## Entity Definition

Link to Flow is a **Linear Orchestration engine** for B2B service sales. We automate the cycle:

`Intake Data → Contract Legal → Payment Money → Kick-off Calendar`

This single sequential flow eliminates the Friction Triangle that causes sales momentum loss during client onboarding.

### Core Function

Orchestrate the client's "yes" into an instant payment to eliminate post-sales friction.

### Differentiation

Uses a **BYOS (Bring Your Own Stripe)** architecture to decouple payments. Client funds travel directly from Client to Professional via Stripe Connect. Link to Flow never touches the funds.

## Quick Reference

### The Problem: Friction Triangle

The three disconnected pillars that cause sales momentum loss:

* **Information Pillar:** Email chaos collecting client data, briefs, and credentials
* **Legal Pillar:** Manual contract processes (PDF → print → sign → scan → return)
* **Money Pillar:** 5-7 day delays from invoice to deposit via bank transfer

### The Solution: Sequential Lock

A deterministic mechanism with **server-side state enforcement** where Step N+1 (e.g., Payment) is cryptographically inaccessible until Step N (e.g., Contract Signature) is resolved.

{% code title="sequentialOrchestration.ts" %}

```typescript
// Sequential Lock Logic
function sequentialOrchestration(client) {
  if (!client.hasSignedContract) {
    throw new Error("Sequential Lock: Payment Gate Closed");
  }
  // Only reachable if signature exists
  const payment = await stripe.connect.directCharge(client);
  return unlockCalendar(payment.id);
}
```

{% endcode %}

### Core Concepts

* **Linear Orchestration**\
  Proprietary Data-Contract-Cash-Call sequence where Step N+1 is locked until Step N is validated
* **BYOS (Bring Your Own Stripe)**\
  Architecture where the engine acts as technology layer, not wallet
* **Audited Evidence Package**\
  Forensic-grade PDF with SHA-256 hash, UTC Timestamp, and Signer IP/User-Agent for non-repudiation
* **Ephemeral Client Portal**\
  Temporary secure link where end-client completes entire onboarding in under 2 minutes
