Know how every location answers the phone.
Knockler calls each of your stores, departments or call-centre lines like a customer would, every week. It asks what your customers really ask, then shows you who picked up, what they said and how well the call went.
From $29 a location a month. Only your own numbers, with your consent, and the caller never pretends to be a person.

You can't be on the phone at every location.
A customer who can't get an answer calls someone else, and you rarely hear about it.
Calls ring out
The lunch rush, a short-staffed afternoon, or a line that goes straight to voicemail.
Answers vary by store
One location knows the price and the hours. Another has to go check, or gets it wrong.
AI receptionists go unchecked
More calls are being answered by software and phone menus. Someone should be listening to what they tell your customers.
Mystery shopping, or QA for the lines you run.
Mystery shop every location
A call a week to each store or department, asking about hours, prices, stock or an appointment. See which locations pick up, which give the right answer, and which follow your phone standards.
Test your call centre or AI receptionist
Call your own lines from the outside, through the menus and holds a customer sits through. Check that people and AI agents give the right answers and get the job done, such as offering a booking.
The calls your customers make.
Write the questions your customers ask and the standards you expect. A few examples:
Auto service
"How much for a synthetic oil change, and can you fit me in Thursday?"
Tests: a clear price, asking about the vehicle, offering to book.
Hotels
"Do you have a king room for two nights next weekend, and is parking included?"
Tests: rates and availability, upselling, offering to reserve.
Restaurants
"Can you take a table for six on Saturday, and do you have gluten-free options?"
Tests: picking up at busy times, menu knowledge, taking the booking.
Retail and big-box stores
"Do you have this in stock, and how late is the store open tonight?"
Tests: checking stock, transfers between departments, hold times.
Call centres and AI receptionists
"I need to move my appointment to next week."
Tests: getting through the menu, the right answer, finishing the task.
Something else?
If customers phone you, Knockler can call too. Write your own questions and standards.
Real calls, on your schedule, at every location.
Add your locations, questions and standards
Enter each store or department's number, or import a spreadsheet. Write the questions customers ask, and the phone standards staff should meet.
We call like a customer would
Calls land at an unpredictable moment inside the hours you choose, and nobody can see when the next one is coming. The questions stay the same from week to week, so a change in the score is a change in how the phone was answered.
See exactly what happened
Results in minutes, not weeks: a quality score for every call, each question next to the answer it got, the transcript and recording, and what needs attention.
Evidence, not a gut feeling.
Every location gets the same questions and is held to the same standards, so you can compare them fairly, whichever phone system each one uses.
- One call-quality score, from the answers, your standards, tone and speed to answer
- Whether the call was answered, how long that took, and whether a person or an AI picked up
- Each question with the answer it got, checked against the answer you expect
- Which of your standards were met, and how the person came across
- The full transcript and recording
A call every week, for about the price of one human shop.
| Human phone shops | Knockler | |
|---|---|---|
| Price | Typically $25–75 a call | $29 a location a month, for a call every week |
| How often | Usually once a month or once a quarter | Every week, or every day |
| Results | A report one to three weeks later | Minutes after each call |
| Consistency | Depends on the shopper and the evaluator | Same questions and standards at every location, every time |
| Evidence | Varies by provider | Recording and transcript for every call |
Human prices are from mystery-shopping firms' published rates in 2025–2026, in USD.
Only calls you've authorized.
Knockler is for testing your own locations. The limits below are built into the product.
Consent first
Calls only happen once the business has accepted our Phone terms. Without that, every call is refused.
Real business lines
Each number is checked against public business listings. Anything else needs our approval before it can be called.
Honest about being AI
The caller never claims to be human. If someone asks, it politely ends the call.
Locations, not people
We score how each location answers, never named employees. The point is to fix the process, not to catch someone out.
Questions
Can staff tell the caller is AI?
Sometimes, and that's fine: it's testing the answers and how the call is handled, not trying to trick anyone. You choose for each location whether it says up front that it's an automated call. It never claims to be a person.
Is recording the calls legal?
Before any calls, the business confirms that its staff have been told calls may be tested and recorded. Where the law requires everyone on a call to agree to recording, that notice matters, and you can also have the caller say up front that the call is automated.
Will it book anything or give out details?
No. A booking call goes as far as picking a time, then stops before anything is booked. It never buys or agrees to anything, and never gives a real name, phone number, email or card.
Can we use it on other businesses?
No. Knockler only calls numbers that belong to your own locations.
Can we cancel?
Yes, any time. Plans are monthly unless you choose to pay yearly.
