Most services businesses underestimate how much revenue is sitting in their existing client base. Single-service clients cost nearly as much to manage as multi-service ones -- and they're far easier to lose. The operators who solved this didn't hire more salespeople. They changed what they were selling and who was responsible for selling it.
Before ABM Industries launched its ELEVATE strategy in 2021, approximately 20% of its revenue came from clients using two or more services. The other 80% was single-service accounts: one contract, one buyer, one easy cancellation decision. Industry data ABM cited at its Investor Day showed that integrated facility management contracts carried 15-20% margin premiums over single-service deals, and clients on bundled contracts retained at rates above 95% versus roughly 85% for single-service accounts. ABM had the service lines to sell those contracts. Its organizational structure made it nearly impossible.
The company operated five siloed segments, each with its own P&L, sales team, and client relationships. A business development manager in janitorial had no commercial incentive to introduce the HVAC team -- and every reason not to, since the referral didn't affect his numbers. The problem wasn't market demand. Large enterprise clients were actively consolidating vendors and asking for single-point accountability across facility services. The problem was internal.
ABM's solution was structural. Rather than adding cross-sell incentives on top of the existing organization, the company dissolved the product-line P&Ls and reorganized around industry verticals. Account leaders became responsible for the full portfolio. The economics followed: average IFS contract value reached approximately $4.2 million annually, roughly five times the $800K average for single-service accounts. EBITDA margin expanded from 5.2% to 6.8% -- 160 basis points -- over four years as multi-service client revenue grew from an estimated 20% to 30% of total revenue. -> ABM ELEVATE
ISS faced the same structural barrier: country-level P&Ls that made cross-service coordination nearly impossible across 70+ countries. The OneISS strategy dissolved the country structure in favor of global key account management with integrated service delivery -- bringing cleaning, security, catering, and technical services under unified commercial accountability. Key account contract retention reached 95% under the new model. -> ISS OneISS
Compass Group and Sodexo both ran the bundling logic in food services: package catering with cleaning, front-of-house management, and workplace experience under a single contract. Compass grew revenue 25% above pre-COVID levels while improving margin 60 basis points. Sodexo's IFM wins -- a £10 million five-year contract with a global bank covering catering, cleaning, technical services, and gym management -- represent a revenue structure that a standalone caterer can't match. -> Compass bundling · -> Sodexo IFM
The organizational barrier is the consistent theme. Every company that solved this made the same structural move: unified account ownership with commercial accountability for the full portfolio. Overlay specialists and cross-referral incentive schemes are tried first and generally fail. Split P&Ls create internal competition -- a salesperson measured on their division's margin will not generate leads for a sister division unless the accounting forces it.
Multi-service bundling also changes the competitive landscape. A client managing five separate vendor relationships can benchmark each one individually at renewal. A client on a single integrated contract is evaluating total value, total accountability, and the cost of transitioning five services simultaneously. The switching cost compounds with every service added.
The risk is delivery. A cross-sell that brings services you can't execute well damages the core relationship faster than no cross-sell at all. ABM's approach -- a white-space analysis of each top-500 account before any active pursuit -- was about sequencing the cross-sell to services the company could credibly deliver, not just the ones the client might buy.
Start with wallet share, not headcount. What percentage of your top 50 accounts use more than one of your service lines? If the answer is less than 30%, the revenue opportunity in the existing base is likely larger than anything in new business pipeline.
The organizational question follows: does your current structure make it easy or hard for an account manager to bring in a second service line? If the answer involves separate P&Ls, separate sales teams, or no shared accountability for client retention, the cross-sell problem is structural and won't be solved with an incentive scheme.
Read these alongside the playbook — look for what each company had in common, and where their approaches diverged.
