In the building materials industry, dealing with damaged or returned inventory is a regular part of business. But for high-volume distributors, poor handling of these materials can lead to inventory shrinkage, lost revenue, and unhappy customers.
The good news? When done right, tracking damaged and returned items can actually improve your inventory accuracy, strengthen vendor relationships, and optimize warehouse space. Let’s explore advanced strategies to help your team manage this process like pros.
Materials such as lumber, piping, insulation, or fasteners can be returned or reported as damaged for a variety of reasons:
If these items aren’t tracked accurately or processed quickly, they clutter warehouse space, confuse inventory levels, and reduce available stock for sale. Worse yet, damaged materials mixed with sellable stock can result in failed deliveries or rejected orders.
Establish a clearly labeled and physically separate area for returns and damaged goods. This prevents them from getting mixed back into active inventory and ensures quick visibility during audits or cycle counts.
Tip: Color-coded signage and bins help your team instantly identify non-sellable stock.
The moment an item is identified as damaged or returned, scan it into your ERP system with a unique return code. Include details such as:
This real-time data prevents manual entry errors and makes returns trackable by SKU, location, and time.
Use your ERP to build a return material authorization (RMA) process that includes automatic routing for approvals, inspections, and actions. For example:
This not only speeds up decision-making but also ensures accountability.
Designate a team member or small team responsible for managing returns. Their duties can include:
Having dedicated oversight reduces the chances of returns getting lost or mismanaged.
Attach photos and notes to damaged items within your ERP system. This is especially helpful when:
Some ERP systems offer mobile apps where staff can snap photos and upload directly from the warehouse floor.
Are certain SKUs being returned more often?
Are returns higher from a specific vendor or customer?
Is one yard location experiencing more handling damage?
These insights help you take preventive action, improve vendor agreements, or invest in better packaging and racking.
Returned items that are still sellable should be processed back into inventory as quickly as possible. Meanwhile, scrap or unusable items should be written off to keep stock levels accurate. Automate this within your ERP to reduce delays and mistakes.
Don’t let damaged stock pile up. Use timers or reminders in your system to ensure that each item in the return zone is reviewed and processed within a set number of days (e.g., 5 business days).
Many returns are preventable. Offer regular training on proper handling of delicate or oversized building materials, including:
If your analysis shows repeat quality issues from a supplier, schedule quarterly reviews and share return data with them. This can lead to:
Efficiently tracking and managing damaged and returned materials isn’t just about cleanup—it’s a critical part of smart warehouse and inventory management. With the right workflows, tech tools, and team mindset, you can turn what was once a hassle into a data-driven advantage.
By taking control of your returns process, you not only preserve warehouse space and inventory accuracy but also create better accountability across your supply chain.

Warehouse Design Considerations for FIFO vs LIFO Inventory Strategies for Construction Supply
Choosing between FIFO (First-In, First-Out) and LIFO (Last-In, First-Out) inventory strategies doesn’t just impact accounting—it significantly influences how your warehouse should be designed, especially in the construction supply industry.
With bulky, heavy, and often shelf-life-sensitive materials like lumber, piping, fasteners, and chemical-based products, your layout can either support or sabotage your inventory goals. Here’s how to align your warehouse design with the right strategy for maximum efficiency.
In this strategy, the materials that enter your warehouse first are the first ones to be picked and shipped out. FIFO is especially useful for:
Inventory that’s prone to degradation over time (e.g., treated lumber, moisture-sensitive goods)
LIFO means newer materials are picked and shipped first. It’s more common in bulk distribution or when the age of the inventory doesn’t affect its usability or value. LIFO can be helpful for:
FIFO: Requires “flow-through” shelving or pallet flow racks. Materials are loaded on one side and picked from the opposite side to ensure the oldest stock gets used first.
LIFO: Uses “drive-in” or “push-back” racks where the most recent stock is most accessible from the front.
Design Tip: For FIFO, ensure clear, uninterrupted access paths to the oldest stock. For LIFO, high-density racking systems that prioritize storage capacity may be more efficient.
Your picking routes should match your inventory flow strategy.
FIFO: Design picking paths that loop through zones based on aging inventory, prioritizing earlier stock.
LIFO: Picking zones can be more linear or stacked, since age isn’t a concern.
Design Tip: Use signage or digital pick systems to guide warehouse operators through the most efficient route based on the inventory logic.
FIFO: Requires separate receiving and shipping docks or clearly divided staging zones to avoid cross-contamination of old and new inventory.
LIFO: Can use shared dock areas if proper tracking is in place.
Design Tip: In FIFO layouts, keep new arrivals away from outgoing staging areas to avoid confusion.
FIFO relies heavily on visibility and labeling to identify aging inventory.
LIFO requires less detailed tracking by date but benefits from SKU-based organization.
Design Tip: Invest in clear barcode labels, RFID tags, and digital dashboards that show inventory age in real-time to support FIFO workflows.
FIFO may need more floor space for organized aging lanes or zones by material type.
LIFO can stack products deeper, maximizing vertical and horizontal space.
Design Tip: For FIFO, consider using vertical shelving only if the materials can be safely accessed without compromising rotation principles.
Your ERP software must support the inventory logic you’ve chosen.
For FIFO, make sure the system can sort pick lists by lot date or receiving date.
For LIFO, ensure your system always pulls the latest receipt by default unless overridden.
Design Tip: Link warehouse layouts within your ERP/WMS to automate picking routes and reduce human error in FIFO environments.

Warehouse layout isn’t one-size-fits-all. By aligning your storage design, pick paths, racking, and ERP system with your chosen inventory strategy—FIFO or LIFO—you build a warehouse that supports both operational efficiency and material integrity.
In construction supply, where product condition and fast fulfillment matter, a well-planned layout based on your inventory strategy can give you the competitive edge.
