Step 8: Background Check (if necessary)

As part of our requirements for vendors/contractors that work within any of our service lines that have access to client funds and/or financial information, contractors/vendors will be required to complete a background check. Background checks will be conducted as permitted by local laws and regulations. Background checks are conducted via Checkr, a third-party background check provider.

Please note: Job assignments to contractors/vendors that work within any of our service lines that have access to client funds and/or financial information are contingent upon the Company’s satisfactory verification and clearance of the criminal background check and completed vendor portal setup.

If you need assistance with any of the above steps or using the Vendor Portal in general, please contact vendorsupport@flatfeecorp.com for help.
