Use Cases

See it in action

How operators around the world can use this extension to solve real problems and grow their business.

Session ends, SAP B1 invoice posted automatically

A driver charges at an enterprise depot. Session ends. OASIS HUB generates the CDR and posts an A/R invoice to SAP B1 via Service Layer within 60 seconds. Finance team sees the invoice in SAP immediately.

Multi-country fleet operator

A fleet operator with chargers across 5 countries uses SAP B1 as their global ERP. OASIS HUB posts invoices to the correct SAP company database per country — fully automated, zero manual entry.

Enterprise CPO with existing SAP B1

An enterprise CPO already running SAP B1 for their business enables the extension. All new CDRs automatically create invoices in SAP B1 — no changes to existing SAP setup required.

Simulated Case Study

Enterprise CPO eliminates manual SAP B1 invoice entry for 500+ daily charging sessions

An enterprise CPO with 200 charge points was manually entering charging invoices into SAP B1 — a process taking 4 hours per day across two finance staff. After enabling the SAP Business One ERP extension, all invoices are posted automatically via Service Layer. The finance team now reviews exceptions only. Invoice accuracy improved from 91% to 99.8%.
