Stop losing sales to lag — get multichannel inventory sync across every channel
Redefine Channel Sync delivers multichannel inventory sync, reading directly from your native order management system. Inventory, orders, prices, and content stay accurate on every marketplace the moment something changes. No third-party sync tool. No polling delay.

Every sync gap is a lost sale waiting to happen
Multichannel brands running disconnected inventory sync software oversell, upset buyers, and absorb penalties. The root cause is always the same: inventory truth lives in one system, sync logic lives in another.
- Oversells from stale inventory counts
Your order management system says 12 units. Your sync tool polled 4 minutes ago. Amazon shows 12. You have 2.
- Order acknowledgment lag triggers cancellations
Marketplaces cancel orders when acknowledgment takes longer than their service level agreement window.
- Price sync mismatches cause repricing violations
A pricing rule changes at 9am. Your sync tool pushes it at 9:47am. Competitors undercut you in the window.
- Content updates require manual re-upload per channel
One product description change means re-exporting feeds for Amazon, Walmart, and eBay separately.
- Conflict resolution is a manual daily task
Two channels claim the same stock. Nobody has a priority rule. Someone's order gets cancelled.
- Order management system is the single inventory source of truth
Multichannel inventory sync reads directly from the native order management system. There is no poll interval. Every channel reflects live stock.
- Orders auto-acknowledged the moment they arrive
Multichannel order sync routes orders to the order management system in real time and fires acknowledgment back before the service level agreement window closes.
- Channel-specific price rules push on change
Markup and markdown rules apply per channel and push the moment the base price changes. No window, no lag.
- Product information manager change triggers automatic field updates everywhere
Update once in product information manager. Content sync propagates the change to every connected channel automatically.
- Priority rules resolve channel conflicts automatically
Define which channel wins when stock is contested. Rules run silently. No manual intervention needed.

Every channel, every update, one live view
The Channel Sync dashboard puts multichannel inventory sync, order acknowledgment status, price sync health, and content propagation across every connected channel into one real-time view.
| Channel | Inventory | Orders | Price Sync | Content | Last Sync |
|---|---|---|---|---|---|
| Amazon US | Live | 12 acknowledged | Synced | Up to date | 3s ago |

From order management system change to every channel in under 5 seconds
As marketplace sync software, Channel Sync sits between your native order management system and every connected marketplace. It listens for changes and pushes them immediately. No polling. No middleware. No separate sync subscription.
| Channel | Price Rule | Priority | Buffer |
|---|---|---|---|
| Amazon US | +12% | P1 | 2 units |
| Walmart | +8% | P2 | 1 unit |
| eBay | +5% | P3 | 0 units |
Marketplace sync software: five sync types, one unified layer.
Real-time inventory sync software
As inventory sync software, the platform propagates every inventory movement in the order management system to all connected channels instantly. No polling. No stale counts. No oversells.
Multichannel order sync and acknowledgment
Multichannel order sync routes orders from every channel to the order management system automatically. Acknowledgment fires back before marketplace service level agreement windows close. Zero cancellations from late acknowledgments.
Price sync with channel rules
Set markup or markdown rules per channel. Base price changes in your pricing engine push immediately to every channel with the correct rule applied.
Content sync from product information manager
Update a description, image, or attribute in product information manager once. Content sync pushes the change to every channel automatically. No re-upload. No feed re-export.
Conflict resolution and priority rules
Define which channel wins when two channels compete for the same stock. Rules run automatically. No one on your team makes a manual call at peak load.
Native order management system connection
As channel management software, Channel Sync reads inventory and order state directly from the platform's native order management system. No third-party sync tool subscription. No integration to maintain. One source of truth.
Real-time sync scaled a multichannel retailer to $6 million

An online retailer selling branded sunglasses and eyeglasses across Shopify and multiple external marketplaces.
Rapid growth across multiple marketplaces created operational complexity. Multichannel inventory sync in real time was unreliable. Manual processes limited scalability and created fulfillment errors across channels.
Real-time inventory sync across all channels, automated restocking alerts, and consolidated multichannel order management enabled Eyeglasses123 to scale from manual operations to $6 million in annual revenue with reduced overhead.

Channel management software that syncs the entire operation, not just feeds.
Every other channel management software is a middleware layer bolted on top of your order management system. Redefine Channel Sync reads directly from the same order management system your warehouse team uses. One source. Zero translation layer.
No polling interval
Most inventory sync software polls your order management system every 5 to 15 minutes. Redefine reads on change. The moment order management system updates, channels update.
No third-party tool subscription
This marketplace sync software is native to the platform. You pay nothing extra for the sync layer. No API key. No integration maintenance. No monthly sync tool fee.
Closed-loop error correction
When a sync error is caused by a missing product information manager field, the platform auto-creates a product information manager enrichment task. The error fixes itself without manual handoff.
| Capability | Typical sync tool | Redefine |
|---|---|---|
| Inventory sync source | Third-party API poll | Native order management system: on change |
| Sync latency | 5 to 15 minute polling window | Under 5 seconds |
| Order acknowledgment | Batch, delayed | Real-time, automated |
| Price rules per channel | Manual rule setup per tool | Native, per-channel rules |
| Content propagation | Manual re-feed per channel | Auto-push from product information manager |
| Conflict resolution | Manual daily review | Automated priority rules |
| Error auto-correction | Manual ticket creation | Product information manager enrichment task auto-created |
| Additional subscription cost | Yes, per tool | None: native to platform |

Frequently asked questions
Feed management tools build and schedule product feeds for listing creation. Channel Sync handles the operational layer: real-time inventory state, order acknowledgment, price propagation, and conflict resolution. Both exist in Redefine but serve different jobs. Feed management publishes your catalog. Channel Sync keeps it accurate after publication.
No. Channel Sync is native to the Redefine platform. It reads directly from the same order management system that handles your warehouse and fulfillment operations. There is no separate tool, no API key to manage, and no third-party sync subscription to maintain. The sync capability is included in the platform.
You configure a ranked priority list per channel in the platform. When a conflict is detected, the system allocates available stock to the highest-priority channel first, updates counts on all other channels immediately, and logs the resolution event. No manual intervention is required at the time of the conflict. You review the log after the fact.
Channel Sync identifies the missing field and auto-creates a product information manager enrichment task assigned to the relevant product team. Once the product information manager record is completed, the sync retries automatically. The listing error resolves itself without a support ticket, a manual re-export, or any message between teams.
Channel Sync connects to all marketplaces supported by the Redefine Marketplace and Channel Management product, which includes Amazon, Walmart, eBay, Etsy, Facebook, Target Plus, Best Buy, Home Depot, and 100 or more additional channels. New marketplace connections reuse your existing product information manager catalog, order management system routing, and pricing rules without re-configuration per channel.
