Chewy 3PL That Won't Get You Chargebacked

Chewy.com is the largest online pet retailer in the United States, serving millions of pet parents with food, treats, toys, medications, and supplies. For pet brands, selling on Chewy opens access to a massive, loyal customer base — but it also comes with strict fulfillment requirements that can trip up unprepared vendors.

Unlike marketplaces where you simply ship when you want, Chewy operates a curated vendor program with specific compliance standards. Vendors must integrate via EDI, follow detailed routing guides, meet tight delivery windows, and maintain near-perfect accuracy. Miss these standards and you'll face chargebacks that eat into your margins — or worse, risk losing your Chewy vendor status entirely.

This is where a Chewy 3PL becomes essential. A third-party logistics provider experienced with Chewy handles the operational complexity so you can focus on product development, marketing, and growing your pet brand. The right 3PL partner understands Chewy's requirements intimately and has systems built specifically for compliance.

How Chewy B2B Wholesale Fulfillment Works

In the B2B wholesale model, Chewy places purchase orders for inventory they'll stock in their own distribution centers. You (or your 3PL) pick and ship cases or pallets to Chewy's warehouses. Chewy then handles fulfillment to end customers. This model works best for high-velocity SKUs where Chewy wants inventory on hand for fast shipping.

Orders flow through Chewy's DSCO/Rithum platform via EDI (Electronic Data Interchange). This isn't optional — Chewy requires automated order processing. Manual order entry isn't supported at scale.

Chewy EDI Requirements: What You Need to Know

EDI is the backbone of Chewy vendor operations. Chewy uses the Rithum platform (formerly DSCO) to manage vendor EDI connections. The key transaction types you'll handle include:

Setting up EDI isn't trivial — it requires technical integration between your systems (or your 3PL's WMS) and Rithum. This is why working with a Chewy-experienced 3PL matters: we've already built and tested these integrations.

Chewy Routing Guide Compliance

Chewy's routing guide specifies exactly how shipments must be prepared and sent:

• Approved Carriers: Chewy specifies which carriers you can use (typically FedEx, UPS) and which service levels are required.
• Delivery Windows: Wholesale shipments have appointment windows at Chewy DCs.
• Carton Specifications: Maximum weights (typically 50-70 lbs for small parcel), dimension limits, and how products must be packed.
• Labeling Requirements: Chewy order IDs must appear on cartons. Specific label placements and formats are required.

Routing guide violations are the leading cause of Chewy chargebacks. A 3PL that understands these requirements builds compliance into every step — from carrier selection to label printing to pre-shipment validation.

Understanding Chewy Chargebacks

Chargebacks are financial penalties Chewy deducts from your payments when you fail to meet compliance requirements. They typically range from $25-$500 per incident. Common triggers include:

• Late Shipments: Orders not shipped within the required window.
• ASN Errors: Missing, late, or incorrect advance ship notices.
• Routing Guide Violations: Wrong carrier, wrong service level, overweight cartons, incorrect labeling.
• Invoice Discrepancies: Quantities or pricing don't match the PO.

The best way to avoid chargebacks is prevention through systematic processes. Every order should go through compliance checks before shipping. This is exactly what we build into our Chewy fulfillment workflow.
