I dont work out my tenders by the hour.....as all are different to each other.
I remember reading somewhere that each "account" is like a fingerprint.....when it comes to cleaning, no two "accounts" are alike.
So i try to do a thorough survey of the customers premises.....then, like every one else i determine the amount of labour that is needed to complete the job.
Once i have done that, i look at my notes and work out what cleaning materials, equipment etc that i would roughly use in a year.
Also included would be holiday pay, Uniforms, Insurance costs, Administration charges, Management fee (my wages - usually around 2 hours per week.....but would depend on the size of the contract and how long i will be there for the weekly visit), training....usually try to account for 15 hours per year per employee....and not forgetting a hanson profit ontop :
After i have come to a grand total, i then double check my figures by determining the % of labour - i try to get to Karls suggested 57%.....but the two contracts i have done have varied between a 55% one and a 61% one.
The system i like to use above, was the same system i used quite comfortably when i ran my own cleaning business up till 3 years ago.....However, if i had time to do the maths, i may be surprised to find that the average cost per hour may well be similar for each contract......
It would be fun to find out the average price per square footage of a typical commercial enviroment to triple check the figures......but i like it complicated......and have a feeling that this was discussed around a year and a half ago.
Any one have a price on the average square foot for cleaning??
