Best receipt scanner for agencies

There are roughly 30-50 receipt scanning apps in active use (Expensify, Adobe Scan, Zoho Expense, etc.), but fewer than 10 actually solve for multi-client workflows that agencies need. The core pain points are brutal: most scanners don't handle batch uploads, lack client segregation, integrate poorly with agency accounting software (QuickBooks, Xero), or require manual categorization that kills your margins. Generic receipt tools treat all users the same, but agencies need role-based access, client billing codes, project tagging, and audit trails by client—features that existing solutions bolt on poorly. The real gap is in workflow integration: agencies need their scanner to sit between client submissions and accounting without creating friction. A new entrant should laser-focus on three things: (1) seamless integration with QuickBooks Online and Xero's client projects feature, (2) bulk upload with smart client auto-routing, and (3) audit compliance for client billing disputes. The market is growing—agency expense management is becoming a higher-margin service offering—but it's currently fragmented between generic expense apps and custom spreadsheet hell.
