Good product data is essential to driving sales. This article explains Avasam's data requirements and the error messages you will see when a product does not meet those requirements.
As you're providing the information sellers will use when listing your products, the better the quality, the better the listing they can create. This encourages them to source and sell your products, and reduces the chance of returns due to 'Not as described' claims, for example.
As such, we check all products before making them live, and we check any changes provided before updating products to maintain a good standard within the catalogue.
Products that fail our minimum data requirements will be held in our product staging environment and will require data corrections before they can be made live on the platform
