A quotation should be set out something like this
QUOTATION
To provide cleaning works Mon to Fri
Charge per week £........ Plus VAT
52 weeks per annum
Charges are based on supplying services between Monday & Friday, all other days including Bank Holidays are excluded from this quotation (unless otherwise specified) and the necessary allowances have been made within our charges.
The above charge includes labour, supervision, chemicals and machinery. Janitorial goods such as black bags and paper products can be supplied at an extra cost.
This quotation has been prepared as a commercial bid with no provision for TUPE and we reserve the right to renegotiate the terms to cover any additional costs.
Terms & Conditions Apply
This is just one page of some of the info that you submit to commercial clients, small office contracts will obviously require less info in the quotation and personally I would not break down costs for these.
Hope this helps
