Why a Dedicated Workflow Matters

If you're a developer, freelancer, or agency building AI voice solutions for clients, you need a workflow that lets you configure everything before handing off access. Kestrel supports this with a simple approach: one account per client, configured by you, handed off with a single invitation.

Step 1: Create the Account

Sign up at kestrelvoice.com/signup using a dedicated email for this client engagement. Each Kestrel account has one owner at creation time, so a separate sign-up per client keeps each client's data and configuration fully isolated.

Step 2: Configure the AI Agent

Go to /settings/ai-agent and set the greeting, business hours, call routing, and voice instructions. These settings are configured on the account itself and don't require a phone number to be attached first.

Step 3: Pick a Phone Number

Navigate to /settings/phone-numbers to search and purchase a specific number for your client. Do this before activating billing so the number is ready when the plan goes live.

Step 4: Activate Billing

Choose and activate a plan directly from /settings/billing. Activating a plan while signed in as the account owner is a direct checkout — your client never has to go through onboarding themselves.

Step 5: Invite the Client

Go to /team and create an email-scoped invitation for your client. Share the invite link with them.

Step 6: Client Accepts Access

Your client sets a password (or signs in) and lands directly on the configured dashboard, skipping onboarding entirely.

Continuous Support: What You Can Do After Handoff

Setup isn't a one-time event. Because you (or your client) keep access to the account, ongoing tuning is just as real a part of the workflow as initial setup.

AI Training Hub

/settings/ai-training tracks extraction patterns the AI has learned from real calls, with an approval queue for new patterns and a configurable confidence threshold before something is auto-applied.

RAG Content / Knowledge Base

/rag/content manages the website content the AI draws on to answer questions. You can add sources, trigger a rescrape after your client updates their website, and refresh what the AI knows without touching its core configuration.

Voice Instructions and Call Routing

Both are editable at any time from Settings — if a call reveals the AI mishandled a specific phrase or should route a new type of request differently, update it directly and the change applies to the next call.

Why This Matters

A client who gets handed a working AI phone agent and just sets a password feels like they hired an expert. This workflow keeps you in control of the configuration while giving your client a clean, single-step way in.
