The normal Expensify flow is receipt, then SmartScan, then an expense report, then approval, then reimbursement or an accounting sync. The Card skips most of that chain for its own transactions. A charge posts, Expensify already knows the amount, the merchant, and the date, and under the IRS's own threshold for electronic records, it doesn't need a scanned receipt to back it up.
That changes who's floating the money, too. A card tied to the company means an employee isn't paying out of pocket and waiting to get reimbursed, and an admin sees spend the moment it happens instead of finding out when an expense report lands in their queue days or weeks later.
