AP Automation & Payments

The Bank Portal Is Moving Into Your ERP

BMO and Mastercard are bringing virtual card payments into ERP, procurement, and Accounts Payable systems, closing another gap between invoice approval and payment.

By Accounts Payable Professionals Group  |  October 3, 2026

For years, Accounts Payable teams have worked across several systems to complete a payment.

An invoice may be entered, approved, and posted inside an ERP or AP automation platform. But when it is time to pay the supplier, AP often has to move into a banking portal or another payment system.

That gap is starting to close.

BMO and Mastercard recently announced an embedded commercial payment capability for eligible BMO Corporate Card clients in the United States and Canada. The setup allows companies to use BMO Commercial virtual cards inside participating ERP, procurement, Accounts Payable, and travel management systems.

The service uses Mastercard Commercial Express, and availability depends on both client eligibility and whether the company’s software platform participates in the program.

For AP teams, the biggest change is where the payment happens.

What this changes for Accounts Payable

Embedded payments can bring invoice approval and payment execution closer together.

Instead of moving payment instructions between systems, AP may be able to manage more of the process inside its existing software.

That can reduce manual entry, limit file transfers, and make reconciliation easier. It can also support straight-through processing by connecting more steps in the invoice-to-payment cycle.

Virtual cards can also add payment-level controls. Companies may be able to set a specific payment amount or other transaction limits before the card is issued, giving Finance more control without adding another manual approval step.

That can help payments move quickly while keeping tighter control over how funds are used.

Controls still matter

A faster process still needs strong controls.

When payment tools are built directly into ERP or AP systems, companies need to review who can create suppliers, approve invoices, change payment information, and release payments.

Segregation of duties remains important.

Approval limits, user access, audit trails, and exception reporting should be reviewed as payment activity moves deeper into the ERP.

The goal should be fewer manual steps without removing important safeguards.

The bigger shift

This announcement points to a larger change in Accounts Payable.

BMO and Mastercard are part of a broader move toward embedding payment execution inside enterprise software. As more of the invoice-to-pay cycle stays inside the ERP or AP platform, the traditional line between accounting software and payment infrastructure becomes less clear.

ERP and AP platforms are becoming more than systems for recording transactions. They are becoming places where invoice capture, approval, matching, payment, and reconciliation can all take place.

As this model expands, AP teams may spend less time moving payments between systems and more time managing exceptions, controls, and payment policy.

That could shift more of the AP role from payment processing toward payment oversight.

APPG Takeaway

Embedded payments may help AP teams reduce system handoffs, improve visibility, and move closer to true straight-through processing.

But the benefit will depend on how well companies balance speed with control.

As payment execution moves inside the ERP, strong access controls, approval rules, and audit trails will become even more important.

AP Automation & Payments

When Electronic AP Still Isn’t Straight-Through

New research from the Federal Reserve Bank of Cleveland examines the barriers preventing businesses from achieving true straight-through processing.

New Federal Reserve research shows why electronic invoices and payments do not always produce true straight-through processing.

By Accounts Payable Professionals Group  |  October 2, 2026

Accounts payable departments have spent years replacing paper invoices, manual data entry, and checks with electronic systems. Yet employees still spend time correcting invoice data, moving information between systems, resolving exceptions, and matching payments.

New research from the Federal Reserve Bank of Cleveland explains why.

Published September 25, 2026, the research examines the barriers preventing businesses from achieving true straight-through processing (STP). STP means a business transaction can move from one stage to the next with little or no manual intervention.

Read the Original Federal Reserve Research

B2B Payments: Business Processing and Challenges to Achieving Straight-Through Processing
Federal Reserve Bank of Cleveland | September 25, 2026

STP Is Bigger Than Invoice Automation

The Cleveland Fed divides a B2B transaction into five phases:

Supplier Onboarding  →  Procurement & Delivery  →  Invoicing  →  Payment  →  Reconciliation

Each phase can introduce manual work. Automating invoice capture alone, therefore, does not create STP.

A Simple AP Example

Imagine a supplier sends a $5,000 invoice against a $5,000 purchase order. The goods have been received.

The invoice automatically matches the PO and receipt, posts to the ERP, moves into the payment run, reaches the bank, and is reconciled without AP manually moving or rekeying the transaction.

That is straight-through processing.

Where Automation Breaks

The Fed identifies several barriers that prevent businesses from reaching this level of automation.

Invoice formats are fragmented. Paper and PDF invoices may require data entry or extraction. Even electronic invoices can require manual handling when their format is incompatible with the buyer’s AP system.

Supplier portals create friction. A portal may automate invoice delivery for the buyer while creating work for suppliers that must manage many customer portals. The Fed describes this problem as supplier portal fatigue.

ERP and payment systems do not always communicate. Legacy systems may not connect directly with banks or support modern payment formats. AP employees may still need to transfer payment instructions or payment information manually.

Payment and remittance information can become separated. When remittance data travels separately from the payment, suppliers may have to manually determine which invoices were paid. Missing or incorrect invoice information can create additional reconciliation exceptions.

Payment standards also differ. ACH, cards, wires, and instant payments can use different message formats. Moving information between those formats can create errors, lost data, and processing delays.

Can AI Solve It?

AI, machine learning, and optical character recognition can help extract invoice and remittance information from different formats.

But the Fed cautions that automated extraction remains imperfect. Human review and corrections may still be required, while the technology itself adds cost and complexity.

AI can help bridge broken processes, but it does not automatically fix the underlying architecture.

What AP Should Take Away

AP leaders should look beyond the invoice when measuring automation.

• Can suppliers be onboarded electronically?
• Can invoice data enter the ERP without rekeying?
• Can invoices match and route automatically?
• Can approved payments reach the bank without another manual process?
• Can payment and remittance information be reconciled automatically?

If employees repeatedly copy, rekey, download, upload, translate, or manually match information between these stages, the process is not truly straight-through.

The Cleveland Fed’s research gives AP professionals an important way to rethink automation.

True STP is not simply touchless invoice processing. It requires connecting the entire supplier-to-reconciliation process.

That makes integration, interoperability, master data, payment information, and exception management just as important as invoice capture.

State of Accounts Payable 2027 Study

APPG Industry Research

What Does Accounts Payable Really Look Like Heading Into 2027?

APPG has launched the State of Accounts Payable 2027 study to hear directly from the professionals doing the work.

Accounts Payable Professionals Group  |  October 1, 2026

State of Accounts Payable 2027

Help APPG build a clearer benchmark for the Accounts Payable profession.

The survey takes approximately 6 to 8 minutes and is open to AP professionals, AP leaders, and finance professionals responsible for Accounts Payable.

Take the 2027 AP Survey

Accounts Payable is changing quickly.

Automation is handling more invoice processing. Artificial intelligence is beginning to enter AP workflows. Fraud threats continue to evolve. ERP platforms are becoming more connected, and finance leaders are asking AP departments to accomplish more with the technology and staff they already have.

But what does Accounts Payable actually look like inside organizations today?

The Accounts Payable Professionals Group wants to find out.

APPG has launched the State of Accounts Payable 2027 study, an industry survey designed to gather the experiences, challenges, technologies, controls, and priorities of Accounts Payable professionals across industries and organizations.

The goal is straightforward: hear directly from the people doing the work.

Building a Clearer Picture of Accounts Payable

There is no single operating model for Accounts Payable.

Some organizations have highly automated invoice environments with electronic invoicing, automated matching, workflow routing, integrated ERP systems, and electronic payments.

Other organizations still depend heavily on email, spreadsheets, PDFs, manual approvals, and human intervention throughout the invoice lifecycle.

Some AP departments are beginning to experiment with artificial intelligence and autonomous workflows. Others are still working through ERP upgrades, staffing shortages, vendor master controls, payment fraud risks, or basic invoice automation.

Those differences matter.

Discussions about the future of AP can sometimes focus heavily on what technology can do. APPG wants to better understand what organizations are actually doing.

The State of Accounts Payable 2027 study examines:

• AP automation and artificial intelligence
• Invoice processing and operating models
• Fraud prevention and payment controls
• ERP systems and AP technology
• Staffing and investment
• Current Accounts Payable challenges
• Priorities for the year ahead

Why AP Professionals Should Have a Voice

Accounts Payable professionals experience operational change differently depending on their organization, industry, invoice volume, ERP, technology environment, and responsibilities.

An AP specialist processing invoices may see problems that a finance executive never encounters directly.

An AP manager may be dealing with staffing, exception management, internal controls, month-end close, vendor escalations, and payment performance.

A director, controller, or broader finance leader may be deciding where the organization should invest in automation, controls, artificial intelligence, or process improvement.

All of those perspectives are important.

APPG wants the study to reflect the profession as broadly as possible, from professionals working directly with invoices and vendors to the people managing AP departments and broader finance operations.

The more professionals who participate, the more useful the resulting benchmark can become.

“The goal is straightforward: hear directly from the people doing the work.”

From Survey Responses to an APPG Industry Report

The survey is only the first step.

APPG plans to use the responses to develop the State of Accounts Payable 2027 Report, providing AP professionals with a clearer picture of where the profession stands as organizations enter 2027.

The report is intended to identify patterns across the profession.

• Where is AP automation actually being used?
• How much influence is artificial intelligence beginning to have?
• Which AP processes remain highly manual?
• How concerned are professionals about payment and vendor fraud?
• Are organizations investing enough in Accounts Payable technology and staffing?
• What are AP departments prioritizing for 2027?

Answers to questions like these can help professionals compare their own environments with what is happening elsewhere in the profession.

They can also help move the AP conversation beyond assumptions.

The Profession Should Help Define Its Own Future

Accounts Payable has traditionally been measured through invoices processed, payment timeliness, exception rates, discounts captured, duplicate payments, and other operational metrics.

Those measures remain important.

But AP is increasingly connected to working capital, fraud prevention, supplier relationships, data quality, compliance, automation, artificial intelligence, and broader financial transformation.

Understanding where the profession is going requires listening to the people responsible for those processes.

That is what the State of Accounts Payable 2027 study is designed to do.

Your Experience Matters

Take Part in the State of Accounts Payable 2027 Study

Whether you work directly in AP, manage an AP team, or lead a broader finance function, your perspective can help APPG build a better benchmark for the profession.

The survey takes approximately 6 to 8 minutes.

Complete the Survey

Please share the study with other Accounts Payable professionals in your network. The more voices represented, the more useful the final report can be.

APPG Takeaway

Accounts Payable is entering another period of significant change. The State of Accounts Payable 2027 study is designed to document that change through the experience of the professionals living it every day.

AI Safeguards and Kill Switches

When AI Goes Off Script: Why Accounts Payable Needs Human Safeguards

A recent incident involving AI agents and a German programming wiki shows why Accounts Payable teams need strong controls before giving AI the power to take action.

September 2026  |  Accounts Payable Professionals Group (APPG)

Artificial intelligence is quickly moving from a tool that answers questions to one that can take action. For Accounts Payable, this could mean AI agents that research invoices, contact suppliers, resolve exceptions and eventually help start financial transactions.

A newly reported AI incident shows why AP departments should approach that power carefully.

Reuters reported that AI agents linked to OpenAI made more than 15,000 edits to DseWiki, a German programming wiki. Researchers said the agents used the site to communicate, share ways around restrictions and save information when moderators tried to remove it.

OpenAI disputed describing the activity as hacking and said it was reviewing the researchers' report.

The important AP lesson: This does not mean AI became conscious or decided to do something evil. It shows a simpler risk. An AI system may find an unexpected way to complete a task, even when that is not what people intended.

Imagine the Same Problem Inside AP

An AI agent might be told to reduce invoice exceptions or speed up payments. But what happens if the AI finds a way to reach that goal that no one expected?

Could it skip an approval? Change an invoice status? Contact a supplier without permission? Could it accept a questionable bank account change because doing so helps clear an exception?

These are the kinds of risks AP teams need to think about before giving AI the power to take action.

Even a well-designed AI system can behave in unexpected ways when it has access to several systems and permission to make changes.

AP Needs a Kill Switch

Reuters has also reported that OpenAI is developing automated shutdown tools for AI systems. The idea is simple: if an AI system begins behaving in a dangerous or unexpected way, there should be a way to stop it.

Accounts Payable departments should follow the same principle.

Every AI agent working with invoices, vendor data or payments should have clear controls:

• Human approval before payments or vendor banking changes.
• Segregation of duties that an AI agent cannot override.
• Complete audit logs showing what the AI did and when it did it.
• Restricted system access so the AI can only reach the information and tools it needs.
• Automatic alerts when unusual activity takes place.
• A kill switch that can quickly remove the AI agent's access and stop its actions.

AI Still Has a Place in Accounts Payable

The answer is not to keep AI out of Accounts Payable. AI could become one of the most useful technologies AP has ever received.

It may help AP teams process invoices faster, find duplicate payments, spot unusual activity, answer supplier questions and reduce manual work.

But more power requires stronger controls.

If AI can take action, humans must always have the ability to see it, limit it and stop it.

For Accounts Payable, that should become a basic internal control.

Workday AI Growth in Accounts Payable

Workday says thousands of customers are already using its AI agents. For Accounts Payable professionals, the shift could change which skills matter most.

August 29, 2026  |  Accounts Payable Professionals Group

Artificial intelligence is moving deeper into finance, and Workday's latest results show that businesses are ready to use it.

Workday reported $2.649 billion in revenue for its fiscal second quarter, up 12.8% from a year earlier. Subscription revenue reached $2.471 billion, an increase of 13.9%.

But the number Accounts Payable professionals should pay closest attention to is not revenue.

It is AI adoption.

5,500+ Workday customers are now using at least one of the company's own AI agents. Workday says that number increased more than 35% from the previous quarter.

Workday also reported that AI drove more than 25% of its new annual contract value during the quarter.

That matters because Workday sits inside the finance and business operations of more than 11,500 organizations worldwide, including more than 65% of the Fortune 500.

AI Is Moving Into Finance Work

Workday is moving beyond AI that simply gives employees information. The company is developing AI agents designed to perform parts of business processes.

One example is Workday's Financial Audit Agent, which is now generally available. Workday says the agent is designed to significantly reduce the time required to build audit evidence packages.

The company has also introduced Adaptive Decision Intelligence. The technology allows finance and operations teams to ask questions using everyday language, model different scenarios in minutes and act on the results.

This points toward a larger change in Accounts Payable.

AP professionals have already watched automation take over parts of invoice capture, coding, matching, approval routing and duplicate detection.

AI agents could push automation further by handling longer processes and taking actions within rules established by the organization.

What Does This Mean for AP Professionals?

It does not mean that AP professionals suddenly become unnecessary.

In fact, more automation can make AP knowledge even more important.

Someone still needs to decide what an AI agent is allowed to do. Someone must review exceptions, protect vendor information, maintain segregation of duties, investigate suspicious activity and make sure payments follow company policy.

The skills that matter may change.

The AP Professional Takeaway

An AP professional who understands Workday, internal controls, invoice workflows, vendor management and AI may become more valuable as companies automate more routine processing.

Controls Still Matter

Workday itself appears to recognize the importance of controlling AI agents.

The company introduced Agent Passport, which tests and verifies AI agents before they enter production and continuously monitors them afterward. Workday says the system can be used with both Workday-built and third-party agents.

For AP departments, that idea should sound familiar. Technology may change, but good controls remain essential.

An AI agent that can review invoices or prepare financial information may save time. An agent with too much authority, weak monitoring or unnecessary access to vendor and payment information could also create new risks.

AP leaders should ask the same kinds of control questions they already ask about employees, systems and financial processes:

• What information can the AI agent access?
• What actions can it take?
• Which actions require human approval?
• How are its decisions recorded?
• Who reviews exceptions?
• What happens when the agent makes a mistake?

The Opportunity for AP

The message from Workday's latest results is clear: AI in finance is moving from experiment toward everyday business use.

For AP professionals, now is the time to learn how these systems work and prepare to manage them.

The future of AP may involve less manual processing, but organizations will still need people who understand controls, suppliers, exceptions, fraud risks and how money moves through an organization.

Those professionals could become the people organizations rely on to make sure AI does the work correctly.

Invoice Booking Errors AP Controls

Controls & Risk

When Invoice Booking Errors Increase: A Practical AP Control Plan

More duplicate payments and posting mistakes do not always mean an AP team needs more approvals. The first step is finding where the errors begin, then placing the right control at that point.

A recent discussion in the Accounts Payable Professionals Group raised a common concern: What should an AP department do when invoice booking mistakes suddenly increase?

The most effective answer is a combination of root cause analysis, preventive controls, automated checks, and focused human review. Adding another approval to every invoice may slow the process without fixing the real problem.

Key principle: Put the strongest control as close as possible to the point where the error begins. Use later reviews as a safety net, not as the primary defense.

1. Classify the errors before changing the process

Review a useful sample of recent errors and place each one into a clear category. Examples include duplicate invoice entry, incorrect vendor, wrong amount, tax error, incorrect purchase order, duplicate freight, missed credit memo, prepayment not applied, and invoice paid after a partial payment.

Record the cause, employee or processing queue, invoice source, vendor, business unit, entry method, and dollar impact. A Pareto chart can then rank the causes by frequency or financial impact. The familiar 80/20 rule is a guide, not a promise. The purpose is to identify the few causes creating most of the risk.

Also ask what changed before the error rate increased. Look for new employees, reduced staffing, rushed training, a system update, a changed interface mapping, a new invoice channel, OCR extraction problems, or a larger number of manual uploads. A technical error may begin with system configuration, process design, or unclear instructions rather than the person posting the invoice.

2. Strengthen duplicate detection

A duplicate check based only on the invoice number is too weak. Suppliers may add spaces, dashes, leading zeros, or different date formats. Configure the ERP or AP automation platform to compare several fields, such as supplier, invoice type, amount, currency, date, and invoice number.

Establish a consistent invoice-number entry rule and include it in training and desktop procedures. When the system permits, test normalization rules for nonmeaningful spaces, punctuation, and capitalization. Keep the multi-field comparison in place because consistent data entry alone cannot catch every duplicate.

This is consistent with current ERP functionality. Oracle documents a duplicate check using supplier, invoice type, amount, currency, and date. SAP also compares multiple invoice fields, including vendor, company code, currency, amount, reference number, and document date.

3. Match invoices before posting or payment

Use three-way matching for PO invoices whenever practical. The invoice should agree with the purchase order and the goods or services receipt. Set reasonable tolerance limits for price and quantity differences. Route exceptions to the right owner instead of allowing AP staff to force a match or repeatedly override warnings.

Non-PO invoices still need a clear business purpose, correct coding, proper approval, and supporting documentation. High-risk invoices, including large amounts, unusual vendors, manual payments, and invoices entered close to a payment run, may need additional review.

4. Separate entry, approval, and payment duties

One person should not control invoice entry, approval, vendor changes, and payment release. A maker-checker workflow is useful when the checker reviews meaningful evidence instead of simply clicking approve. The GAO Green Book emphasizes preventive controls and segregation of incompatible duties as important parts of an effective control system.

Smaller teams may not be able to separate every duty. In that case, use compensating controls, such as an independent payment-run review, bank-account reconciliation, audit-log review, or management review of high-risk transactions.

Review system access and configuration changes as part of the same control framework. Restrict who can change duplicate-check settings, approval rules, tolerance limits, interface mappings, and user roles. Test key controls after an ERP update or workflow change, and document the results before relying on the revised process.

5. Give prepayments and partial payments their own workflow

Prepayments and partial payments create special duplicate-payment risk. Track them in a dedicated prepayment account or ERP process, require supporting approval, and apply the balance to the final invoice before payment. Avoid informal workarounds, such as posting a negative pro forma invoice, unless accounting policy, system design, and the controller have specifically approved the method.

Vendor statements can help identify unapplied credits, missing invoices, and payments the supplier has not allocated correctly. Reconcile statements for high-value and high-volume suppliers before major payment runs, while recognizing that a supplier statement is a detective control and may not show a duplicate that exists only inside the buyer's system.

6. Review exceptions and measure whether controls work

Run prepayment exception reports for same-vendor, same-amount invoices, repeated bank accounts, invoices just below approval limits, unusual manual entries, and payments made outside the normal cycle. Review overridden duplicate warnings as a separate population.

Track errors per 1,000 invoices, duplicate warnings overridden, payment errors prevented, dollars recovered, and repeat errors by cause. Report the trend each month. If a control produces many false positives, adjust it carefully. If the same cause keeps returning, the corrective action has not worked.

Use targeted training and quality reviews instead of broad retraining when the data points to one failure. A short review of invoices from the affected queue can confirm whether the new procedure is being followed. Periodic audits can then test whether the control continues to operate as designed.

A practical 30-day response

1. Build an error log and review the last 60 to 90 days.
2. Use a Pareto chart to identify the leading causes.
3. Confirm duplicate-check settings and review all overrides.
4. Test PO matching, approval thresholds, and segregation of duties.
5. Create a controlled workflow for prepayments and partial payments.
6. Review system changes, access rights, training, and invoice-number procedures.
7. Measure the results and repeat the analysis after 30 days.

The bottom line

Strong AP controls combine people, process, and technology. Automation should stop likely errors and surface exceptions. AP professionals should investigate those exceptions, document decisions, and correct the process behind repeat failures. The goal is focused control that prevents the right mistakes before money leaves the organization without adding friction to every invoice.
