Unit economics for managed services: contribution, cost to serve and break-even
For MSP service managers, finance staff and owners who need to know whether each managed service, and each customer agreement, actually makes money. Complete 'Pricing managed services: per user vs per device' first; it covers quoting a price and its gross margin. This course looks at the economics after the deal is signed: separating fixed and variable costs, contribution margin per seat, the cost to serve each customer using activity-based cost drivers, the number of seats needed to break even or hit a profit target, and what to do with agreements that don't cover their costs. The methods come from the OpenStax managerial accounting textbook; the rates, overhead pools and margin floor in the examples are fictional, so use your company's own cost model and contract terms.
