What bundling actually buys you
The administrative saving is real and often underestimated. One agreement, one invoice, one contact and one set of compliance documents to track is materially less work than four of each, particularly for an organisation where cleaning is somebody's secondary responsibility rather than their job. Consistency is the other gain, since a single provider applying one standard across the group is easier to manage than four different interpretations.
The commercial position usually improves too, though less dramatically than buyers expect. Volume helps a provider plan staffing and equipment, which they will price for. It does not remove the underlying cost of putting people in each building, so the saving comes from overhead and efficiency rather than from the labour itself. Expect a modest improvement rather than a transformative one and volume alone will not change that arithmetic.
