Connect With Blain Supply

TrueCommerce has several connection methods available. If you already connect via EDI with other Retailers, TrueCommerce can set up an AS2 connection (our preferred method), a VAN connection, or FTP/SFTP connection.

If you are not capable of electronic exchange of data, TrueCommerce has an alternative option to connect using their portal solution. It is a user-friendly web portal where most of the information is already populated from the PO; therefore, very little data entry is involved.
