As for payment, from experience, I typically see money in my account about 10-15 days after submitting my stuff to them.
They have a very good alternative for those that process more than 26 repairs in a monthly cycle, defining this more is below:
If you have a PC or Mac (Mac that has been bootcamp/partitioned & you've installed windows on your partitioned non-mac side)
You can get their software called Manager, this software is $239.99 + $24.95 per month (unless they give you the hookup

This would cost you 44.95 a month by breaking down the cost of the software and the monthly fee(keep in mind the software will cost you upfront), plus your per trans of $0.99. Again, i would only recommend this if you consistently submit over 26 repairs monthly.
Also, for those that use data tranz as a fax method and pay the $2.49 you don't have to submit the invoices via fax, you can use your computer or mobile device, i.e. mobile phone, ipad, tablet, etc.... paperedidotcom (if I'm not allowed to put that up, my apologies to the moderators). Just figured I would mention that, this will save you some time, and faxing kinda sucks sometimes, unless you fax via email anyway....
Just FYI, her name is Lana and the other person there should be Josh, these are the 2 main people I've delt with over the years.
