Office managers, workplace leads, and executive assistants who own the vendor list.
What usually goes wrong
The usual failure is a crew that brings a house-cleaning habit into a workplace: desks disturbed, a different person every night, and no one who can say whether the 14th-floor kitchen is on tonight's route. Frequency gets agreed in a sales call and then drifts.
What the contract covers
- Workstations, meeting rooms, and kitchens
- Washrooms every visit, with soap and paper in the contract or drawn from yours
- Reception glass and the entrance mat
- A day porter only when headcount and washroom count justify a person on site
How it is usually scheduled
Most offices land on five evenings a week. Smaller suites often do two or three. A headquarters with a busy lunch room sometimes adds a midday porter and keeps the real clean at night.
