Orders come in as purchase orders (POs) rather than individual cart checkouts, quantities ship by the case or pallet rather than the each, and freight moves by LTL or FTL rather than small parcel. The compliance requirements are entirely different from DTC, and the cost of getting it wrong is direct: retailers charge back 1–5% of invoice value for label errors, late ASNs, and routing-guide violations.
The foundation of B2B fulfillment is EDI — Electronic Data Interchange. Major retailers and distributors require structured EDI transactions for every PO (850), advance ship notice (856), and invoice (810). A 3PL without live EDI trading-partner relationships with your customers will require you to maintain those connections yourself, adding cost and a technical burden. Verify that any candidate 3PL has your specific retail trading partners already connected, not just “EDI capability.”
The second critical differentiator is routing-guide compliance. Every major retailer — Walmart, Target, Costco, Amazon Vendor, Home Depot — publishes a routing guide specifying approved carriers, delivery windows, pallet configurations, UCC-128/GS1-128 label specs, and ASN timing requirements. Failure on any point generates chargebacks that hit your revenue directly. High-performing B2B 3PLs have a dedicated compliance team that monitors routing-guide updates (they change quarterly) and maintains documentation by trading partner.
The four factors that determine whether a B2B 3PL will protect — or erode — your retail relationships.
Ask for their current EDI trading-partner list and confirm your specific retail customers are on it. New EDI connections take 4–12 weeks to test and certify — that delay at onboarding can cost you a selling season. Verify support for the full 850/856/810 transaction set, plus any retailer-specific requirements (753/754 routing, 940/945 for drop-ship, 832 price catalog). A 3PL that says “we can set up EDI for any partner” is not the same as one that has been live on that trading partner for two years.
Routing guides change. Walmart, Target, Costco, Home Depot, and Amazon Vendor all update carrier assignments, delivery window specs, and label requirements throughout the year. Ask specifically: who on their team monitors routing-guide updates? How are changes communicated internally and reflected in their WMS rules? Request their chargeback rate data by retailer for the last 12 months. A well-run B2B 3PL should be below 0.5%; anything above 2% is a red flag regardless of their other strengths.
Confirm which LTL carriers they have contracted rates with (Old Dominion, XPO, Estes, Saia, FedEx Freight are the major national carriers) and whether their freight volumes qualify for class-70–85 discounts. For FTL, ask about their load board access and brokerage relationships. A B2B 3PL with strong carrier contracts can reduce your freight cost by 20–40% vs. arranging LTL independently. Also confirm they have sufficient dock doors and scheduling capacity during your peak shipping windows.
B2B order management is more complex than DTC: POs can have line-item changes, partial receipts, backordered units, and delivery appointment requirements. Ask whether their WMS supports: partial PO shipment with ASN accuracy, PO line-item holds pending inbound inventory, and real-time PO status visible to your team without requiring email. For brands mixing B2B and DTC, ask how the WMS handles shared inventory allocation between a committed retail PO and live DTC orders — see the omnichannel 3PL guide for more on this.
Estimated fee ranges for B2B and wholesale 3PL services in 2025–2026. Actual rates vary by provider, order size, freight volume, and retailer mix.
All figures in USD. Ranges reflect typical US B2B and wholesale 3PL rates in 2025–2026. LTL freight rates are subject to carrier base rate changes and fuel surcharges, which fluctuate quarterly. EDI setup is a one-time cost per trading partner; transaction fees are ongoing per document transmitted. Chargeback costs are not included — these are assessed by retailers directly and are a reason to prioritise routing-guide compliance at provider selection.
