The use case: how Octopus Energy deploys Rossum
Octopus Energy uses Rossum to automatically process supplier invoices, replacing a template-based OCR system. Rossum handles line-item GL coding, duplicate detection, approval routing, and syncing approved invoices to NetSuite, and the team also uses it for reporting on outstanding invoices and processing times.
