MSP Revenue Growth
The NRR Problem: Why MSPs Are Tracking the Wrong Revenue Metric Every Month
Dennis Kao
MRR tells you what you’re contracted for. NRR tells you whether your client relationships are actually growing.
Every MSP owner we talk to knows their MRR number. They can tell you what it was last month, what it is today, and what they need it to be by end of quarter. MRR is the heartbeat metric of the managed services business — visible, trackable, and directly tied to the contracts that keep the lights on.
The problem is not that MRR is wrong. The problem is that optimizing for MRR alone creates a blind spot large enough to drive significant revenue through without ever seeing it on a dashboard.
That blind spot has a name: Net Revenue Retention. And most MSPs in the $1M–$10M band are not measuring it, not reporting it, and therefore not managing the single metric that most clearly reflects the health and growth potential of their existing client relationships.
MRR measures what you’re billing. NRR measures how well your client relationships are actually performing as a revenue-generating asset. These are not the same thing — and the gap between them is where most MSP growth is hiding. |
The Difference Between MRR and NRR
MRR is a point-in-time measure: what are your clients contracted to pay you this month? It counts recurring contracts and excludes everything else. It is an excellent measure of contract stability and a poor measure of client relationship performance.
NRR measures something more complete: of the revenue your existing client base generated last year, how much did that same base generate this year — including contract growth, project revenue, expansion, and any contraction from churn or downgrades? A healthy NRR above 100% means your existing clients are collectively generating more revenue this year than last, without a single new logo. An NRR below 100% means the base is contracting, regardless of what MRR looks like on a given month.
What You’re Measuring | MRR Only | NRR (Full Picture) |
Includes contracted recurring revenue | ✔ Yes | ✔ Yes |
Includes project and expansion revenue | ✘ No | ✔ Yes |
Reflects client relationship growth | ✘ Partially | ✔ Fully |
Accounts for contraction and churn | ✘ Only at cancellation | ✔ Ongoing |
Used in M&A and valuation conversations | ✘ Secondary | ✔ Primary |
That last row matters more than most owners realize. When private equity firms, consolidators, and M&A advisors evaluate an MSP, MRR is a starting point. NRR is the evidence of whether that MRR is growing from within — which is the single clearest indicator of client relationship quality, service delivery strength, and future revenue predictability.
What a Healthy NRR Looks Like in the $1M–$10M Segment
Per Service Leadership Index benchmarks for the $1M–$10M MSP segment, healthy operators generate 20–50% of their annual MRR as project and NRR revenue from existing clients. That means an MSP with $500,000 in annual MRR should expect a further $100,000–$250,000 in total revenue from that same client base through project work, expansions, and upsells.
When that project and expansion revenue is flowing at the higher end of that range, NRR climbs well above 120% — meaning the existing client base is generating 20% more revenue year over year without any new client acquisition. At the lower end, NRR may barely clear 100%, meaning the base is flat despite stable MRR. Stable MRR with flat NRR is not a healthy business. It is a stagnant one.
An MSP with 100% MRR retention and 115% NRR is growing faster than one with 105% MRR retention and 100% NRR — and doing it from the client base they already have. |
The NRR Gap Is an Intelligence Gap
The reason most MSPs operate below their potential NRR is not that their clients don’t have project needs. It is that the signals pointing toward those needs are sitting in disconnected systems that nobody is correlating into a revenue opportunity before the quarter closes.
Aging assets in the RMM. Recurring ticket patterns in the PSA. Compliance deadlines in the documentation. Stalled strategic roadmap items from the last QBR. Each of these is an NRR signal. Together they represent the project and expansion revenue that would push NRR from 102% to 118%. Separately, sitting in four different systems, they represent missed revenue that never shows up anywhere on a monthly MRR report.
This is precisely where SKAIA’s revenue intelligence makes its most direct impact: correlating those signals across systems so that the expansion revenue available in every client relationship surfaces before the window closes, not after the client has taken the conversation elsewhere.
MRR will always be the heartbeat. But NRR is what tells you whether the patient is actually healthy. Start measuring it — and then make sure you have the intelligence layer that moves it in the right direction.
