The order management system that never says
"we don't support that."
130+ marketplaces, carts, and EDI retailers on one stock pool. Published pricing, no sales call. Most integrations connect in days. And if the channel you need isn't built yet — we build it, at no extra cost, on Growth plans.
Three ways in, one system underneath
Brands & Sellers
Selling across Amazon, Shopify, Walmart, eBay, and dozens more without a dedicated ops team. One dashboard replaces the spreadsheet-and-browser-tab juggling most sellers start with.
3PLs & Warehouses
Managing inventory, orders, and shipping across multiple client brands and their channels from a single warehouse operation, without standing up a separate system for every account.
Enterprise & ERP Teams
Connecting NetSuite or another ERP to real-time marketplace and EDI data, so the back office and the storefronts stay in sync without manual reconciliation.
130+ integrations — here's a sample of what that means
Marketplaces
Amazon (Seller Central, Vendor Central, FBA, Multi-Channel Fulfillment), Walmart Marketplace, Wayfair, TikTok Shop, Temu, and dozens more.
Carts & ERP
Shopify as the DTC home base, plus NetSuite and other ERPs for back-office and accounting sync on Growth plans.
Shipping & Fulfillment
100+ carriers including UPS, FedEx, DHL, and USPS, plus 3PL and warehouse management system connections.
Orders pull in automatically about every 15 minutes; inventory syncs in real time across every connected channel so you don't oversell. See the full integration directory →

Four steps, not a quarter-long project
Connect what exists
Link your current marketplaces, carts, and EDI retailers — most existing integrations are live within days.
Map SKUs once
One mapping pass ties every channel's listing back to a single source of truth for stock and pricing.
Let the stock pool take over
From that point on, every sale, shipment, or return updates all connected channels automatically — no manual rekeying.
Missing a channel? It's queued
Tell us what's not on the list. On Growth plans, it goes into the build queue at no additional development cost.
Three problems that send people looking for something else
The fix: one stock pool updates every channel the moment anything sells, ships, or arrives — including FBA and 3PL-held inventory.
The fix: orders from every marketplace, EDI retailer, and your store flow into one queue and out to the right warehouse automatically.
The fix: the InfiPlex Bridge turns EDI trading-partner requirements into a standard API connection, so you serve EDI retailers without running EDI infrastructure yourself.
Most OMS platforms hide the number. Ours is right here.
Every tier includes unlimited connections to 130+ marketplaces, carts, and EDI retailers. Full plan details →
See exactly what changes, by name
Your first hundred orders. Or a hundred million syncs.
InfiPlex runs the same platform for every client on it, from operations shipping their first hundred orders to clients syncing 100M+ inventory changes a month. Nobody outgrows it, and nobody is too early for it.
Three different clients. Three real volumes. One platform.
One account keeping counts accurate across its channels and warehouses, around the clock.
Marketplaces, carts, and EDI retailers flowing through one order queue and multiple warehouses.
Same platform as the two clients above, at every plan level, so growing never means migrating.
How one platform stretches that far
Scale on InfiPlex is configuration, not migration. The same six capabilities carry an account from its first order to its hundred-millionth sync, used lightly at first and heavily later.
Individual InfiPlex clients sync more than 100,000,000 inventory changes per month and ship more than 30,000 orders per month, on the same platform new clients join at $49.99 per month with pricing published in full.
Scale questions, answered
Yes. Individual InfiPlex clients sync more than 100 million inventory changes a month, a sustained rate of about 38 updates per second, with API calls batched and paced per marketplace so every channel stays inside its rate limits.
No. Plenty of clients start around 100 orders a month on published pricing from $49.99 a month, with no implementation fees on standard connections, and grow from there on the same platform.
No. Scale on InfiPlex is configuration rather than migration: multi-warehouse routing, per-channel inventory buffers, batch operations, generated EDI documents, and a REST API are on every account from day one, used lightly at first and heavily later.

Stephanie F., Owner · Warehousing · via CapterraThe questions sellers actually ask
What makes InfiPlex different from other order management systems?
Published pricing with no sales call, most integrations connecting in days rather than months, and any missing marketplace connection built at no additional development cost on Growth plans — two builds a year on Growth Starter, four on Growth Pro.
How much does InfiPlex cost?
Basic Starter is $49.99/mo with no included orders. Growth Starter is $499.99/mo with 1,000 orders included. Growth Pro is $999.99/mo with 10,000 orders included and free new marketplace integrations. All tiers include unlimited connections to 130+ marketplaces, carts, and EDI retailers.
What happens if InfiPlex doesn't support a channel I need?
Tell us what you need. On Growth plans, it goes into our programming queue and gets built at no additional development cost — not quoted as custom work.
How long does onboarding take?
Most existing integrations connect in days: link your channels, map SKUs once, set routing rules — inventory starts self-correcting across every channel from there.
Is support based in the US?
Yes — support and programming are both US-based, and InfiPlex is an approved app on the Amazon Selling Partner Appstore, an AWS Select Technology Partner, and a Walmart, Wayfair, and Shopify integration partner.
Does InfiPlex connect to an ERP or accounting system?
Yes — Growth Pro and Growth Enterprise plans include ERP connections such as NetSuite, keeping back-office records in sync with real-time marketplace and EDI data.
Is InfiPlex a good fit for a 3PL managing multiple client brands?
Yes — InfiPlex is used by 3PLs and warehouse operators to manage inventory, orders, and shipping across multiple client brands from a single system rather than separate tooling per account.
Is there a free trial?
Basic Starter has no long-term commitment, so you can start and stop as needed. Growth plans require a 3-month commitment. Check the current pricing page for any trial terms in effect.
What's the cancellation policy?
Basic Starter is month-to-month with no annual lock-in. Growth Starter and Growth Pro require a 3-month commitment; the 3PL Warehouse Connector and Growth Enterprise require 12 months.
Does InfiPlex handle customer returns?
Returns and restocks update the same central stock pool as sales and shipments, so inventory reflects a return the moment it's processed across every connected channel.
Every channel you sell on. Every channel you will.
Connect what exists today. Queue what doesn't.
