The short answer

What KPIs should an accountancy practice track?

A short, actionable set: gross recurring fees and their growth, recurring percentage, top-10 client concentration, recovery rate, lockup (WIP + debtor days), utilisation, revenue per head and client retention. These describe income quality, cash health and productivity.

The numbers worth tracking are the ones that change what you do next. They are also the numbers a buyer will scrutinise if you ever sell. Each KPI in the table has a sensible target to aim at, and two of them, recovery rate and lockup, need a formula to calculate.

KPIWhat it tells youA sensible aim
GRF growthWhether your recurring base is growingPositive, ahead of inflation
Recurring %How predictable your income isThe higher the better; 80%+ is strong
Top-10 concentrationClient dependency riskNo single client dominating; watch above ~10%
Recovery rateBilled value vs value of work done90%+ on compliance
Lockup (WIP + debtor days)How long cash is tied up in the workflowLower is better; trend it down
UtilisationProductive time across the teamSustainable for the team (watch for burnout)
Revenue per headProductivity and pricingRising over time
Client retentionHow much of your fee base stays each year95%+ of fees retained

Targets are rules of thumb — set your own against your firm's mix and market.

The quality of your income

GRF growth, recurring percentage and client concentration together describe the quality of your income — how much there is, how predictable it is, and how safe. These are the numbers a buyer cares about most, because they determine the value of the firm. A firm whose fees are growing, highly recurring and well spread is healthier and more valuable than one whose fees are flat, project-heavy and concentrated.

How to calculate recovery rate and lockup

Recovery rate = fees billed ÷ the value of the time and work done, as a percentage. Consistently below ~90% on compliance means you're either under-pricing or over-servicing. Both can be fixed. Lockup = (WIP + debtors) ÷ annual fees × 365, giving the number of days' fees tied up before you're paid. High lockup means cash is held in work in progress and unpaid invoices until you bill and collect it, and it is often a warning sign of billing or delivery problems.

People and clients

Revenue per head is a simple measure of productivity and pricing. If it's flat while costs rise, pricing or productivity needs attention. Utilisation matters, but pushing it too high burns out good people, and then they leave. Client retention drives the rest of the numbers. A firm that keeps 95%+ of its fees each year grows on top of that base, while a firm that keeps losing clients has to win new work just to stay the same size.

Use each KPI to make a decision

Pick five or six of these KPIs, review them monthly, and use them to make decisions: re-price where recovery is weak, chase where lockup is high, diversify where concentration is rising, and invest where growth is stalling. If a number never leads to a decision, stop tracking it.

From numbers to decisions

Turning figures into decisions on pricing, capacity and growth is the job of a finance director, and it is what a good FD does for a firm owner. Better numbers also mean a more valuable firm if you ever sell, and they're the evidence base for pricing your advisory and lifting value.

What KPIs should an accountancy practice track?

A short, actionable set: gross recurring fees and their growth, recurring percentage, top-10 client concentration, recovery rate, lockup (WIP + debtor days), utilisation, revenue per head and client retention. These describe income quality, cash health and productivity.

How do I calculate lockup?

Lockup = (WIP + debtors) ÷ annual fees × 365. It's the number of days' fees tied up between doing the work and being paid. Lower is better; high lockup ties up cash and can signal billing or delivery problems.

What is a good recovery rate for a practice?

Broadly 90%+ on compliance work. Recovery rate is fees billed divided by the value of work done. Consistently below that points to under-pricing or over-servicing. Both can be fixed.

Why do KPIs matter when selling a practice?

Because the numbers that describe income quality — recurring percentage, concentration, retention, growth — are what a buyer scrutinises to set the multiple. Strong, well-tracked KPIs support a higher, more defensible valuation.
