OC3PL does not publish rate cards. It quotes pricing built around your SKUs, order volumes and workflows, and describes transparent line-item billing with no setup fees and no hidden minimums. What you pay depends on how much you store, how many items go into each order, and which extras such as kitting or Amazon prep you use. Ask for a custom quote with every line item spelled out.
For Amazon FBA prep, you can use your preferred carriers or Amazon-partnered shipping options, and OC3PL coordinates outbound prep and forwarding around your routing requirements. For standard ecommerce orders, rate shopping runs across a multi-carrier setup at negotiated rates. If keeping your carrier contracts matters, raise it during onboarding so the routing rules are built that way from the start.
Yes. OC3PL supports brands shipping tens of thousands and often more than 100,000 orders per month, across more than 500,000 square feet of warehouse space in its network, with automated and robotics-enabled workflows, cross-docking and bulk pallet storage. High SKU count catalogs, wholesale distribution and Amazon overflow storage are all handled. Ask for capacity detail that matches your own peak.
FBA prep is the work of getting inventory into Amazon's network in the condition Amazon requires: correct FNSKU labels, compliant poly bagging, carton and pallet labeling, and routing. Getting it wrong can mean rejected shipments, non-compliance fees or lost selling time while a product sits out of stock. Outsourcing FBA prep hands that work to a team that already runs it as a standardized workflow.
FBA prep covers FNSKU labeling, poly bagging with suffocation warnings, expiration date labeling, kitting and bundling, case-packed and mixed-ASIN shipments, carton forwarding, pallet prep and labeling, barcode verification, Amazon routing compliance, and SPD and LTL shipment prep. These are the day-to-day prep tasks required for compliant FBA shipments, handled so that brands avoid inbound delays, rejected inventory and unnecessary Amazon fees as volume grows.
Most shipments are prepped and forwarded within 24 to 48 hours after inbound receiving, with timing depending on shipment size, prep complexity and inbound volume. Because the warehouse sits near Amazon receiving centers in Southern California, prepped inventory often reaches Amazon the same day or the next morning after it leaves. Ask how your specific prep mix affects that window.
Yes. OC3PL regularly processes mixed-ASIN shipments for wholesale, private label, arbitrage and bundled Amazon inventory while keeping labeling and prep workflows organized. Case-packed inventory, kitting and bundled products are supported with barcode verification and quality control checks before anything ships, so the correct labels and quantities are confirmed first. Tell your rep which ASINs travel together so the carton plan is right.
Yes. OC3PL prepares cartons, pallet labels, routing documentation and shipment configurations for both Small Parcel Delivery and Less Than Truckload FBA shipments, following Amazon's inbound requirements. Volume and location in a major logistics hub bring discounted rates on small parcel and freight, plus flexible pickup scheduling. Confirm your routing preference before the shipment plan is created in Seller Central.
Common causes are missing FNSKU labels, incorrect carton labeling, overweight boxes, missing suffocation warnings, mixed inventory errors and pallet configuration problems. Even small compliance mistakes can trigger inbound delays, chargebacks, rejected shipments or receiving problems inside Amazon fulfillment centers. Standardized workflows and quality control checks before inventory leaves the warehouse are what reduce that risk as SKU counts and shipment volume climb.
Yes. OC3PL supports both approaches. With Fulfillment by Merchant, orders placed on Amazon route from Seller Central into OC3PL's warehouse system for immediate fulfillment, which matters because Amazon's shipping deadlines affect your seller rating. With FBA, OC3PL acts as the prep center that receives, inspects, labels and forwards inventory into Amazon's network. Many brands run both at once from a single inventory pool.
OC3PL connects to Amazon Seller Central through an API rather than spreadsheet uploads. When you create an FBA shipment plan in Amazon, it is pushed automatically into OC3PL's warehouse system, which starts the internal workflow. As the shipment is received, prepped and packed into master cartons, status updates flow back into your Seller Central dashboard, and tracking updates once the shipment is handed to the carrier.
Amazon's network is heavily concentrated in Southern California, particularly the Inland Empire just east of the Orange County facility, and ONT8, LGB8 and LAX9 are receiving hubs a short truck drive away. That proximity means shipments often reach Amazon's dock the same day or the next morning, rather than the multi-day journey from a warehouse elsewhere in the country.
OC3PL supports private label brands, wholesale sellers, retail arbitrage operations, Amazon aggregators managing multiple portfolios, subscription brands with Amazon channels, and multi-channel businesses using Amazon for reach. Amazon launch programs, where prepped SKUs and on-time inbound deliveries matter most, are handled too. Workflows scale from simple FNSKU labeling to complex bundled shipments and palletized freight.
Yes. OC3PL can integrate with TikTok Shop so social commerce orders flow directly into the warehouse system for fulfillment, and TikTok Shop sits alongside Shopify, WooCommerce, BigCommerce and Amazon among the connected channels. Because newer channels change quickly, confirm the current connection method and what data syncs both ways before you build a campaign around it.
Yes. OC3PL's ecommerce fulfillment page names Shopify, Amazon, Walmart and WooCommerce among more than ninety supported platforms plus custom APIs. Its integrations directory also lists multichannel management tools such as ChannelAdvisor, Linnworks and Channel Pilot. Running several channels from one inventory pool is the point, so ask how stock gets allocated across marketplaces before you split inventory between separate systems.
Yes. Beyond Amazon, OC3PL handles retail-compliant labeling, advance shipping notice processing, GS1-compliant labels, purchase order routing per retailer and palletized shipping, and it says it follows retailer routing guides and provides weekly service level reports. Its kitting service also builds retail-ready displays that ship pre-assembled. Chargeback exposure usually comes from routing and labeling detail, so share your retailer's guide early.
The onboarding page names Recharge among the integrations set up during launch, alongside Shopify, Amazon, Klaviyo, WooCommerce and ShipStation, and one case example describes Shopify, Klaviyo and Recharge integrated with a full SKU map. OC3PL's article on choosing a subscription platform discusses Recharge, Bold and Skio as the options brands weigh. If your billing app is not listed, ask about a custom connection.
Yes. We handle FNSKU and ASIN labeling, poly bagging, bundling, carton forwarding and pallet prep, with internal quality checks before outbound forwarding. Most shipments are prepped and forwarded within 24 to 48 hours after inbound receiving, depending on shipment size and prep complexity, and mixed-ASIN shipments are routine. Our Amazon FBA prep services run alongside your direct-to-consumer fulfillment out of the same building.
Yes. You can use your preferred carriers or Amazon-partnered shipping options, and we coordinate outbound prep and forwarding around your routing requirements. We handle small parcel, less-than-truckload and palletized shipments and follow current Amazon prep requirements for labeling, bagging, bundling and carton prep. Our page on FBA prep services in California explains how the workflow stays standardized as the rules change.
Yes. We can apply special stickers and labels, add size stickers to poly bags, replace tags, and insert marketing cards, thank you notes or return instructions into orders. For Amazon inventory we apply FNSKU labels with barcode accuracy checks. These steps get written into the packing procedure for each SKU through our custom kitting and assembly service, so the thousandth order looks like the first.
