Smart scale service aimed at business market.

Amazon has re-structured its automatic product re-ordering platform with the release of a new Wi-Fi-enabled smart scale.

Having launched the pre-ordering platform via its Dash buttons in 2015, Amazon discontinued the service in the US earlier this year and has replaced it with the Amazon Dash Smart Shelf, a weight-sensing, WiFi-enabled smart scale designed to take the hassle out of office supply management for small businesses.

The device can be placed on a stock room shelf or canteen countertop and will automatically track inventory for common business supplies, such as stationery, coffee or printer paper.

The system works by keeping the item to track on top of the shelf, and it will sense when a product is running low. It'll automatically re-order more or send reminder to place a re-order manually.

The shelf comes in three sizes and is managed through the Amazon Shopping app or an Amazon Business account.

Amazon Business customers in the US are able to access business-only prices and savings of up to 15 per cent on the products they monitor and purchase using the shelf.

The Dash Smart Shelf will be available to Amazon Business customers with a registered US business license starting next year.
