Without seeing what you actually submitted its a bit difficult
But whatever way you phrased it, you presumably specified an amount X per hour, per week, per visit of whatever
SO whatever it is X contains or should contain some or all of the following
- Labour cost ie what you will pay your employees
- Employer costs - NI contributions on above
- Materials - Chemicals etc
- Equipment - vacuum, scrubber dryer -
- Training
- Management Overhead
- Profit
etc
I have come across requests like this before but NOT in my cleaning experience
Actually, the more I think about, what I would do if I was you is go back to your prospect and ask THEM to specify how they want the costs broken down because whatever way you do it is likely to be different from the existing contractor and won't give them the ability to compare that they say they want.
I would also try to find out exactly what it is about the existing contractor that they are not happy with. If its the standard of cleaning then just getting him to reduce his price is unlikely to improve the quality of the cleaning. If its the price and the standard of cleaning is acceptable then you are possibly being used as a vehicle to get him to reduce his price.
As things stand its hard to see any up side for you
