Time Tracking for Contractors and Services Teams

Overview

Time tracking for contractors, freelancers, and services teams is a different problem from time tracking for compliance. In a services business the timesheet is the source document for an invoice, which means an ambiguous entry is not an administrative annoyance — it is a line item somebody has to defend to a client, or write off. Getting the capture right is cheap. Reconstructing it three weeks later is not.

What follows is about what to capture and why, not about which product to buy. The fields come first; the tooling follows from them.

1. Capture the five fields that make an hour billable, and stop there.
2. Decide granularity once, deliberately — it is expensive to change later.
3. Capture at the time of work; recall is where margin quietly disappears.

The five fields that make an hour billable

Who. The person, and by extension their rate. If rates differ by role or by client, the rate needs to attach to the person-on-this-engagement rather than to the person globally, or you will be applying corrections at invoice time every month.

What it is against. The client, project, and — depending on how you bill — the phase, deliverable, or task. This is the field people cut when they simplify a timesheet, and it is the field that decides whether you can answer "what did this project actually cost".

How long. Duration, and whether you round. Rounding rules should be agreed with the client and applied by the system, not by whoever assembles the invoice.

Billable or not. A flag, set at entry rather than inferred later. Internal meetings, business development, and rework are all real hours that are not client hours; the distinction is only reliable if the person who did the work sets it while they remember.

A description a client would accept. The one that matters most and gets the least attention. "Development" is not a defensible line on an invoice; "implemented candidate export endpoint and unit tests" is. If your invoice narrative is assembled by a project manager paraphrasing terse entries, you are paying twice: once for the paraphrasing and again in the write-offs when a client queries a line nobody can substantiate.

Granularity: the decision everyone gets wrong once

Two failures, in opposite directions.

Too coarse. Time is booked against a client only. You can invoice, and you can tell whether the month was busy, but you cannot tell which engagement lost money or which phase overran. You find out at the end, when the remedy is a difficult conversation rather than a scope adjustment.

Too fine. A taxonomy with dozens of categories per project. People stop using it accurately — they pick the first plausible option and move on — and you now have precise-looking data that is quietly wrong, which is worse than coarse data that is obviously coarse.

The usable middle is the level at which you make decisions. If you price and negotiate by phase, track by phase. If you renegotiate scope by deliverable, track by deliverable. If you only ever compare projects against each other, project level is enough. Write down the question you want the data to answer, then track at exactly that level and no finer.

For contractors and freelancers billing a handful of clients, this usually resolves to client, project, billable flag, and a real description. That is four fields and it is genuinely sufficient.

1. Capture behaviour to look for:
   • Entry at the moment of work — a running timer or a desktop capture — rather than end-of-week recall.
   • Defaults that reduce typing: recent projects surfaced, last entry repeatable, sensible rounding.
   • A visible weekly total, so a missing day is noticed on Thursday rather than at invoicing.
2. Approval and correction:
   • A submit-and-approve step, so entries are reviewed before they reach an invoice rather than after a client queries one.
   • Corrections that are traceable, not silent overwrites.
   • A clear lock point after which a period cannot be edited.
3. What has to come out:
   • Export or integration into whatever raises the invoice, carrying the description through.
   • Utilisation and billable-ratio reporting per person and per project.
   • Budget-versus-actual against the estimate you quoted from.

Segment differences worth noting

Independent contractors and freelancers. The constraint is the invoice, and the whole system needs to survive being operated by one busy person. Capture as close to the work as possible, keep the description client-ready, and make sure the export feeds your invoicing without re-keying. Anything more elaborate will be abandoned by the second month.

Agencies and consultancies. The constraint is margin visibility across many concurrent engagements. Here the approval step and budget-versus-actual reporting matter more than the capture mechanics, because the failure mode is not a missing hour — it is a project that has been over budget for three weeks and nobody has looked.

Field and site-based work. The constraint is that the person is not at a desk. Capture has to work where the work happens, and location or job-site context is often part of the record. Be careful here: capturing location moves you from time tracking into territory with its own disclosure obligations.

That last point generalises. Timesheet data is personal data about an identified worker, and the more a tool captures beyond hours and task, the more it needs a documented purpose, disclosure, and a retention period. Where that line sits — and what to write down before switching capture on — is the subject of our piece on whether employee monitoring is legal and what to document. For billing purposes you usually need far less than a monitoring suite collects, which is a good position to be in.

Choosing timesheet software for a small services business

Start from the invoice and work backwards. Ask what your invoice needs to say, then check that the system can capture it and get it out. Most evaluations run the other way — feature list first — and end with a tool that captures beautifully and exports into a format your finance process cannot use.

Concretely: can it hold rates that vary by person and engagement? Can time be marked billable at entry? Does the description survive to the invoice intact? Is there an approval step before time becomes billable? Can you see utilisation and budget-versus-actual without exporting to a spreadsheet? And can the data leave — export or API — because it will need to.

In our suite Pace covers desktop time capture on Windows today, with a macOS client in progress, plus employee time entries and timesheets synced from the tracker, hour-utilisation reporting, and pay-period handling. Capture settings are administrator-controlled. If the work being tracked is planned somewhere, Stride PM is the planning side of the same platform, so hours land against the work rather than a free-text label. Delivery leaders looking at the whole path can start from the delivery teams view.

Where to go next

The step after capture is turning approved time into an invoice without a manual reconciliation in between — the gap where services businesses most often lose margin. We covered that path in from timesheet to invoice. If the problem you are actually trying to solve is visibility across projects and people rather than billing accuracy, how unified dashboards drive better operational decisions is the more relevant read.

Or tell us how your team records time today and what your invoices have to say, and we will walk through Pace against that rather than against a slide.
