The report says pass. The raw data might not.

Behind the Numbers, Issue #1. Checking vendor numbers and building reports that lead to decisions.

BPO MetricsScott Grigsby · September 18, 2026


I don't trust a vendor's report until I run the math myself.

26 years in call centers taught me that. One customer taught me the hardest version of it.

That's what Behind the Numbers is for. Every week I take one number from a vendor report. I show where it can go wrong, how to check it yourself, and what a report that actually helps you decide looks like.

This week:

All three come back to the same thing.

The vendor's report is a story about the work. The raw data is the work.

When the two don't match, you're the one paying for the gap.


The customer who broke my dashboard

Our weekly dashboard was green. Average wait time was under target. Most calls were answered within two minutes.

Then a customer said this:

"I've called three times. Every time someone transfers me, I start waiting all over again."

I pulled her call history. She was right.

We answered her first call in 48 seconds. Then we sent her to a specialist queue, where she waited 19 minutes and hung up. Our report counted that call as a success.
Timeline of one call drawn to scale. A short blue bar for 48 seconds to answer, then a long red bar for 19 minutes waiting after a transfer, ending when she hung up. The report only counted the 48 seconds.

The specialist queue lived in a separate report. Neither report showed her whole call. And our average wait time only counted answered calls, so the people who gave up weren't in it.

Every team could hit its target while the customer still couldn't get help.

We changed the reporting to follow each call through every transfer. We put abandoned calls and repeat callers right next to answer speed. And we moved more staff into the specialist queue during its busiest hours.

The next dashboard had a lot more red. The next operations meeting was a lot more useful.


One check worth running this week

Put last month's vendor bill next to your agent login report. The hours should match.

It takes about an hour:

  1. Read the contract first. Find out what you pay for: scheduled time, logged-in time, or time spent helping customers.
  2. Pull billed hours from the invoice, by day if you can.
  3. Pull agent login hours from the phone system, by agent and by day. If the vendor owns the system, ask for the raw export, not a summary.
  4. Line them up day by day. Billed hours should not be higher than logged-in hours.
  5. Check ready time. How much of that logged-in time were agents actually ready to take calls?

Gaps usually come from training time billed as call time, full shifts billed when agents left early, or long stretches of not taking calls billed like work.

Some of that may be fine under your contract. The point is knowing which of it you're paying for before the next invoice lands.

Start with one week. It's faster, and it tells you if the rest is worth checking.


Two numbers to question

Service level. The report says 80% of calls answered in 30 seconds. The contract asks for the same. That looks like a pass. But check:

Here's what the half hour problem looks like on one example day. The day passes. Nine half hours don't.

Line chart of service level by half hour from 8am to 7:30pm. The day's service level is 82%, above the 80% target, but nine half hours from 12pm to 4pm fall below target, bottoming out at 63% at 2pm.
Example data, not a client result.

If your contract pays credits for missed service levels, any gap there is money.

Liquidation. A great liquidation rate can hide a weak collections vendor. Easy accounts make anyone look good. Before you trust the number, ask for:

If a vendor can't break the number down, that tells you something too.


What I put together this week

I moved my sample reports onto bpometrics.com so they're easy to find:


What's one number your vendor sends you that you've never checked?

Hit reply and tell me. It might be next week's issue.

If you want someone to run these checks on your own vendor data, start with the sample audit report at bpometrics.com/audit/sample.
