Auto-place
The end of dragging boxes.
Upload any PDF. Auto-place finds every signature line, date, initial and blank, and assigns each one to the right signer. Next time, “same as template” reuses a layout you already approved.
- Every field on every page — signatures, initials, dates, names, checkboxes and blanks
- Assigned to signers from the parties named in the document
- The same call your agent makes — in the dashboard, the API and MCP
- A full designer when you want one — snap, align, conditional fields and formulas, embeddable in your product

Agents
Agents that prepare, send and monitor — and sign with permission.
Connect any agent over MCP or the API. It can do everything you can do in the dashboard, under the same limits, with its own identity, budget and kill switch.
Review, then send
Sends you a review link with every field marked, who signs in what order, the email they get and what it costs. Approve, edit or reject in one tap.
Monitor
Watches every request live: who opened, who signed, what bounced, what changed since yesterday. Sends reminders and fixes delivery problems.
Sign with permission
Offers you a one-tap signing link — or signs for you under a permission you granted once, scoped and revocable. The certificate says so, and you’re told every time.
Connect in one line
A hosted MCP server with OAuth, or a local package with an API key.
Every action is audited (“prepared by agent X for Y”), every charge is listed under Agents › Activity, and document text reaches the agent marked as untrusted.

The API you’d have designed yourself.
Typed variables, predictable errors, and the details other platforms make you build: idempotency keys, dry runs, test mode, webhook replay.
- One call from template + data to a ready-to-sign envelope
- 422s that tell you exactly what to fix — with a JSON Pointer for every error
- Short-lived embed sessions minted when your page renders
- Free, unlimited test mode with
bf_test_keys - Every API operation as an agent tool, generated from the OpenAPI document

Sub-accounts for your customers, an embeddable designer and shared templates — on every plan. What unlocks them is trust, not a bigger contract. White label is included on Scale and an add-on on Team and Business.
Sub-accounts
A workspace per customer, linked to yours, with shared templates and brand profiles.
White label
Your name, colours, sending domain and signing hostname — no Bona Fide marks. Included on Scale and Enterprise, $99 a month on Team and Business.
Embedded designer
The template designer, auto-place included, as a web component in your app.
Bulk send
Thousands of personalised requests from one template and a CSV or an API call.
Limits grow as your workspace earns trust — a verified card, your own domain, a clean sending record — the same on every plan.

Questions
Good questions, straight answers.
What does “every feature, free” mean?
Free workspaces get the same product as paid ones: the API, MCP, agents, auto-place, sub-accounts, brand profiles, bulk send and the test sandbox. Paid plans add volume, SSO and enterprise controls. White label is paid: included on Scale and Enterprise, $99 a month on Team and Business. Some features unlock as your workspace earns trust, the same way on every plan.
Can an agent sign on my behalf?
Only if you allow it. By default your agent sends you a one-tap signing link. You can instead grant a permission — for one request, a template, a counterparty or more — with an expiry, and revoke it any time. You’re notified every time, and the certificate records that the agent signed for you under that permission.
Are Bona Fide signatures legally binding?
Bona Fide workflows are built to the requirements of the US ESIGN Act and UETA and to simple electronic signatures under eIDAS: consent to do business electronically, clear intent to sign, signer attribution, and a tamper-evident record kept for you. As with any e-signature provider, a few document types are excluded by law in some places — for example wills, some family-law and court documents, and anything that must be notarized or filed on paper. Qualified signatures for the EU and country-specific schemes are available as add-ons through accredited providers.
Why do limits depend on trust instead of my plan?
E-signature emails are a favourite disguise for phishing. New workspaces start with modest sending limits that grow when you verify a card, authenticate your own domain and build a clean sending record, so honest senders get room quickly and abusers don’t. The Usage & limits page shows every limit and how to raise it.
What does “verifies green” mean?
Every completed document is sealed to PAdES (ETSI EN 319 142) with RFC 3161 trusted time and embedded long-term validation data. Open it in Adobe Acrobat and it validates — and any change after sealing is detected. You can also verify any copy at bonafidesign.com/verify.
What counts as an envelope?
A set of documents sent for signature to one or more people. You are billed only when it is completed — never for drafts, declines, or voided envelopes.
Can I move from DocuSign?
Yes. Upload your PDFs and let auto-place put the fields on them — or ask your agent to. Your existing integrations map cleanly to our envelope, recipient and template model.
Do I need a credit card to start?
No. The free plan includes the full API and 100 completed envelopes every month. Add a card only when you want more.
Which languages do signers see?
Signers can sign in any of 50 languages, including right-to-left Arabic, Hebrew, Persian and Urdu. You choose a language for each recipient, or Bona Fide uses their browser’s. Emails, the signing page and the consent text all follow it.
