Understanding Your Numbers: A Financial Guide for IT Agencies

Revenue Alone Doesn't Tell You If the Agency Is Healthy

A growing software consultancy can be busier than ever and still be bleeding margin. Three numbers reveal what total revenue hides: utilisation rate, project margin, and the split between recurring and project-based revenue.

Utilisation Rate: The Number Most Agencies Don't Track

Utilisation is the ratio of billable hours to total paid hours across your team. A team can be fully booked and still unprofitable if utilisation is low — time spent on internal tools, training, or unbillable client management eats into capacity that should be generating revenue, and it's invisible unless you're actually tracking it.

Project Margin: Quoted vs Actual

Comparing actual hours and costs spent on a project against what was quoted reveals margin erosion that's otherwise invisible until the project closes — by which point it's too late to fix. Fixed-price projects that run over scope are a particularly common source of this, since the agency absorbs the overrun rather than billing for it.

Recurring vs Project Revenue

Recurring revenue — retainers, managed services, support contracts — provides a predictable floor. Project revenue is lumpier and depends on a constant pipeline of new work. Knowing the split helps an agency understand how exposed it is to a quiet quarter.

Don't Overlook R&D Tax Incentives

If the agency is developing new software or technical solutions rather than just implementing off-the-shelf products, the R&D tax incentive is often relevant and commonly overlooked simply because agencies don't realise their development work qualifies.
