How a Law Firm's Evergreen Retainer Rule Kept Breaking Its Trust Reconciliation

How a Law Firm's Evergreen Retainer Rule Kept Breaking Its Trust Reconciliation

This is an illustrative anonymized composite, not a specific client engagement. It is built from patterns that recur across small law firms. The figures are illustrative, and no outcome described here is typical or guaranteed.

The firm had done the hard thing already. Eleven attorneys, an evergreen retainer policy on every hourly matter, and a managing partner who took trust accounting seriously enough to have read the rules.

And the three way reconciliation had not tied cleanly in fourteen months.

That is the shape of the problem with evergreen retainer trust accounting. It does not break in firms that are careless about client money. It breaks in firms that added a sensible billing policy and never told the books about it.

The Setup: How Evergreen Retainer Trust Accounting Is Supposed to Work

An evergreen retainer, sometimes called a replenishing retainer, works like a floor. The client funds the trust account to an agreed amount. As the firm earns fees and transfers them out, the balance drops. When it falls below the floor, the client is asked to top it back up.

It is a good policy. It is why the firm got paid on time while peers chased receivables.

It also creates something that a flat one-time retainer does not: a recurring event, driven by a threshold, that generates a request for money which is not a bill for services. And a request for money that is not a bill for services is exactly the thing accounting software gets wrong.

What Broke

Two failures, and only one of them was visible.

The visible one. Replenishment requests were being generated as invoices in the billing system. Invoices, in that system's default configuration, post to accounts receivable and flow to revenue when paid. So when a client wired $8,000 to top up a retainer, the books recorded $8,000 of revenue for work that had not been done, while the money itself sat in the trust account where it belonged.

The result was a general ledger that showed the trust liability and the operating revenue disagreeing by a growing amount, and a three way reconciliation between the bank, the client ledger, and the trust liability that never came out even. The bookkeeper had been posting a monthly adjusting entry to force it. Fourteen of those adjusting entries had accumulated.

Nothing had been stolen. No client money was missing. The bank balance was fine. But the firm could not demonstrate that with a clean reconciliation, which in a compliance review is a different sentence than "nothing is wrong."

The quiet one. The floor was not being enforced. The policy said replenish at $2,500. Nothing in the system watched for it. Enforcement happened when a paralegal noticed, which meant it happened on the matters with attentive paralegals.

Of 94 open matters, 31 were below the stated floor. Nine had trust balances under $250 against active work. Two were at zero and being worked anyway, which means the firm was providing services with no funds on hand and no one had decided to do that.

The Fix, in Order

Order mattered here, because fixing the enforcement problem before the recording problem would have generated a wave of correctly requested money posting incorrectly.

First, separate the money request from the invoice. Replenishment requests were moved out of the invoicing workflow and into a request document that does not touch revenue or accounts receivable. Client funds received go to the trust liability and the trust bank account, and nowhere else, until they are earned.

Second, rebuild the per-matter trust ledger. Every matter got its own trust ledger that reconciles to two things: the trust bank account in aggregate, and the client's own record of what they funded. Three way reconciliation is only possible when the third leg actually exists at the matter level rather than as a total.

Third, make the trigger produce a task. The floor was encoded as a rule that generates a work item when a matter's trust balance falls below it. A threshold that lives only in a policy document is a hope. A threshold that creates something in somebody's queue is a control.

Fourth, write down the transfer rule. When fees are earned, funds move from trust to operating. The firm wrote down when that happens, who authorizes it, and what documentation it requires. Previously this was three different practices depending on which partner was involved.

Fifth, clear the adjusting entries. The fourteen forced entries were unwound and the underlying transactions reclassified. This was the slowest part and produced no visible benefit, which is why it is the part firms skip.

What Changed

	Before	After
Months since a clean three way reconciliation	14	Current month ties
Forced adjusting entries outstanding	14	0
Open matters below the stated trust floor	31 of 94	4 of 94
Matters with an active file and a zero trust balance	2	0
Revenue recognized on unearned retainer funds	Present, growing	None
Time to close the month	3 days	5 days

The last row is the honest one. The close got slower, permanently, because the controls added steps. The firm traded two days a month for a reconciliation it can hand to anyone.

The four matters still below the floor are below it on purpose, with a documented partner decision on each. That is the difference between an exception and a leak.

What It Cost

The cleanup took about six weeks of part-time work and a real bill. The reclassification of prior periods required the CPA to look at whether anything flowed through to filed returns, which was additional fees on top.

The billing partner disliked the new process and said so. Requesting a replenishment now requires a step that used to be a click, and the task queue makes visible how often matters run thin, which is uncomfortable information.

And none of this is a guarantee of anything. A firm with clean books can still have a bad outcome in a review, and a firm with messy books often never has one. What changed is that the firm can now demonstrate its position rather than assert it.

Why Evergreen Retainer Trust Accounting Is a Bookkeeping Specialty

General bookkeepers are good at general bookkeeping. Trust accounting is a different discipline with different failure modes, and the software defaults actively work against it.

Legal Ease Bookkeeping is a Fort Worth, Texas firm founded in 2016, with 12 employees, serving law firms nationwide. Law firm bookkeeping is the whole practice. It lists a minimum of $500,000 in revenue for the firms it works with.

The relevant thing about a specialist here is not enthusiasm, it is that the evergreen retainer pattern above is a known pattern to someone who has seen fifty firms and a novel discovery to someone who has seen one.

Legal Ease Bookkeeping has 9 verified client reviews on Sam's List as of 2026-09-15. Each review is submitted by an individual who identifies as a client of the firm and rates it on communication, subject-matter knowledge, and overall satisfaction. Reviews reflect those individual experiences and do not represent an endorsement by Sam's List. Legal Ease Bookkeeping is a paying Sam's List member, and payment does not buy, influence, or remove reviews. Ratings and rankings are not indicative of future performance or results.

The limitations are real. A specialist costs more than a general bookkeeper, the $500,000 minimum excludes smaller practices, and no bookkeeper can substitute for your own reading of your state bar's rules. Trust accounting requirements are set state by state and they differ in ways that matter, including what a reconciliation must contain and how often. Your obligations come from your bar, not from your bookkeeper.

Frequently Asked Questions

What is a three way reconciliation in law firm trust accounting?

It is an agreement among three figures: the trust bank account balance, the total of all individual client trust ledgers, and the trust liability on the firm's books. All three should equal each other at a point in time. Most state bars require it periodically, and the individual client ledgers are the leg most often missing.

Is an evergreen retainer client money or firm money?

Funds held in trust generally remain the client's property until the firm earns them, which is why they sit in the trust account rather than the operating account. Recording a replenishment as revenue when received treats unearned client money as firm income. The specific rules on when fees are considered earned vary by state, so confirm with your bar.

Can accounting software handle trust accounting on its own?

Not on default settings, which is the source of most of these problems. General accounting software will happily post a retainer request to revenue because that is what it does with invoices. Either a legal-specific system or a deliberately configured setup plus a documented process is required, and the process matters more than the software.

How often should we run the reconciliation?

Many state bars require it at least monthly, and some are more specific about timing and documentation. Monthly is a reasonable floor regardless of the minimum, because the cost of finding a problem grows with how long it sits. Check your own state's rule rather than a national norm.

If your last clean three way reconciliation is more than a quarter old, that is the thing to schedule this week. You can browse bookkeepers on Sam's List if the cleanup is bigger than your current help.
