Compare the two fictional office-cleaning quotes below. Use only the supplied text. First list facts that differ. Then list the questions we must ask before comparing total cost or scope. Separate not stated from excluded. Do not rank vendors, assume weekly means four visits every month, calculate savings, add tax or claim a final total. Keep the answer brief enough to review against the original quotes.

Quote A: $900 per month. Four visits per month. Vacuum office areas, clean two restrooms and empty trash. Cleaning supplies included. Contract length not stated.

Quote B: $850 per month. Weekly visits. Vacuum office areas and clean two restrooms. Cleaning supplies and trash service not stated. Twelve-month term.
