Oversells

The invisible tax on
multichannel brands.

These problems cost you revenue every day — and most brands don't realize how much until they fix them.

Overselling on Marketplaces

A sale on Shopify doesn't update Amazon fast enough. The same item sells twice. You cancel an order, refund the customer, and take the reputation hit.

Hours Lost to Reconciliation

Your team spends hours every week cross-referencing spreadsheets, manually adjusting stock levels, and hunting for discrepancies across channels.

Lost Sales from Phantom Stock

Items show 'out of stock' on one channel while sitting in a warehouse or available through another location. Revenue slips through the cracks silently.

Peak Season Panic

Black Friday, flash sales, product drops — your team holds their breath because one sync delay could mean thousands in oversold orders.

Watch it happen. In real time.

See how a single sale triggers instant stock updates across every connected channel.

Stock propagates to every channel in under 5 seconds. No webhooks. No polling. Event-driven sync.

From sale to sync in
under 5 seconds.

Every sale triggers an instant cascade of updates across your entire channel network. Here's how it works.

1

Sale Happens

An order comes in on any connected channel — Shopify, Amazon, eBay, your online store, or POS.

2

Stock Adjusts Everywhere

Inventory decrements propagate to every connected channel in under 5 seconds. No polling, no delays.

3

Conflicts Resolve

If two channels sell the last item simultaneously, locking mechanisms prevent double-selling. One order ships, one gets flagged.

4

Alerts Fire

Low stock alerts, reorder notifications, and safety stock triggers keep your team ahead of stockouts.

Built for multichannel
inventory complexity.

Every feature designed to eliminate overselling, reduce manual work, and give you complete control over stock across every channel.

Sub-5s Sync

Event-driven inventory updates push to every channel in under 5 seconds. No polling, no batch jobs, no delays.

Multi-Location Management

Track stock across warehouses, stores, FBA, and 3PLs. Each location has independent levels, safety stock, and reorder points.

Low Stock Alerts

Automated notifications when stock hits your thresholds. Set alerts per product, variant, location, or channel.

Bundle & Kit Tracking

Sell bundles while tracking component-level inventory. When a kit sells, every component decrements across all channels.

Audit Trail

Every stock change is logged with timestamp, source, and reason. Full visibility into who changed what and when.

Safety Stock Buffers

Reserve inventory per channel to prevent overselling during peak periods. Configurable buffers that adjust dynamically.

Your Inventory is the Single Source of Truth.

Every channel reads from one ledger. When stock moves anywhere, every connected platform knows within seconds — no polling, no cron jobs, no reconciliation spreadsheets.
