Your Warehouse.
Your Stack.
Our Brain._
Pure-API warehouse orchestration. No UI. No rip-and-replace. Plug discrete, callable services into the ERP, OMS, or TMS already running your operation — and watch every warehouse event resolve itself.

}Every warehouse function.
A discrete endpoint.
No bundled UI. No module licenses. Call exactly the capabilities your operation needs, from the system that already runs it.
Inbound ASN Processing
Receive supplier advance ship notices, auto-create putaway tasks, and update on-hand in <50ms. Works with any EDI 856 or JSON payload.
Real-Time Inventory Allocation
Split-optimal allocation across up to 40 warehouse nodes. Reads live ATP, respects reservation rules, returns allocation plan in a single call.
Wave Planning Engine
Generate pick waves by carrier cutoff, zone, order priority, or custom rule sets. Expose the planner as a callable service — trigger from your OMS or cron.
Dynamic Slotting Optimization
Velocity-based slot assignments recalculated nightly or on-demand. Feed SKU velocity data from your analytics layer; receive putaway recommendations.
Carrier Rate Shopping
Compare live rates across FedEx, UPS, USPS, DHL, and regional carriers in one call. Returns ranked options with ETA, cost, and carbon estimate.
Cycle Count Orchestration
Schedule directed cycle counts by location, zone, or SKU class. Sync count results back to your ERP inventory ledger via configurable webhook.
Labor Task Management
Assign, reassign, and track warehouse tasks without a WMS UI. Your workforce app calls this endpoint; workers never touch a legacy screen.
Real-Time Event Stream
Subscribe to warehouse events — receipt confirmed, pick complete, shipment created — as they happen. Pipe to Kafka, SQS, or any webhook consumer.
What legacy WMS calls
"features" — we call bloat.
Every capability in a traditional WMS is bundled, locked, and billed as a unit. Headless exposes each function as a discrete, callable service. Use what you need. Skip what you don't.
Sub-50ms real-time sync via webhook or polling. Your OMS calls one endpoint; all nodes update atomically.
Batch sync every 15–30 min. Requires middleware adapter. Oversells happen between sync windows.
Live rates from 12+ carriers in one API call. Returns ranked options with ETA + carbon data.
Locked to contracted carriers. Rate shopping requires separate TMS integration or manual process.
Callable from any OMS trigger. Custom rule sets via config. No UI required to generate a wave.
Planner lives inside the WMS UI. Requires trained staff. Not callable from external systems.
Native webhooks for SAP, NetSuite, D365. Schema maps configurable via API. Zero middleware.
Custom integration project. 6–18 month implementation. Brittle EDI or flat-file handoffs.
Billing events emitted per warehouse action. Feed directly to your billing engine. Automates 100% of 3PL charge capture.
Manual billing reconciliation. Labor-intensive. Errors common at month-end close.
No UI shipped. Build exactly the interface your team needs on top of our API. Or use none at all.
Bundled UI you pay for whether you use it or not. Customization requires vendor professional services.
Zero-downtime continuous delivery. New endpoints available same day. No upgrade windows.
Scheduled maintenance windows. Major version upgrades every 12–24 months. Regression risk.
Provision a new warehouse node via API. Configuration inherits from parent. Live in <4 hours.
New site implementation: 8–16 weeks. Requires on-site consultant. Full license fee per node.
Plugs into the stack
you already run.
No middleware layer. No integration platform tax. Native connectors for every major ERP, OMS, TMS, and carrier — plus a universal webhook for anything custom.
Bidirectional order sync. Inventory updates pushed on every warehouse event. Oversell prevention built in.
Real-time GL entries on every receipt, shipment, and adjustment. No flat-file handoffs.
IDocs replaced with REST. Inventory and transfer orders sync without ABAP customization.
Use Headless for orchestration logic while Manhattan handles directed RF tasks at the floor level.
Live rate shopping, label generation, and tracking webhooks. Ground, Express, and Freight.
Full UPS API surface: rates, labels, void, tracking. Negotiated rates applied automatically.
Trigger Amazon Multi-Channel Fulfillment for non-Amazon orders directly from your OMS.
Proprietary ERP? In-house OMS? Configure any webhook target. Schema mapping via JSON config.

Single event stream at /v1/events/stream
Eliminate middleware layer
Inventory sync lag causing oversells
Sub-50ms real-time sync via webhook
Zero oversell incidents
New warehouse node takes 8–16 weeks
Provision via POST /v1/nodes/provision
