What is consumables?
Consumables are the items used up in delivering a cleaning service — soap, paper, bin liners, chemicals — supplied either by the contractor or by the client depending on the contract.
Who supplies them is a question that must be settled explicitly, because it changes the price substantially and because the gap between the two assumptions is where disputes start.
Where the contractor supplies them, usage is a real cost variable: a building's occupancy changes and consumption with it, and a fixed price agreed on old assumptions erodes.
Running out is a service failure in the occupant's eyes regardless of whose responsibility it was, which is why stock checks belong in the task list rather than in a separate process.
In practice
A washroom with no soap on a Monday morning.
The contract says the client supplies consumables. The client believes the contractor does. Neither party is lying and the cupboard is empty.
Who buys, who stocks and who notices are three separate questions, and contracts routinely answer only the first.
The complaint will go to the contractor regardless of what the contract says.
What goes wrong in practice
- Responsibility for supply left ambiguous in the contract.
- Usage never tracked, so pricing is based on an assumption that has drifted.
- Stock checks not part of the routine, so shortages are found by occupants.
