Fixed Budget Selection (FBS)

Fixed Budget Selection (FBS) is a consultancy procurement method where the procuring entity sets a firm, non-negotiable budget ceiling and awards the contract to the technically highest-scoring firm whose financial proposal falls within that ceiling. It inverts the usual logic: quality wins, not price, as long as cost stays within the fixed limit.

What is Fixed Budget Selection in government procurement?

FBS is one of the selection methods available under standard consultancy procurement guidelines, including those of the World Bank and various Indian government bodies. It is specifically suited to situations where the procuring entity has a hard budget that cannot be exceeded, and getting the best possible technical quality within that budget is the priority.

The process starts with a technical evaluation identical to QCBS. All firms submit technical and financial proposals in separate sealed envelopes. Technical proposals are opened first and scored against the stated criteria covering firm experience, key personnel, and methodology. Once all technical scores are recorded, financial proposals are opened. Any firm that has quoted above the disclosed budget is eliminated. Among the remaining firms, the one with the highest technical score wins the assignment.

The budget ceiling must be disclosed in the Request for Proposal before submission. This transparency is critical: firms can calibrate their staffing and effort to offer the strongest possible team within the known budget rather than guessing. If the government keeps the budget secret, the method cannot function as intended.

FBS is rarely used for large, complex assignments because a rigid budget can exclude the most capable firms if they cannot fit into the ceiling. It works best for smaller assignments with a clearly defined scope and a well-calibrated government estimate.

Why it matters for bidders

FBS creates a different competitive dynamic from both L1 and QCBS. Price does not win; technical score wins. But a firm quoting above the disclosed ceiling is eliminated entirely, regardless of how strong its technical proposal is. So the financial proposal must be at or below the ceiling, and the technical proposal must be the best among those that are.

For bidders, this means two things. First, read the disclosed budget carefully and design your staffing plan to be fully deliverable within that amount. Do not over-staff to impress: any proposal above the ceiling is disqualified before technical scores matter. Second, invest heavily in the technical proposal quality, since that is the actual differentiator. Key personnel selection, methodology detail, and demonstrated relevant experience are what separate the winner from runner-ups among qualifying financial proposals.

If the disclosed budget seems unrealistically low for the scope, raise the concern at the pre-bid meeting or through a written query. A budget that most competent firms cannot meet will result in very few or no qualifying proposals, forcing a re-tender.

Example

A ministry issues an RFP for an IT system audit under FBS with a disclosed budget of Rs 40 lakh. Four firms submit proposals. On technical evaluation, the scores are 88, 82, 76, and 71. When financial proposals are opened, the firm scoring 88 has quoted Rs 47 lakh (above ceiling, eliminated), the firm scoring 82 has quoted Rs 38 lakh (within ceiling), the firm scoring 76 has quoted Rs 35 lakh (within ceiling), and the firm scoring 71 has quoted Rs 40 lakh (within ceiling). The firm scoring 82 wins because it is the highest technical scorer among the three firms within the budget, even though it is not the cheapest.
