Most duplicated software

Software duplication rankings (2026)

Tool duplication occurs when an organization pays for multiple software applications with overlapping functionality. Vertice's Q3 2026 data shows the full ranking unchanged from Q2 for the first time this year, with Development holding the #1 spot. Duplication is easing slightly across every category, but it remains a significant, persistent cost.

• Development holds #1, ending the back-and-forth with Security. After the two categories swapped places in both Q1 and Q2 2026, Development has kept the top spot for a second consecutive quarter. The average customer now runs 7.18 separate Development contracts, compared with 6.54 for Security.
• Duplication has dipped across the board. Every category recorded a lower average number of contracts per customer than in Q2, with declines of between 5.7% and 6.7%. Security saw the largest drop, from 7.01 to 6.54 contracts. This may be early evidence of consolidation efforts, but the overall picture is still one of widespread overlap.
• The bottom three remain completely stable. Collaboration & Productivity, Marketing and Sales Tools have now held the same ranks for four consecutive periods. Even the least-duplicated category, Sales Tools, still averages more than four contracts per customer, a reminder that duplication is a baseline issue, not one limited to technical teams.

The cost of duplicate software

• Direct financial waste: Every duplicate application represents a missed opportunity for volume discounting. By maintaining multiple vendors for the same function, organizations fail to reach the spend thresholds required for enterprise-level pricing. Shelfware and underutilization also represent substantial financial loss: companies with 500-1,000 employees waste $1.7M on these tools every year, a figure that increases with company size.
• Decentralized buying friction: Duplication is frequently a byproduct of decentralized procurement. When individual teams or departments buy their own preferred tools without cross-functional visibility, the organization ends up paying for the same features multiple times under different contracts.
• Increased security risks: Every redundant application is an additional entry point for potential security threats. Multiple tools performing the same function can lead to fragmented logging, conflicting security protocols and "blind spots" in governance.
• Operational inefficiency: Duplicate software forces employees to manage data across multiple silos, leading to "toggle tax", the productivity loss associated with switching between apps to complete a single workflow.

Procurement platforms with usage analytics capabilities can flag feature overlap or outright duplication, helping to inform decisions on whether to rightsize, consolidate or terminate contracts at the point of renewal.
