The office is quiet before the workday begins, which makes small cleaning faults easy to notice. Coffee rings remain on the meeting table, fingerprints show on the entry glass, and the kitchen bin is already full. If visitors are due later, a quick search for a cleaner can feel like a rushed decision.
Start by noting the rooms that attract complaints, the days staff are present, and the tasks employees currently do themselves.
Include details such as carpeted areas, toilets, kitchen appliances, internal glass, shared desks and any spaces that are rarely used. That record gives each provider the same brief and makes quotes easier to compare.
