Understanding Your Numbers: A Guide for IT Agencies

Revenue Looking Healthy Doesn't Mean the Business Is Healthy

It's easy for an IT agency or managed services provider to look at total monthly revenue and feel reassured. But three underlying numbers, recurring versus project revenue, technician utilisation, and per-client margin, tell a very different story about whether the business is actually sustainable.

Recurring Revenue vs Project Revenue

Managed services revenue under a recurring contract is predictable and far easier to plan staffing and cash flow around. Project revenue, one-off installs, migrations, builds, is lumpy by nature. An agency that doesn't separately track the split can mistake a good project month for sustainable growth, then struggle when the next quarter has no projects lined up.

Technician Utilisation Rate

Utilisation is billable hours divided by total available hours. It's one of the most revealing numbers in the business and one of the easiest to lose track of if time isn't logged accurately against jobs and clients. Low utilisation often hides in plain sight, everyone looks busy, but not all of that time is billable.

Margin Per Client

Not every client is equally profitable. Fixed-fee managed services contracts that were under-quoted on support time, or clients running outdated infrastructure that demands more hours than budgeted, can quietly erode margin even while total revenue looks fine. Tracking margin per client, not just total revenue, exposes which contracts need repricing.

Where Bookkeeping Fits In

None of these numbers are visible without accurate time tracking flowing into Xero, and revenue coded by contract type rather than lumped into one general income account. This is structural bookkeeping work, not just end-of-quarter reporting.
