    AI Back-Office Workflow Automation

    Turn Messy Invoices and POs Into a Review-Ready Workflow

    This custom-built workbench reads incoming invoices and supporting documents, extracts the key details, matches related records, and flags missing information or mismatches for human review. Staff get one organized queue instead of chasing attachments, spreadsheets, and email threads.

    Back-Office Workflow · Demonstration
    Anonymized invoice and purchase-order review workflow with fictional demonstration data
    Anonymized demonstration with fictional companies, invoices, amounts, and operational data.
    • Extract invoice and purchase-order details automatically
    • Match related documents and surface missing records
    • Flag pricing, quantity, freight, and documentation exceptions
    • Prepare clean, review-ready information for the existing business system
    • Keep staff in control of final review and approval

    An operator-grade workbench that sits beside the existing system of record.

    How it works

    1. 1

      Documents arrive

      Invoices, POs, and supporting attachments land in the inbox or shared folder.

    2. 2

      The workflow extracts and matches the details

      Key fields are pulled from each document and cross-referenced against related records.

    3. 3

      Exceptions are surfaced for review

      Anything missing, mismatched, or unusual is flagged with context — nothing slips silently.

    4. 4

      Staff approve and move clean information into the existing system

      A human always makes the final call. The workbench sits beside the system of record, never replacing it.
