Your 3PL and ERP Should Talk In Real Time
When your 3PL warehouse and ERP system are disconnected, you get phantom inventory, late shipments, and customer service nightmares. We build integrations that keep both systems perfectly in sync — so what your ERP shows is what your warehouse actually has.

Our engineers are certified across leading WMS platforms and ERP systems used in logistics.
Complete 3PL-ERP Integration — From Receiving Dock to Customer Doorstep
Not just a data sync. We build intelligent logistics pipelines that keep your ERP, warehouse, and customers aligned in real time.
Real-Time Inventory Synchronization
Bi-directional inventory sync between your ERP and 3PL WMS — including lot tracking, serial numbers, expiration dates, and multi-location quantities updated every 5 minutes or on-demand.
Automated Order Routing
Orders from your ERP are automatically routed to the optimal 3PL warehouse based on inventory availability, shipping zone, carrier rates, and delivery SLAs — no manual allocation needed.
Shipment Tracking & Delivery Updates
Carrier tracking numbers, shipment status, and proof of delivery flow back into your ERP automatically — updating sales orders, triggering invoicing, and feeding customer notification systems.
Returns & RMA Processing
When a 3PL receives a return, your ERP knows immediately — creating credit memos, updating inventory, triggering quality inspection workflows, and closing the loop with the customer.
Receiving & Putaway Integration
Inbound purchase orders sync to your 3PL for receiving. When goods are checked in, quantities, lot numbers, and storage locations flow back to your ERP for accurate inventory and AP matching.
Billing & Cost Reconciliation
3PL storage fees, pick-and-pack charges, and shipping costs are automatically matched against your ERP's expected costs — flagging discrepancies before you pay the invoice.

A 3PL integration isn't just plumbing — it's the nervous system of your supply chain.
We've connected brands to 3PL providers across the US, Europe, and Asia. Whether you're running one warehouse or seven, the integration has to be fast, accurate, and smart enough to handle exceptions without human intervention.

What Our Clients Say
“We were spending 20 hours a week manually syncing inventory between our ERP and two 3PL warehouses. OpenMalo built a real-time integration in 5 weeks. Now our inventory is accurate within 15 minutes and we've eliminated overselling completely.
“Our 3PL integration used to break every Black Friday. OpenMalo rebuilt it with proper queuing and retry logic, and last year we processed 40K orders in 48 hours without a single sync failure. That's never happened before.
“The best part isn't the automation — it's the visibility. I can see exactly where every order is, what's in every warehouse, and what's about to run out, all from our ERP dashboard. We used to guess at half of that.
96% Inventory Accuracy Across 3 Warehouses
3PL-ERP Integration at Velocity Commerce
How we connected a fast-growing D2C brand's ERP to three 3PL warehouses — eliminating overselling, cutting fulfillment costs by 38%, and enabling same-day shipping for 85% of orders.
Disconnected warehouses causing overselling and delayed shipments
Velocity Commerce was growing 3x year-over-year but their ERP had no real-time connection to their three 3PL warehouses. Inventory was synced via daily spreadsheets, orders were routed manually, and overselling during promotions was costing them $25K a month in refunds.
Our Approach: 2-week logistics audit, phased integration over 5 weeks covering inventory sync, intelligent order routing, shipment tracking, and returns — with peak-season load testing and real-time monitoring dashboards.
