Revisions to Custom ASP Backend

Feel free to contact us for additional information before providing quote because it is difficult to explain the complete project since it involves a custom backend written in ASP hosted on a windows cloud server. Always have work that needs done if the project goes well. 1) In the address field expand character limit per field and allow foreign characters and special characters.

That file is accessible by th admin and shipper for download. Often sellers want invoices included with the order and up to now they email them to me and it is a nuisance. Would be great if it is all stored and accessible in the backend.
