I had a company-issued AMEX while at megacorp. Was allowed to use it for both business and personal charges. We were able to keep the FF miles/rewards that were generated from all the charges.
The company used an automated expense reporting system which was extremely convenient for the employee and a very powerful data analysis tool for the employer. Expense reports did not get approved (only disapproved later if caught via audit) so the reimbursements were made quickly after the report was entered via phone. That was 10 years ago so they may be using the internet now.
Several folks over the years were invited to pay back reminbursements and/or find another place to work based on issues with expense reports which were detected by the software or audits. There was a story of one sales guy who had a few too many $24.99 charges on his expense report. A receipt was not required for an expense under $25. He was invited to refund several thousand dollars in expenses or leave. He left.
