What Write-Offs Reveal About Your Accounting Firm

How High-Performance Firms Use Write-Offs to Improve Performance

Work in progress is one of the most important numbers in an accounting firm. Put simply, work in progress is work done, not yet invoiced.

Every time a team member records billable time, the firm creates work in progress. That work has value. It is an asset created through effort, skill, and time. When the firm invoices the client, that work in progress is reduced and exchanged for another asset, an invoice, which eventually becomes cash in the bank.

This is why WIP sits at the centre of strong Accounting Practice Management. It shows the journey from effort, to invoice, to cash. But the real value is not just in the total WIP number. The real value is in the movement behind it.

When a firm understands opening WIP, time added, disbursements, invoices, write-ups, and write-offs, it can see what is really happening inside the firm. It can see which jobs are profitable, which jobs are under pressure, and where the team is spending more time than expected.

Write-offs are often misunderstood. Some firms ignore them completely. Others use them as a stick to beat up team members. Neither approach helps.

High-performance firms use write-offs differently. They treat them as insight.

A write-off tells you that more work was completed than the firm recovered through invoicing. That might mean the job was underpriced. It might mean the scope changed. It might mean the team member needed more support or training. It might mean the client is difficult to work with, or that the job process needs to be improved.

The key is to look for patterns and outliers.

A single write-off may not tell you much. But if the same type of job is written off every month, there is something to investigate. If one client constantly produces poor recoverability, the pricing may need to change. If one task keeps taking longer than expected, the workflow or allocation process may need attention.

This is where good Accounting Practice Management becomes powerful. The data should help partners and managers have better conversations. Not emotional conversations. Not blame-based conversations. Better conversations based on what actually happened.

Recovered rates and average hourly rates are also useful because they cut through the noise. They show how much value the firm is recovering from the work being done. When these rates are low, the firm can investigate why. When they improve, the firm can see the impact of better pricing, better workflow, better allocation, and better team support.

The best firms do not hide from write-offs. They study them.

They use WIP and recoverability to understand where profit is leaking, where the team needs help, and where client pricing needs to change. They connect workflow, timesheets, capacity, invoicing, and reporting into one clear picture.

That is the real purpose of Accounting Practice Management. It is not just software for tracking jobs. It is the system that helps a firm turn effort into cash, improve performance, and make better decisions with data it can trust.
