01

Pick a template

Start from your own engagement letter, editable and reusable for every client.

02

Client e-signs

One link. A signature with a timestamped audit trail, valid under ESIGN and UETA.

03

Invoice gets paid

The invoice sends on signature and collects payment. Reminders go out on their own.

The onboarding scramble

Every new client is the same manual grind.

Rewrite the letter, email it, chase the signature, remember to invoice, then chase the payment. The all-in-one suites fix it, if you will pay per seat, sign an annual contract, and spend a weekend learning them.

Engagement letter #10. The same document, rebuilt by hand for every single client.

Signatures that stall. Work starts before the letter is signed, and the liability sits with you.

Invoices sent late, paid later. The billing step is an afterthought, so the cash comes slowly.

Suites built for teams. Per-seat pricing and twenty modules you will never use, to send one letter.

What you get

One clean flow, from letter to paid.

Reusable engagement letters

Bring your own attorney or insurer-approved letter, then reuse it in a click. Editable starting points, not legal advice.

One-link e-signature

Your client signs from a single link, with a timestamped audit trail. No account for them to create.

Auto-invoice on signature

The moment the letter is signed, the invoice sends and collects payment through Stripe.

Payment reminders, handled

Gentle reminders go out automatically until the invoice is paid, so you never chase again.

No per-seat pricing

Flat. Every person in your firm is included. You are never punished for growing.

No annual lock-in

Month to month, cancel anytime, and export your data in one click whenever you want.

The founding guarantee

Try it with nothing at risk.

Onboarding a client should feel lighter, not like another system to learn. If it does not, you should not pay for it.

  • 14-day free trial, no card to start
  • 30-day money-back after that, no questions asked
  • No annual contract, cancel anytime
  • Export your data in one click
  • Never pay per seat
