Put a national rollout to tender and three different species of company will bid, often at three very different prices. The managed service provider you already know. The on-demand technician marketplace with impressive coverage maps. And the deployment specialist you may not have heard of, because the category is quieter than its work. All three can produce a plausible proposal. They are built for different jobs, and the mismatch costs are paid in the field, months later.
A good MSP knows systems deeply and knows your environment personally, which is exactly what ongoing operations need. What most MSPs lack is a field organisation: their strength concentrates where their engineers sit, and a 400-site national program needs consistent execution in places no MSP has ever visited. The common result is an MSP running the project layer while subcontracting the field layer at margin, sometimes to the very marketplaces below, leaving the client paying twice for one accountability. MSPs belong in the rollout as the design authority and the receiving support organisation; asking them to also be a national field force is asking a surgeon to run the ambulance network.
Technician marketplaces solve one problem brilliantly: a competent stranger at almost any postcode, tomorrow. For single visits, that is the product, and it works. For programs, the model's economics work against you: each job is priced and accepted individually, each technician arrives fresh with no playbook, no staging feeds the visits, and no one in the chain owns the outcome across sites. Consistency, the entire point of a standardised estate, becomes a per-visit lottery. Marketplaces are capacity, not capability. Programs need both.
A deployment specialist is constructed around the program shape: integration centres that stage and kit hardware, field crews rehearsed on piloted playbooks, wave scheduling, exception management, and governance that reports weekly in a form a steering committee can act on. The specialist's weakness is the mirror of the MSP's: they will not manage your servers or answer your users on Tuesday. They exist for the multi-site deployment itself, plus the field support that keeps the estate running afterwards.
Fewer than a dozen sites, or work concentrated where your MSP is strong: let the MSP run it. Genuine one-off visits with no consistency stakes: a marketplace is efficient. A program, dozens to hundreds of sites, hard deadlines, one required outcome everywhere: a specialist, with your MSP as design partner and the selection rigour any national commitment deserves. The in-house option rounds out the table for organisations with standing field teams, which is to say, few.
The failure pattern to avoid is choosing by familiarity or by price alone. The MSP is familiar; the marketplace is cheap; the program does not care about either. It cares about who has done this shape of work before, and can prove it.
