Send them a secure, shareable link to submit their expenses and receipts. No app download or account creation is required on their part. COMPLETE AUDIT TRAIL: Never wonder about the status of a payment again. A crucial, immutable history shows every approval, note, and status change for each expense, providing a vital tool for accountability.
