What problem does it solve?
Every organization pays suppliers, and in many the invoice still arrives as a PDF or paper that someone keys into the ERP. Staff then chase purchase orders and goods receipts, code the cost centre and tax, and route the invoice to an approver who may take days to respond. Banks are no exception: their own procurement of technology, property and services runs through the same accounts payable process as any large company.
The costs are well documented. Manual handling is slow and expensive per invoice, late payment loses early payment discounts and damages supplier relationships, and duplicate payments and invoice fraud (a changed bank account on a fake invoice) cause direct losses. Template based OCR helped with the largest suppliers but breaks on the long tail of layouts.
- Ardent Partners' State of ePayables 2025 report puts the average cost of processing an invoice at USD 9.84 and finds that the teams it ranks as Best in Class (the 20% with the lowest cost and shortest cycle time) process invoices at a 79% lower cost and 79% faster than their peers.State of ePayables (Part Nine): AP Benchmarks and Best-in-Class Performance (2025)
How does it work?
- Capture. Invoices arrive by email, supplier portal, electronic invoicing network or scanned post. Structured electronic invoices are read directly; the rest go through AI extraction.
- Extract and validate. The AI extracts supplier, invoice number, dates, amounts, tax and line items, and validates them against the vendor master (tax ID, bank account, currency).
- Match. It performs two or three way matching against purchase order and goods receipt, within tolerances, and explains any mismatch in plain language.
- Code and check. For invoices without a purchase order it proposes the general ledger account, cost centre and tax code from history and contract terms, and checks for duplicates and fraud signals such as a changed bank account.
- Route, approve and post. Clean invoices post automatically within limits; others go to the right approver with a summary. Approvers can ask questions in chat or email, and every step is logged for audit.

How this is calculated
Formula: invoices * costPerInvoice * costReduction. The low scenario uses every low input, the high scenario every high input.
| Input | Low | High | Basis |
|---|---|---|---|
| Supplier invoices per year invoices, invoices per year | 300,000 | 300,000 | The reference organization. Replace with your own invoice volume. |
| Current fully loaded cost per invoice costPerInvoice, USD per invoice | 6 | 10 | Ardent Partners puts the average at USD 9.84 per invoice in its State of ePayables 2025 benchmarks; the low end is an editorial assumption for a team with some automation already in place. Source |
| Share of processing cost removed costReduction, fraction of cost per invoice | 0.3 | 0.6 | Editorial assumption, well below the 79% cost gap between the teams Ardent Partners ranks as Best in Class and their peers. |
What it leaves out: Processing cost only. It leaves out captured early payment discounts, avoided duplicate and fraudulent payments, and the cost of the platform, supplier onboarding and ERP integration.

Federal Deposit Insurance Corporation
United States · Government and public sector · 2024
The FDIC, the US bank deposit insurer and supervisor, is developing AI that extracts data from invoice and contract PDFs and reconciles them, emailing oversight managers a spreadsheet of discrepancies and errors. A separate initiative in its Division of Finance plans AI monitoring of invoices for proper submission and duplicate payments. Both are listed as in development or initiated in the 2024 federal inventory; no results are published.
No outcome disclosed.
U.S. Immigration and Customs Enforcement
United States · Government and public sector · 2019
Business units at ICE, part of the Department of Homeland Security, use an intelligent document processing platform (UiPath Suite and Azure AI Document Intelligence) with OCR and machine learning models to verify, extract and classify information from forms, automating repeatable work such as invoice processing and form entry validation. The agency lists it in operation since 2019 and says it saves staff significant time while improving data quality. No figures are published.
No outcome disclosed.
Veolia
France · Energy and utilities · 2022
A Veolia shared service centre that posts supplier invoices for 30 group entities rebuilt the process around central email inboxes, a UiPath robot built by InnovationPath and Rossum's AI data capture, while moving 60,000 suppliers to paperless invoicing. The most technically skilled of the former data entry clerks now review extractions and handle exceptions as "AI Associates"; output goes as a standard EDI message to each entity's ERP. The vendor reports an eightfold speed up in the AI Associates' processing.
- Productivity gain: up to 87.5%, processing time savings of the AI Associates
"So far, the AI Associates were able to speed up their processing by 8x, with time-savings efficiency reaching up to 87.5%."

Kingfisher
United Kingdom · Retail and ecommerce · 2021
Kingfisher's global business services centre in Poland, which handles accounts payable for six European countries (about 40,000 invoices a month), went live with Rossum's AI data capture in January 2021. Invoices arrive in central email inboxes; Rossum routes them by country and invoice type, extracts and validates the data, checks for duplicates and passes it to robots that index the invoices in SAP, where accountants still handle exceptions. The vendor reports that 60% of invoices now pass the data extraction step without any manual intervention before they reach SAP (it does not report an end to end touchless rate), that average indexing time fell from 5 minutes to 25 seconds, and that 14 full time employees moved to other invoice processing tasks.
- Handling time reduction: about 90%, time to index an invoice into SAP (from about 5 minutes to 25 seconds on average)
"Kingfisher's GBS cuts SAP invoice indexing time by 90% with end-to-end AP automation"
Claimed by: vendor - Productivity gain: 80%, manual data entry work of the accounts payable accountants, with 79% of invoice fields read automatically
"That means 80% less manual work for our accountants, so the team can focus on vendor queries, exceptions, and higher-value work instead of just typing data all day."

How do you implement it?
A model agnostic playbook: what to prepare, the order to build in, and what goes wrong.
Data you need
- Clean vendor master with tax IDs and verified bank accounts
- Purchase orders and goods receipts in the ERP for matched spend
- Historical coded invoices to learn coding for non purchase order spend
- Approval matrix and limits by entity, cost centre and amount
Systems to integrate
- ERP (accounts payable, purchasing, general ledger)
- Email inboxes, supplier portal and electronic invoicing networks
- Vendor master and supplier onboarding tools
- Payment and treasury systems
- Approval workflow and collaboration tools
Complexity: Medium
Extraction and matching are mature, off the shelf capabilities. The effort is in vendor master data quality, purchase order discipline, ERP integration and the approval rules.
- 1
Measure the baseline
Record cost per invoice, touchless rate, cycle time and exception reasons by supplier and entity. Most of the value case depends on where exceptions come from.
- 2
Fix the master data first
Duplicate suppliers, missing tax IDs and unverified bank accounts cause more exceptions than extraction errors. Clean them before tuning any model.
- 3
Start with extraction and matching
Automate capture and purchase order matching for the largest suppliers, measure field level accuracy, and keep people validating low confidence fields.
- 4
Add coding and fraud checks
Introduce proposed coding for non purchase order invoices and duplicate and bank account checks, with thresholds agreed with the controller.
- 5
Automate posting within limits
Allow touchless posting only for matched invoices under a value threshold from suppliers with verified details, and widen gradually as quality holds.
Guardrails
- Bank account changes are verified out of band before any payment, never from the invoice alone
- Segregation of duties and approval limits are enforced by the ERP, not by the model
- Duplicate checks run on every invoice before posting
- Low confidence fields always go to a person for validation
KPIs to instrument
- Touchless rate (invoices posted without manual intervention)
- Field level extraction accuracy on a weekly sample
- Cost per invoice and cycle time from receipt to approval
- Duplicate and fraudulent invoices caught before payment
- Early payment discounts captured
Human in the loop
Accounts payable staff validate low confidence extractions and resolve exceptions. Budget holders approve invoices according to the approval matrix, and the controller samples touchless postings every month.
Common failure modes
- Invoice fraud through changed bank details
- A fake or altered invoice redirects payment. Verify bank account changes through a separate channel and flag them automatically.
- Wrong coding at scale
- A learned coding pattern posts spend to the wrong cost centre for months. Sample coded invoices and review coding drift at every close.
- Automation that moves the queue
- Extraction improves but approvals remain slow, so cycle time does not change. Measure end to end, including approval time.
What are the risks and rules?
EU AI Act
Minimal risk
Processing supplier invoices is not an Annex III use case, is not a practice prohibited by Article 5 and does not involve decisions about natural persons, so it is minimal risk and the AI literacy duty of Article 4 applies. Approvers who ask questions in chat use an internal tool they know is AI; if that is not obvious to the people using it, the provider must also inform them that they are interacting with an AI system (Article 50(1)).
Rules that apply
Guidance
- VAT in the Digital Age (ViDA) (European Commission, Europe). The EU VAT package that lets Member States mandate electronic invoicing and, from 1 July 2030, requires digital reporting based on electronic invoices for cross border B2B supplies, which changes the capture step.
- AS 2201: An Audit of Internal Control Over Financial Reporting That Is Integrated with An Audit of Financial Statements (Public Company Accounting Oversight Board, North America). Applies to integrated audits of US public companies (issuers), not to every organization. In those audits, the auditor tests the controls over automated invoice processing like any other control over financial reporting.
- Digital Operational Resilience Act (Regulation (EU) 2022/2554), Article 28 (European Union, Europe). Relevant only when the deployer is a financial entity such as a bank or insurer. Its invoice capture platform and AI vendors are then ICT third party service providers, managed under the ICT third party risk principles of Article 28.
Controls to put in place
- Extraction and coding models inventoried with an owner and monitored for accuracy
- Full trail of extraction, validation, match, approval and posting per invoice
- Out of band verification of supplier bank account changes
- Monthly sample of touchless postings reviewed by the controller
Frequently asked questions
- What does it cost to process a supplier invoice?
- Ardent Partners' State of ePayables 2025 report puts the average at USD 9.84 per invoice, and the accounts payable teams it ranks as Best in Class process invoices at a 79% lower cost and 79% faster than their peers. Your own figure depends on the share of paper, purchase order coverage and approval discipline.
- What share of invoices can go through without a person?
- It varies with supplier mix, master data and purchase order coverage, and few sources report a true end to end touchless rate. In its Kingfisher customer story, Rossum reports that 60% of invoices pass data extraction with no manual intervention before they reach SAP. That covers the extraction step only: exceptions are still handled in SAP, and the story does not say what share of invoices is posted without a person.
- How do you stop AI from paying fraudulent invoices?
- Never let the invoice change where money goes. Verify supplier bank account changes out of band, run duplicate checks on every invoice, and keep segregation of duties and approval limits in the ERP rather than in the model.
