Best Timesheet Software for Consultants (2026)

The right timesheet software for consultants does two things at once: it captures every billable minute so nothing falls off an invoice, and it produces documented time records that satisfy federal labor law. Those two goals are inseparable, and the tool you choose determines how painlessly you hit both. This guide walks HR owners and operations leads through what to look for, what the law requires, and how to pick a tool your team will actually use.

What Should Timesheet Software for Consultants Actually Do?

Generic time clocks track when someone punched in and out. A consulting firm needs to link every hour to a client or project so you know what to bill, what to write off, and where capacity is going. Under 29 CFR § 516.2, employers must record hours worked each workday and total hours worked each workweek for all covered employees. Good consultant time tracking software meets that floor and goes further.

Billable vs. Non-Billable Tagging

Time entries should carry a billable or non-billable flag. Billable time goes on client invoices. Non-billable time, covering internal meetings, business development, training, and admin, stays on your cost side. Software that applies this split at entry gives you a real utilization rate without weekly spreadsheet work. In our experience, consulting teams are consistently surprised by how much capacity goes to non-billable tasks once they start measuring it.

Project and Client Hierarchy

Entries organized as client, then project, then task give you invoice-ready summaries without extra cleanup. When a consultant logs four hours to Client A, Phase 2, Discovery, you can compare estimated to actual hours before the engagement closes. That comparison is how well-run firms catch scope creep before it turns into a write-off conversation with the client.

Mobile Access and Same-Day Logging

Consultants work from client sites, home offices, and airports. A purpose-built employee time tracking system with a mobile app removes the friction that causes skipped entries. The practical rule: log time at transition, not at day-end. Every time a consultant switches from one client to another, a quick retag takes 10 seconds and eliminates Friday guesswork entirely.

Do Federal Recordkeeping Requirements Apply to Your Consulting Firm?

Yes, and the answer surprises many firm owners. Under 29 CFR § 516.2, every employer covered by the FLSA must maintain records of hours worked each workday and total hours each workweek for non-exempt employees. Salaried status does not automatically mean exempt. Many consultants classified as salaried actually meet the criteria for non-exempt status, which triggers the full tracking and recordkeeping obligation.

Here is the math on missed overtime: if a non-exempt consultant earns $40 per hour and works two unreported overtime hours in a week, the unpaid premium is $40 (0.5 x $40 x 2). That is one employee, one week. Across a 10-person team over a quarter, potential exposure can exceed $5,000 before any DOL penalties apply. Accurate software closes that gap at the source rather than in a settlement.

Those records must be retained. 29 CFR § 516.5 sets the minimum retention period for payroll records, including time records, at three years. If a Wage and Hour Division audit surfaces and records are missing, courts have allowed employee testimony about hours worked to stand in their place. Timestamped, cloud-stored records are the most defensible posture your firm can take.

Comparing Timesheet Software Options for Consulting Firms

The global time tracking software market is forecast to grow at a CAGR of 20.40% through 2028 (FinancesOnline), which means new tools appear every quarter. The table below covers established options as of mid-2026. Pricing changes frequently, so confirm current plans on each vendor's site before purchasing.

Kloqk	Yes, unlimited employees	Time entries by employee; export for billing review	Consulting firms with W-2 staff needing FLSA compliance plus hour capture
Clockify	Yes, unlimited users	Project and client tagging, billable rate by user	Freelancers and small teams tracking hours per client
Toggl Track	Yes, up to 5 users	Project and client hierarchy, billable rate settings	Small consulting teams wanting a quick-start browser timer
Harvest	Limited (1 user, 2 projects)	Invoicing integration, expense tracking	Firms that want billable hours to flow directly into client invoices
QuickBooks Time	No	Yes, with QuickBooks payroll and accounting integration	Firms already running payroll through QuickBooks

Pricing and feature availability change. Verify current plans on each vendor's site before purchasing.

According to FinancesOnline, only 17% of people actively track their time. For a consulting firm, that gap means most of your team is estimating invoice hours rather than reporting actual data. Estimates drift: they tend to undercount internal overhead and overcount focused client work, which compresses margins quarter by quarter without anyone noticing until a profitability review.

How to Build a Billable Hour Tracking Habit That Sticks

Software solves the data problem. Process solves the adoption problem. Most tracking failures happen because teams log hours retroactively, reconstructing a week from memory on Friday afternoon. A few small changes close that gap and keep it closed.

1. Log at transition, not at day-end. Train consultants to start a new time entry every time they switch tasks or clients. It takes 10 seconds and eliminates the Friday reconstruction problem entirely.
2. Use the mobile app. If someone is at a client site or working from home, they need to punch in from their phone. A free time clock with mobile access removes the friction that causes skipped entries on offsite days.
3. Set a same-day cutoff. A firm rule that all time entries are submitted by end of business keeps logs accurate and gives managers something to audit each morning rather than at month-end.
4. Review utilization weekly. A weekly report showing billable versus non-billable hours per consultant lets you course-correct before an entire month of capacity disappears into untracked overhead.
5. Verify totals before invoicing. Use a time card calculator to cross-check hours against your system's export before submitting client invoices. A one-hour discrepancy on a $250-per-hour engagement is a $250 error that erodes client trust even when corrected after the fact.

When every hour is logged at the moment it happens, your invoices are defensible, your utilization data reflects reality, and your payroll records can withstand a DOL audit without scrambling for backup documentation.

Frequently Asked Questions

Is timesheet software legally required for consulting firms?

If your consulting firm employs W-2 workers who are non-exempt, federal law requires tracking and recording their hours under the FLSA. 29 CFR § 516.2 requires records of hours worked each workday and each workweek, retained for at least three years under 29 CFR § 516.5. Timesheet software is not mandated by name, but it is the most defensible way to meet that obligation.

What is the difference between billable and non-billable hours in timesheet software?

Billable hours are time spent on client-facing work you can charge for: project calls, deliverable creation, and client-specific research. Non-billable covers internal meetings, business development, and admin work. Good timesheet software flags each entry so reports separate chargeable time from overhead, giving you an accurate picture of your effective billing rate per engagement.

Can a small consulting firm use free timesheet software?

Yes. Free tiers from tools like Clockify or Kloqk cover the core needs for most small consulting firms: clocking in and out, assigning time to projects, and exporting reports. The limits on free plans, usually seat counts or advanced reporting features, matter more as you grow past 10 people. For firms with W-2 employees, Kloqk's free time clock handles flexible schedules with no per-seat charge, which represents real savings over per-user billing tools.

How do I track time across multiple clients or projects?

Most dedicated timesheet tools let you create a hierarchy: client, then project, then task. Employees assign each time entry to the right level when clocking in or logging hours. The key discipline is logging same-day rather than reconstructing at week-end. Export timesheet data by employee and date range, then apply client tagging in a spreadsheet or your invoicing tool of choice.

What records do I need to keep for IRS and labor compliance?

For FLSA compliance, you must keep payroll records, including hours per day and per week, for at least three years per 29 CFR § 516.5. For IRS purposes, detailed timesheets substantiate labor cost deductions. Some states require longer retention periods, so check your state's Department of Labor rules. Cloud-based timesheet software makes the three-year minimum retention essentially automatic and exportable on demand.
