Why Carrier Statements Don't Match — and How to Fix It

Variances are signal

Every variance between a carrier statement and your agency management system is information. Most agencies treat them as noise — write off the small ones, escalate the large ones — but the pattern of variances tells you whether your process is healthy or quietly bleeding.

The six recurring causes

• Endorsements processed mid-cycle. A carrier issued the endorsement but the AMS isn't aware of it yet, or vice versa. Statement shows the new premium; AMS shows the old.
• Split overrides applied differently. The carrier applied a 10% override for a year that the agency expected to apply at 12.5%. Often a contract-language issue rather than a software issue.
• Cancellation timing. Carrier processed a cancel effective on day 1; the agency didn't process until day 7. Six days of unearned premium drift.
• Audit premiums. Workers' comp and commercial lines deliver premium audits that retroactively change the earned premium for prior periods.
• Producer reassignments. Mid-year reassignments split one policy across two producers; the AMS attributes 100% to the new producer; the carrier statement shows the historical attribution.
• Currency / rounding. Less common, but real: carriers sometimes round at the line-item level, agencies at the policy level, and the totals diverge by a few cents per line.

A diagnostic process

When a variance shows up, work in this order:

1. Confirm the policy is in the same state in both systems (active vs cancelled vs endorsed).
2. Confirm the producer attribution matches.
3. Confirm the period covered matches (some carriers report on production date, others on commission-paid date).
4. Last, look at the math.

Most variances dissolve at step 1 or 2. The math is rarely wrong; what's wrong is two systems telling slightly different stories about the same policy.
