## TL;DR

When invoice numbers do not add up, pull the usage event error export and filter by error type. Missing billable metric means the event_type was not wired up; missing price means the metric exists but has no rate for the event.

## Steps

1. When invoice numbers do not add up, pull the usage event error export and filter by error type. Missing billable metric means the event_type was not wired up; missing price means the metric exists but has no rate for the event. Treat received-after-finalization as a grace period problem, not a rating bug.

## When to use

You are seeing this: Missing billable metric means the event_type was not wired up; missing price means the metric exists but has no rate for the event. Use this skill when you run into "Metronome usage event errors: the seven error types to check when numbers look wrong".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
