However, without their own money at stake, employees often have less incentive to submit their expenses on-time, creating a persistent challenge for finance teams. Many cardholders delayed attaching receipts and completing expense details, leaving accountants with incomplete transactions that required manual follow-up. This increased administrative work and made it harder for finance teams to close their books on time at the end of each month. Without systematic reminders and an easy way to submit receipts, late expenses became a recurring problem, undermining finance teams' trust in credit cards as an expense management solution. Improving submission behavior required more than simplifying the process. It meant addressing how employees prioritized their responsibilities after making a payment. https://images.squarespace-cdn.com/content/v1/5acbdb1445776ec3a5f7fe9d/1794232547594-DD1Y914XIKHLR89N83YT/IESR+-+1.png Improving expense submission rates - The situation Credit cards make company spending more convenient for employees by removing the need to pay out of pocket.
