Bid and proposal management
One place for every bid, from the opportunity to the outcome.
Tairga runs the whole life of a bid: finding the tender, deciding whether to bid, planning, writing, review, approval and submission. Cora, the assistant, helps at each step and shows the source of every fact. People decide.

Who Tairga is for
For bid and proposal teams
Public sector tenders in the UK and New Zealand
For bid managers, bid writers, proposal managers and the directors who approve. Run RFIs, PQQs, SQs, ITTs and full written proposals, across several bidding entities and joint ventures.
Bid managementFor equipment packagers
Compressors, pumps, heat pumps, generator sets and more
For proposal and applications engineers. Configure a package by choosing options, and get the technical proposal, datasheet, P&ID and exclusions from those choices.
Package BuilderBid management
Every live bid, stage by stage, with the gates enforced.
Bids move through Qualify, Go / No-Go, Writing, Approval and Submitted on the Bids board. A bid cannot pass a gate until its checks are met. Each bid has its own workspace, grouped by phase: Prepare, Understand, Decide, Write, Assure and Close.



How proposals are really run
Built on APMP and Shipley practice.
The steps your team already knows, in one workspace:
- Go / No-Go and win themes
- Answer plans and storyboards before anyone drafts
- Pink, red and gold colour-team reviews
- A compliance matrix that maps every requirement to its answer
- Approval, outcome and lessons learned

Cora, the assistant
Cora writes with you, and shows its sources.
Ask Cora is on every page, scoped to you, to the bid or to the open document.
Every fact cites its source
Each factual statement links to the line it came from, in the tender pack or your knowledge library.
Quotes and figures are checked
A fact-check pass runs before anything is accepted, so numbers and quotations match their source.
People decide
Nothing is automated end to end. A person accepts or rejects every suggestion Cora makes.
Cora also reads the client's documents to start a new bid, drafts and refines answers, summarises meetings and tender packs, and suggests register items and lessons learned.
Package Builder
Choose the options. Get the proposal.
For packagers of compressors (API 618, 619, 617), pumps (API 610, 674, 676), refrigeration and heat pumps (EN 378), generator sets (ISO 8528, API 616), cooling water skids, air and nitrogen systems (ISO 8573-1) and lube and seal oil consoles (API 614). Rules keep the choices consistent and show why. The outputs come from the same configuration, so they agree every time.
