National Tenant Network - If your company is small, you may find it difficult to pull credit. Ask your applicants to provide that to you if you feel you need it. I don't always worry about credit, if they tell me they don't have good credit for instance, I don't bother.
National Tenant has a menu of reports and it is pay as you go after a set up. There is a credit "recommendation" report, but it does not give the detail on what they owe and to who. When I joined (many years back), set up was $50.00. I now pay about $30 per applicant for the reports I use.
I am not affiliated with them in any way.
I am sure you know this, but never skip the process of talking to the employer (NOT THE NUMBER THEY GIVE YOU) and prior landlords.
