TonerOne sells thousands of toner and ink SKUs on eBay. Stock and prices were updated by hand, so items oversold when warehouse stock ran out, and every order was retyped into Odoo for fulfilment and invoicing.
They needed Odoo to be the single source of truth for products, stock and orders across marketplaces.
Stock and price changes in Odoo flow to every eBay listing within minutes.

Overselling
eBay quantities lagged behind real stock, leading to cancellations and seller-rating penalties.
Stock changes in Odoo trigger near-real-time quantity updates to eBay, with safety buffers per SKU and automatic delisting at zero stock.
Thousands of compatible-model variants
Toner listings need printer compatibility data and item specifics that didn't exist in Odoo.
We extended the Odoo product model with compatibility tables and eBay item specifics, then generate listings from templates in bulk.
API rate limits
Bulk price and stock updates hit eBay call limits.
Updates are batched through eBay's bulk endpoints with a throttled queue and change-detection, so only modified listings are sent.
- OAuth connection to one or more eBay seller accounts
- Bulk listing creation with item specifics and compatibility
- Real-time stock and price sync with buffers
- Automatic order import with customer and tax mapping
- Tracking numbers and fulfilment pushed back to eBay
- Sync logs, error queue and retry dashboard
