01 · What you get

What a ChannelEngine integration gives you.

Orders ingest without manual re-entry

Marketplace orders arrive automatically into your order queue with customer, product and shipping details pre-mapped, eliminating manual data entry and reducing order processing time.

Inventory stays synchronised across channels

Stock levels update consistently across Amazon, eBay and other channels, preventing customers from purchasing items that are already sold elsewhere.

Pricing changes propagate in minutes, not days

Promotional pricing and permanent price changes sync to all active channels through ChannelEngine without manual re-listing or spreadsheet exports.

Channel-specific returns flow back to ERP

Return notifications from each marketplace are captured, validated and forwarded to ERP for credit note generation and inventory adjustment in a consistent workflow.

Operational cost per channel drops

By centralising channel data and rules in ChannelEngine, you eliminate duplicate catalogue maintenance, redundant pricing updates and manual order reconciliation.

02 · When it's worth it

Where a ChannelEngine integration earns its place.

If two or more of these are true, the integration usually pays for itself quickly.

Publish product listings and inventory to Amazon, eBay and Zalando without manual re-entry
Synchronise pricing and promotional rules across all active channels in real time
Ingest orders from multiple marketplaces into a unified order queue for picking and dispatch
Manage channel-specific returns and refunds without fragmenting processes
Prevent oversell by applying shared inventory buffers across channels
Route channel orders to the correct warehouse or fulfilment provider
03 · The limits

Where off-the-shelf connectors fall short.

Vendor connectors are fine for simple cases. Here's where the real ones need more.

Channel-specific product rules not templated

ChannelEngine handles feed translation but does not automate business logic rules specific to individual channels. Rules around mandatory fields, prohibited content, image requirements or variant hierarchies must be manually configured or scripted.

No built-in inventory buffer intelligence

Stock buffers and safety levels are static configuration, not dynamic. You must manually set per-channel thresholds; ChannelEngine does not learn optimal buffers from oversell incidents or forecast demand across channels.

Limited pricing rule expressiveness

Pricing sync supports base prices and simple markups, but complex rules such as margin-preservation across currencies or cost-plus-margin calculations must be pre-computed and fed to ChannelEngine, not configured within it.

Returns and refund flow requires manual mapping

ChannelEngine ingests marketplace return events but does not automate refund authorisation or credit note generation in ERP. You must manually review returns, determine credit terms and trigger ERP transactions.

No real-time inventory visibility across channels

Inventory updates are batch-based, not event-driven. In high-velocity selling, stock levels published to channels may lag behind actual warehouse movements, increasing oversell risk during peak periods.

04 · The real work

The friction point most merchants face is not connecting to a single marketplace—it is synchronising inventory, pricing and order data consistently when the same product is sold across five channels, each with its own feed format, stock tolerance and refund policy.

05 · Where it sits

Where this integration sits in your estate.

ChannelEngine holds the commercial record. The iWeb integration layer manages the rules, mappings, monitoring and exceptions. The commerce platform presents the customer-facing experience. The estate map helps agree ownership before anything is built.

Storefront independent. ChannelEngine feeds stock, pricing, orders and customer data into your chosen platform.

07 · Data flows

The data flows we wire.

Each flow has a direction and an owner. We agree both before a line of code is written.

Into SALES CHANNELS & COMMERCE & ERP
Product catalogue feed: Merchandise listings, product descriptions, images and attributes flow from your commerce platform into ChannelEngine, which then distributes them to each connected marketplace in the format and structure that channel requires.
Pricing and promotion sync: Base pricing, tiered pricing and channel-specific promotional rules travel from your commerce platform or pricing engine through ChannelEngine to each marketplace, with ChannelEngine managing channel-specific rounding and currency conversion.
Inventory allocation: Available stock quantities flow to ChannelEngine, which applies per-channel buffers and safety thresholds, then publishes the calculated quantity to each marketplace to prevent oversell.
Marketplace orders and events: Customer orders, returns requests and cancellation notifications arrive from each marketplace into ChannelEngine, which normalises them into a standardised order format and forwards them to your commerce platform and order management system.
Dispatch instructions and tracking: Once orders are confirmed in your system, ChannelEngine receives dispatch instructions and tracking updates, then routes them back to each marketplace so buyers see real-time shipment status.
08 · How we build it

How iWeb configures the integration around your business.

Same method on every integration. The decisions come before the code.

  1. 01
    Design channel data governance

    We define which team owns channel-specific content rules, pricing tier application and stock buffer settings, ensuring changes are logged and reviewed before deployment to ChannelEngine.

  2. 02
    Integrate ChannelEngine with your ERP

    We map marketplace orders ingested by ChannelEngine into your ERP's order schema, ensuring financial records match commerce transactions and reconciliation is auditable.

  3. 03
    Build inventory allocation logic

    We implement per-channel stock buffers and safety thresholds that reflect your warehouse capacity and channel-specific demand patterns, then feed them to ChannelEngine as configuration.

  4. 04
    Establish monitoring and alerting

    We instrument ChannelEngine feed flows, order ingestion and dispatch tracking so you see feed delays, malformed data or channel outages immediately rather than discovering them from customer complaints.

  5. 05
    Test channel failover and recovery

    We validate that when ChannelEngine or a marketplace temporarily fails, orders are safely queued and resent once the channel recovers, with no loss or duplication.

09 · Ownership

10 · Experienced integrator

Built multi-channel order flows before

iWeb understands how ChannelEngine sits between your commerce platform and multiple external marketplaces, and how to design reliable data flows without oversell, order loss or reconciliation drift. We have integrated inventory allocation, pricing synchronisation, order ingestion and fulfillment tracking into estates where stock and orders move across channels and systems simultaneously.

We design inventory buffer and allocation rules that prevent oversell while maximising channel availability, including fallback logic when ChannelEngine is temporarily offline.
We build order normalisation and idempotency handling so orders from ChannelEngine are ingested into your commerce platform and ERP without duplication or loss.
We implement monitoring and alerting that surfaces feed delays, validation failures, channel outages and reconciliation gaps before they affect your business.
We integrate ChannelEngine with your ERP's order and financial workflows, ensuring channel orders reconcile correctly and refunds flow back to credits and inventory adjustments.
We define governance so product owners, pricing teams and operations know who owns each channel-specific rule and how changes are approved before being pushed live.
11 · Before launch

What we test before launch.

Every one of these is rehearsed before a customer ever sees the integration.

Verify that inventory updates from your warehouse reach ChannelEngine within your target SLA and that published quantities match your buffer settings per channel.
Confirm that orders from each connected marketplace appear in your order queue with correct item SKUs, customer details and shipping addresses before dispatch is triggered.
Test the oversell scenario: sell out an item on one channel and confirm the inventory on other channels updates within 2-5 minutes to prevent duplicate sales.
Validate that dispatch confirmations and tracking numbers flow from your fulfillment system through ChannelEngine back to each marketplace so customers see updates.
Simulate a ChannelEngine outage: confirm that orders already in your system are not lost, and that once ChannelEngine recovers, queued orders are ingested without duplication.
Check that refunds or cancellations initiated on a marketplace are captured by ChannelEngine and routed to your order and finance systems for reconciliation.
Confirm that pricing changes made in your system reach all active channels and are reflected on the marketplace within your acceptable lag (typically 5-30 minutes).
12 · Failure points

Common risks and where they bite.

We name these on day one. A risk written down is a risk you can plan around.

Oversell across channels during peak periods

If inventory updates to ChannelEngine lag warehouse stock movements, customers on multiple channels may simultaneously purchase the same item. This happens most often during flash sales or limited-stock events.

Orders lost or duplicated when ChannelEngine is unavailable

If ChannelEngine goes offline or your connection fails, orders from marketplaces may queue indefinitely or be re-ingested after reconnection, creating duplicate orders in your system.

Pricing mismatches between channels and ERP

If pricing rules are updated in your system but not pushed to ChannelEngine, or if ChannelEngine fails to acknowledge a price change, channels may display stale pricing and customers may place orders at incorrect prices.

Returns and refunds not reconciled to ERP

Marketplace return notifications arrive in ChannelEngine but may not automatically trigger refund or credit note transactions in ERP, leaving accounting records incomplete and customers waiting for refund confirmation.

Channel-specific rules silently drift

If channel data mappings, image requirements or field specifications are not version-controlled, marketplace feeds may begin failing silently or publishing incomplete product records without alerting you.

14 · Questions

Common questions about ChannelEngine integrations.

How do I prevent oversell when the same product is listed on multiple channels?

ChannelEngine manages per-channel inventory buffers. You configure a safety threshold for each channel (e.g. 80% of warehouse stock published to Amazon, 60% to eBay). ChannelEngine recalculates available quantity for each channel based on the buffer, then publishes it. However, buffers are static; you must manually review oversell incidents and adjust thresholds. Real-time synchronisation requires your warehouse system to push stock updates to ChannelEngine immediately after each sale or return.

What happens to marketplace orders if ChannelEngine is offline?

While ChannelEngine is unavailable, new orders from marketplaces are held by those marketplaces' servers. When ChannelEngine reconnects, it retrieves pending orders. However, there is a risk of duplicate ingestion if orders are re-fetched after reconnection. iWeb implements an idempotency check in your system so duplicate orders are detected and suppressed before they reach ERP.

How are marketplace returns and refunds reflected in my ERP?

ChannelEngine ingests return notifications from marketplaces, but it does not automatically generate ERP credit notes or refund transactions. iWeb builds a workflow where returns are queued for review, approved by your finance or customer service team, then a credit note is created in ERP and the refund is confirmed back to ChannelEngine. This keeps accounting records reconciled.

Do I need to maintain product data in multiple places?

No. You maintain your product data in your commerce platform or PIM as the single source. ChannelEngine then fetches catalogue feeds from your system and translates them into the format each marketplace requires. However, channel-specific requirements (such as image size, mandatory fields, prohibited attributes) must be known and configured in ChannelEngine or your upstream system.

How quickly do pricing changes propagate to all channels?

ChannelEngine supports scheduled or immediate price syncs. If you update pricing in your system and trigger a feed to ChannelEngine, most marketplaces acknowledge the change within minutes. However, some marketplaces have their own caching layers, so the time from price change in your system to visibility on the marketplace can be 5-30 minutes depending on the platform.

Can ChannelEngine handle channel-specific pricing (e.g. different prices on different marketplaces)?

Yes. ChannelEngine supports channel-specific pricing rules. You can define a base price and then override it with a multiplier or fixed price per channel. However, complex rules such as margin preservation across currencies or dynamic discounts based on competitor pricing must be pre-calculated and fed to ChannelEngine, not configured within it.

What if a marketplace is down or not accepting uploads?

ChannelEngine queues updates and retries according to its retry policy. However, if a marketplace rejects updates silently (e.g. due to a validation rule change), ChannelEngine may not alert you. iWeb builds monitoring and alerting so you see feed failures, validation errors and delivery delays immediately.

How do I reconcile channel orders in my accounting system?

Orders ingested from ChannelEngine flow into your commerce platform, which then creates web orders in your ERP. For reconciliation, iWeb ensures each marketplace order is tagged with its source and order ID so you can trace it back to the original marketplace order, invoice and payment. This is especially important for multi-currency orders where exchange rates must match.

Can I use ChannelEngine with a Other storefronts?

ChannelEngine is primarily a marketplace connector. It syncs between your commerce platform and external marketplaces like Amazon and eBay. If your storefront is headless, ChannelEngine connects to your commerce backend (the API and order system), not the frontend, so the architecture of your storefront does not affect ChannelEngine integration.

Who owns the decision about which channels to list on and which inventory levels to allocate?

Channel strategy and inventory allocation decisions belong to your business teams. iWeb helps you define roles: who can add a new channel, who approves changes to stock buffers, who reviews pricing tier changes. These decisions are then encoded as ChannelEngine configuration or workflow rules so the system enforces them.

What happens to tracking information once an order ships?

Once your warehouse or 3PL confirms dispatch, they send tracking details to your fulfillment system. From there, ChannelEngine retrieves tracking numbers and forwards them back to each marketplace so customers see real-time shipment status. If tracking is delayed or missing, customers will complain to the marketplace, which may affect your seller rating.

How do I know if ChannelEngine is in sync with my inventory?

iWeb implements monitoring dashboards that show the lag between your warehouse stock and what ChannelEngine published to each channel. We also alert you if the published quantity differs from the calculated quantity (suggesting a buffer change or sync failure) or if oversell incidents are detected after the fact.

Can ChannelEngine manage returns and RMAs?

ChannelEngine captures return notifications from marketplaces. However, ChannelEngine does not manage the full RMA workflow (inspection, refund decision, restocking). iWeb connects ChannelEngine to your returns management system, so returns notifications are automatically logged and routed to your team for decision-making.

What should I do if ChannelEngine fails during my peak trading period?

iWeb designs a fallback: if ChannelEngine is unavailable, orders from marketplaces queue on the marketplace servers until ChannelEngine recovers. Once it reconnects, pending orders are retrieved. However, you should also have a manual process: a team member can download pending orders from each marketplace and manually upload them to your order queue so fulfillment is not delayed.
