Unilog.SC Publishes June 2026 Industry Research Report, Revealing the Network Design Flaw Behind Rising Spare Parts Costs and Customer Escalations

New research reveals why spare parts inventory and customer escalations are rising simultaneously, identifying service parts network design as the key driver of service performance and aftermarket profitability

LYNBROOK, N.Y., June 25, 2026 (GLOBE NEWSWIRE) -- Unilog.SC, a leading global supply chain design and execution company, today published its June 2026 Industry Research Report, Service Parts Network Design, examining why spare parts inventory and customer escalations continue to rise despite increasing investment. The report identifies network design, not inventory investment, as the critical factor in translating service commitments into customer outcomes and aftermarket performance.

According to the report, manufacturers tie up approximately 10% of annual sales in spare parts inventory. Meanwhile, customer satisfaction with after-sales support runs 10 to 15% below expectation. In many networks, nearly half of service calls are delayed because the required part is not available in the right location when needed.

“The industry has spent years focusing on inventory levels, SLAs, and cost reduction, but many organizations are still struggling to improve service outcomes,” said Eyal Yossef, VP Supply Chain Solutions at Unilog. “Our research shows that network design, not inventory investment, is what determines whether service commitments translate into customer uptime and profitability. The companies that will outperform over the next decade will be those that treat service availability as a designed outcome.”

The report highlights how many service organizations continue to measure performance using aggregate inventory and service metrics that obscure the parts and locations most critical to customer uptime. This often leads organizations to optimize for averages rather than service outcomes, creating hidden vulnerabilities that increase downtime risk, expedite costs, and pressure on aftermarket margins.

Key findings from the report include:

• Rising inventory and rising customer escalations are often a result of the same network design problem.
• Service parts networks should be managed as connected chains rather than traditional warehouse hierarchies.
• Parts stocking decisions should be based on criticality and demand variability, not just unit cost.
• Service-level agreements must be supported by differentiated stocking policies, replenishment strategies, and fulfillment models.
• Organizations that focus solely on average service performance can overlook high-impact failures tied to slow-moving, mission-critical parts that drive customer dissatisfaction, contract risk, and costly escalations.
  

These findings reinforce Unilog.SC's approach to service supply chain design and execution, which brings together network design, inventory strategy, transportation management, and operational execution to help organizations improve service availability while controlling working capital.
