You run a one-person business; the agent runs the paperwork. A client call or a written brief goes in, a signed SOW with the deposit already in your own Stripe comes out, and the only human step is you reviewing it on your phone.
Claude to draft, LetSign to sign and collect, your own Stripe to get paid. The recorder is a bonus, not a requirement: a written brief feeds the agent just as well as a transcript.
No SDK, no webhooks, no integration project. The stack runs on two connections and one prompt.
A client calls, or a brief lands in your inbox. If you sell on calls, Fathom, Granola or Fireflies turns the conversation into notes the agent can read; if the brief is written, you paste it straight into the chat. Either way, the scope, the budget and the names your client actually used are what the agent drafts from.
Point Claude at the notes and it authors the proposal through the LetSign MCP: the deliverables in the client's own words, the timeline, conditional pricing tiers if you offer packages, and a deposit due at signature. One proven opener:
"Draft the website redesign SOW for Mireille at Fernhollow Ceramics from her brief - fixed price with a 40% deposit due at signature, the rest on delivery - and stage it for my review."
The agent stages the SOW; nothing sends itself. You read it wherever you are, adjust a clause or the deposit if you like, and press send. The human send-gate is a feature of the stack, not a limitation.
Your client opens one public link, picks a package if you offered several, verifies their email and signs a binding e-signature. The deposit is collected in the same sitting. Remember: the sender never signs. The client does.
The charge runs through your own Stripe account: one-off deposit, subscription retainer or save-card-on-file for the balance. LetSign never holds your funds, and the payout follows your normal Stripe schedule.
This page is the recipe; the deep dives live one level down. If you sell as a founder rather than a freelancer, read the founder-led sales stack. For the payment mechanics, see how to get paid from an AI agent, and the full numbers live on the pricing page.
The deposit is collected at signature time, in the same link as the signature itself. There is no separate invoice to chase and no gap between yes and paid where the project can stall.
The SOW is drafted from the client's own brief, so deliverables, timeline and price are written down and signed before the work starts. When the scope is in the contract, the conversation about extras starts from the contract.
Client wants a smaller package or net-30 on the balance? Tell the agent; it updates the terms and restages the SOW for your review. No export, re-edit, re-send cycle.
And none of it locks you into the chat window: everything the agent drafts is fully editable by hand in the LetSign app, full parity with the MCP.
The recipe holds no matter which brand fills each slot. Swap freely; the LetSign layer and your Stripe stay put.
| LAYER | IN THIS RECIPE | SWAP IT FOR |
|---|---|---|
| The agent | Claude | Cursor, ChatGPT (requires Developer Mode) |
| The recorder | Fathom (optional) | Granola, Fireflies, or nothing at all: skip the layer and work from a written brief |
| The brief | Call notes | An email thread, a voice memo transcript, or bullet points you type into the chat |
No trial clock, no feature wall in front of the flow this page describes. You pay when payments run through it, or when the volume makes the paid plan cheaper.
Full MCP access, unlimited seats, and the whole motion on this page: SOW, conditional pricing, binding e-signature, payment into your own Stripe. LetSign takes a 0.20% fee on payments collected through it. For a freelancer starting out, this is the plan.
$19 per month until October 1, 2026, and that price is locked until October 1, 2028; the standard price after launch is $49. Paid plans pay 0% on payments up to $20,000 per month, then 0.05% above that. Worth it the month the fee math tips.
For most freelancers, yes. The Free plan is $0 with full MCP access and unlimited seats, and LetSign takes a 0.20% fee on payments collected through it. When your volume makes the math tip, the launch plan is $19 per month until October 1, 2026, locked at that price until October 1, 2028; the standard price after launch is $49. Paid plans pay 0% on payments up to $20,000 per month, then 0.05% above that.
No. The recorder is the one optional layer in this stack. If you sell on calls, Fathom, Granola or Fireflies turns the conversation into notes the agent drafts from. If your clients brief you by email or chat, paste the brief and the agent works from that instead.
You offer a deposit option on the proposal, and your client pays it at signature time: the same public link carries plan choice, email verification, the binding e-signature and the payment. The charge runs through your own Stripe account, whether it is a one-off deposit, a subscription or a card saved on file. LetSign never holds your funds.
You do. The agent drafts and stages the SOW, but nothing sends itself: you review every line, on your phone if you like, and press send. And the sender never signs; your client verifies their email and signs the binding e-signature on their side.
Install LetSign free, connect your Stripe, and let the agent stage the next SOW while you finish the actual work.
