Consumer packaged goods (CPG) brands face one of the most complex fulfillment challenges in eCommerce: selling the exact same product through radically different channels simultaneously, each with its own requirements, documentation, and packaging specifications.**The Omnichannel CPG Challenge**A CPG brand might be selling the same product through: their own DTC website via Shopify, Amazon FBM and FBA simultaneously, Walmart Marketplace, Target or Whole Foods wholesale, and regional grocery through a distributor.Each channel has different requirements. DTC wants fast shipping and branded packaging. Amazon wants FNSKU labels and FBA-compliant cases. Target wants EDI and routing guide compliance. Whole Foods wants floor-ready displays and GS1-128 case labels.Without a 3PL that handles all of these from one inventory, you are either managing multiple warehouses or making costly compromises on one channel to serve another.**GS1 and Barcode Compliance**Retail-bound CPG products need properly registered UPC or EAN barcodes through GS1. For wholesale and retail accounts, case-level GS1-128 barcodes and pallet-level SSCC labels are required for EDI ASN submission.3PLCity manages all of this. We apply GS1-128 case labels, generate SSCC pallet labels, and submit EDI ASNs for all EDI-enabled retail accounts.**High-Volume Throughput**CPG brands ship volume. Thousands of units per day is not unusual. Our operations are built for high throughput — multiple carrier pickups daily, streamlined receiving processes, and dedicated CPG fulfillment workflows.**One Inventory, All Channels**The most important thing a CPG 3PL provides is unified inventory across all channels. When we pick a unit for a DTC order, it disappears from the Amazon available count, the Walmart listing, and the wholesale allocation — simultaneously, in real time.
