Economic scoring in Spain

Why the economic scoring formula matters in Spanish public procurement

An extreme price reduction can distort the intended behaviour of a formula and undermine the purpose of the tender: selecting the bid offering the best value for money. TenderLab lets you compare formulas, confront theory with actual outcomes and simulate their effect on contract award decisions.

Which price scoring formula is best suited to selecting the best tender?

Compare formulas, theoretical curves and anonymised real cases to see how price points are distributed and how extreme price reductions affect the result.

Does it make sense to bid the price reduction your business can actually sustain?

Simulate bids using realistic costs and delivery capacity to understand your competitive position under a specific Spanish tender formula.

Formula, curve, bids, scores and contract award

The Formula Lab explains the theoretical behaviour of each equation. The Case Analyzer applies it to anonymised completed Spanish tenders and lets you test changes without altering the original data. In TenderLab, price reduction means the percentage by which a bid is below the tender base price (Spanish: baja).

Why TenderLab?

Allocating 20, 30 or 40 points to price does not determine how those points will actually be distributed. The formula selected and the bids ultimately submitted can compress or amplify economic differences and alter the balance between price and quality. TenderLab makes that effect visible both before and after bids are opened.
