You need to open the EFT file that contains the banking information of your company, the Sage 50 data file location and also the number system for payables, receivables, employees, (such as 200 for payables, etc) and that is where your company name should be showing.  If you cannot find this section then call the RBC Express tech support (not the bank) and they will likely be able to help you find the location to enter the company name. If you were the one to first set up RBC Express then this would have been the first section you would have needed to complete prior to entering vender names/bank info. Sorry I can't be more specific - it has been quite a while since I have used the RBC Express system but do remember it worked very well and the selling feature for me was the turnover time to get money fast to employees - do in morning and quite often it would be in employee bank by late afternoon same day.
