Why doesn't my commission income match my P&L?
Because the two records answer different questions. Your agency management system describes the book of business you have in force right now, while your general ledger reports the money that actually posted during a period. Timing, direct-bill statements, contingent income, excluded lines, and unmatched deposits all sit between them. A gap is normal — an unexplained gap is the problem.
Are the two numbers even supposed to match?
No, and expecting them to is the most common way this review goes wrong.
An AMS commission run-rate is a rate. It takes the policies in force on a given day, applies the commission you expect to earn on each, and annualizes. It describes a standing position.
Your general ledger reports a flow. It records what was received and posted between two dates. Comparing an annualized position to a month of posted cash is comparing a speedometer reading to the miles you drove last Tuesday. Both are correct; they are not the same measurement.
So the useful question is never "why don't these agree?" It is "which of the known differences explain this gap, and is anything left over?"
What are the five structural reasons for the gap?
In most independent agencies, nearly all of the difference comes from the same five places.
- Timing. A policy goes in force the day it is written. The commission on it may post weeks or months later, and renewals cluster unevenly across the year. The book moves before the ledger does.
- Direct bill. When the carrier bills the client directly, you learn what you earned from a commission statement that arrives after the fact — often without policy-level detail. Your AMS may show the policy while the ledger is still waiting on the statement.
- Contingent and profit-sharing income. This is real revenue in the general ledger with no policy behind it in the book. It is earned on aggregate performance, frequently paid annually, and it can be a meaningful share of profit. Nothing in the AMS predicts it.
- Excluded lines. Fee income, brokered placements, and business written through another agency's paper may post to the ledger without ever appearing in your in-force book — or the reverse.
- Unallocated remainder. Carrier payments that could not be matched to a specific policy. Small agencies often have very little of this. If it is growing, that is worth knowing.
How much of a gap is normal?
There is no universal number, because it depends on how much of your book is direct bill and how much of your revenue is contingent. An agency with heavy direct-bill personal lines will see a much wider and more volatile gap than a commercial agency on agency bill.
What matters is not the size of the gap but whether it is accounted for. A reconciliation that names each difference and lands on a small remainder is healthy. A reconciliation that lands on the right answer only after someone quietly plugs the difference is not — and the plug tends to grow.
Which part of the gap actually signals a problem?
The unallocated remainder, and any difference that changes shape month to month without explanation.
A stable, explainable gap is just how the two systems work. A remainder that grows, or a timing difference that stops behaving like timing, usually points at something specific: a carrier statement that stopped arriving, a commission rate set up wrong in the AMS, a book transfer that never got recorded, or business being written outside the system entirely.
This is also why a single reconciled total is worse than useless. Once the two records are forced into one number, the very thing that would have warned you disappears.
What does a good monthly reconciliation actually look like?
Four things, in order. Start from the AMS commission run-rate for the period. Name each structural adjustment and its source. Show whatever remainder is left unallocated rather than absorbing it. Then compare the result to booked commission income in the ledger.
The output is not a single reconciled figure. It is a short list of named differences that an owner can read in a minute and challenge in two.
What this looks like in practice
What to do with this in your own review
Pull your AMS commission run-rate and your booked commission income for the same period, then try to name every difference between them. Whatever you cannot name is the number worth investigating — and it is usually the only one that needed your attention.
