What software automates invoice processing and approval workflows?

Several software platforms automate **invoice processing** and **approval workflows**, including **Rillion**, **AvidXchange**, **Corcentric Cor360**, **HighRadius**, **Stampli**, **Payhawk**, **ProcureDesk**, **Adobe Acrobat**, **Bill.com**, **Basware**, **Medius**, and **Oracle NetSuite**.[1][2][3][4][5][6][7][8][9]

Common capabilities across these tools include:

- **Auto-routing invoices** to the right approver based on rules, roles, or AI.[1][3][6][7]

- **OCR/data capture** to reduce manual entry and processing errors.[2][7][9]

- **Three-way matching** against purchase orders and receipts.[1][2][5][7]

- **Exception handling** and discrepancy flags before approval.[4][5][7]

- **ERP/accounting integrations** to move approved invoices into payment and reconciliation workflows.[3][7][9]

If you want, I can narrow this down by **company size** (SMB vs enterprise), **industry**, or **best value**.
