What We Solve
What DropStream solves for WMS integrations.
Your WMS runs the warehouse, but only if the data reaching it is right. Every client's carts, marketplaces, and ERP have to land in your WMS in the right format, sync back without drift, and handle returns and ASNs cleanly. DropStream is the layer that keeps your WMS and your merchants' channels in agreement.
Get Started
01
Orders that land in your WMS correctly
Every channel maps to the right client account, SKU, and ship method in your WMS format, so the warehouse executes without manual cleanup.
02
Accurate inventory, every channel
Real-time, bi-directional sync between your WMS and each client's storefronts, so stock never drifts and no one oversells.
03
Every merchant in one platform
Your team sees every merchant's orders, inventory, and exceptions in one place and builds workflows the same way across accounts. Fewer one-off connections to maintain means simpler operations and less risk.
04
Labels, tracking, and returns handled
Shipment confirmations, labels, tracking, and returns flow between your WMS, your shipping platform, and every channel automatically, so the warehouse, the carrier, and the storefront all agree.
How It Works
Your merchants' orders automatically flow to your WMS.
DropStream connects your WMS to your merchants' channels and keeps order, inventory, and tracking data in sync.
What gets mapped
DropStream's rules engine translates each channel into the format your WMS expects: SKU mapping, client and account routing, shipping method translation, and per-client business rules.
What flows back
Shipment confirmations, tracking numbers, and inventory levels sync back to each client's carts and marketplaces so their listings and order status stay accurate.
What we monitor
Every sync, every client, every minute. If something breaks (a rate limit, a data mismatch, an API outage), DropStream alerts you before your client does.
Autonomous Fulfillment
AI can run your warehouse. Only if the data is right.
WMS platforms are adding AI: automated slotting, rate shopping, predictive labor, and robotic picking that promise a warehouse that runs itself. But autonomy is only as good as the data behind it. If an order arrives late or inventory is wrong, the system makes a bad decision faster than a person would.
DropStream syncs orders and inventory between your merchants' channels and your WMS in real time, and catches disruptions the moment they happen. DropStream isn't an AI solution. It's the accurate, real-time data foundation that autonomous fulfillment runs on.
