Write-Offs and Write-Downs
Also known as: billing adjustments, time write-offs
Definition
A write-down is a reduction in the billed value of recorded time before an invoice is sent - a partner or manager deciding the client should be charged less than the standard-rate value of the work performed. A write-off is a full cancellation of value, either of unbilled time before it is ever invoiced, or of an invoiced receivable the firm gives up trying to collect. Both are billing adjustments that directly reduce a firm's realization rate.
Where each one happens in the billing cycle
Write-downs happen at the pre-bill review stage: a manager or partner looks at the accumulated time on a matter, decides some of it should not be charged in full - because of scope disagreement, inefficiency, or a client-relationship judgment call - and reduces the invoice before it goes out. Write-offs can happen at that same stage (canceling time entirely rather than just discounting it) or later, after an invoice has already been sent, when the firm gives up trying to collect an aging receivable and formally cancels it as bad debt.
Why some write-downs are healthy and others are a symptom
Not every write-down is a problem - some reflect legitimate judgment calls about client relationships, fixed-fee arrangements, or genuinely inefficient work that should not be passed on. The signal worth watching is the pattern: if write-downs concentrate heavily around vague, generic, or memory-reconstructed time entries rather than around clear scope or pricing decisions, that points to a time-capture quality problem rather than a pricing one - reviewers are cutting what they cannot defend, not what they have decided not to charge for.
Why they are worth tracking separately from total realization
Lumping all adjustments into a single realization percentage hides which lever is actually driving the number. A firm with strong billing realization but weak collection realization has a collections process problem. A firm with weak billing realization has either a pricing and scoping problem or a time-capture quality problem upstream of billing. Separating write-downs (pre-bill) from write-offs (post-bill, uncollectible) makes it possible to diagnose - and fix - the right stage of the cycle.
Frequently Asked Questions
What is the difference between a write-down and a write-off?
A write-down reduces billed value before an invoice goes out - the client is charged less than standard-rate value, but something is still billed. A write-off cancels value entirely, either unbilled time that is never invoiced at all, or an already-invoiced receivable the firm gives up collecting.
Are write-downs always a sign of a problem?
No. Some write-downs reflect intentional pricing decisions - fixed-fee arrangements, client-relationship judgment calls, or work the firm agrees was inefficient. They become a concerning pattern specifically when they concentrate around vague, poorly documented time entries, which usually points to a time-capture problem rather than a deliberate pricing choice.
How can a firm reduce unnecessary write-downs?
The most direct lever is improving the specificity and timeliness of the underlying time entries, since vague or memory-reconstructed entries are the ones reviewers cut most often. Entries captured close to the actual work, with clear detail about what was done, tend to survive billing review intact far more often.
