and records a detailed audit trail alongside a signing certificate for every completed envelope. That evidence is what electronic signature law generally asks you to be able to produce. Organizations remain responsible for determining the legal and regulatory requirements that apply to their own use case.
Ten envelopes a month on the free plan, the full workflow included, and no card to enter. Your first sealed document and its certificate take about five minutes.
