Premium Capability.
Fair Pricing.
Octopus 3.0 is the all-in-one multi-channel connector that syncs pricing, inventory, listings, fitment data and orders across Amazon, eBay, Walmart, BigCommerce and Shopify — purpose-built for automotive and heavy-duty parts sellers.
The Challenge
Selling in more places shouldn't mean more chaos.
Retailers and distributors expanding across their own storefront and marketplaces like Amazon, eBay, Walmart, BigCommerce and Shopify quickly run into the same wall: disconnected listings, inconsistent fitment data, stale inventory counts, and no single view of performance.
A unified multi-channel connector isn't a nice-to-have anymore — for automotive and heavy-duty parts sellers managing ACES/PIES fitment data across five or more channels, it's the need of the hour.
Common pain points Octopus solves
- Manually re-entering listings and fitment data on every marketplace
- Overselling or stockouts from unsynced inventory
- No visibility into delisted or error-flagged SKUs
- Disconnected ERP/PIM data and marketplace catalogs
- Slow, generic tools that don't understand automotive fitment
