A scope of work is the document that converts a verbal agreement into an enforceable one. Most cleaning disputes — missed tasks, billing disagreements, quality complaints — trace back to a scope that was never written down, or one that was too vague to be useful. This guide describes what a complete scope looks like.
The scope should open with a factual description of the facility: total square footage, number of floors, space type (office, medical, light industrial, multi-tenant), number of restrooms, break rooms, conference rooms and any specialised areas. This is the baseline against which every other item on the scope is measured. If the facility changes — a new tenant moves in, a floor is subdivided — the scope should be updated before the next service visit.
The most useful scopes list tasks by room or area, not by generic category. "Clean restrooms" is not a scope item. "Clean and sanitise toilets, urinals, sinks and mirrors; restock paper towels, toilet paper and soap; empty and reline waste receptacles; mop floor with disinfectant solution; wipe door hardware" is a scope item. The difference matters when a restroom is not cleaned to standard and both parties need to refer to what was agreed.
The scope should specify which tasks are performed on every visit and which are periodic. Standard nightly tasks happen every service visit. Floor stripping and waxing might happen quarterly. Carpet extraction might happen twice yearly. Each task should list its frequency explicitly. "As needed" is not a schedule.
For facilities with specific requirements — healthcare-adjacent spaces that need hospital-grade disinfectants, or facilities that prohibit bleach-based products near sensitive equipment — the scope should document which products are used in which areas. If a specific product is required, name it by category or approved product list, not by brand, so substitutions are managed proactively rather than discovered after the fact.
The scope should document the assigned crew lead's name, the access method (key, access card, building management code), required sign-in procedures, and the arrival window. If the building has a security system, the code and arming procedure should be in the scope. This section is what allows a supervisor to verify that the right crew entered the building at the right time.
A scope is as useful for what it excludes as for what it includes. If window washing is not included, say so. If the server room is off-limits, document it. If a tenant's private storage area is excluded, note it by room number. Exclusions prevent the assumption that anything not explicitly excluded is included.
The scope should state the monthly price, the invoicing schedule (typically the first of the month for the upcoming month's service), and the payment terms. Any periodic services — floor care, carpet extraction — should list their own pricing separately so the monthly invoice is predictable and the periodic services do not create billing surprises.
