By now, most finance teams understand the power of automation. However, many have yet to realize the extent to which artificial intelligence and machine learning can benefit processes.

According to reports, AP automation and AI lower processing costs by 81%, speed up processing times by 73%, and slash human errors by up to 40%

These financial tools are designed to build value through continuous improvement and focused process optimization, eliminating both fraud and human errors from critical business workflows.

In this article, we’ll take a closer look at the rise of AI and just how artificial intelligence is transforming the end-to-end AP process, including how it’s used, key benefits, and the best software available for automating finance today.

AI is Transforming Accounts Payable

Automation is finance’s greatest asset, and artificial intelligence plays an important role in the digital transformation of accounts payable processes. It introduces automation, machine learning, and complex algorithms to help a business improve accuracy, efficiency, and informed decision-making. 

Here are some of the main ways in which AI is impacting accounts payable right now:

Cost Savings

Implementing artificial intelligence in accounts payable processes leads to a multitude of savings across the board. The AP department can now take advantage of more early payment discounts, as AI will identify key areas for evaluating cash flow and discount terms.

The rise of robotic process automation (RPA) also works to mechanize labor-intensive systems like document management, filing, data entry, etc. These tools reduce the need for physical storage, manual processes, and human intervention.

Full Automation

AI invoice processing involves advanced technology like Optical Character Recognition (OCR). This is a smart scanner that will automatically extract all relevant data from an invoice, which can include (but is not limited to):

  • Invoice number
  • Vendor details
  • Invoice data
  • Line item descriptions

Invoice automation reduces the need for manual data entry, minimizing mistakes, and speeding up processing times.

Automated invoice processing also includes AI-powered workflows for approvals. Invoice AI can route invoices (and other documents) instantly to the appropriate approval channels, based on predefined rules and policies. 

Not only does this streamline the entire approval process, but it also reduces bottlenecks and ensures compliance with company policies.

Fraud and Discrepancies

The use cases for AP automation solutions involve fraud detection, prevention, and data validation. AI can validate and reconcile invoice data quickly and easily, against purchase orders and contracts. This helps to identify discrepancies early on in the process, preventing under/overpayments, late payments, and other costly mistakes.

Financial automation software also helps a business detect anomalies in invoice patterns and behaviors. The system will go on to flag any potentially fraudulent activities, and send notifications accordingly. 

This helps businesses prevent fake invoices from being processed through fast, automated systems.

Reporting and Analytics

What would the AP function be without advanced reporting and analytics? AI enhances the financial reporting process for a company and helps teams identify inefficiencies and areas for improvement.

Artificial intelligence will also analyze historical invoice data to predict things like:

  • Potential cash flow issues
  • Vendor behaviors
  • Payment trends

This enables a business to optimize payment strategies and make more informed decisions.

Vendor Management and Compliance

AI can assess vendor performance by analyzing key data points, like the quality of goods/services, payment history, and on-time delivery stats. This analysis can then be used to better inform vendor selection and the negotiation process.

Regarding compliance, AI streamlines the entire process and eliminates the headache of noncompliance. The technology can ensure tax compliance with laws and internal financial policies by automatically checking invoices for accuracy and adherence to regulations.

Smart Integrations

Advancements in finance AI have enabled companies to handle larger volumes of invoices without the need to significantly increase staffing levels. This is a particularly valuable tool for companies looking to scale or grow quickly.

AI-powered dashboards also integrate seamlessly with key enterprise resource planning (ERP) systems, creating a unified ecosystem for financial management.

How Can AI Be Used in Accounts Payable?

Recent studies reveal that almost 70% of AP teams have not automated the most pressing issues in their AP business processes. This includes manual tasks, where it’s acknowledged that someone still needs to look over the invoice and confirm it is correct.

As such, automating these tasks may feel a little disempowering, since you’re essentially trusting a robot to have the same level of discretion as a trained human.

However, manually keying into ERP systems is an underwhelming task at best. Teams should focus on more value-based, innovative jobs.

Here’s how AI can be used in accounts payable:

Coding Invoices and GL Mapping

Some of the most challenging AP tasks to automate are coding and mapping. That’s because multiple GL codes can apply to the same expense, split by line items or individual product codes. This makes assigning these codes a manual job and must be done after consulting with business teams and/or the CFO.

Additionally, assigning codes can be subjective. This can lead to contractual expenses being incorrectly tagged. Artificial intelligence and machine learning are incredible tools for invoice processing, particularly when it comes to assigning the right category and GL code to invoices.

This technology facilitates General Ledger (GL) mapping by remembering a selected code once a user chooses it, then automating the process next time, for the same vendor. The system is technically “learning” your AP team’s preferences when processing invoices.

A business can automate invoice coding based on LLM processing. This means the artificial intelligence tells you which GL the invoice should be categorized in. It can then be customized to offer multiple suggestions.

Fraud and Anomaly Detection

Artificial intelligence is used as a catch-all for fraud detection and reducing errors. It helps to eliminate duplicate invoices and prevents most problems before they happen. 

The system will automatically identify anomalies in invoice data and payment patterns. It will then flag any potential errors or fraud for further investigation.

Advanced AI tools now carry out fully-automated data validation processes to ensure data hygiene and exercise smarter duplicate detection. It goes a bit further than simply verifying if two files are the same. It will also check if the contents of two files are suspiciously similar.

AI algorithms will also validate extracted invoice data against a variety of business documents, purchase orders, contracts, and historical data. This ensures the invoice data matches all quantities, pricing, and expected terms.

The real value of AI is realized when it can recognize trends and learn from patterns. Accounting automation can manage the small tasks, performed multiple times, for various invoices and receipts.

Some of these smaller tasks include:

  • Sending a specific vendor’s invoice to a certain approver, every time
  • Assigning an invoice to the right category/project/class in the ERP
  • Changing the GL mapping for one specific line item on an invoice
  • Detecting duplicates by comparing invoices to existing records

The first step is finding the tasks ideally suited for iterated re-learning. This means the activities your business performs on a daily basis, over and over again. Some examples where AP automation machine learning works best include GL code assignments and category/class/project classifications.

In-Depth Reporting and Predictive Analytics

Artificial intelligence can determine vendor performance by analyzing delivery times, payment history, and qualitative reports. AI-generated reports provide greater insights into the accounts payable process, helping companies identify top trends, potential areas for cost savings, and opportunities for improvement.

AI will also optimize cash flow by suggesting optimal payment schedules based on available cash flow. This ensures bills are always paid on time, while maintaining healthy cash reserves.

Automation technology also assists with predictive analytics, analyzing historical data to better identify cash flow trends, payment patterns, and potential gaps. This leads to better financial planning and more efficient growth strategies.
