Fulfillment Platform Integrations Built for Global Ecommerce Brands
Your tech stack should disappear into the background. Brands working with Lite Fulfillment don't want another dashboard — they want orders from Shopify, Amazon, Walmart, TikTok Shop, and every other channel to land in our warehouse, ship the same day, and reach buyers across 200+ countries without a single CSV upload. That's what our fulfillment platform integrations deliver.
Whether you sell on one Shopify store or six marketplaces at once, our 3PL software integrations keep orders, inventory, and tracking in sync across every channel in real time — no CSV uploads, no oversells, no firefighting.
An e-commerce integration is the live connection between your sales channel and your 3PL's warehouse management system. When it's working, your store and our warehouse share a single source of truth: one inventory count, one order queue, one tracking record. When it's broken — or built on nightly CSV exports — you oversell SKUs, ship the wrong items, and lose buyer trust.
Lite Fulfillment maintains native, API-level integrations with every major DTC and marketplace platform. No middleware tax, no spreadsheet workarounds, no we'll sync at midnight. Orders flow in within seconds, inventory updates push out within seconds, and your brand looks effortless to every buyer.
How a Lite Fulfillment Integration Goes Live
Five stages, most of which happen automatically once your store is connected.
Connect Your Store
Authorize Lite Fulfillment inside Shopify, Amazon Seller Central, Walmart, WooCommerce, eBay, Etsy, or TikTok Shop. Most integrations take under 10 minutes.
Sync Products & Inventory
We pull your SKU catalog, map it to inventory in our Delaware warehouse, and surface live stock counts back to every connected channel.
Orders Flow In Automatically
New orders land in our system within seconds. No CSV uploads, no manual exports — your team keeps working in the store you already use.
We Pick, Pack & Ship
Same-day dispatch on orders received before cutoff, 1–2 day US ground, and worldwide routing to 200+ countries via DHL, FedEx, UPS, and USPS.
Tracking Pushed Back
Carrier tracking, delivery status, and return events sync back to each channel so your buyer notifications fire automatically.

What's Included in Every Integration
No middleware tax. No spreadsheet workarounds. Every connection is native and maintained in-house.
Real-Time Order Sync
Orders pull into our WMS via webhook the moment a buyer checks out. There's no polling delay, no batched imports — just a live order queue our pick teams work from all day.
Two-Way Inventory Updates
Every receipt, every pick, every return adjusts the inventory count we push back to your store. Multi-channel sellers get a single inventory pool that updates simultaneously on Shopify, Amazon, Walmart, and any other connected channel — ending oversells across listings.
Automated Tracking & Buyer Notifications
Carrier tracking numbers from DHL, FedEx, UPS, and USPS push back to each channel automatically. Your buyer notification emails, post-purchase apps, and Amazon Seller Central handling-time metrics all stay green.
Returns Visibility
When a return is created in your store, it appears in our queue with the original order context. We inspect, grade, and disposition the item, then push the outcome back to your platform.
Returns Management Services →Custom & Headless Support
Running a headless storefront, a custom OMS, or an ERP-driven operation? Our REST API and webhook framework support bespoke connections — we've onboarded brands running Sanity, Contentful, and custom Laravel stacks without disruption.
Who These Integrations Are Built For
We are specific about the brands and operations we connect with — because fit matters in an integration relationship.
Multi-channel DTC brands selling on Shopify Plus, one or more marketplaces, that are tired of inventory drift
Amazon sellers running FBA and FBM in parallel and needing a prep partner whose system talks to Seller Central directly
International brands shipping from the US to West Africa, South America, Brazil, the UK, EU, Middle East, and Asia who want one integration to cover both domestic and global fulfillment
Subscription & kitting operators needing custom assembly tied to channel-specific orders
High-velocity TikTok Shop & creator-led brands where a viral moment can mean 10x order volume overnight without warning
Why Brands Consolidate on Lite Fulfillment's Integrations
Most 3PLs either treat integrations as a billable add-on or rely on third-party connectors, which introduce sync delays. We treat them as core infrastructure. Every connection is maintained in-house by our operations team, monitored continuously, and updated whenever a platform changes its API. That's how we keep 99.98% order accuracy across 500+ brands shipping to 200+ countries — the integration layer doesn't drop the ball, so the warehouse doesn't either.
And because our warehouse is in Delaware — a 0% sales tax state 18 miles from Amazon's East Coast fulfillment center — our integration with Amazon FBA gives sellers an inbound cost advantage no inland prep center can match.
"We were juggling Shopify, Amazon FBM, and TikTok Shop manually. Lite Fulfillment hooked into all three in a day, and now our inventory never goes out of sync. That alone is worth it."— DTC Brand Owner, Multi-Channel Apparel Seller
