Realization Rates: Billing, Write-Downs and Collections in a CPA Firm

Realization measures how much of the value of the work done becomes cash. It is the link between timekeeping and revenue, and it shows what an engagement loses at three points: when time is recorded, when it is billed and when it is collected. A firm that tracks only total revenue misses where the leakage happens. This article defines the measures, shows how to compute them and explains how to act on them. The firm's own history is the best yardstick. The glossary has the related terms in realization and utilization.

The three measures

Start with standard value: hours recorded multiplied by the firm's standard rate for each person. Then:

• Billing realization is amount billed divided by standard value of time charged to the engagement. It shows write-downs at the billing stage. Before invoicing, a partner reduces the bill because the engagement overran, the client disputed the scope or the work was inefficient.
• Collection realization is cash collected divided by amount billed. It shows what was lost after invoicing, through write-offs, discounts and uncollectible balances.
• Overall realization is cash collected divided by standard value of time. It combines the two and is the best summary of what the firm earned from the work.

Compute each by client, by engagement, by partner, by service line and by period. The pattern across those cuts tells more than the firm-wide figure.

How the three measures connect

Let S be the standard value of the time recorded on an engagement, B the amount billed and C the cash collected. Billing realization is B divided by S. Collection realization is C divided by B. Overall realization is C divided by S, which equals the product of the first two. The identity is useful in review: when overall realization falls, dividing it into its two factors shows whether the loss happened before the invoice or after it. Each firm computes the measures from its own records and compares them with its own prior periods.

Where the leakage occurs

At timekeeping

• Time not recorded, or recorded late and under-reported.
• Time recorded to the wrong engagement.
• Non-chargeable time, such as training and administration, mixed with billable time.

At billing

• Fixed fees set below the time the work needs. See engagement economics.
• Unbilled work in progress that waits months to be invoiced.
• Write-downs for rework or inexperienced staff.
• Out-of-scope work absorbed without a change order. See CPA firm pricing models.

At collection

• Invoices without clear terms, or sent late.
• Clients who treat the firm as the last creditor to be paid.
• Disputes about quality, scope or fee that were never raised earlier.

Reading the numbers

• By client. A client with low overall realization is either underpriced or hard to work for. Both are reasons to change terms.
• By service line. Low realization in one line can mean the pricing model for that line is wrong.
• By partner. Partners differ in scoping and billing habits. The comparison is a coaching tool.
• By staff level. If realization drops when junior staff do the work, the budget needs more review time or the staff need training. See staff training plans.
• Over time. A decline for a client across years shows scope creep.

Compare each against the firm's own prior periods and its targets.

Work in progress and receivables

Realization depends on how quickly time becomes cash. Track:

• Unbilled work in progress by engagement and age. Old WIP rarely realizes at full value.
• Accounts receivable aging. Review the aging each month by partner, and assign each past-due invoice an owner and an action. The firm's own receivables get the same discipline as a client's. See accounts receivable aging and allowance.
• Retainers and progress billing. Bill in stages for long engagements so that WIP does not pile up.

Billing practices that raise realization

1. Bill on a fixed schedule, not whenever a partner finds time.
2. Send invoices with a short summary of work done and a clear due date.
3. Collect a retainer or deposit for new or higher-risk clients.
4. Raise scope problems at the time they appear and document the discussion.
5. Pause work for clients with significantly overdue balances, according to the engagement letter. Remember that Circular 230 section 10.28 requires a practitioner to promptly return, on request, the client records needed for federal tax compliance, and a fee dispute generally does not relieve that duty.
6. Review write-downs and write-offs monthly and record the reason.

Governance

Set responsibilities: who approves write-downs, who follows up on collections, and who reports the metrics. Show the metrics to the partners monthly in one page: billing, collection and overall realization by service line, WIP age and receivable age. Tie partner reviews to the metrics only if the metrics are accurate and the definitions are agreed in advance, or the measure will encourage under-recording of time.

A caution on the measure

Realization can look high because the standard rates are low or because time is under-recorded. Keep the standard rates current and keep timekeeping honest. Quality of the work and independence requirements must not be compromised to improve a metric. See engagement quality review.

FAQ

Is a realization rate of 100 percent the target?

Not necessarily. Some work is deliberately priced below standard, and the firm should know which and why.

Where do write-offs belong in the metrics?

In the stage where they occur: pre-billing write-downs in billing realization, post-billing write-offs in collection realization.

Do fixed fees break the measure?

No. The standard value of time is still recorded and compared with the fixed fee billed.
