What to include in a quotation: First of all, a quotation should include the price that you have decided to charge for the service or goods you will provide. In a quotation, you can include a breakdown of the components leading to the settled price (such as labor costs, raw material costs, VAT etc.) You may also want to specify a time schedule: i.e. how long the project will take you or how long it will be until goods are delivered.
A quotation may also indicate a specific time period for which it is valid, e.g. 30 days. Also, a project or service quotation may include an explanation of how any requests for modifications or changes will affect the price once the project is underway.
