Grow high-margin product share, sunset low-margin legacy products.
How do service businesses expand EBITDA without growing total revenue proportionally? By shifting what they sell toward higher-margin offerings within the existing client base — a move called product mix shift. Most businesses carry a revenue mix assembled opportunistically during a growth phase, with significant variation in margin by product or service line. The low-margin offerings often represent the majority of volume. Deliberately rebalancing that mix — without necessarily growing topline — is one of the cleaner paths to EBITDA improvement in a competitive market.
In physical infrastructure businesses — cash management, security services, facilities management — the mix shift often follows a technology layer being added to a commodity physical service. Loomis's SafePoint smart safe converts a cash pickup route into a data subscription. Brink's AMS and DRS products convert armored car visits into ATM managed service contracts. In both cases, the physical service remains, but the revenue mix shifts toward the recurring, data-enabled layer that commands a premium margin and creates switching costs the physical service alone never generated.
In professional services, the mix shift typically runs from project-based to managed services or from generalist to specialist. IT services companies have spent a decade trying to shift from labor-arbitrage application maintenance toward cloud migration, AI, and digital engineering — all of which carry higher bill rates and generate more referenceable work. The structural challenge is that the legacy mix funds the investment in the new mix, creating a sequencing constraint that most management teams underestimate.
The 13 published cases on this lever demonstrate that mix shift at scale requires three things: explicit portfolio decisions about which offerings to grow and which to harvest, pricing discipline to resist discounting the higher-margin offerings to win volume, and sales incentive structures that reward mix improvement, not just revenue growth.
