Whether you are launching on Walmart Marketplace with 200 orders a month or running an enterprise Walmart seller account at 200,000+ orders a month, the same operations team and infrastructure scales with you. Surge capacity for Rollback events, Walmart+ Weekend, Cyber Monday, and Q4 holiday peak — without your TwoDay badge or seller performance scorecard dropping.

Walmart sellers also selling on Amazon, Shopify, TikTok Shop, or wholesale who need one unified inventory pool across every channel — not separate fulfillment accounts and a daily oversell crisis when the same unit sells on Walmart and Amazon simultaneously.
Overseas brands launching on Walmart Marketplace or Walmart Connect who need American warehousing 8 miles from the Port of LA, container drayage handled directly, 2-day domestic delivery coverage, and a 3PL that can also handle Shopify DTC, Amazon, and TikTok Shop from the same Walmart inventory.
Beauty, supplement, food, baby, and toy brands selling on Walmart who need FDA-registered facility handling, MoCRA-compliant lot tracking, CPSIA-compliant labeling, or CPSC handling alongside Walmart prep — all from one LA facility with the certification stack to back it up.
A Walmart 3PL (third-party logistics provider) is a company that stores your inventory, picks and packs your Walmart Marketplace orders, and ships them — fully integrated with Walmart Seller Center via direct API connection. When a customer buys on Walmart.com, your 3PL receives the order automatically through real-time API sync, picks the items using scan-verified workflows, packs them to Walmart's shipping standards, generates the shipping label using TwoDay-eligible carriers, and dispatches the package same-day. Valid tracking uploads to Walmart Seller Center within minutes. The customer receives the shipment within 1-2 days for West Coast addresses and 2 business days for delivery to 96% of the United States via ground shipping from Los Angeles.
3PLCity is one of those partners — built specifically for Walmart sellers running Marketplace fulfillment, Walmart Fulfillment Services (WFS), Drop Ship Vendor (DSV) routing through Walmart Connect, or hybrid combinations of all three. Direct Walmart Seller Center API integration, TwoDay badge-eligible shipping from LA, same-day ship cutoff at 2 PM PST, and 96% of the US reachable in 2 business days via ground. No middleware platforms, no developer setup, no monthly software fees on top of fulfillment cost.
Most Walmart sellers start by self-fulfilling — from a garage, spare room, or small warehouse. It works until it doesn't. The right time to move to a Walmart 3PL is different for every brand, but the signals are consistent: you've lost or are about to lose your TwoDay badge because your ship-from location can't reach the East Coast in 2 days; your Walmart on-time shipment rate or valid tracking rate is dropping; you're getting chargebacks from DSV orders for missed ASN deadlines or routing guide violations; you've been accepted into WFS but can't manage the prep volume yourself; you're spending more than 10 hours per week packing and shipping Walmart orders; you're expanding to Amazon, Shopify, TikTok Shop, or wholesale and need one unified inventory pool; you're entering the United States from overseas and need American warehousing infrastructure; or your Walmart shipping costs feel too high and you have no leverage to negotiate carrier rates directly.
3PLCity supports Walmart sellers from 200 orders a month all the way to 200,000+ orders a month with the same operations team and infrastructure.
We connect through direct Walmart Seller Center API integration — not through middleware platforms like ShipStation or ShipHero that charge $50-300/month and add a layer of integration failure between Walmart and your warehouse. Setup typically takes 30 minutes. Once connected, all Walmart Marketplace orders, inventory levels, and valid tracking numbers sync in real time. WFS prep shipments and DSV routing handled through the same connection.
Yes — and the LA location is actually one of the strongest geographic positions for TwoDay badge eligibility. From our Los Angeles facility, 96% of the United States population is reachable in 2 business days via ground shipping. Combined with our same-day ship cutoff at 2 PM PST, multi-carrier rate shopping that prioritizes TwoDay-capable carriers, and 99.8% pick accuracy, the operational standards required to maintain TwoDay badge eligibility are baked into our standard workflow — not premium add-on services.
Yes. We handle full WFS prep including item labeling, polybagging, bubble wrapping, set creation, expiration date labeling, and case packing per Walmart's current WFS Inbound Requirements. Direct inbound shipping to WFS fulfillment centers from our LA facility. For hybrid sellers running both WFS and Marketplace inventory, we support seamless inventory transfer between WFS and our facility — letting you flex inventory between the two strategies based on which products perform best in each.
We maintain a routing guide compliance library for Walmart Connect DSV orders and handle every step of the DSV workflow: ASN (EDI 856) transmission ahead of Walmart's deadlines, GS1-128 carton labeling, SSCC pallet labels, BOL creation, appointment scheduling, and palletization per Walmart specification. The goal is zero chargebacks. When chargeback risks do appear, we provide documentation (photographs, scan records, BOL copies) to support disputes and resolutions.
