Assuming you have the electronic billing add on and setup is completed the basic steps are

1. Client information must say that client should use electronic billing. I think it is on the Arrangement 2 tab

2. Generate bill and put in proof stage

3. Go to bills and choose to create the appropriate electronic bill

Thanks Caren.  Yes, I have done all of the above.  Now, the next step is to send the bills to the audit house.  However, some of my bills are not in the box to click to allow them to go up to the audit house?  I did 20 bills and 3 of them wont go to the audit house...  Ugh.

Are there error messages? Is the problem in creating the dat file or uploading? If uploading then there should be an error message or the audit house should be able to tell you what the issue is.
