What's in the Heyline resource library?
Four free pages and a blog. One explains what an AI receptionist is, one does the arithmetic on the calls you miss, one carries the forwarding codes for US and Canadian carriers, and one defines the words. Nothing here is gated: no sign-up, no card, no phone number.
One box on this site arrives already filled in: the calculator's booking rate, set to 42% from ServiceTitan platform data covering 3,000+ US and Canadian trade shops in 2022. Every other field starts empty, because your call volume and what a job bills are yours, not an average's.
Each page shows the day it was last updated and names the source behind any number that did not come from the product itself. Nothing here asks for an email address first.

What should I read on the blog?
Eight posts, four themes. They go wider than these pages do — the subject, not just Heyline.
| Theme | Posts | What you get |
|---|---|---|
| What it costs | AI receptionist pricing · Answering service cost | What the market charges by the month, by the minute and by the call. |
| Nights and weekends | 24/7 AI answering · After-hours answering services | Who picks up at 2 AM, and what covering that hour costs. |
| By trade | HVAC answering service · Cleaning service scheduling | How the phone really runs in two trades: dispatch, recurring cleans, seasonal spikes. |
| Booking and choosing | Scheduling with Google Calendar · Best AI receptionist for small business | How booking over the phone works day to day, and how to weigh the tools that do it. |
The rest of the archive is on the Heyline blog.
Where do these fit next to the rest of the site?
These pages explain. The rest of the site specifies. Features lists what she does on a call and what she refuses to do, pricing has the three plans and the minutes, compare sets her beside other AI receptionists with every price dated, and how it works walks it from a pasted website to an answered phone.
Or skip the reading. Give her your website address and, about sixty seconds later, hear how she answers your callers — free, no card, and no number involved yet.
What these pages won't do
The calculator multiplies numbers you type in. That is arithmetic, not a forecast, and it assumes a call you missed would have booked as often as one you answered.
The forwarding guide carries your carrier's codes, not ours. What they charge for the feature, and what they call it, is theirs to change — so the page names the day each code was last checked.
And none of it decides anything for you. Whether she sounds right on your line is not a question reading can settle. Talk to her instead, and find out.
Frequently asked questions
Where do the calculator's defaults come from?
One box arrives filled in: the booking rate, at 42%. It comes from ServiceTitan platform data gathered in 2022 from more than 3,000 trade businesses across the US and Canada, where the typical shop booked 42% of its inbound calls and shops under five technicians booked 24%. Type your own over it.
Which page should I open first?
Start with the definitions page if the category is new to you. If you already know what these things are and want a number, open the calculator. If you have decided and want the calls you miss tonight to reach her, the forwarding guide gets you there. The glossary is for the word you trip over on the way.
What's on the blog that these pages don't cover?
Longer reading, and a wider subject. The four pages here answer questions about Heyline. The blog covers the market around it: what answering services charge, how shops in one trade run their phones, how scheduling on a shared calendar behaves day to day. The eight grouped above are the ones worth your time first.
How current is any of this?
Every page prints the day it was last updated at the foot, next to the sources behind its numbers. The carrier codes were last cross-verified on July 17, 2026. The booking-rate figure is ServiceTitan's from 2022, and it carries that year everywhere it appears, because an undated number is a rumor.
