10 Questions Before You Sign an Answering Service

Every contractor we talk to has the same answering service horror story.

The bill that mysteriously tripled in December. The agent who told a customer the wrong dispatch fee for six weeks before anyone caught it. The “24/7 coverage” that was actually outsourced overnight to a different time zone and a different vendor. The cancellation clause that turned into a 90-day fight.

These aren’t bad luck. They’re features of the answering service industry, which has spent two decades optimizing for vendor profit, not contractor outcomes.

If you’re shopping for an answering service — or auditing the one you already use — here are the 10 questions that separate the real partners from the contract traps. Ask them all. In writing. Before you sign.

1. Per-Minute or Per-Call Billing — And What Counts as a Minute?

This is the question that pays for itself.

Most answering services bill per minute. Some bill per call. A few bill a hybrid (per-call base + per-minute over a threshold). Every model has a different incentive structure.

Per-minute: The vendor makes more money the longer your calls take. Translation: the vendor has zero incentive to be efficient. Long hold times, repeated callbacks, drawn-out scripts — all good for them, bad for you.

Per-call: Predictable cost, but the vendor is incentivized to end calls fast. Translation: your customer might get rushed off the phone before booking.

Hybrid: Usually the worst of both worlds, especially with low base + high overage rates.

The follow-up questions that matter:

• Are minutes rounded up to the nearest full minute? (Most are. A 61-second call becomes a 2-minute call.)
• Does hold time count?
• Does the “after the customer hangs up” wrap-up time count? (At many vendors, yes — 30–60 seconds added to every call.)
• Are voicemail check-ins billed?

Audit one month of itemized calls. If the average call is over 4 minutes and you’re billing per minute, something is wrong.

2. What Are Your After-Hours and Holiday Upcharges?

The contract you sign in February will look very different in November.

Most answering services have surcharges for:

• After-hours (definition varies)
• Weekends
• Holidays (the list of holidays can be… creative)
• Storm or emergency periods (declared by the vendor)
• “Peak volume” times

Ask for the full surcharge schedule in writing. Make sure the contract specifies what counts as “after hours” (5 PM? 6 PM? 7 PM?) and what counts as a holiday (12 federal holidays? 18?).

Real example: one HVAC company we work with discovered their answering service was charging holiday rates on the day after Thanksgiving, Christmas Eve, New Year’s Eve, and the Friday before Memorial Day. Their December bill was 2.3x their July bill. That wasn’t volume. That was surcharge engineering.

3. Who Writes the Script — And Can We Change It?

Your script is your brand. If you can’t control it, you don’t have a brand on the phone.

Ask:

• Do we provide the script or do you?
• How often can we update it? (Some vendors charge per change. Some require 30-day notice.)
• Is the script enforced or “suggested”? (If you can’t audit compliance, it’s suggested.)
• Can the script include trade-specific intake questions?
• Can it include pricing guidance for common services?
• Can it include emergency triage criteria?

If the answering service tells you they have a “standardized script” and you can “tweak” it, walk away. Standardized scripts are designed for vendor scalability, not your conversion rate.

4. What’s the Average Tenure of Your Agents?

This is the question they don’t want you to ask.

Most call center turnover is brutal. Industry average is 30–45% annually, and some BPO call centers run 80%+. That means the agent representing your brand has likely been on the job for less than 6 months.

Compare that to your in-house CSR with three years of trade context. Now ask yourself which one is going to handle a complex plumbing diagnostic call better.

The follow-up questions:

• What percentage of your agents have been with you longer than 1 year? Longer than 3 years?
• Are agents dedicated to specific accounts or do they bounce between clients?
• How much training do agents get on home service trades specifically?
• Is HVAC vs. plumbing vs. electrical training differentiated?

If the answers are vague, expect vague results.

5. Do We Get Access to Call Recordings — And Are They Searchable?

Coaching, dispute resolution, training, and quality control all depend on this.

Ask:

• Are all calls recorded?
• For how long are recordings retained? (90 days? 1 year? Forever?)
• Can we download them or do we have to listen in the vendor’s portal?
• Can we search across recordings by keyword, date, customer name?
• Are transcripts auto-generated?

Most legacy answering services will give you a portal with limited search and no transcript. That makes coaching nearly impossible. Modern AI voice agents generate searchable transcripts for every call by default — a quiet but enormous difference.

6. What Do You Integrate With — And How Well?

The answering service that “integrates with ServiceTitan” might mean:

• (a) Bookings drop directly into your calendar in real time, with all details captured, OR
• (b) An agent emails your team a text summary that someone manually re-enters

These are not the same product.

Ask to see the integration working live. Have them book a job in front of you. Watch the data flow. Note exactly what fields populate automatically and what fields require manual entry.

Required integrations for most contractors:

• Field service software (ServiceTitan, FieldEdge, Housecall Pro, Jobber, etc.)
• Calendar (Google Calendar, Outlook)
• CRM (HubSpot, Salesforce if commercial)
• Texting platform (for confirmation messages)

If the answer to any of these is “we’ll work on it” or “Zapier handles that,” budget extra time and friction.

7. What’s Your Cancellation Policy — Exactly?

Read this clause five times before signing.

Things to watch for:

• Auto-renewal (most contracts auto-renew for another full term unless you cancel 60–90 days in advance)
• Early termination fees (can be 3–6 months of fees)
• Data export rights (can you take your call recordings, scripts, contact lists with you?)
• Phone number portability (some vendors hold your DID numbers hostage)
• Cooling-off period (rare, but ask)

If the cancellation clause is longer than the service description, you’re being set up to be stuck.

A reasonable cancellation policy: month-to-month after the first 30 days, with full data export rights and clean number portability. If the vendor won’t offer this, ask why.

8. Do You Offer Bilingual / Spanish Support — In-House or Subbed Out?

In most U.S. markets, a meaningful share of inbound calls are in Spanish or another language. The cost of dropping these calls is enormous.

Ask:

• Is bilingual coverage in-house or contracted to a third party?
• What languages beyond Spanish? (In some markets, Mandarin, Vietnamese, Tagalog, or Russian matter.)
• Is the bilingual agent the same person who answered the call, or is there a transfer?
• Does bilingual coverage cost extra?

A transfer to a third-party bilingual subcontractor is where calls die. Average drop rate during a transfer is 30%+.

9. What’s Your Emergency Escalation Protocol?

This is the question that protects your worst-case scenario.

For HVAC, plumbing, restoration, garage door, and several other trades, emergencies are revenue-critical — and life-safety critical. Mishandled emergencies are how contractors get sued.

Ask:

• What constitutes an emergency in your script?
• How is the on-call tech notified — text, call, app push, all three?
• What’s the time SLA between caller hangup and on-call tech notification?
• What happens if the on-call tech doesn’t acknowledge within X minutes?
• Is there a fallback escalation to a supervisor or backup tech?

Reasonable benchmark: live escalation to the on-call tech within 60 seconds of the call ending, with fallback to a second contact within 5 minutes if no acknowledgment.

If the vendor’s answer is “we leave a detailed message and the tech calls back,” that’s not emergency handling. That’s voicemail with extra steps.

10. What Does Your Reporting Actually Show?

Most answering service reporting is bad on purpose. The less you can see, the less you can challenge.

The metrics every contractor needs:

• Calls by hour, day, week, month
• Calls by call type (booking, emergency, general inquiry, status check, complaint)
• Bookings by call type
• Booking conversion rate (the most important number)
• Average call duration
• Hold time / dropped call rate
• Top reasons for unbooked calls
• Trends over time

If the reporting dashboard shows you “total calls” and “total bookings” and nothing else, you can’t manage what you can’t measure. Ask for a screenshot of the actual dashboard before signing. Vague answers here are a red flag.

The Real Question Behind the 10 Questions

Most contractors arrive at an answering service decision because their CSRs are overwhelmed and they need overflow coverage. That framing — “we just need someone to pick up” — is what makes contractors easy to overcharge.

The right framing is: “We need a phone experience that converts callers into booked jobs, captures revenue we’d otherwise lose, and never makes our brand sound worse than our CSRs.”

When you reframe it that way, the questions get sharper. The vendors who can answer them well are very few. And the gap between traditional answering services and modern AI phone platforms gets impossible to ignore.

Your script, your voice, your control. Searchable transcripts of every call. Real-time integrations. Sub-60-second emergency escalation. Month-to-month terms.

We’re not saying every contractor should use Caller. We’re saying every contractor should ask these 10 questions of whoever they sign with. Most won’t pass.
