Tender, bid, proposal, quote, solicitation — five words for parts of the same activity, used loosely enough that people rarely stop to distinguish them. Most of the time that’s fine. But the terms do carry different emphases, and knowing them helps you read what a buyer actually wants.
- Tender— the buyer’s formal invitation to compete, and the process around it.
- Bid— the supplier’s priced offer submitted in response.
- Proposal— the supplier’s response when approach and value matter, not just price.
In practice “tendering,” “bidding,” and “submitting a proposal” all describe responding to an opportunity — the difference is emphasis and region.
A tendermost precisely means the buyer’s formal invitation to compete for a contract — often an ITT (invitation to tender)— and by extension the whole competitive process. Confusingly, “submitting a tender” also refers to the supplier’s response, so the word covers both sides. It’s the default term in UK, EU, and Commonwealth public procurement.

A bid is the offer a supplier submits — with the emphasis on priceagainst a defined requirement. “Bid” fits best where the buyer has specified exactly what they want and is comparing offers largely on cost (much like an RFQ). “Bid team,” “bid/no-bid decision,” and “bid manager” are standard regardless of the document’s formal name.
A proposal is what you submit when the buyer is evaluating your approach and value, not just your price — the response to an RFP. Proposals carry narrative: method, team, experience, and win themes mapped to weighted criteria. The heavier the evaluation, the more “proposal” is the right word.
From document to plan
Whatever it's called, qlows extracts the requirements into a grid before you write.
Tender, bid, or proposal — the prep step is the same, and it's where wins are decided.
See how it works →The biggest source of confusion is geography, not meaning. The UK, EU, and Commonwealthlean on “tender” and “ITT”; the USleans on “bid,” “proposal,” and “solicitation.” They point at the same activity — competing for a contract on published terms. If you sell across borders, expect the vocabulary to switch by market; the international tenders guide covers how the process itself stays recognisable underneath.
