Procure-to-Pay Challenges in 2026 [and How to Overcome Them]

According to the 2026 AFP Payments Fraud and Control Survey Report, 76% of US organizations experienced attempted or actual payment fraud in 2025. Widespread fraud is only one consequence of a broader problem: procure-to-pay (P2P) processes that span too many systems, teams, and handoff points without shared visibility or consistent controls.

This article covers 8 procure-to-pay challenges affecting organizations in 2026, explaining where each one originates, what causes it, and what it takes to fix it.

Key Takeaways:

• P2P challenges are connected, not isolated: A data quality failure at supplier onboarding creates invoice exceptions, payment errors, and fraud exposure downstream. Fixing symptoms without addressing root causes means the same problems return.
• Most P2P failures trace back to three root causes: Inaccurate data, unclear ownership, and disconnected systems create the conditions for every challenge on this list. Automation helps but doesn’t fix any of them on its own.
• The highest-cost problems sit at payment and recovery: Duplicate payments, overpayments, and supplier fraud are the most financially damaging P2P failures and the least visible until a structured audit surfaces them.
• apexanalytix strengthens the supplier-facing controls that determine P2P accuracy: Supplier data validation, payment fraud prevention, risk monitoring, and AP recovery audit address the root causes of P2P failure rather than managing their downstream effects.

What Are Procure-to-Pay Challenges and Why Do They Persist?

Procure-to-pay challenges are process, data, and control failures that prevent an organization from moving efficiently from identifying a need and making a purchase request to paying the supplier’s invoice.

These challenges persist because P2P spans procurement, finance, AP, compliance, and supplier management, each with different systems, priorities, and definitions of success. A problem that starts in procurement often doesn’t surface until it reaches AP, by which point it has already affected invoice processing, approvals, and payment accuracy.

The result is that organizations treat P2P challenges as departmental problems rather than connected process failures, and each team addresses its own piece without a shared view of where the underlying failure started.

Procure-to-Pay Challenges Overview

The table below summarizes all eight challenges in terms of their root causes, their point of appearance in the process, and their primary impact.

8 Key Procure-to-Pay Challenges and Solutions

The challenges below follow the P2P process from supplier setup through audit and recovery.

1. Fragmented workflows and limited visibility

In large enterprises, P2P often doesn’t operate as a single connected process. Instead, procurement works in sourcing platforms, AP works in ERP modules, and finance works in reporting tools. Each system captures a piece of the process, but none share a complete picture.

Fragmentation is most damaging at handoff points. When a PO moves from procurement to AP, supplier data often doesn’t travel with it. When an invoice is flagged for exception, the approval team may not have visibility into the original PO or the supplier’s compliance status.

Incremental system additions, mergers, and acquisitions introduce additional ERPs, supplier databases, and approval workflows that were never fully integrated. Problems that could be caught early compound quietly until they surface as audit findings or supplier disputes.

How to overcome it:

• Have a single verified supplier record that connects procurement, AP, and finance, rather than each function maintaining its own version.
• Centralize and validate supplier data management across ERP environments so every team works from the same starting point.
• Define clear ownership for each P2P handoff so problems don’t fall between functions undetected.

2. Inaccurate supplier data and slow onboarding

Supplier data enters the ERP at onboarding and often stays unchanged for the life of the relationship. When that data is incomplete, unverified, or duplicated, it creates downstream failures that are difficult to trace back to their origin.

This challenge starts at supplier setup and affects every stage that follows:

• An incorrect tax ID creates a compliance gap.
• An unverified bank account creates payment fraud exposure.
• A duplicate supplier record splits payment history and inflates the vendor count.
• A missing certification creates an audit finding.

Poor data quality at onboarding is one of the most preventable sources of downstream P2P cost, yet most of its impact spreads across invoice processing, payment controls, and audit findings rather than appearing as a single visible line item.

How to overcome it:

• Validate supplier data against authoritative external sources at the point of entry.
• Automate validation of tax IDs, bank accounts, legal entity names, and sanctions status before any supplier record is activated.
• Address common supplier onboarding challenges early to prevent them from compounding across the full P2P cycle.

3. Low purchase order compliance and invoice exceptions

Low PO compliance and high invoice exception rates are two sides of the same problem. When buyers purchase outside approved channels or from unapproved suppliers, invoices arrive without matching POs. AP teams must then resolve those exceptions manually before payment can proceed.

PO compliance falls when approved supplier lists are incomplete, procurement channels are too difficult to use, or there’s no enforcement mechanism at the point of purchase. Buyers take the path of least resistance, which is often an unapproved supplier or a verbal commitment that never generates a PO.

Every unmatched invoice requires manual intervention. That work costs more, takes longer, and introduces errors that compound downstream. High exception rates are one of the clearest signals that PO compliance is failing earlier in the process.

How to overcome it:

• Close gaps in preferred supplier coverage by category, so buyers always have an approved option.
• Simplify the requisition process so the approved path is faster than workarounds.
• Use a structured vendor risk management checklist to identify where supplier coverage and compliance controls need strengthening.

4. Manual approvals and delayed payments

In many enterprises, invoice approvals still move through email chains, shared inboxes, or paper-based routing. Each step introduces delays, and the longer an invoice waits for approval, the more likely it is to miss payment terms, generate late fees, or lose an early payment discount.

Approval workflows are often designed around organizational hierarchy rather than invoice priority. High-value invoices with early payment discounts wait in the same queue as routine payments, and no one is accountable for clearing the queue quickly.

According to the Atradius 2025 Payment Practices Barometer, 43% of credit-based B2B sales in the US were overdue in 2025, primarily driven by customer cash flow pressures. Late payments damage supplier relationships, trigger penalty clauses, and eliminate early payment discount opportunities.

How to overcome it:

• Automate approval routing based on invoice value, category, and urgency.
• Create a separate fast track for discount-eligible invoices.
• Remove email from the approval process and replace it with structured workflows that escalate automatically when approvals are overdue.

5. Duplicate invoices and overpayments

Standard ERP three-way match catches exact duplicates but misses near-duplicates with slightly different invoice numbers, amounts, or dates. Overpayments occur when invoices are paid at incorrect amounts due to pricing discrepancies, billing errors, or payments against cancelled orders.

Both issues appear at the invoice processing and payment stage, even though they originate earlier. Duplicate supplier records, inconsistent invoice coding, and multi-ERP environments all create the conditions that allow duplicates and overpayments to pass through undetected.

Duplicate payments and overpayments represent direct financial losses that accumulate quietly between audit cycles. The longer they go undetected, the harder they become to recover as supplier contacts change and accounting periods close.

To overcome it:

• Implement AI-driven duplicate detection that identifies near-duplicates beyond exact matches.
• Run structured AP recovery audits to recover payments that have already left the organization.
• Feed root cause findings from each audit cycle back into upstream controls to prevent the same errors from recurring.

6. Supplier fraud and unauthorized payment changes

Supplier fraud targets the trust that exists once a supplier relationship is established. A fraudster doesn’t need to breach your systems to redirect a payment. They only need to pose as the supplier and submit a convincing bank account change request.

This challenge appears at two points: supplier setup, where unverified bank account details enter the system, and the payment stage, where unauthorized change requests are processed without ownership validation. Most organizations rely on email or phone to handle those requests, and both channels are vulnerable to payment frauds like vendor impersonation and business email compromise.

Once a fraudulent payment leaves the organization, recovery is difficult. Misdirected payments often can’t be reversed quickly, and the operational effort of identifying and resolving fraudulent transactions adds cost beyond the original financial loss.

How to overcome it:

• Remove email and phone from bank account change processes entirely.
• Require verification of current account information before any new account can be submitted.
• Validate bank account ownership against banking authority data before any payment is released.
• Apply payment fraud prevention controls at the point of change request rather than after payment has left the organization.

7. Weak controls across decentralized operations

Large enterprises operating across multiple business units, regions, and ERP systems often apply P2P controls inconsistently. What one business unit enforces strictly, another handles manually. The result is a compliance patchwork where the weakest link determines the overall risk exposure.

This challenge is most visible in supplier onboarding, invoice approval, and payment controls. A supplier approved in one region may not meet the compliance standards of another. Decentralized operations create local ownership of P2P processes without enterprise-wide standards, and each business unit optimizes for its own efficiency rather than consistent control.

Organizations that grew through acquisition carry the highest exposure because legacy processes from acquired businesses are rarely rationalized into a consistent P2P framework before becoming active.

How to overcome it:

• Establish enterprise-wide standards for supplier onboarding, PO compliance, invoice approval, and payment controls.
• Enforce those standards through configurable workflows rather than policy documents.
• Apply supplier lifecycle management consistently across regions and business units from the first supplier contact through every transaction.

8. Poor performance measurement and accountability

Most organizations track P2P performance by function rather than by process. AP tracks invoice cycle time, procurement tracks savings, and finance tracks payment accuracy. None of these metrics tells you how the full P2P process is performing or where the handoffs between functions are breaking down.

This challenge is at the reporting and recovery stage, but its consequences affect the entire process. Without connected performance measurement, the root causes of P2P failures stay hidden across audit cycles.

AP teams optimize for faster invoice processing while the data quality failures driving their exception rates go unaddressed upstream. Recovery audits surface financial losses without connecting them to the control gaps that allowed them to accumulate.

How to overcome it:

• Track KPIs and risk indicators across the full P2P process rather than by function.
• Connect supplier data quality metrics to invoice exception rates, payment accuracy, and recovery value.
• Report P2P performance to shared leadership so improvement decisions address root causes rather than departmental symptoms.

How to Prioritize Procure-to-Pay Improvements

Not every P2P challenge deserves equal attention at the same time. Prioritization depends on where your organization loses the most money, time, or control.

A useful starting point is to work backward from financial impact. Here’s a general plan:

• Start with payment controls and recovery: Duplicate payments, overpayments, and supplier fraud represent the most direct financial losses. These are also the challenges where structured controls and recovery programs deliver measurable results quickly.
• Fix supplier data before automating anything else: Automation applied to inaccurate data produces faster errors. Cleaning and validating the vendor master before expanding automation prevents those errors from scaling.
• Address visibility gaps next: Without a connected view of the P2P process, improvement efforts in one function create unintended consequences in another. Shared data and cross-functional reporting create the foundation for sustainable improvement.
• Consider compliance and performance measurement last, but don’t treat them as optional: PO compliance, supplier compliance rate, and cross-functional KPIs aren’t urgent in the way payment fraud is, but skipping them lets root causes resurface after each improvement cycle.

How apexanalytix Strengthens P2P Controls and Visibility

P2P performance depends on the accuracy of supplier data and the strength of controls at every stage where that data affects a financial outcome. apexanalytix connects to existing ERP and procurement systems to validate supplier data, prevent payment fraud, monitor risk continuously, and recover financial losses that standard controls missed.

apexanalytix isn’t an ERP or procurement suite replacement. It covers the supplier-facing controls that existing systems leave exposed by: 

• Validating every supplier record against 1,200+ trusted data sources before it reaches the ERP
• Verifying bank account ownership against banking authority data before any payment change is processed
• Monitoring financial health, cyber posture, sanctions exposure, and ESG compliance continuously across the full supplier base
• Identifying duplicate payments, overpayments, and missed credits through AI-driven disbursement analysis and structured supplier outreach
• Connecting supplier data quality, compliance status, payment accuracy, and recovery value in one view across procurement and finance

Here’s what results look like:

• A global financial services firm managing 6,000+ vendors cut supplier onboarding from 45 days to 4 after replacing a manual risk survey with automated data collection and risk scoring.
• A global manufacturer processing $6 billion in annual spend recovered more than $2.5 million in duplicate payments, unapplied credits, and pricing discrepancies after implementing a structured AP recovery audit and statement review.

For organizations managing hundreds of suppliers across multiple ERPs and regions, these outcomes reflect what becomes possible when supplier data, payment controls, and recovery audit connect in one program.

FAQ

1. What is the difference between a P2P challenge and an AP problem?

AP problems are a subset of P2P challenges. Invoice exceptions and duplicate payments show up in AP, but their root causes typically originate earlier in supplier data quality, PO compliance, or approval workflow design.

2. Why do P2P challenges persist even after automation is implemented?

Automation moves data through the process faster, but it doesn’t correct it. If supplier records are inaccurate or approval ownership is unclear, automating the workflow around them just gets the same problems to their outcome sooner. Data quality and process ownership have to be fixed first. 

3. Which P2P challenge is the hardest to detect?

Supplier fraud and overpayments, as they both pass cleanly through standard AP systems without triggering exceptions. They require dedicated controls and structured audit programs to surface what a three-way match can’t catch.
