Timesheet: define the record before choosing an app
A timesheet records time spent on work during a specified period. It may support billing, project planning or employment administration, depending on the context. For freelance client work, agree on what is billable and how entries will be reviewed. A timesheet is not automatically an invoice or proof that every recorded hour should be charged. Its usefulness depends on clear categories and accurate, timely entries.
Use entries that explain the work
Include the date, project, task, duration and billable status where relevant. Add a concise description that a client can understand without exposing sensitive information. Avoid generic labels such as work when a clearer task is available. Record time close to the activity rather than reconstructing an entire month from memory. If a timer was left running accidentally, correct the entry and preserve an appropriate explanation.
Date | Project | Task | Hours | Billable? | Reviewer
[date] | [project] | Draft brief | 1.5 | Yes | [name]
[date] | [project] | Project meeting | 0.5 | Yes | [name]
[date] | Internal | Administration | 1.0 | No | [name]
Total hours: 3.0
Billable hours: 2.0
Illustrative rate: USD 60
Illustrative time charge: USD 120

Follow a simple illustrative example
Suppose a freelancer records 1.5 hours drafting a brief, 0.5 hours in a project meeting and 1 hour on internal administration. Total time is 3 hours. If the agreement makes only drafting and the meeting billable, billable time is 2 hours. At an illustrative $60 hourly rate, that supports $120 of time-based charges before any applicable adjustments. These figures demonstrate the distinction between total effort and billable work.
Keep approvals and changes clear
Agree on the submission period, reviewer and deadline for questions. Identify how corrections are requested and approved. A disputed entry should not be hidden by silently rewriting the record. Keep the final approved version accessible alongside the relevant scope or contract. Where billing is fixed-price, time records can still help assess capacity and project economics, even when the invoice is not calculated from hours.
Protect the information in the record
Do not include passwords, personal details or confidential material in task descriptions. Use an appropriate sharing method and limit access to the people who need it. Back up important records and follow relevant retention requirements. Employee timekeeping rules can differ from freelance client records, so seek appropriate guidance rather than assuming this example satisfies payroll or legal obligations in every setting.

Review patterns without overinterpreting them
Compare recorded time with the estimate and scope after a project. Look for recurring revision effort, unclear tasks or administration that was omitted from pricing assumptions. A single unusual week does not establish a lasting productivity trend. Improve the recording process and future estimates using documented observations. A good timesheet helps explain work and support fair review; it is not simply a timer running in the background.
Common questions
Is a timesheet always an invoice? No. A timesheet records work time; an invoice requests payment under the agreed terms. Some engagements use approved hours to calculate the invoice, while fixed-price work may use time records mainly for planning. Keep the documents’ purposes distinct.
Should I hide time spent on nonbillable work? No. Accurate internal records help you understand the total project effort, even when some time is not chargeable. Mark billable status clearly and follow the agreement. Nonbillable administration can inform future pricing without being silently added to a client’s bill.
