Good to Know

Platform restrictions outside any integration tool's control

BigCommerce B2B Edition customer groups on Amazon

Amazon does not support tiered or customer-group pricing. B2B-specific pricing from BigCommerce B2B Edition cannot be replicated on Amazon's consumer marketplace.

Amazon A+ Content creation

A+ Content / Enhanced Brand Content is managed in Seller Central's Brand Registry. No third-party API write access is available.

Cross-storefront product differences

If the same SKU has different descriptions or images on different BigCommerce storefronts, only one version can be sent to Amazon. Storefront-specific content must be reconciled.

Things to Consider

Platform-specific details and how they affect this integration.

Challenge

BigCommerce multi-storefront allows different storefronts to share or isolate inventory pools. When Amazon draws from the same pool as multiple storefronts, a high-volume Amazon sale day can deplete stock that B2B and B2C storefronts also depend on — creating availability conflicts that are difficult to predict.

Nventory's Approach

Nventory gives you control over how Amazon interacts with your storefront inventory pools. You can allocate a dedicated Amazon stock buffer, share the full pool, or set per-storefront reserve quantities that are protected from Amazon sales.

Frequently Asked Questions

Yes. Nventory treats Amazon as an additional channel alongside your BigCommerce storefronts, coordinating inventory across all of them from a unified pool.

Absolutely. Nventory supports bulk product mapping and syncing for catalogs with tens of thousands of SKUs, leveraging BigCommerce's high-performance API.

Yes. Your B2B storefront products can be selectively listed on Amazon for consumer sales while keeping B2B-specific pricing and customer groups separate in BigCommerce.

You can set Amazon-specific pricing rules that differ from your BigCommerce storefront prices, with per-storefront and per-Amazon-region control.

Nventory syncs inventory between BigCommerce and Amazon within 2-5 minutes of a stock change on either platform. BigCommerce's high-performance API enables faster data throughput, which is especially beneficial for large catalogs with tens of thousands of SKUs.

Nventory matches BigCommerce SKUs to Amazon ASINs using SKU, UPC, or EAN during the initial product mapping phase. Unmatched items are flagged in a review queue with suggested ASIN matches based on product attributes, so you can resolve mismatches without manual Amazon catalog searches.

The most common cause is a webhook delivery failure — check Nventory's sync log for missed events and re-trigger any failed product updates manually. If webhooks appear healthy, verify that your BigCommerce API token has not expired or been regenerated, as an invalid token silently stops all outbound data to Amazon. Also review your catalog sync settings in Nventory to confirm that the specific product fields you expect (titles, descriptions, images) are mapped and enabled for Amazon.
