E-signature, built for how teams actually send

Send it. Get it signed. Move on.

Upfinity Sign gets documents from draft to signed with an audit trail that holds up — without the per-seat markup of legacy e-signature tools.

What you get

Everything a signing workflow needs, nothing it doesn't

Send in minutes

Upload a document, drop fields where they belong, and send. No template required for a one-off — or save it as one for next time.

AI-suggested fields

Upload a document and get signature, date, and text fields proposed automatically from what's actually on the page. Confirm or adjust before sending.

Built-in audit trail

Every open, view, and signature is logged with a timestamp, IP address, and location — bundled into a Certificate of Completion with each finished envelope.

Real PKI signatures

Signed documents carry an embedded, tamper-evident digital signature — not just a database record that says 'signed'.

Team workspaces

Invite your team, assign roles, and manage who can send, view, and administer — all scoped to your workspace.

API & webhooks

Everything in the product is also available as an API, with webhooks pushing status updates the moment something changes.

How it works

From upload to signed, in order

01

Upload your document

Drop in a PDF — offer letters, NDAs, contracts, policy acknowledgments, anything that needs a signature.

02

Place your fields

We suggest where signatures, dates, and other fields belong. Adjust anything, add what's missing.

03

Send to your recipients

Add names and emails, set a signing order if it matters, and send. Each person gets a secure, no-login-required link.

04

Track it to completion

Watch status update in real time, and get a Certificate of Completion the moment everyone's signed.

Security & compliance

Defensible from the first envelope

Tamper-evident signatures

Every signed PDF carries a real embedded digital signature, not just a database flag.

Full chain of custody

Every view, open, and signature is logged with timestamp, IP address, and location — bundled into a Certificate of Completion.

Workspace isolation

Every account is scoped to its own workspace — your documents and data never mix with anyone else's.

For developers

Built for teams and integrations alike

Everything you can do in the product — sending envelopes, managing templates, checking status — is also available as an API, with HMAC-signed webhooks so your own systems stay in sync automatically.

Questions

Frequently asked

Do my recipients need an account?

No. Anyone you send a document to signs through a secure link — no login, no account creation.

Is a signature made here legally binding?

Yes. Every signature is captured with full audit metadata (timestamp, IP address, verification method) and the signed document carries an embedded digital signature.

Can I use my own branding?

Yes, on eligible plans — replace the default header on your recipients' signing pages with your own logo.

What happens to my data if I leave?

You can export your full workspace data at any time from Settings, and request deletion whenever you'd like.

Do you have an API?

Yes — every core action (creating envelopes, checking status, managing templates) is available via API, with webhooks for status changes.
