VMS vs MSP — which one are you actually buying?

The supply base, not the recruiting. A managed service provider decides which suppliers sit on the panel, how work reaches them, whether their submissions meet the agreed standard, whether their rates match the agreed terms and whether their workers hold current documents. Hiring managers still choose who they want and suppliers still find the people. That distinction causes most of the friction when a programme is introduced: suppliers who expected a client discover an administrator of somebody else's rules, and hiring managers who expected speed sometimes find the opposite for the first few months, because a programme replaces informal relationships with a process. Both reactions are predictable and both are worth setting expectations about before go-live.

Under a neutral arrangement the managing organisation administers the panel but places nobody itself, so it has no stake in which supplier wins. Suppliers generally prefer this, because the referee is not also a player. Under a master arrangement the managing organisation gets first opportunity on roles and passes on what it cannot cover to subcontracted suppliers. Each carries a real trade-off. Neutral removes the conflict of interest and adds a layer that fills nothing. Master can be faster and simpler for the buyer to manage, and concentrates dependency on one organisation while asking it to judge competitors for work it also wants. Whichever you choose, settle explicitly what happens to a role the primary route cannot fill, and how quickly it moves on.

There are two broad routes. In a supplier-funded arrangement, suppliers pay the managing organisation a share of what they bill, so the buyer sees no separate line item. In a client-funded arrangement the buyer pays a management fee directly. Supplier-funded looks free and is not: suppliers either price the deduction into their rates or absorb it out of margin, and either way it appears somewhere in what you pay. The route also shapes behaviour, because a supplier-funded arrangement ties the programme's revenue to the volume of spend flowing through it, which is worth being conscious of when the programme advises on whether that spend should grow. Client-funded makes the cost visible and the incentives easier to align, at the price of a budget line somebody defends every year.

The common failure is not choosing wrongly; it is not noticing there were two choices. A provider arrives with a platform bundled, or a platform arrives with an implementation partner attached, and the buyer evaluates the pairing as a single product. Later the service relationship turns out to be the part that is working badly while the software is fine, or the reverse, and unpicking them means renegotiating both at once. Evaluate the service model on how your programme should be run and by whom, and evaluate the platform on the record it keeps and the rules it can enforce. If the same organisation wins both, that is a reasonable outcome reached honestly rather than a decision made by default.

The service model, in most cases, because it determines who will be using the platform daily and therefore what the platform has to be good at. A programme your own team runs needs software your team can configure and administer without a specialist. A programme run for you needs software that gives you visibility and an export you can rely on, since you will be reading the record rather than maintaining it. Deciding the platform first tends to constrain the operating model to whatever that vendor happens to support, which is how organisations end up running a programme in a way nobody chose.

Data ownership, first and hardest. Assignment records, rate history and supplier performance are commercially valuable, and you will want them if the arrangement changes — so agree in advance what gets exported, in what format and within what period after termination. Then agree who is accountable for what: which decisions belong to hiring managers, which to the programme, and where a hiring manager can override. Set out how suppliers are added to and removed from the panel, and on whose evidence. Programmes that skip these settle them later under pressure, at the point where somebody wants to leave and discovers the record is harder to retrieve than they assumed.
