Common AP automation challenges and solutions in 2026

Automating accounts payable is now a baseline expectation for finance teams under pressure to do more with less. But while the benefits of AP automation are clear (faster processing, better control over cash flow, and fewer AP errors), the process of adapting to full automation is rarely smooth.

From integration gaps and data quality issues to internal resistance and rising fraud risks, the challenges can stall even the most promising projects. That’s why successful AP automation is about anticipating obstacles and building the right foundation to overcome them.

Let’s walk through common AP automation challenges businesses are facing in 2025, why they happen, and how to solve them.

6 common challenges in AP automation and how to solve them

Automating accounts payable isn’t just a matter of installing new software. It’s a process change that touches finance, operations, IT, and even procurement. While the benefits are clear—efficiency, control, cost savings—the challenges are often underestimated.

Here are six of the most common roadblocks to successful AP automation, and what it really takes to address them.

1. Integration with legacy and disconnected systems

One of the most complex hurdles in AP automation is getting your new solution to play nicely with your existing tech stack. Most finance teams rely on ERPs or accounting platforms that were never designed with modern APIs or real-time connectivity in mind. Legacy systems often use rigid data structures, require manual file uploads, or operate in batch processes—none of which align with the real-time, interconnected nature of AP automation.

These gaps create major roadblocks. Teams are forced to build fragile workarounds, deal with data inconsistencies, or revert to manual reconciliation—defeating the purpose of automation in the first place.

How to solve integration challenges:

Start by identifying where your data currently lives and how it moves between systems. Prioritize AP tools with robust, well-documented APIs and pre-built integrations for your ERP or accounting software. If direct connections aren't feasible, middleware platforms can act as a translator between old and new systems. Just as important, involve your IT and finance teams early to assess compatibility and ensure your implementation is grounded in technical feasibility—not just vendor promises.

2. Implementation challenges

Even the most powerful AP tool can become a liability if the implementation is rushed, under-resourced, or poorly scoped. Many organizations underestimate the internal coordination required to roll out automation. Finance teams already juggling day-to-day operations often can’t absorb the extra workload. Meanwhile, unclear project ownership and shifting priorities delay progress and diminish confidence in the initiative.

Implementation delays don’t just waste time—they risk undermining adoption and trust before the system even goes live.

How to solve implementation challenges:

Treat implementation like a business-critical project, not a side task. Assign a dedicated project owner with decision-making authority. Build in extra capacity by backfilling team responsibilities or temporarily scaling back other initiatives.

Most importantly, narrow your scope. Start with one AP process, vendor type, or business unit as a pilot. Test the system, measure results, and use the success as leverage to expand.

A phased approach helps build buy-in while minimizing operational risk:

1. Start with a focused pilot—automate one department or process to test the solution
2. Define clear success metrics before you begin
3. Secure dedicated team members and outside experts to keep your project moving
4. Create a detailed implementation roadmap with realistic milestones to track progress

3. Data accuracy and integrity

A common myth is that automation fixes data problems by default. In reality, it simply moves data faster—meaning bad inputs create even bigger issues downstream. Invoices with incomplete line items, inconsistent formatting, or poor OCR scan results can throw off your GL coding, delay approvals, and trigger payment errors.

Worse, if your automation tool integrates with your accounting system, those errors can propagate across your financial reports and compliance processes in real time.

How to solve data integrity challenges:

To protect your data:

• Create multi-layered validation rules to catch problems before they enter your system
• Compare source documents against records regularly to spot error patterns
• Set clear data governance policies for AP, with defined ownership and correction steps
• Work with your vendors to standardize invoice formats and improve document templates for better OCR accuracy

4. Lack of visibility and control

AP automation can introduce speed—but if you're not careful, it can also create blind spots. Teams often complain that once invoices enter the system, they “disappear” into automated workflows with little visibility into where they stand. When approvals stall or exceptions arise, it becomes difficult to trace the issue. Without granular insight, finance leaders can’t answer simple questions like: Why was this invoice delayed? Who’s holding it up? Did we miss an early payment discount?

Lack of visibility not only weakens audit readiness—it reduces operational control, leading to slower decision-making and missed opportunities.

How to solve visibility and control challenges:

Choose an AP solution that surfaces real-time metrics, approval statuses, and exception workflows in a clear dashboard. You should be able to drill into invoice history, see who touched it, and understand why it’s flagged—all in a few clicks.

Implement user permissions that align with roles so that approvers only see what they need, but finance has full visibility. Set up automated alerts when invoices sit idle or when actions deviate from policy. Visibility should increase with automation—not decrease.

The best AP automation tools give you both efficiency and oversight.

5. Fraud and security risks

The speed and scale of AP automation can be a double-edged sword. While automation reduces manual touchpoints, it also removes the human “gut check” that sometimes spots suspicious activity. AP fraud—whether through business email compromise, fake vendor setup, or invoice manipulation—can slip through if proper controls aren’t in place. The irrevocable nature of certain payment methods (like real-time payments or wires) makes losses harder to recover.

Automation doesn’t reduce the need for oversight—it just changes how and where it needs to happen.

How to solve fraud and security risk challenges:

To strengthen your security:

• Require multi-factor authentication for users who can approve payments
• Set approval thresholds that trigger extra verification for unusual or high-value payments
• Test your technical and process vulnerabilities with regular security audits
• Design approval workflows with separated duties, so no single person has too much control
• Use AI-powered fraud detection tools that flag suspicious patterns early

6. Resistance to change

People—not technology—are often the biggest barrier to successful AP automation. Longtime team members may feel threatened by new systems, fearing job loss or loss of control. Others may default to old habits, circumventing the software with emails or spreadsheets. Executives may also underestimate the emotional and procedural shift required, assuming the tool will “just work” out of the box.

Without buy-in, even the best system fails to deliver value.

How to solve resistance challenges:

Start by communicating clearly: automation isn’t about replacing people—it’s about removing the repetitive tasks that slow them down.

Moreover:

• Be open about how roles will change—not disappear.
• Include key stakeholders in planning to gather feedback and build buy-in.
• Provide thorough, role-based training and ongoing support.
• Highlight early successes and recognize team members who embrace the new process to maintain momentum

By addressing these common challenges directly, you'll improve your chances of a successful AP automation rollout. Consider which issues matter most to your organization based on your current systems, team dynamics, and business needs, and adjust your strategies accordingly.

How to choose the right AP automation provider

Selecting the right AP automation provider is crucial for successful implementation, high user adoption, and lasting value. The best partner will fit your business needs and adapt as your processes change.

When comparing providers, focus on these key areas:

• Cost structure: Compare subscription-based pricing with upfront investment. Look beyond license fees to consider implementation, support, and user/transaction costs.
• Integration capabilities: Ask about native integrations, API options, and the provider's experience with your current ERP or accounting systems.
• Security credentials: Check for industry-standard certifications, data encryption practices, access controls, and incident response plans.
• Scalability potential: Ensure the solution can grow with you—handling more transactions, additional entities, or international expansion when needed.
• Industry-specific functionality: Look for features or compliance requirements unique to your sector, such as healthcare, government, or financial services.

Use this evaluation checklist during your provider search:

1. Customer support: What channels are available? Are there guaranteed response times? Can you get premium support if needed?
2. Training resources: What onboarding and ongoing training do they provide? Can you access self-serve resources? How often is documentation updated?
3. Reference customers: Can they connect you with similar organizations? What challenges did those customers face?
4. Contract flexibility: What's the minimum commitment? How are price changes handled? What exit options exist if the solution doesn't meet your needs?
5. Product roadmap: How often are features updated? How do they incorporate customer feedback into development?

As you decide, prioritize what AP goals matter most for your business. If you have complex approval workflows, look for configurable routing features. If you process many invoices, focus on OCR accuracy and exception handling. The right provider will support your AP function now and as it grows.
