From manual invoice entry
to autonomous SAP automation

SaltPay managed thousands of vendor invoices manually after transitioning to SAP — with no integration support. A Nanonets agent now extracts, validates, and posts invoices directly to SAP AP end-to-end.

The Problem

SaltPay transitioned to SAP's ERP system to serve their expanding client base, but their existing document processing provider didn't support SAP integration. Managing thousands of invoices manually was untenable as the vendor base grew.

  • No SAP integration — existing provider couldn't connect to their ERP system.
  • Template-agnostic AI required — 100K+ vendors means thousands of unique invoice formats.
  • Manual processing at scale was unsustainable — AP team spent hours on data entry.

Nanonets is like magic. I can't imagine how I would do invoice extraction without it.

The solution

One AI layer. Full SAP automation.

Nanonets replaced the manual loop with one autonomous agent. The agent captures invoices from email and portal, extracts all fields using template-agnostic AI, applies SaltPay's business rules, routes for team review, and posts directly to SAP AP — with no manual data entry required.
