A business bid or tender is a way of winning business for you, and as such, it needs to be well written. You need your writing to be completely accurate, and you need to be using the right type of language to achieve the results you want to achieve.
When you submit a tender, it will need to outline all the ways in which your business is right for the contract. You should use highly professional language, as well as good imagery, demonstrating the ways in which you can meet the needs of the contract.
Make sure you have your tender or bid professionally proofread as well – this is not a type of writing where mistakes will be permitted. You will need to check that everything is accurate and that you have answered all sections of the tender as compellingly as possible, giving a favourable and positive impression of your business.
