Bid
A bid is a supplier’s offer to provide goods, works or services under stated requirements. In public procurement, people often use bid and tender interchangeably, but the opportunity documents determine what the response must contain and how it will be assessed.

When a buyer asks a supplier to compete for work, the supplier’s written offer is usually called a bid. In UK public procurement, bid, tender and tender submission are often used as practical synonyms. The exact label matters less than the instructions in the tender notice, invitation and associated documents.
What a bid usually contains
A bid may include a completed response form, method statements, evidence of experience, pricing schedules, declarations and supporting documents. The buyer should evaluate it against the published requirements and award criteria. A persuasive answer cannot cure a failure to meet a mandatory condition or a late submission.
Read the pack as one set. Check the submission route, file limits, question order, clarification process, contract terms and deadline. Keep an evidence trail for assumptions and approvals. If a requirement is unclear, ask through the stated channel so the buyer can decide whether to share an answer with all bidders.
Bid, quote and tender
Every organisation uses these words slightly differently. A request for quotation may focus on price for a defined need, while an invitation to tender can involve quality questions and a formal contract. Neither name alone tells you the evaluation method.
For example, a council’s bid may score a delivery plan, social value and price. The lowest price is not automatically successful where the published criteria assess the most advantageous tender.
