When wholesale inventory issues start to hurt your business

For growing ecommerce brands, wholesale inventory problems often surface when stockouts or overselling start affecting order fulfillment. Missing SKUs can create customer dissatisfaction, late shipments, and costly chargebacks. Without consistent counts and real-time visibility, your operations become reactive rather than proactive.

Brands with recurring stockouts or inaccurate reorder points notice slowed growth and strained partnerships with B2B customers. This is when investing in a robust inventory management framework and partnering with a competent 3PL becomes critical.

Story: How BrandX improved operations with a 3PL

Before

BrandX, a health supplement brand, managed wholesale inventory across multiple warehouses with spreadsheets. They struggled with backorders and stock discrepancies, which delayed shipments and frustrated wholesale partners.

Pain points

  • Overstocking on some SKUs and stockouts on others
  • Manual order tracking created errors and inefficiencies
  • Inability to forecast demand accurately across seasonal trends

The shift

After integrating with PFS, BrandX centralized inventory, automated reorder alerts, and gained real-time visibility across all SKUs. They cut stockouts, reduced operational errors, and improved delivery accuracy, leading to higher partner satisfaction and repeat business.

Key practices for efficient wholesale inventory management

  • Conduct regular SKU-level counts to maintain stock accuracy.
  • Define reorder points and optimal order quantities per product.
  • Document and track every inbound shipment from manufacturers.
  • Perform periodic audits to validate system data against physical inventory.
  • Segment SKUs by demand velocity to prioritize replenishment.
  • Maintain clear communication between sales, warehouse, and fulfillment teams.

Choosing the right inventory management system

A modern IMS helps consolidate multichannel wholesale operations. Key features to look for include real-time inventory tracking, automatic reorder notifications, multichannel integration, and forecasting tools. A strong 3PL partner like PFS enhances these capabilities by providing centralized fulfillment, kitting, and detailed reporting.

Leveraging data to forecast demand and replenish stock

Accurate demand forecasting requires historical sales data, seasonal patterns, and SKU-level turnover rates. By analyzing trends, brands can plan procurement in advance, reduce stockouts, and avoid unnecessary inventory holding costs. Automating these insights ensures timely reorders and consistent availability for B2B customers.

Centralizing multichannel order visibility

Multichannel sales amplify the need for synchronized inventory information. Centralizing order data ensures that all channels pull from the same stock levels, preventing overselling and missed shipments. Real-time dashboards and reporting help operations teams make informed decisions and maintain fulfillment SLAs.

Automation for accuracy and efficiency

Automation reduces manual errors and saves time. IMS features such as automatic stock adjustments, integrated reorder alerts, and synchronized multichannel updates ensure inventory is always accurate. Combined with PFS’s fulfillment services, automation enables consistent order fulfillment, improved operational efficiency, and fewer chargebacks.
