Who delivers, and in what composition
A sourcing model describes how service delivery is composed in the market: from fully employed staff to one integrated party. It does not describe who carries responsibility, nor how payment is arranged — those are different variables.
The sourcing continuum
Ten models, ordered from fully self-delivered to fully externally integrated. The order is a spectrum of market composition, not a ranking of quality.
- 01
Fully in-house
No FM activity is contracted externally; the demand organisation employs its own technical and soft-service staff directly.
No FM activity is contracted externally; the demand organisation employs its own technical and soft-service staff directly. Rare at scale today outside asset-heavy sectors (utilities, some healthcare estates, defence) because it concentrates specialist-labour risk inside a non-FM core business.
The trade-offAdvantage: total control over standards and continuity; disadvantage: exposes the organisation to labour-market and specialist-skill risk it has no expertise pricing.
Typically combines with - 02
Single-service outsourcing
One service contracted to one specialist, with its own contract and its own supplier relationship.
One service (cleaning, security, lift maintenance) contracted to a specialist provider, each service typically with its own contract and its own supplier relationship. Common where a service has a genuinely distinct specialist market (lift maintenance is the clearest case — manufacturer-tied servicing).
The trade-offDownside compounds with scale: an estate with fifteen single-service contracts has fifteen SLAs, fifteen escalation routes, and no single point accountable for how they interact on site.
- 03
Bundled services
A small number of related services under one contract with one provider, short of full integration.
A small number of related services (typically hard-services bundles, or soft-services bundles) combined under one contract with one provider, without going as far as full multiservice integration. A common intermediate step when an organisation wants fewer supplier relationships without committing to single-provider IFM.
- 04
Multi-service
One provider delivers most or all services, without taking on integration responsibility.
Most or all FM services delivered by one provider under one contract, but without that provider taking on management-led integration responsibility — it delivers a wide service list, but the demand organisation (or its regieorganisatie) still does the cross-service coordination.
Category cautionDistinct from IFM in exactly this way: multi-service is breadth of delivery; IFM is breadth of delivery plus delegated integration.
Typically combines with - 05
Managing agent
A third party manages and coordinates other suppliers on the client's behalf, without delivering services or holding the contracts.
A third party manages and coordinates other suppliers on the client's behalf without itself delivering services or holding the service contracts — the client contracts directly with delivery suppliers, and the managing agent is paid a management fee, not a margin on service delivery.
The trade-offThis separates delivery risk from coordination risk, at the cost of an extra relationship layer.
Typically combines with - 06
Management contractor
Like a managing agent, but the contractor holds the service contracts itself and carries commercial risk.
Similar to a managing agent but the contractor does hold the service contracts (contracts with suppliers in its own name, not the client's), taking on more commercial risk and typically earning a margin rather than a flat fee.
The trade-offThe client has one contractual counterparty for everything, at the cost of less direct visibility into supplier terms.
Typically combines with - 07
Main contractor
One provider takes primary contractual responsibility and subcontracts specialist services beneath it.
One provider takes primary contractual responsibility for FM delivery and subcontracts specialist services beneath it, similar in structure to construction main-contracting. Common where an organisation wants one throat to choke but the underlying delivery is inherently multi-specialist.
- 08
Integrated Facility Management (IFM)
One provider delivers the full range of services and takes on management-led integration.
One provider delivers (directly or via its own subcontracted supply chain) the full range of FM services and takes on management-led integration — service design, cross-service coordination, single performance framework — that a demand organisation would otherwise have to do itself via a regieorganisatie.
Category cautionThis is the platform's clearest example of a term used in the market as a sourcing concept, a provider proposition, and (loosely, incorrectly) an operating model all at once — flagged here directly rather than resolved by picking one meaning.
Typically combines with - 09
Total Facility Management (TFM)
Used in the market largely interchangeably with IFM, sometimes implying single-invoice, single-KPI-set simplicity.
Used in the market largely interchangeably with IFM, sometimes with an added implication of single-invoice, single-KPI-set commercial simplicity. Treat as a close sibling term to IFM rather than a distinct category.
Category cautionNote the overlap explicitly instead of forcing an artificial distinction the market itself doesn't consistently maintain.
Typically combines with - 10
Outcome-based / performance-based contracting
The commercial and performance framework, not a delivery-scope category.
The commercial and performance framework, not a delivery-scope category — it can overlay single-service, bundled, multi-service or IFM arrangements. Payment and contract continuation are tied to measured outcomes (uptime, satisfaction, energy performance) rather than to inputs delivered or activities completed.
Category cautionGenuinely harder to specify and audit than input-based contracting, which is exactly why it is rarer in practice than its popularity in RFPs would suggest — a gap between rhetoric and practice worth naming, and one of the platform's more defensible provocations.

IFM: three meanings behind one acronym
Integrated FM is one of the few terms in the discipline whose meaning depends on who uses it. That is not market sloppiness but a genuine disagreement, and this platform does not resolve it by declaring one definition.
Here IFM is a way of composing supply: several services with one contracting party, with integration as an explicit contractual task alongside delivery itself. Used this way, IFM sits beside bundling and multi-service and says nothing about the client's internal organisation.
In the market IFM is often the name of a service package: an offer with one account structure, one report and one platform. Its content varies by provider, and the integration sometimes sits in the provider's organisational structure and sometimes only in the invoice and the management report.
Some authors and clients use IFM for the configuration of the FM organisation itself: a model in which the client does not perform integration but purchases it. In that reading IFM touches the choice between regie and demand organisation, and is therefore far more than a procurement form.
Practical consequence: in any conversation about IFM, ask which of the three meanings is intended, and ask explicitly who performs the integration, on what information and at whose risk. Without that answer, parties compare offers that are not about the same thing.
In-house (retained) delivery organisation
FM is largely self-performed: internal teams own both delivery and the management of it.
Directed external deliveryRegieorganisatie — managing organisation / intelligent client function
The organisation retains demand translation, specification and supplier governance; only execution sits outside.
Full external integrationDemand organisation
The organisation retains only the translation of core business need into FM requirements; both FM management and delivery sit externally.
