Non-Billable Work: What Fills the Other 30%

Your billable utilization is somewhere around 70%. You know this because you track it. But ask a different question (what fills the other 30%?) and most services firms go quiet.

That gap is not a mystery. It’s a mix of internal meetings, administrative tasks, status reporting, proposals, and operational coordination. Some of it is necessary. Some of it is friction that grew unchecked because nobody measured it. According to the SPI Research 2025 PS Maturity Benchmark, average billable utilization across professional services dropped to 68.9%, down from 73.2% in prior years. Firms are losing ground, and most don’t know where the time is going.

The firms that improve utilization don’t just push people to bill more hours. They break down non-billable time into categories, find the waste, and cut it.

What Non-Billable Time Actually Looks Like

Non-billable work falls into roughly five buckets. The first three are investments. The last two are friction.

Strategic investments:

Business development and proposals. Writing responses to RFPs, attending pitch meetings, building client relationships. This generates future revenue, so it belongs here.
Training and professional development. Certifications, internal knowledge sharing, onboarding new hires. Required for long-term capability.
Planned internal work. Strategy sessions, process improvement initiatives, tool evaluations. These keep the firm running.

Operational friction:

Administrative overhead. Filling out timesheets retroactively, chasing approvals, reconciling expense reports, entering the same data into multiple systems. None of this creates value for clients or the firm.
Internal coordination and reporting. Monday status meetings where everyone recites what they did last week. Project managers compiling reports from spreadsheets. Slack threads trying to figure out who’s available for next week’s engagement. This category grows fastest as firms scale, and it’s where the biggest opportunity sits.

In our experience working with mid-size services businesses, the friction categories (admin and coordination) typically consume 40% to 60% of all non-billable time. That’s 12% to 18% of a consultant’s total working week spent on tasks that could be reduced or automated.

Which Non-Billable Activities Can You Actually Shrink?

Not all non-billable time should shrink. Cutting training or business development to boost utilization is a short-term gain that creates a long-term problem. The goal is to protect the strategic categories while reducing the friction.

Four areas are worth examining first:

Time entry. If your team fills out timesheets on Friday afternoon from memory, you’re losing accuracy and burning time. We’ve covered why this matters. Systems that let people log time against active tasks in real time get rid of the end-of-week guessing game.
Status reporting. If a project manager spends two hours assembling a weekly status update by pulling data from email, spreadsheets, and a separate time-tracking tool, the problem isn’t the report. It’s the number of places the data lives. A single system that tracks project progress, time, and budget together makes the report a byproduct, not a project.
Resource coordination. “Who’s available next week?” shouldn’t require three Slack messages and a spreadsheet check. When staffing and project data live in one place, availability becomes a query, not a conversation. This connects directly to capacity planning.
Duplicate data entry. Client details entered into the CRM, then re-entered into the project system, then re-entered into the invoicing tool. Every re-entry is time wasted and an error introduced. Integrated systems enter it once.

The Math of Reclaiming Five Points

Consider a 25-person services firm billing at an average of $150 per hour, with utilization at 69%. That means each person bills roughly 27.6 hours per week.

If you reduce non-billable friction by just five percentage points (moving from 69% to 74% utilization), each person bills an additional two hours per week. Across 25 people and 48 working weeks, that’s 2,400 extra billable hours per year.

At $150 per hour, that’s $360,000 in additional revenue capacity. Nobody worked longer. Nobody skipped training. You just removed friction.

The SPI Research benchmark data shows that the gap between average firms (around 69% utilization) and top-performing firms (above 75%) isn’t explained by longer hours or fewer investments. Top firms simply have less operational friction. They spend less time on admin and more time on work that generates revenue or builds capability.

Frequently Asked Questions

What is non-billable time in professional services?

Non-billable time is any work a consultant or employee performs that cannot be charged to a client. It includes internal meetings, administrative tasks, business development, training, and operational coordination. Healthy firms aim for 20-30% non-billable time, but the composition matters more than the total.

How do you reduce non-billable time without cutting training?

Break non-billable time into categories: strategic investments (training, business development, process improvement) and operational friction (admin, status reporting, duplicate data entry). Protect the investments and compress the friction. Most firms find that 40-60% of their non-billable hours fall into the friction category.

What is a good billable utilization rate for a consulting firm?

Industry benchmarks suggest 70-80% as the healthy range for billable utilization. The SPI Research 2025 benchmark found the industry average at 68.9%, below the 75% threshold generally considered necessary for strong profitability. Pushing above 85% risks burnout and quality issues.

How Tier2 Keel Reduces the Friction

The admin overhead described above (duplicate data entry, scattered project data, manual reporting) exists because most services firms run their operations across disconnected tools. A CRM here, a project tracker there, a spreadsheet for resource planning, and yet another system for invoicing.

Tier2 Keel keeps the full lifecycle in one place, from lead capture through project delivery, time tracking, and invoicing. When project data, resource allocation, and financials live in the same system, status reports build themselves, time entry happens in context, and “who’s available next week?” has an answer without a Slack thread.

See how Keel works for services firms or book a walkthrough.

The 30% of your team’s week that isn’t billable won’t reach zero. But the portion spent on friction can. Start by measuring what fills the gap, not just how big it is.
