Personally, I work out how much it'll cost to clean/manage the premises then add 10-20% for profit.
I don't know if anybody else uses a formula or goes by metre sq etc. Carpet cleaning, stripping and sealing etc. I guess you'd have to quote by area due to chemical coverage.
I always ask about their current cleaning arrangements. If they are having 2hrs mon-fri then you can work out your wage cost, then add holiday pay, a bit for training staff, a bit for uniforms, management, insurances, cleaning materials etc.
Each contract is slightly different. More mopping = more cleaning chemical whereas with vaccuuming you buy 1 hoover (if that makes sense)
Then again, I've been running my business for under 12 months so I may be talkin crap!
Have you done a search on this forum, a lot of people are getting annoyed with the same questions?
Hope I've helped a bit
Paul
