Identifies as AIYour agent always says it's an AI assistant. Never a human impersonation.
Human escalationAnything sensitive routes to a human. Never improvised.
Measured on resolutionWe report whether needs were resolved, not message counts.

The hire math

One hire, or a front desk that never sleeps?

A full-time receptionist runs about $4,000 a month once wages, taxes, and benefits are counted — and still goes home at five, takes lunch, and calls in sick.

$149/mo

LedgerLine After-Hours is roughly 4% of the cost of that hire — covering every night, weekend, and holiday your office is closed.

How it works

Live in three steps

1

The Audit

We watch two weeks of your calls and messages and show you exactly what you're missing — free, no obligation.

2

The Build

We build your site and train your agent on your pages, prices, and policies. You approve everything before it speaks to a single customer.

3

The Answer

Your agent goes live — answering, booking, and capturing leads around the clock, with humans one step away for anything sensitive.

Frequently asked questions

The five questions every firm should ask an AI vendor

We answer them in writing, in every proposal:

View All FAQs →
1What can it see?+

Only the knowledge base you approve — your pages, hours, prices, and policies. Nothing else.

2What can it decide alone?+

Routine answers and bookings. Anything sensitive, financial, or legal is escalated, never improvised.

3What does it escalate?+

Anything sensitive, financial, or legal — plus anything outside the approved knowledge base — routes to a human.

4How is it measured?+

We report resolution rate — whether the customer's need was actually resolved — not message counts.

5Who can stop it?+

You can shut your agent off at any time, instantly.
