How SKU & Courier Sorting (Valmo, Shadowfax, Delhivery) Saves 3+ Hours Daily in Warehouse Packing

Discover the warehouse packing methodology used by top e-commerce sellers. Batching by Main SKU and carrier partner cuts fulfillment errors by 90%.

The Chaos of Mixed-Batch Order Packing

When printing 200 or 500 shipping labels in their original raw sequence: - The warehouse staff has to pick a product, walk to the inventory rack, pack the order, search for the right polybag, and then repeat the process 200 times. - Different couriers arrive at different times (e.g. Shadowfax arrives at 1:00 PM, Delhivery at 3:00 PM, Valmo at 5:00 PM). If all packets are mixed up, staff spend hours digging through piles looking for the right parcels!


The 2-Tier Sorting Methodology: Main SKU + Delivery Partner

By applying automated sorting prior to printing:

Tier 1: Main SKU Grouping (Product-First Picking) All orders for **BROWN T-Shirt (Size L, XL, M)** come out consecutively. Your packing team picks 50 brown t-shirts at once and packs all 50 in a single assembly line without constantly walking back and forth to racks.

Tier 2: Courier Partner Separation (Dispatch-Ready Bags) Within those 50 brown t-shirts, all **Valmo** parcels are together, followed by **Shadowfax**, followed by **Delhivery**. The packed orders immediately drop into designated courier dispatch bags.


Quantifiable Efficiency Gains - **Picking Time Reduced**: 65% faster inventory collection with consolidated SKU picklists. - **Dispatch Handover**: Under 5 minutes when the delivery pickup executive arrives, with zero missing packets. - **Wrong Item Dispatches**: Dropped by over 90% because pack stations work on a single product type at a time.
