PRECISE, ROLE-BASED PERMISSIONS: Delegate with confidence by inviting members as Admins (full control), Reviewers (manage specific budgets), or Submitters (submit expenses).

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. AI-POWERED RECEIPT SCANNING: Snap a photo of a receipt, and let Keystone's AI automatically extract line-item details and totals. This minimizes manual data entry and saves everyone time.
