Short answer

Normalize every proposal against the same areas, tasks, frequencies, service windows, exclusions, supplies, and quality process. The monthly price only becomes meaningful after the scope is aligned.

Create one comparison sheet

List every required area and task, then record how each bidder addresses it. Highlight missing frequencies, assumptions, and optional charges instead of relying on proposal summaries.

Check labor assumptions indirectly

You may not receive staffing details, but scope depth, frequency, building access, service window, and periodic tasks reveal whether the proposed plan is realistic.

Read exclusions and added-work language

Look for limits around glass, high work, supplies, floor projects, construction residue, emergency calls, event cleanup, and newly added areas.

  • Included work
  • Excluded work
  • Periodic work
  • Approval process
  • Pricing for changes

Evaluate management fit

Confirm the main contact, issue-reporting path, quality review, start-up process, and how the provider handles a facility that changes over time.

Frequently asked questions

What if proposals use different frequencies?

Reprice or compare them on a common cadence. Otherwise the totals do not represent the same service.

Should I ask for a revised proposal after questions?

Yes. Important clarifications should appear in the final written scope rather than remain in an email thread or conversation.
