Bid
A bid is the formal commercial and technical offer that a supplier submits to a contracting authority in response to a procurement opportunity. The bid sets out the supplier's proposed price, delivery terms, technical approach, qualifications, and supporting evidence. Once submitted, a bid is legally binding for the period specified in the procurement documents.

Bid versus tender: what is the difference?
In everyday business language, bid and tender are often used interchangeably. In strict procurement terminology, however, the words describe slightly different things. A tender refers to the structured document and the entire procurement process, while a bid emphasises the commercial offer itself. In the United Kingdom and Europe, tender is the more common term. In the United States, bid is the dominant term, especially in construction and federal contracting.
Both terms describe the same underlying activity: a supplier formally offering to deliver something at a stated price under stated conditions, in response to a buyer's published need. For practical purposes, a bid and a tender are the same artifact viewed from different angles.
What a winning bid contains
A complete bid usually includes a covering letter, a technical proposal explaining how the supplier will deliver the work, a financial proposal stating the price and payment terms, evidence of qualifications, financial statements, references from similar past contracts, and any required certifications. Some bids also include a tender bond, which is a financial guarantee that the supplier will honour the bid if selected.
The technical proposal is often the deciding factor in higher-value contracts. Buyers want to see that the supplier understands the problem, has a credible methodology, has appropriate staff, and has realistic delivery timelines. A strong technical proposal demonstrates expertise without being padded with marketing language. Specific examples, named team members, and concrete deliverables carry more weight than generic claims.
Bid evaluation: how the winner is chosen
Most public bids are evaluated against the Most Economically Advantageous Tender, often abbreviated as MEAT. Under MEAT, the buyer scores each bid against published criteria such as price, quality, delivery time, environmental impact, and technical merit. The bid with the highest combined score wins. Pure lowest-price evaluation is also possible but is increasingly rare in modern public procurement.
Evaluation panels usually consist of three to seven officials, including subject matter experts, procurement professionals, and sometimes external advisors. They score each bid independently and then reconcile their scores in a panel meeting. The process is documented in detail, and unsuccessful bidders have the right to receive feedback explaining why they did not win.
Common reasons bids fail
- Non-compliance with mandatory requirements such as missing certifications or late submission.
- Incomplete documentation, including missing signatures, unsigned annexes, or wrong forms.
- Unrealistic pricing that fails the abnormally low offer test or the buyer's budget check.
- Weak technical proposals that fail to demonstrate understanding of the buyer's specific context.
- Insufficient references, especially when the buyer requires similar contracts of similar value.
Improving bid win rates
Suppliers who win consistently tend to be selective about which bids to pursue. Rather than submitting many low-quality bids, they focus on opportunities where they have a clear technical edge, prior relationships with the buyer, or a price advantage. Pre-engagement with the buyer during the market consultation phase, before the formal bid is published, is one of the highest-leverage activities a supplier can undertake.
