Is the supplier the last to know? It doesn’t have to be that way. In order to facilitate pre-deduction notifications, the retailer will typically require the supplier to set up a group email address – for example,– for notifications to be forwarded to. The supplier then has to make sure all appropriate personnel in the company are associated with this e-mail distribution. Another way to access this information may be through the retailer’s web portal, for which there are automated means to access.
