How to Calculate Commercial Cleaning Bids That Actually Win

DEFINITION

ISSA Production Rates

Standards published by the Worldwide Cleaning Industry Association defining how many square feet a single cleaner can complete per hour for specific cleaning tasks. Used in commercial cleaning bids to translate area size into labor hours rather than relying on flat per-square-foot estimates.

DEFINITION

Fully-loaded labor rate

The true hourly cost of a crew member, including wages, payroll taxes, workers compensation, benefits, and any direct supervision costs. Typically 25-50% higher than the base wage. Using wage-only in bid calculations leaves overhead and burden costs uncovered.

DEFINITION

Scope of work

The written document in a cleaning contract listing every task, area, and frequency covered by the agreement. Forms the basis of every bid. Tasks outside the scope cannot be billed without a change order or contract amendment.

DEFINITION

Burden rate

The percentage added to base wages to account for employer taxes, insurance, and benefits. For commercial cleaning companies, burden rates typically run 25-45% depending on state workers comp rates and benefits package.

Most cleaning companies lose money on contracts they bid too low to win. The fix is not better negotiation — it is a repeatable bid calculation that starts from actual costs.

This guide covers the method we designed SweepOps around. It works for any commercial cleaning operation, whether you use software or not.

Why square-footage pricing fails

Pricing by square foot ($0.10/sq ft, $0.15/sq ft) is a shorthand, not a system. It does not account for:

• Floor type (carpet vs. VCT vs. polished concrete)
• Restroom fixture counts
• Task complexity (standard office vs. medical disinfection protocol)
• Your specific labor costs and burden rate

Two 10,000 sq ft buildings at the same per-square-foot rate can have labor costs that differ by 40%. The flat rate ignores everything that actually drives cost.

The ISSA production rate approach

ISSA rates give you a time-based calculation instead of an area-based one. You are calculating how many labor hours the facility requires, then pricing those hours correctly.

This method produces bids that are defensible, consistent, and connected to your real costs. When you track actuals against bid hours over time, you can see where your estimates are wrong and improve them.

Using this in practice

The calculation above takes 2-3 hours for a first bid on a new facility type. Once you have bid similar facilities, the time drops significantly. Bidding software that stores production rates and labor cost inputs reduces it further.

The most important discipline is tracking actual time against bid time after you win an account. If your bids are consistently over or under in specific areas, the production rates or task list assumptions need adjustment.
