Abstract
This paper presents findings from an analysis of competitive procurement events conducted through the Bundle IQ platform between January 2025 and March 2026. Drawing on transaction data from 40+ competitive sourcing events across seven major indirect spend categories, we report average savings of 19% against incumbent pricing, with significant variation by category, procurement route, and degree of supply market competition. We examine the relationship between specification quality, vendor response rates, and savings outcomes, and identify the conditions associated with highest-value procurement interventions.
Data note. This paper draws on Bundle IQ's initial transaction dataset of 40+ competitive events (Q1 2025–Q1 2026). This is an early-stage sample. Bundle IQ publishes updated findings quarterly as the transaction dataset grows. Current findings should be treated as indicative benchmarks rather than statistically definitive conclusions. The methodology established here is applied to the full transaction dataset as the platform scales. Read the full methodology →

1. Methodology

Data was collected from 40 competitive sourcing events conducted January 2025 – March 2026. Events were included where: (i) a baseline or incumbent price existed; (ii) at least two vendor responses were received; (iii) a contract was awarded. All savings are calculated as the percentage difference between baseline price and contracted price. All data is anonymised.

Methodology Note
Sample note: 40 events is an early-stage dataset. Findings should be treated as indicative. Bundle IQ publishes updated benchmarks quarterly as the transaction dataset grows. Current findings are consistent with the academic literature on SME competitive sourcing outcomes.

2.1 Savings by category

2.2 The contract age effect

Contracts not competitively tendered for three or more years showed average savings of 26%, compared to 14% for those tendered within the previous 18 months. This supports the hypothesis that incumbents systematically exploit renewal inertia to maintain pricing above competitive market rates over time.

"The single strongest predictor of saving magnitude was not category, spend level, or market structure. It was how long the contract had been running without a competitive challenge."

2.3 Specification quality and response rates

Events with high specification completeness scores averaged 4.2 qualified responses; events with low scores averaged 1.8. Higher response rates were associated with better saving outcomes — consistent with basic competitive market economics. Investing in specification quality before going to market systematically improves outcomes.

3. Demand Aggregation Evidence

The two energy pool events included produced savings of 24% and 32% respectively versus individual incumbent pricing — significantly above the 14% average for individually-tendered energy contracts. This is consistent with the theoretical literature: combined volume creates pricing leverage individual SMEs cannot achieve independently.

4. Process Efficiency

A survey of 24 buyers who had used Bundle IQ for at least one competitive event found their previous unstructured approach took 8–14 hours of internal management time. The equivalent process through Bundle IQ took an average of 1.2 hours. At a conservative opportunity cost of £45/hour, the process efficiency alone represents £315–585 per procurement event before any commercial saving is counted.

5. Conclusions

Average savings of 19% against incumbent pricing, achieved across 94% of competitive events, represent a material improvement in procurement outcomes. The contract age effect has important practical implications: the highest-value interventions target contracts running longest without competitive review. Bundle IQ's contract register and renewal flagging is designed to identify exactly these contracts.
