Inventory chaos, stopped

Disconnected systems and manual processes don't just slow you down — they create compounding errors across every channel you sell on. Cart.com's OMS and inventory management platform are built to close the gap.

The problem

No single source of truth causes oversells and stockouts
Manual routing to fulfillment locations is slow and doesn't scale
Inventory lags sales, so one channel oversells while stock sits idle
Reactive replenishment makes stockouts a customer problem
Disconnected OMS and 3PL create gaps where errors hide

Top 20 in Kids Multivitamin

Plus a spot on Amazon's Mother's Day gift list — within months of launch.

When you achieve that growth, maintaining inventory is the hardest part. The Amazon ecosystem is dependent on you maintaining inventory – and you’re penalized if you don’t. It’s critical to maintain inventory and scale our capacity, while maintaining quality, to meet the surging demand.

Months to a Sephora deal

Hanni landed an exclusive wholesale agreement with Sephora just 8 months post-launch, then outgrew their 3PL's capacity to keep up.

Our business grew very quickly, both our DTC and Wholesale. That became unmanageable for our previous 3PL.

Software and fulfillment that work as one system

Most OMS vendors sell you software and leave integration with your 3PL as your problem.

Cart.com is different: our inventory and order management platform is natively connected to our fulfillment network. That means inventory data from our warehouses flows directly into your OMS in real time: no middleware, no lag, no reconciliation headaches.

When you route an order through Cart.com's system, it's not just a software decision; it's a warehouse pick-and-pack instruction that executes automatically.

This closed-loop connection between software and physical operations is what lets Cart.com customers achieve results like Underwear Expert's 99.9% inventory accuracy and 99% same-day shipping for B2C orders, results disconnected systems simply can't match.

Fulfillment software

Powered by AI,
built for real operations

Cart.com combines real-time data with AI-driven intelligence to help brands make smarter inventory and fulfillment decisions — before problems occur, not after.

AI Demand Forecasting

Our AI analyzes historical sales and real-time signals to forecast demand by SKU and location, so you avoid overstock and stockouts on your best sellers.

Dynamic Pricing Optimization

Our pricing tools monitor market and competitor pricing in real time and adjust your prices within the guardrails you set, maximizing revenue while staying competitive.

Business Intelligence and Reporting

Hundreds of pre-built reports on order performance, inventory, and profitability, drillable from SKU level to enterprise trends, all from one dashboard.

Proactive Alerts and Automation

Configure rule-based alerts for low stock, cancellation spikes, routing exceptions, and SLA risk, so issues surface before they hit customers.

6-pre-purchase-accurate-inventory-everywhere

Pre-purchase: accurate inventory, everywhere you sell

Inventory accuracy starts before the order is placed. Cart.com keeps stock levels synchronized across every channel in real time — so customers see accurate availability on your DTC site, Amazon listing, and Walmart storefront simultaneously.

When inventory drops below your defined thresholds, the system automatically suppresses listings and triggers replenishment workflows. The result is fewer canceled orders, better marketplace seller ratings, and customers who trust what they see.

It's the foundation that makes everything else in your order lifecycle work correctly.

At purchase: intelligent routing and order orchestration

The moment an order is placed, Cart.com's OMS goes to work. Routing logic evaluates every available fulfillment location — considering inventory position, shipping zone, carrier rates, and delivery promise — then automatically directs the order to the optimal facility.

Orders can be split across locations, consolidated, or prioritized based on rules you define. For BOPIS and ship-from-store scenarios, the same orchestration engine manages store-level inventory reservations and fulfillment workflows.

Every routing decision is logged and traceable, giving your operations team full visibility into why each order went where it did.

Post-purchase: visibility, returns, and customer service

Once an order ships, Cart.com keeps both your team and your customers informed. Real-time tracking data flows from the warehouse through the OMS and out to your customer-facing touchpoints, reducing "where is my order" contacts and improving satisfaction scores.

When returns happen, Cart.com's reverse logistics workflow captures condition data, routes items to the right disposition path, and updates inventory automatically.

Your customer service team gets the tools to modify orders, change shipping methods, reroute packages, and issue resolutions — all without leaving the platform.

Explore the full Cart.com fulfillment platform

Inventory and order management is the operational core — but Cart.com's platform extends across every layer of your fulfillment operation.

Omnichannel Fulfillment

Ship to any channel — DTC, retail, wholesale, or marketplace — from a single network of Cart.com fulfillment centers. Our omnichannel 3PL services are designed for brands that need one partner to handle everything, not a different vendor for every channel. From B2C parcels to B2B pallets, we've got the infrastructure and expertise to scale with you.

Warehouse Management Software (WMS)

Built for scalability, it transforms fulfillment facilities into high-performance operations that minimize errors and maximize throughput. Fully integrated with the OMS for a seamless software-to-warehouse connection.

Transportation Management System (TMS)

Marketplace Management

Manage product listings, inventory, and orders across Amazon, Walmart, Target Plus, and other leading marketplaces from a single platform. Cart.com's marketplace management tools keep your catalog, pricing, and inventory synchronized so you can grow your marketplace presence without growing your operational headcount.
