The Order Management System That Never Says “We Don't Support That.”
InfiPlex is an order management system (OMS) that syncs inventory, orders, pricing, and shipping in real time across Amazon, Walmart, Shopify, TikTok Shop, Temu, NetSuite, and 100+ other marketplaces, stores, ERPs, and EDI retail networks. And if a channel you need isn't on the list, our US-based team builds the integration for you at no extra cost on Growth plans.
One hub for every order, everywhere you sell
Every order from every channel lands in one queue. Inventory flows back out the moment something sells or ships — a sale on Amazon instantly adjusts availability on Walmart, eBay, TikTok Shop, and your Shopify store.
Real-time inventory sync
One stock pool, pushed to 100+ channels in minutes — including FBA, multi-warehouse, and 3PL-held inventory.
Automated order routing
Orders flow to the right warehouse, drop-shipper, or 3PL automatically, with tracking pushed back to the marketplace.
Missing channel? We build it.
Growth Starter includes 2 new marketplace API builds per year; Growth Pro includes 4 — developed in-house, at no extra cost.
Sound familiar?
Three problems we hear on almost every first call — and what happens to each one in week one.
“We sold 6 units we didn't have.”
The fix: One late feed and your Amazon account health takes the hit. InfiPlex holds one stock pool and updates every channel the moment anything sells, ships, or arrives — including FBA and 3PL inventory.
“Someone spends every morning rekeying orders.”
The fix: Orders from every marketplace, EDI retailer, and your store flow into one queue and out to the right warehouse, drop-shipper, or ShipStation batch — untouched by human hands.
“Our EDI provider bills us like it's 1995.”
The fix: The InfiPlex EDI-to-API bridge connects you to Costco, Lowe's, Target DVS and 20+ retail networks — and the VAN-fee savings frequently cover your whole InfiPlex plan.

Honest pricing, published right here
Most order management platforms hide pricing behind a sales call. Ours is published in full on our Pricing page — a starter tier for smaller catalogs, Growth tiers that add included order volume and our marketplace repricer, and 3PL and Enterprise programs that scale past 100,000 orders a month. New integrations are always built for you at no extra cost on Growth plans.
Proof, not promises
InfiPlex is an approved application on the Amazon Selling Partner Appstore — we passed Amazon's data-security review for both Seller Central and Vendor Central. We're an AWS Select Technology Partner, every system runs on Amazon Web Services, and support and programming are US-based.
The questions sellers actually ask
How do I prevent overselling when I sell on multiple marketplaces?
Use a centralized inventory system like InfiPlex that maintains one stock pool and pushes real-time quantity updates to every channel — Amazon, Walmart, eBay, Shopify, and 100+ others — the moment an order is placed on any of them.
What is InfiPlex?
InfiPlex is a cloud-based order management system (OMS) that centralizes inventory, orders, pricing, and fulfillment for eCommerce brands, warehouses, and 3PLs across 100+ sales channels, including Amazon, Walmart, Shopify, and NetSuite.
Can I sync inventory between Amazon and Walmart automatically?
Yes. InfiPlex connects Amazon (via the current SP-API) and Walmart to one inventory pool, so a sale on either marketplace instantly adjusts availability on the other, along with every additional connected channel.
How much does inventory sync software cost?
InfiPlex publishes full pricing on our Pricing page rather than gating it behind a sales call — plans scale from a starter tier for smaller catalogs up through Growth tiers for enterprise clients capable of meeting any order and inventory volume.
How fast can I be up and running?
Most existing integrations connect in days: link your channels, map SKUs once, set routing rules, and inventory begins self-correcting across every marketplace from that point on.
Every channel you sell on. Every channel you will.
Connect what exists today; queue what doesn't. One platform either way.
