Your budget should show how you have arrived at your total price. Your largest cost will be your labour, so we will want to see who you are allocating to the project (names and job titles), how many days they will work on it and what their day rate is.
If you also have additional direct costs associated with the project, you will need to detail these as well. Finally, if you are VAT registered you will add VAT to the total, and this total must be no more than the maximum price that we have specified for the project.
Here is a template that you can use for your budget.
For all open briefs, the maximum costs will be included within the details of the brief.
