Sign and Return for Business.

Self-hosted e-signature software for service agreements, proposals, and client authorizations. For accountants, consultants, therapists, and other small professional practices that want signed paperwork back the same day — on their own hardware.

Your clients’ paperwork stays with you.

Sign and Return was built by a practicing attorney for his own law practice, and it treats your documents the way a law office must treat its files: they stay on your machine. The email your client receives carries only a link — the document itself never leaves your instance. When they sign, the signed PDF and its record are written to your computer, and nowhere else.

This is the same software the attorney version runs — not a lighter edition. The Solo and Firm tiers below differ in one thing: whether more than one person can send, and the supervision structure that comes with it.

Every signed document comes back with a signing certificate that records:

  • N
    Who signed, and when
  • N
    Every send, view, and signature event, with time and IP address
  • N
    The signer’s consent to do business electronically, captured before signing
  • N
    A SHA-256 fingerprint of the signed document — a later change to the file will no longer match it
  • N
    Your business’s name and details as the issuer

How it works.

1. Prepare

Upload a PDF — a service agreement, a proposal, an intake or authorization form — and place the fields your client must complete.

2. Send

Your client gets an email with a single-use signing link that expires. The email carries the link, not the document.

3. They sign

No account, no app, no password. They open the link on a phone or computer, consent to do business electronically, and sign.

4. You keep the record

The signed PDF returns to your instance with its certificate and audit trail — stored on your hardware, exportable at any time.

Self-hosted means you run it.

Sign and Return is software you install, not a website you sign into. It runs in Docker on a Windows, Mac, or Linux machine — setup takes about twenty minutes and assumes no technical background.
Your computer holds the records, so backups are yours to make, and the machine needs a public web address so your clients’ phones can reach their signing links.
If that trade — a little administration in exchange for full custody of your clients’ paperwork — sounds right to you, this was built for you.
