No file starts without a signed client agreement.

Every client signs the same agreement before work begins. FirstInk sends it automatically on every new file, pre-filled and ready to sign on any phone, and keeps the file blocked until it's done.

Create an account
1

Upload once

Your client agreement, as PDF or Word. Confirm the detected fields and publish.

2

Open a file

Client name and email (or let your system or the client do it). The agreement goes out by itself.

3

Client signs, work starts

The file unlocks, the signed PDF and audit certificate are filed, everyone gets a copy.

Automatic on every file

Create a file (in the app, from your system via API, or by the client through your intake link) and the agreement is filled in, signed for the firm, and sent. Nobody types, emails or chases.

Works with your agreement

Upload your own PDF or Word document once. Signature lines, dates, initials and blanks are detected; adjust anything by drag and drop.

The gate

Files stay blocked until the agreement is signed. The dashboard shows what's blocked, what's overdue and how fast clients sign.

Signing clients actually finish

No account, no app. Works on any phone: consent, review, tap to sign, done. Automatic reminders every 3 days.

Evidence that holds up

The document is frozen and fingerprinted (SHA-256) when sent. Every step is in a tamper-evident, hash-chained audit trail appended to the signed PDF.

Fits your systems

REST API to create files, signed webhooks when an agreement is completed or declined, and a signed PDF you can download into your case file.

Security and legal

  • Valid e-signatures: built for the U.S. ESIGN Act and UETA (and basic electronic signatures under eIDAS): consent to electronic records, deliberate signing, a copy for the signer.
  • Tamper evidence: the document is fixed and hashed when sent; audit events are append-only and hash-chained; the certificate is part of the signed PDF.
  • Access control: every table is isolated per company in the database (row-level security). Documents live in private storage behind 5-minute links.
  • Signing links are 256-bit, expire, and only their hash is stored. Reissuing a link kills the old one.
  • Encryption in transit (TLS) and at rest (AES-256).

Not suitable for

  • Documents the law requires on paper or with a notary: wills, many family-law and court documents, certain statutory notices.
  • Protected health information (HIPAA): healthcare use needs a BAA, which isn't offered yet.
  • Qualified electronic signatures (eIDAS QES) or identity-verified signing (ID checks, SMS codes).
