## 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.

Summary written by usedby from the source page, in English. The figures are those of Rossum and Octopus Energy, not ours.

> As an Ofgem-regulated business, paying our critical suppliers late is simply not an option. Within nine days of going live, 85% of those invoices were being processed automatically.

- **50%**: “50% of AP team promoted: team members moved on to other parts of Octopus Finance or promoted into higher-skilled accounting roles.”

> My team love it because it’s very easy to use. I have people with very different skill sets — some are very tech savvy, some are not — and everyone finds it easy to use.

> Tracey Prince, Finance Transactional Manager
