OneSign · E-signing

E-signing built for accounting documents

Send engagement letters, tax returns and declarations for signature — and OneSign already knows whose document it is, where to file it, and which job it finishes. Not a generic signing tool bolted on; e-signing that understands an ITR from an engagement letter.

Drop a document in. It does the rest.

It reads the document

OneSign identifies the document type and reads the names on it, so it can work out who signs and where the signature belongs — placing fields for you.

It matches the client

The signer's email resolves from the client's own record. A confident match is ready to send; anything less waits for you to confirm rather than guessing.

The client signs

A branded email links them to a clean signing page — on any device, with an optional one-time code for extra assurance. They can even ask a question back instead of signing.

It files and finishes

The signed PDF files itself to the client's folder, and the matching job advances on its own — so "signed" and "done" happen in the same moment.

The details generic signing tools miss

OneSign was built inside an accounting practice, so it handles the things a general e-signing product never has to think about:

Packs for a family group

Several returns for several people go out as one pack — and each declaration is addressed to the right person, not whoever's listed first.

Sign in office, or on paper

A reception iPad for clients who came in, and a way to record a document signed on paper — so the queue answers "what's signed but not yet lodged?"

It signs the client's part, never the firm's

The tax agent's certificate is the firm's to sign — OneSign never auto-places a client signature on it. The right person signs the right line.

Sign before the client exists

An engagement agreement is signed before someone becomes a client — signing it is what makes them one. When they convert, the document follows onto their record.

A bounced email or an unread question doesn't go quiet. A dead address surfaces with a "fix email" prompt, a client's question lands as staff work with somewhere to reply, and reminders are the same email said again — never a different-looking message that invites doubt.

Part of the practice, not another login

Every signature lands on the client record — sent and signed appear on the one timeline with their calls, emails and jobs.
Your firm's wording and logo — the signing email and page carry your brand, with templates for the messages and field layouts you send often.
Schedule a send — sign your part now, hold the client's email for a chosen time.
One less subscription — replaces a standalone e-signing tool, with none of the copy-paste between systems.

Frequently asked

Anything you send — engagement letters, tax returns, declarations, deeds. The client gets a branded email linking to a signing page they can use on any device, with an optional one-time code for added assurance. They can also type an answer into a field or ask a question back instead of signing.

Yes. On completion the signed PDF files to the client's folder, and the matching job advances — so signing and finishing the job happen together, with nothing to move by hand.

Yes — there's a reception iPad flow for in-office signing, and a way to record a document that was signed on paper, so the queue always reflects what's actually been signed, however it happened.

That's the idea. Because OneSign lives inside OneHQ, it knows your clients, files to their folders and moves your jobs — so it removes both the subscription and the copy-paste that a standalone signing product leaves behind.

Signed, filed, and the job's done.

E-signing that understands your documents, your clients and your workflow.
