When bidding, the following documents will be used: preparing tenders can help you win big contracts, but it can also take time, cost money and commit valuable resources. If you don`t get the contract, money and waste of time are usually wasted, so you need to carefully evaluate whether or not an offer is worth a tender. Make sure the customer is serious and that you are not there to create the numbers or test the market. Sometimes customers are only looking for ideas that they use for themselves. You can prevent this by inviting customers to sign a confidentiality agreement before the offer is submitted. But don`t forget that a lot of customers really want you to make a creative contribution and give ideas. The Chartered Institute of Procurement – Supply believes that “if it is carried out in a professional and ethical manner, … Post-auction negotiations are an appropriate procedure for ensuring value for money.  Even if you don`t win the job this time, writing a tender can clarify your goals, strengths and weaknesses and you can learn for the next time by asking for feedback on your offer. It increases your profile with the customer and helps you learn more about customer needs. An ITT is generally expected to comply with a standardized structure to ensure impartiality, and the winner of the offer is entitled to assume responsibility for the formalities of the order documents and to pay all tendering costs for the official registration.
[Citation required] A dual-conversion system can be used in an open bidding or bidding system. The double envelope system separates the technical proposal (based on the declaration of work and which must correspond) from the funding or cost proposal in the form of two separate and sealed envelopes. During the evaluation of the tender, the technical proposal would first be opened and evaluated, followed by the funding proposal. The aim of this system is to ensure a fair assessment of the proposal. The technical proposal would be evaluated only on the basis of its technical advantages and its ability to meet the requirements set out in the invitation, without being excessively distorted by the financial proposal. ITTs can be distributed to potential bidders through a tendering service, so that companies can receive and search for live offers from a number of public and private sources.
