AI Receptionist Buyer's Guide for Contractors

Start with your real call log

Count the calls your office misses and group the ones it answers. Repeated booking requests may suit a script. Quotes with unusual scope or a disputed invoice need a person. That split tells you whether to buy a human service, a packaged product, or a custom workflow. We have not shipped this yet, so if the custom route fits, we’d build it from your call examples rather than hand you one already deployed elsewhere.

Follow one routine call

Start with a call your office hears every day. The caller gives a name and service address, explains the job, and asks for a time. A narrow receptionist can carry that path when you define the questions and the available appointment types.

1. Answer on the business line. The opening identifies your firm and tells the caller that an automated assistant answered.
2. Collect the approved fields. The script asks for the details your office needs before it can book or return the call.
3. Check the next step. A standard job can reach the agreed calendar. Work that needs an estimate enters your current CRM with the caller’s own description.
4. Send named calls to a person. Safety terms and disputes leave the script as soon as they appear.
5. Write the record. Your office receives the caller’s details, the transcript, and the result through the tool it already checks.

Each step needs a failure route. A calendar can reject the booking. The CRM may be unavailable, or a caller may refuse a question. Decide what the assistant says in those cases before it takes live traffic.

Compare the running prices

JimmyAI at aiphonereceptionist.ca listed about $125/month with 50 minutes, then $0.25 per minute after that when checked 2026-08-28. It gives a small business a packaged script and a fixed product.

Smith.ai listed $300/month for 30 calls up to $2,100/month for 300 calls. Its published overage ran from $8.50 to $11.50 per call. Ruby Receptionist listed $250/month for 50 minutes up to $1,725/month for 500 minutes. Both sources were checked 2026-08-28.

Retell AI published raw components for a custom voice agent. Voice infrastructure sat near $0.055/minute, text-to-speech near $0.015/minute, and language models ranged from $0.003 to $0.16/minute. Telephony for a US number sat near $0.015/minute. Together, a typical call landed near $0.07 to $0.31 per minute when checked 2026-08-28 at retellai.com.

Those rates cover different things. Human plans include agent time and charge against calls or minutes. A packaged AI product adds its own script tools. Retell lists the parts that a custom workflow uses, so the build and later changes sit outside the per-minute amount. Use a recent call log to put the options on equal volume.

Test where a script fails

Background noise can turn a street address into the wrong job. A caller may also ask about a past invoice or describe a safety risk in calm words. Write a human route for those calls and test it with audio from the conditions your customers use.

Job-site audio deserves its own test set. Play calls recorded near traffic, fans, or running equipment when you have permission to use them. Read every captured address back to the caller before it reaches a booking.

Emergency handling needs rules written by your business. The assistant can listen for the agreed terms and transfer the call. A person decides what happens next. Include unclear descriptions in the tests because callers rarely use the same wording as your office.

Watch how the system behaves outside its script too. A supplier may call about a delivery, while an existing customer wants to challenge an invoice. The assistant should stop the intake and route the call with the conversation so far attached.

Choose a human when the call sells the work

A live receptionist can suit a contractor who receives a few detailed sales calls. Published human plans start inside the ranges above, and one comparison point ran from $250 to $720/month. Use the live service when a real conversation earns more than a repeated script saves.

Read several transcripts before you decide. If most calls need judgment about scope or price, a human has useful room to work. When the same intake repeats through a busy day, the script has a clearer job and its per-minute bill becomes easier to predict.

Ask the human service how its agents learn your trade terms and when they transfer. For an AI product, ask how you export transcripts and connect your calendar. A custom build only makes sense when the missing phone workflow matters enough to own.

Build one phone workflow

Our Missing Piece would connect one approved call flow to the phone system you already use. It can reach the agreed calendar or CRM, send hard calls to your team, and finish with a handoff document you own.

The build starts from your call examples and the access your phone provider allows. You approve the script, trigger terms, and acceptance checks. Hosting stays at cost within the published cap, while later changes use the published feature price.
