Responsibility of the County
It is the county’s responsibility to pay their BTA in full each month in a timely manner. If there are reconciliation issues, it is the responsibility of the county to assemble the details and make adjustments with American Express and/or CALtravelstore. These issues should be identified, communicated, and adjusted as soon as they are discovered.
You will have access to two different reporting systems to assist you with reconciliation of your account, American Express @Work and the iBank reporting system. Enrollment in iBank is automatic for your department when you create your account with CALtravelstore. Enrollment in American Express @Work will be completed with your American Express BTA application.
