Building a RMA (Return Goods Authorization) webapplication

We are looking for a RMA tool which is similar as RMAportal.com. The application needs to be available in the cloud (web-based) and include the following features: Review, reject or approve new RMA Requests Review, reject or approve existing RMA Cases Assign automatically generated RMA Numbers. Support for custom formatting of RMA Number. Support for manual RMA Number assignment. Automatic email sent to customer upon RMA Case Approval and status update. Support for multiple vendor receiving centers Reject or Approve individual items from multiple-itema RMA Support for encoding individual item status like Warranty Status, Inspection Findings, Item Resolution, and Item Disposition. Admin can fully configure the list of selections that appear on Return Reason Codes, WARRANTY STATUS, Inspection Findings, Item Resolution, and Item Disposition. Support for automatic Product Code Validation, it must validate product codes and automatically rejects invalid codes. Support for automatic Serial Number Validation, it must validate product codes and automatically rejects Serial Numbers. Customer can do a quick status check just by entering a Tracking Number. Customer upload attachments (picture files like JPG, GIF, PNG and PDF documents) to an RMA request A scannable Code 3 of 9 barcode can be printed on customer's Packing Slip, making receiving of RMA faster by using barcode scanners Generate pre-paid UPS "returns" label The functionality needs to be the same a [login to view URL], but in a more attractive Web3.0 layout (layout, icons, etc...). It has to work on a subscription model and needs to be web-based (cloud). Looking forward to your bidding.
