This Insight explores the top challenges, essential considerations and proven solutions for aftermarket parts providers to accelerate distribution operations and overcome challenges today and into the future.

Top challenges in aftermarket parts distribution

1) Manage high-volume inventory in limited space

Today’s vehicles are complex. Modern vehicles contain more than 30,000 parts,1 and that number is only growing with the rise of electric vehicles (EVs), advanced technology features and customization options. Parts distribution centers must support thousands of SKUs, from tiny components to bulky parts, across both new and aging vehicle models.

Industry reports indicate that people are keeping their cars longer. In fact, the average age of passenger cars in the U.S. has reached 14.5 years.2 Older cars require more frequent maintenance, replacements and repairs. This is great news for aftermarket parts providers—but only if they can meet the demand and allocate sufficient storage space.

Housing and handling more parts can lead to inefficient use of warehouse space, with many parts providers needing to add warehouse capacity. However, real estate is expensive, and expansion isn’t always an option. Optimized space utilization and smart strategies are now essential. Companies are turning to high-density storage solutions to maximize current facility space as SKUs increase, allowing distribution operations to accommodate larger inventories within the same physical space.

2) Ensuring order fulfillment accuracy and speed

Time is money. Automotive aftermarket parts are often ordered out of necessity when something needs to be repaired. The longer the lead time, the longer the repair takes to complete.

Aftermarket parts providers must seamlessly deliver the right parts to the right location at the right time. A fast turnaround time is crucial for aftermarket services because it directly impacts customer satisfaction, profitability and competitiveness.

Next-day and same-day shipping have become the standard. This puts immense pressure on warehouse operations to improve picking speed and reduce order cycle times with accuracy.

Traditional fulfillment processes struggle to meet these demands without errors or added costs. Instead, companies are overcoming these obstacles and optimizing operations by integrating software solutions including warehouse management systems (WMS), warehouse control systems (WCS) and warehouse execution systems (WES).

3) Workforce challenges are impacting productivity

Warehouses and distribution centers everywhere are struggling with hiring and retention. For aftermarket parts, the knowledge needed to handle part variants, warranty items and reverse logistics makes hiring even tougher.

Job openings have vastly outpaced job hires for the past decade, requiring companies to increase wages to attract potential workers. The lack of available workers leads to high turnover rates, which is often compounded by the physically demanding and repetitive nature of the work.

Understaffing and high turnover can also strain training resources, leading to inexperienced and undertrained staff. This increases the risk of safety issues in addition to reduced productivity and higher costs. As customer demands continue to increase, it’s important for companies to strike the right balance between labor and automation.

4) The rise in e-Commerce for aftermarket parts

E-Commerce now accounts for nearly 30% of U.S. aftermarket parts sales.3

Aftermarket parts providers often serve both professional installers and do-it-yourself (DIY) customers. Like in other industries, many consumers find it more convenient to search, compare and purchase their parts online with user reviews and competitive pricing right at their fingertips.

This shift requires distribution centers to modify their standard practices to meet the unique challenges of e-Commerce order fulfillment in addition to standard workflows. E-Commerce amplifies the need for fast, accurate deliveries and seamless order return experiences.

Modernizing distribution operations

Traditional distribution methods can’t keep pace with today’s growing demands. Technology, automation and smarter workflows are the way forward.

Implementing scalable and flexible technology solutions that can adapt to growing inventory will ensure accurate product tracking, increase capacity and streamline order fulfillment.

As you assess the readiness for optimization, consider the following:

  • Scalability: Can your current system adapt to growth in SKUs, order volume and customer expectations?
  • Flexibility: How well can your distribution operations handle a mix of part sizes, order profiles and service levels?
  • Visibility: Do you have real-time insight into inventory and process bottlenecks?
  • Capacity: Are you maximizing vertical space and storage efficiently?
  • Accuracy: Are fulfillment errors costing you time, money and customer trust?

Smarter storage, faster fulfillment

Fortunately, there are proven, cost-effective methods to overcome industry hurdles without needing to break ground on a new facility. Solutions like automated storage and retrieval systems (AS/RS) can optimize your capacity, reduce reliance on labor, lower operational costs and increase your throughput without expanding your facility footprint.

What is an AS/RS solution? An AS/RS solution optimizes storage and inventory by consolidating and condensing storage space while automating the process of storing and retrieving inventory, allowing items to be picked or routed for orders from a centralized location. Parts get sent to a goods-to-person (GTP) station, where a worker selects items from each carton or tote delivered through automated processes, chooses the appropriate item for the order and directs it to a palletizing or packing area.

Key benefits include:

  • Increased storage density
  • Higher order accuracy
  • Reduced labor costs
  • Lower operational risk
  • Faster fulfillment and replenishment

Types of AS/RS solutions

AS/RS solutions are available in various sizes and types, tailored to meet the specific requirements of product mix, capacity and throughput. Below are several types of AS/RS solutions.

High-density storage
Designed to maximize inventory storage and control within nearly any footprint, it is ideal for companies with a high number of SKUs and limited space.

Robotic picking
By utilizing automated guided vehicles (AGVs) and autonomous mobile robots (AMRs), mobile warehouse robots can transport racks of items to GTP stations, enabling a worker to pick the items for the order.

Robotic shuttle
Robotic shuttles navigate through a racking system to retrieve totes or bins and deliver them to a GTP station. Shuttles can be employed in operations that handle a diverse range of products varying in size and weight.

Unit-load
Designed for storing and handling large items on pallets or in large containers, it can utilize cranes or heavy-duty shuttles to move these items to a processing or shipping area.
