A Warehouse Management System (WMS) helps manage inventory, orders, picking, packing, and shipping inside a warehouse. Small businesses usually start with spreadsheets or basic inventory tools, but there are clear points where a WMS becomes necessary. If you recognise any of the following, then it is a sign that your business could benefit from a chat with our WMS experts at THINK.

  1. Inventory errors are becoming more common
  2. Order volume is growing quickly
  3. You’re managing more than one storage location
  4. Fulfillment is taking too long
  5. Returns and exchanges are hard to track
  6. You’re selling on multiple channels
  7. You need better operational data

If you find yourself identifying with any of those points, please read on for more information.

Inventory Errors

If you frequently experience stockouts of items that should be available, overstocking slow-moving products or mismatches between system inventory and physical stock, it means manual tracking is breaking down. The THINK WMS provides real-time inventory visibility which reduces errors and improves accuracy.

Order Volume

When a business moves from 10–30 orders per day to 100+ orders per day, manual processes become inefficient. Signs include staff spending too long locating products, orders shipping late and increased picking mistakes. The THINK WMS optimises pick paths, batch picking, and order prioritisation, allowing teams to handle much higher volume.

Multiple Storage Locations

Once inventory is stored in multiple rooms, different warehouse zones, multiple warehouses or third-party fulfillment centres it becomes difficult to track stock manually. The THINK WMS can be set up for bin/location tracking, ensuring that every item has a precise location.

Slow Order Fulfillment

If employees spend large portions of their time searching for products, manually updating spreadsheets or double-checking orders, then order fulfillment slows down. The THINK WMS can automate workflows such as barcode scanning, directed picking, and automated replenishment which in turn will reduce labour costs per order.

Poorly Tracked Returns and Exchanges

For ecommerce businesses, returns can create chaos without structured tracking. The THINK WMS can help restock returned inventory correctly, track return reasons, and prevent lost inventory.

Multiple Channel Selling

Businesses selling through several channels often hit inventory issues. Common channels include Amazon, Shopify, eBay, and Etsy. The THINK WMS can synchronise inventory across platforms to avoid overselling.

Operational Data Lacking

If you can’t easily answer the following questions, then a WMS from THINK will help with reporting.

  • Which SKUs move fastest?
  • Which picker is the most efficient?
  • Which products are slow-moving?
