Built for every supplier
Solo, startup, agency or enterprise. Same OS.
Tender.OS is the supplier-side operating system for winning UK public contracts. Use it as a one-person bid desk, a founding team, a delivery agency, or a national practice. The workflow does not change with the size of the room.
Solo players
Bid without a proposal team. Qualify, draft and evidence from one workspace.
Startups
Find the first public contracts you can actually win, and skip the ones you cannot.
Agencies
Keep discovery, qualification and submission packs in one place across live bids.
Enterprise
Company Brain, evidence trails and a shared pipeline for practices that bid every week.
