We currently have two BigCommerce stores (one for USA, and one for Germany) and are looking for a developer to build us a customized backoffice (crm) to work with both of these shops. We are looking for a backoffice that allows you to upload a customized excel document (including variations on products) easily to both shops (by selecting if the goods go into one or both stores) as well as a backoffice that stores vendor information and allows us to track the status of conversation, and keeps track of data/sales from each partner. We would like to easily be able to filter top products, partners, etc and see all valuable information including margin. Additionally we would like the backoffice to store images for each partner in a way that is easily accessible. Backoffice and linesheet must synch up with (or replace) current drop shipping app called Appath. Information from line sheet should be automatically entered into the Appath system, so we are not doing double work. If this is not possible, we would like to figure out a relatively simple drop shipping solution. Should include a stock notification and inventory management solution. Also need a calendar function that allows us to view what sales are going live on the site at what time, and forecasted revenue (that changes to real time). Must have bulk editing functionality. Our website has "regular" sales, as well as "limited discounted sales" so must be able to support that.
