Your SDR Agency Is Not Performing: How to Diagnose It Before You Cancel

Before you cancel an SDR agency, find out where the problem actually is. Underperformance sits in one of five places: the list, the messaging, the callers, the qualification, or your side of the engagement. Three of those five are fixable in two weeks. Two of them mean you should leave. Cancelling without knowing which one you have means you will hire the next agency, hand them the same inputs, and get the same result.

This guide gives you the diagnostic, in the order to run it, with the numbers that point to each cause, the fixes, and the signals that mean exit rather than repair. It applies whether you are three weeks in or six months in.

TLDR

1. Pull the numbers. Dials, connects, conversations, meetings booked, meetings held, opportunities. If the agency cannot supply these weekly, that is the finding.
2. Locate the leak. Each broken stage points to one of five causes.
3. Fix list, messaging and qualification problems in two weeks. Caller problems need a substitution or an exit. Your side problems need honesty.
4. Exit on three signals: no conversations at Day 45 after a list rebuild; no recordings; caller substitution without consent.

Step 1: check the numbers, not the feeling

"It is not working" is a feeling. The numbers turn it into a diagnosis. Ask for the last four weeks of: dials, connects (decision maker reached), conversations (past the brush off), meetings booked, meetings held, and opportunities created by your AEs.

If the agency reports dials and emails but not conversations, or cannot produce weekly numbers at all, you have already found the problem. An agency that does not measure conversations cannot manage them. Our SDR metrics guide covers the benchmarks for each stage; the summary for Australian mid market phone first programs is connect 8 to 15 percent, conversation to meeting 15 to 25 percent, show 75 to 85 percent, meeting to opportunity 40 to 60 percent.

Step 2: locate the leak

Place 1: the list

Symptoms. Connect rate under 6 percent. Wrong numbers, switchboards, gatekeepers. Titles outside the agreed list. Existing customers or open opportunities being called.

Cause. A database export instead of a built list. Thin Australian mobile coverage. No suppression file. Stale data.

Fix. Rebuild with verified mobiles and direct dials for senior contacts, add suppressions, tighten the ICP to fewer, better accounts. Two weeks. Our guide on who builds the prospect list covers what a real list contains.

Place 2: the messaging

Symptoms. Connect rate healthy. Conversations short. Conversation to meeting rate under 10 percent. Objections logged are all the same ("not interested", "send me something").

Cause. An opener that leads with the company name and a pitch. No question in the first thirty seconds. An ask for a demo instead of a conversation.

Fix. Listen to ten recordings with the agency. Count the seconds before the caller asks the prospect a question about their world. Rewrite the opener to lead with need. Test two variants for a week. One to two weeks. Our cold calling mistakes guide covers the common failures.

Place 3: the callers

Symptoms. Recordings reveal script reading, no ability to answer the second question, unfamiliarity with the Australian market. An accent or time zone mismatch you were not told about. Different voices week to week.

Cause. A shared pool where you were sold a dedicated team. Offshore delivery where you were sold Australian. Junior callers on a senior buyer list.

Fix. Demand a named caller change, in writing, with the new caller briefed and in your weekly review. If the agency will not, or cannot without moving you offshore, this is an exit signal. Our dedicated vs shared pool comparison covers the questions that reveal the model.

Place 4: the qualification

Symptoms. Meetings booked at a reasonable rate. Show rate under 65 percent. Meeting to opportunity under 30 percent. Your AEs describe meetings as "polite but pointless".

Cause. No written qualified meeting definition, or one that is not enforced. Meetings framed as demos to end the call. Booked two weeks out. No confirmation the day before. Empty handover.

Fix. Write the four tests (person, company, need, attendance) into the engagement with a replacement remedy. Book within seven days. Confirm the day before. Require a confirmed, inferred, unknown handover note on every booking. Two weeks to see the effect. Our guide on how an outbound agency should define a qualified meeting has the template.

Place 5: your side

Symptoms. Meetings held ten days or more after booking because your AEs' calendars are full. No feedback given on meeting quality. ICP changed twice in eight weeks. AEs running meetings as demos. The weekly review skipped three times.

Cause. Internal capacity and attention. Roughly a third of underperforming engagements sit here, and no agency will tell you.

Fix. Honest and internal. Take meetings within five days or accept fewer of them. Give written feedback on every meeting for a month. Hold the ICP steady for a full quarter. Turn up to the review.

The diagnostic worksheet

Fill this in before the conversation with the agency. It takes twenty minutes and it turns a complaint into a diagnosis.

Mark each row green, amber or red. The pattern of reds tells you which of the five places the problem sits before anyone has to defend anything.

Three illustrative diagnoses

Hypothetical cases, showing how the worksheet resolves.

Case one. Connect rate 4 percent, everything downstream inside range on the small volume that gets through. Recordings good. Same callers. Diagnosis: list. The agency is calling switchboards and stale numbers. Fix: rebuild with verified mobiles, tighten the ICP, re run for three weeks. Fixable.

Case two. Connect rate 12 percent, conversation rate 45 percent, conversation to meeting 7 percent. Recordings reveal the caller opening with the company name and a two sentence pitch. Diagnosis: messaging and possibly caller. Fix: rewrite the opener to lead with a question, review ten calls a week for three weeks. If the caller cannot deliver the new opener, substitution. Usually fixable.

Case three. Connect and conversation rates healthy, meetings booked at 18 percent of conversations, show rate 58 percent, meeting to opportunity 22 percent. AEs describe meetings as pleasant and pointless. Diagnosis: qualification and framing. Meetings are being booked as demos with people who agreed to end the call. Fix: four test definition, book within seven days, confirm the day before, handover note on every meeting. Fixable in two weeks, and the agency's willingness to adopt it tells you whether to stay.

Having the conversation with the agency

Raising underperformance well gets it fixed. Raising it badly gets defensiveness and a slow exit. Five practices.

Bring the worksheet, not the feeling. "Connect rate has been 4 percent for four weeks against a benchmark of 8 to 15" is a conversation. "It is not working" is a fight.

Ask for their diagnosis first. A good agency has already seen the numbers and has a view. If they have not, that is a finding too.

Agree one fix and one checkpoint. Not five fixes. One change, two or three weeks, a specific number that will show whether it worked.

Ask for the recordings in the same meeting. If they are offered without hesitation, you are dealing with a provider who manages quality. If they are not, you have your answer.

Write it down. A short note after the call: the diagnosis, the fix, the checkpoint date, the number. Sent to the agency. This is what you will refer to at the checkpoint, and it is what protects you if the engagement ends.

Rebuilding trust after a fix

If the fix works, the relationship is often stronger than before, because both sides have seen the other respond under pressure. Three things keep it that way.

• Keep the weekly review, with the caller present, even when the numbers are good.
• Keep the worksheet running monthly. Programs drift slowly.
• Say so when it is working. Agencies allocate their best people to the clients who engage.

Step 3: the checkpoints

Three dates that tell you whether the fix is working.

Day 45. There should be conversations. Not many meetings yet if calling started at week two or three, but conversations at a healthy connect and conversation rate. If there are almost none after a list rebuild and adjusted call windows, the market is not reachable by phone or the agency cannot reach it. Either way, stop.

Day 60. Meetings should be converting to opportunities. If they are held and none are becoming pipeline after a qualification and handover reset, the ICP is wrong or the agency is booking the wrong people. Reset before month three.

Day 90. Every stage inside benchmark, or a credible explanation and a fix underway. Otherwise decide. Our guide to the first 90 days sets out what each phase should produce.

For engagements past 90 days, run the same logic on a rolling four week window.

Step 4: when to exit

Three signals, any one of which is sufficient.

1. No conversations at Day 45 after a rebuilt list. The channel or the provider is wrong for your market.
2. Refusal to share recordings. An agency that will not let you hear the calls cannot be quality managed. There is no fix for this.
3. Caller substitution without consent, particularly offshoring a program sold as Australian. This is a breach of trust and usually of the contract.

A fourth, softer signal: meetings consistently outside the qualified definition after two correction cycles. The agency either cannot or will not enforce quality.

Step 5: how to exit cleanly

Notice. In writing, per the contract. If you are on a fair contract, 30 days after the initial term.

Handover. The account list with all enrichment, all CRM records, call recordings or an agreed subset, messaging and sequences, and a short learnings document. Within ten business days. If the contract does not give you this, ask for it anyway; most agencies will hand over the list to protect their reputation.

Do not agree to a paid extension to "give it more time" without a specific fix and a specific checkpoint. Our SDR agency contracts guide covers exit clauses.

Step 6: what to do differently next time

Three things, all before the first call.

Define a qualified meeting in writing. Four tests, replacement remedy, recording review window.

Get caller location and names in the contract. With a no substitution clause.

Start weekly reviews from week one. With the caller in the room and recordings on the table.

Most second engagements succeed where the first failed, not because the second agency was better, but because the buyer knew what to insist on.

How Nousu handles underperformance on its own programs

Nousu Collective runs the diagnostic above on every program every week, whether the client asks or not. Segments that do not produce are cut in the review. Openers that do not land are rewritten from recordings. Meetings that miss the definition are replaced. If a market is not reachable by phone, we say so and recommend a pause rather than continuing to invoice. See our solutions page for underperforming SDR programs.

The bottom line

An underperforming SDR agency is a diagnosis, not a verdict. Pull the six numbers, find the stage that is below benchmark, and you will know whether the problem is the list, the messaging, the callers, the qualification or your own side. Fix the fixable ones in two weeks. Exit on no conversations, no recordings, or callers swapped without consent. And write the qualified meeting definition and the caller clause into the next contract before anyone dials.

Inheriting a program that is not working, or trying to fix one mid stream? Book a 15 minute call and we will run the diagnostic with you, whoever the agency is.

Frequently asked questions

Why is my SDR agency not booking meetings? Usually one of five causes: a poor list (low connect rate), weak messaging (short conversations), the wrong callers (script reading, unfamiliar with the market), loose qualification (meetings that do not show or convert), or client side issues (slow meeting uptake, no feedback, shifting ICP). The stage where your numbers fall below benchmark tells you which.

How long should I give an SDR agency before cancelling? Hard checkpoints at Day 45 (are there conversations?) and Day 60 (are meetings becoming opportunities?), with a decision at Day 90. For older engagements, the same logic on a rolling four week window.

What should I check if my lead generation agency is underperforming? Weekly numbers at every stage (dials, connects, conversations, booked, held, opportunities), call recordings, the qualified meeting definition, caller location and continuity, and your own team's meeting uptake and feedback.

Can an underperforming SDR campaign be fixed? List, messaging and qualification problems usually can, inside two weeks, with a rebuild, an opener rewrite and a written definition. Caller problems need substitution or exit. Client side problems need internal change.

How do I exit an SDR agency contract? Give written notice per the contract, request the full handover (list, CRM records, recordings, messaging, learnings) within ten business days, and decline paid extensions that do not come with a specific fix and checkpoint.

What is the first thing to check when an SDR agency is underperforming? Connect rate. If it is under 6 percent, the list or the call windows are the problem and nothing downstream can be judged. If connect rate is healthy, move down the funnel: conversation rate points to the opener, meeting rate to the ask, show rate to framing and confirmation, opportunity rate to qualification and handover.

How should I raise underperformance with my SDR agency? With the stage by stage numbers against benchmark, not with a general complaint. Ask for their diagnosis first, agree one fix and one checkpoint with a specific number, request the recordings in the same conversation, and write the agreement down afterwards.
