A solicitor spends 18 minutes reviewing a client’s email trail before replying. An architect joins a coordination call that runs over by half an hour. An accountant fixes an error created by incomplete client records. None of that work looks dramatic on a timesheet, yet each item can determine whether a matter makes money. The question of which tasks count as billable is not administrative trivia. It is a margin decision.

Most firms lose revenue because their answer is vague, inconsistent or buried in the heads of senior staff. Employees then make judgement calls at 5pm, after a day of switching between clients, systems and meetings. Predictably, short tasks disappear, internal work gets mislabelled, and the invoice reflects what people remembered rather than the work the firm actually performed.

Which tasks count as billable?

A task is usually billable when it is performed for a specific client, is necessary to deliver the agreed service, and is permitted by the engagement terms or fee arrangement. That sounds simple. The difficulty is that professional work rarely arrives in neat, uninterrupted blocks.

A useful test is this: would a reasonable client see the activity as part of receiving the advice, output or service they are paying for? If the answer is yes, it should at least be allocated to that client, even if your commercial policy later decides not to charge for it.

That distinction matters. Client-related time and billable time are not always identical. A project manager may spend an hour resolving a problem caused by an internal handover failure. The hour belongs against the client project for profitability reporting, but the firm may decide not to invoice it. Hiding it as generic administration makes the project look healthier than it is.

For time-based firms, the strongest approach is to capture the work first and apply billing rules second. If people must decide whether a task is chargeable before they record it, valuable evidence vanishes.

Direct delivery work is billable by default

The clearest category is work that produces the service the client instructed you to provide. For example, this includes preparing accounts, drafting legal documents, developing a website feature, producing drawings, analysing data, building reports, reviewing contracts and managing a defined project deliverable.

It also includes the less visible activity needed to complete that output properly. Reading source documents, checking calculations, carrying out relevant research, preparing for a client meeting and quality-reviewing client work can all be chargeable where they are within scope and proportionate to the assignment.

The word “proportionate” does real work here. A complex tax issue may justify several hours of technical research. Charging a client for a junior employee’s first attempt at understanding a routine process probably will not. The task might be client-related, but the cost of training your team is usually yours.

Client communication often counts, even when it is brief

Emails, calls, video meetings and messages are among the most under-recorded forms of client work. They are also where many firms leak time. A two-minute reply might not be worth invoicing as a standalone entry, but ten such replies across a day can represent meaningful delivery effort.

Whether communication is charged depends on the engagement model. In a traditional hourly arrangement, substantive correspondence, calls and meetings are normally billable. Under a fixed-fee agreement, you may include them in the fee but still need to allocate the time to the client. That is how you learn whether the fixed price is protecting profit or quietly eroding it.

Not every message belongs on an invoice. Chasing a client for overdue payment, sending a standard diary invitation or answering a question you should have resolved earlier may be non-billable. But record the time against the right category. You cannot improve an unprofitable service if the hidden work remains invisible.

Meetings, planning and coordination depend on purpose

A meeting does not become non-billable because it happened on Teams rather than in a boardroom. If it moves a client matter forward, resolves a decision, gathers requirements or coordinates external parties, it is generally client work.

This includes internal project meetings where the discussion is specific to a client deliverable. A design team reviewing a client’s campaign is different from the agency’s Monday operations meeting. A civil engineering team planning a site issue is different from general resource planning. The client context, not the calendar label, decides where the time belongs.

Firms should be careful with recurring status calls. If a weekly call provides genuine oversight the client expects, charge it or build it into the agreed fee. If it exists because your own processes are unclear, it is an internal cost. Repeated non-billable coordination is not just an invoicing issue. It is a signal to fix delivery.

Tasks that need a clear firm policy

Some work sits in the grey area. These are the tasks that cause inconsistent timesheets, write-offs and avoidable client disputes unless the firm sets a rule before the invoice is raised.

The answer changes by sector and contract. A solicitor may have professional obligations that make detailed file administration unavoidable. An agency with a monthly retainer may include account management as part of its service. An accountant on a fixed annual fee may not charge separately for routine calls, but still needs to know how much time those calls consume.

Do not confuse client time with invoice time

This is where conventional time tracking fails. A start-stop timer asks people to choose a client before work begins, remember to switch when the work changes, then reconstruct the missing pieces later. That is a behavioural compliance system pretending to be financial control.

People forget. They get interrupted. They work across browser tabs, desktop applications, calls and documents. By the time they complete a weekly timesheet, the 12-minute review, 20-minute call and unplanned correction have collapsed into a guess.

A better operating model captures work activity as it happens, identifies the client context and gives people a sensible record to review. eppiq Timer applies Client Time Intelligence to recognise work patterns and allocate on-screen activity to the appropriate client without demanding constant timer discipline. The commercial benefit is not simply more recorded hours. It is more credible client-level data for invoices, utilisation, resourcing and profitability.

Automation does not remove judgement. A machine cannot decide whether you should charge for rework caused by your own error, or whether a fixed fee includes a meeting. What it removes is the false assumption that people can accurately recreate a fragmented working day from memory.

Build rules people can actually follow

A billable-time policy should be short enough for staff to use and specific enough for managers to apply consistently. Define the main billable categories, the common exclusions and the approval route for grey areas. Link the policy to engagement letters, rate cards and fixed-fee assumptions, rather than leaving it as a finance document nobody reads.

Give employees practical examples from your firm. “Client-specific research is chargeable if it is needed for the agreed work” is clearer when paired with examples from tax, architecture or project management. “Record all client-related time, even where it may later be written off” is even more valuable because it protects the data needed to see true margins.

Managers should review time at the point where it can still be corrected: during the week, before invoices are drafted, and after a project closes. Look for unusual patterns, such as a high volume of unallocated time, repeated write-offs, senior staff doing junior tasks, or a fixed-fee client consistently consuming more hours than planned. These are operational facts, not employee failures.

Charge fairly, measure honestly

Clients do not object to reasonable charges for work that advances their matter. They object to surprises, vague descriptions and paying for avoidable inefficiency. Clear scopes, transparent billing narratives and consistent judgement protect trust.

Your firm also needs the courage to measure work honestly when it cannot be charged. Every unbilled client task has a reason: it was included in the fee, written off for goodwill, caused by internal inefficiency, or excluded by contract. Those reasons reveal where pricing, process or client expectations need attention.

The practical rule is simple: allocate the time to the client whenever the work was done because of that client. Then decide, using agreed commercial rules, whether it appears on the invoice. Accurate capture gives you the choice. Memory-led timesheets take it away.
