RPA for invoice processing, 1,200 vendor bills per month
UiPath bots with exception queue cut manual entry from four FTEs to one reviewer, audit trail for SOX.
- A listed logistics company processed ~1,200 vendor invoices monthly, PDF, email, portal downloads, into SAP with four FTEs doing line-by-line entry. SOX audit noted insufficient segregation of duties on manual edits and no immutable audit trail for invoice corrections.
- Simplileap process mining mapped variants: 14 invoice formats, three approval paths, duplicate vendor IDs in SAP master data, and an average 6.2-day cycle from receipt to posting. Leadership mandated straight-through processing above 75% within two quarters.
- Approach: UiPath bots built per stable format with Document Understanding fallback for semi-structured PDFs; exception queue with reason codes; bot pause on amount variance > 2% vs PO; immutable Orchestrator log export for auditors.
