Billable hours are one of the most familiar performance measures in an accounting firm. They show how much time has been recorded to chargeable work, but they do not show whether the firm ultimately recovered the value of that work through its fees.
A staff member can meet a billable-hours target while the jobs they work on exceed scope, require rework or result in write-offs. A client can generate substantial activity and revenue while still delivering weaker commercial returns than expected.
Billable hours are therefore not misleading in themselves. They are simply incomplete when viewed without WIP, billing and recoverability.
What recoverability means in an accounting firm
Recoverability measures how effectively the value of work is converted into fees.
A common calculation is:
Recoverability percentage = fees billed ÷ WIP value cleared × 100
The exact definition depends on the firm’s practice-management system, rate structure and accounting policies. Some firms may treat write-ups, write-offs, disbursements, fixed-fee work or interim billings differently. The calculation should therefore be agreed and documented before results are compared across teams or periods.
Recoverability should also not be confused with cash collection. Once a fee has been invoiced, debtor reporting tracks whether and when the client pays it. Recoverability concerns the conversion of work or WIP into billed fees; collections concern the conversion of invoices into cash.
Why billable hours alone are not enough
Billable hours answer an important question: how much time was allocated to chargeable client work?
They do not answer:
whether the work remained within scope or budget;
whether the recorded time was billed in full;
how much WIP was written off or written up;
whether the fee adequately reflected the work performed;
whether the job required avoidable rework; or
whether the invoice was delayed in an approval queue.
Those factors become visible when productivity reporting is connected with WIP, billing and recovery.
For example, a team may record strong chargeable hours on a fixed-fee engagement. If the work consistently requires more time than the fee was designed to cover, the billable-hours result may look healthy while recoverability declines.
That does not automatically mean the staff members performed poorly. The cause may be inaccurate scoping, an unsuitable fee, inefficient workflow, insufficient training, poor-quality client records, delayed decisions or work being completed at the wrong level of seniority.
What recoverability by staff can reveal
Staff-level recoverability can help identify patterns that deserve investigation. It may show that work performed by a particular person is frequently written off, or that recovery differs materially across job types, managers or clients.
However, the figure needs context. An individual staff member does not usually control every factor affecting the final fee. Pricing, job allocation, supervision, scope changes and partner billing decisions may all influence the outcome.
For that reason, staff recoverability is most useful as a diagnostic measure rather than a simple scorecard. Managers should ask:
Is the result recurring or limited to one unusual job?
Is the staff member working on appropriately scoped engagements?
Was the original budget realistic?
Did the client provide complete information on time?
Was rework caused by a knowledge gap, process failure or changing instructions?
Who decided what amount would ultimately be billed?
Used this way, recoverability can support constructive coaching and process improvement. Used without context, it can assign responsibility to the wrong person.
There is also no universal target that suits every accounting firm. A suitable benchmark depends on service mix, pricing model, standard rates, role level and the firm’s commercial strategy. Firms should set and review their own thresholds rather than assuming that a single percentage, such as 90%, is appropriate everywhere.
What recoverability by client can reveal
Client-level recoverability helps identify relationships where the value of work is not consistently becoming billed revenue.
A longstanding client may generate substantial fees while also requiring unplanned support, repeated follow-up, additional review or work beyond the agreed scope. The relationship may still be commercially worthwhile, but revenue alone will not reveal the full picture.
Low client recoverability may prompt the firm to review:
whether the scope and engagement terms remain accurate;
whether recurring out-of-scope work is being documented and billed;
whether the fee reflects the complexity of the work;
whether the client’s records or responsiveness create additional effort;
whether jobs are being assigned to the right level of staff; and
whether workflow or review delays are creating unnecessary cost.
Recoverability reporting for accounting firms can connect the result to the clients, jobs, staff members, managers and partners contributing to it. This makes pricing and scope conversations easier to ground in evidence.
Recoverability is not the same as full client profitability. Profitability may also require salary costs, overhead allocation, software expenses, partner time and other direct or indirect costs. Recoverability is one important indicator of margin performance, not the complete profit-and-loss calculation for a client relationship.
Why WIP and recoverability must be viewed together
Recoverability only becomes clear when work is billed or otherwise cleared from WIP. Until then, a growing balance may contain work that will be billed in full, written down or delayed further.
That is why WIP reporting is an essential part of the analysis. Partners need to see where work is accumulating, how long it has been sitting and what happens when it is removed from WIP.
Looking at the measures together helps answer a more useful sequence of questions:
How much chargeable work was produced?
Where did the WIP accumulate?
How long did it remain unbilled?
What value was cleared when the job was invoiced?
How much was billed, written up or written off?
Which clients, jobs and operational decisions explain the result?
This is more informative than assessing billable hours or invoiced revenue in isolation.
Make recoverability part of regular management reporting
Manual recoverability analysis can be difficult when WIP, invoices and write-offs are held in separate exports or require repeated spreadsheet manipulation.
Practice Clarity connects timesheets, productivity, WIP, billings, recoverability and debtors through one reporting model designed for accounting firms. The reporting layer uses read-only access to supported practice-management data and provides role-based, drillable views through Microsoft Power BI.
The information is current as of the latest scheduled refresh, rather than being literally real-time or “always current.” Partners and managers can move from a headline result into the relevant client, job, staff member or transaction detail without rebuilding the analysis for each meeting.
The goal is not to replace professional judgement with a percentage. It is to make changes in recovery visible early enough for the firm to review scope, pricing, workflow, supervision or client behaviour while the outcome can still be influenced.
Frequently asked questions
What is recoverability in an accounting firm?
Recoverability measures how effectively the value of work or WIP cleared is converted into billed fees. The exact calculation should follow the firm’s agreed accounting and practice-management definitions.
Does recoverability include whether the client has paid?
Usually, no. Recoverability relates to billing and write-offs. Debtor and cash-collection reporting tracks whether the resulting invoice has been paid.
Why is recoverability useful alongside billable hours?
Billable hours show how much chargeable time was recorded. Recoverability helps show how much of the associated work value became billed revenue and where write-offs reduced the result.
What is a good recoverability percentage?
There is no universal target. The appropriate benchmark depends on the firm’s service mix, pricing model, rates, job types and commercial objectives. The firm should define a consistent calculation and set targets suited to its own operating model.
Is low staff recoverability always a performance problem?
No. It may reflect staff performance, but it can also result from pricing, scope, job allocation, supervision, client behaviour or a partner’s billing decision. The underlying job and transaction detail should be reviewed before conclusions are drawn.
