Challenges in the Account Payable Process 

When it’s all about billing processes, the most common challenges are related to the nature of the processes and the time. 

Simple categorization may seem like this: 

• Repetitive Manual Tasks and High Scope of Error

Downloading invoice attachments from emails, reading them, and then filling up the data into the enterprise resource planning system. Besides taking your employees' precious time in this repetitive time, the nature of the activities brings additional fatigue and stress for them. 

• Service Level Agreement Breach 

Several approvals related to invoice processing often lead to the complete slowing of the billing cycle and penalties.

• Slow Cycle Time

Invoice processing consumes more time because of the manual approvals and activities that are interdependent on several organizational roles and responsibilities. Besides, it can bring dissatisfaction with service quality. 

• Invoice to Payment Mismatches 

Invoice mismatching is a significant activity in accounts payable. But, conventional approaches to these vital tasks may cost time, effort, and human resources, accompanied by inconsistencies and errors. 

Here, we'll explore the capabilities of Robotics Process Automation for optimizing invoicing workflow.  

Manual vs Automated Invoice Processing: A Clear Contrast

Before adopting invoice automation, many businesses still struggle with high costs and long cycle times. According to 2025 research, 68% of companies still enter invoice data manually, and the average cost to process one invoice manually is about $15, often taking 14.6 days from receipt to payment.

By contrast, modern invoice workflow automation, especially when using RPA, dramatically reduces both time and cost. Organizations that implement end-to-end invoice automation typically cut invoice approval cycles to just 3–4 days. Moreover, they reduce processing costs by up to 70–80%, enabling better cash flow management and lower error rates.

This before vs after view gives businesses a measurable framework to evaluate whether automating invoice processing will deliver real ROI rather than just incremental improvement.

What is Invoice Processing With RPA? 

Invoice processing +  RPA = “Invoice Processing Automation”. 

Invoice processing automation is used by businesses to optimize AP (Account Payable) processes. It sheaths everything from scanning and extracting invoice data, to seamlessly inputting data into an ERP or accounts payable system. 

The outcome is the potential to complete payments within minutes. 

Furthermore, automated invoice processing helps address crucial challenges in manual AP processing. You can see from the below statistics, the complexity of managing account payables increased exceptionally during the COVID-19 times.

Undoubtedly, businesses and organizations actively adopt numerous invoicing automation tools, especially RPA (Robotics Process Automation), during and after epidemic time. 

“RPA in Invoice Automating” is a trusted solution for rule-based process automation that uses the user interface and can run on any software like ERP systems or web applications. Besides, compared to other technologies like BPM (Business Process Management), RPA offers financial and operational advantages faster than going easy on the pocket. 

Businesses integrate RPA to bring automation to the following areas of finance operations: 

• Account Payable: It includes extracting invoice data, vendor validation, and vendor invoice processing. 
• Account Receivable: This includes customer data setup, management, monitoring customers’ credit status, and generating and distributing invoices. 
• Financial Reporting: This is about producing balance sheets, profit and loss reports, regulatory reports, and income statements. 
• Intercompany Reconciliation: Reconciliation means extracting and verifying data from files, exception handling and monitoring, and validating journal entries. 

There’s more RPA can do!

Robotics process automation transforms finance operations functions in the middle- and back-office operations. 

Checklist to consider when adopting RPA for invoice automation: 

• The requirement for high-level precision and consistency.
• Highly dependent on data manipulations, data entry, and generating reports.
• Need to collect information from several sources and systems.
• Repetitive and manual nature of numerous processes that can be easily automated. 
•  The need to adhere to strict regulatory requirements.

Notably, considering the automation purpose and complexity of the process, RPA can be used solely or can be easily amalgamated with technologies like AI (Artificial Intelligence), NLP (Natural Language Processing), Machine Learning, and IDP (Intelligent Document Processing).  

In simple terms, every combination offers unique benefits, but first and foremost, invoicing automation allows employees to dedicate time and effort to crucial tasks, bringing more value to the company.

The Full Invoice Automation Lifecycle (Invoice Workflow Automation)

To understand why invoice process automation is transformative, it helps to visualize invoice lifecycle automation from start to finish. In a fully automated workflow:

• Invoice Intake: Invoices arrive through emails, portals, or EDI feeds and are automatically captured.
• Data Extraction & Classification: Intelligent systems extract invoice fields such as vendor, PO number, and line totals.
• Validation & Matching: Invoice data is automatically matched against purchase orders and receipts.
• Exception Handling: Any discrepancies are flagged and routed for human review.
• Approval Routing: The system automatically routes the invoice for approval based on predefined rules.
• ERP Posting & Payment: Approved invoices are posted into ERP and scheduled for payment with complete audit trails.

This full-cycle automation reduces the average approval time from over 10 days to just 3 days, significantly accelerates the invoice-to-cash cycle performance, and increases data consistency and compliance visibility.

With this, let us quickly jump to the next question.

How does RPA automate the Invoicing Process? 

Let’s see! 

To automate invoice processing, an RPA will typically take the following steps:

Step 1: Identify Invoices 

The first step to automate invoice processing is to train the RPA bots to identify these invoices, whether that’s through a dedicated vendor portal, EDI (Electronic Data Interchange), emails or all of them.  

Step 2: Extract Relevant Data

After identifying an invoice, the RPA bots scan it and organize data to copy it precisely into other apps and systems like accounting software or ERP. Besides, data recognition often needs AI elements, like NLP or computer vision, for advanced cognitive capabilities that let bots identify and classify key data regardless of the invoice format.  

Step 3: Match Invoice with PO (Purchase Order) and Documents 

RPA bots easily compare line items between invoices and related account payable documents, like purchase orders (PO) or goods receipts. Furthermore, they verify the information on both ends and even notify vendors of any mismatch. 

Step 4: Handling Exceptions & Edge Cases in Invoice Automation

Even the best automation workflows face exceptions such as missing purchase orders, incorrect item details, or quantity/price mismatches. Modern invoice workflow automation tools leverage RPA bots, combined with machine learning or OCR-based systems, to identify anomalies, automatically notify responsible stakeholders, and escalate unresolved exceptions in accordance with SLA rules.

In fact, recent industry surveys show that around 14% of invoices require exception handling due to missing data or errors, which can disrupt cash flow if not managed quickly. By automating exception handling, businesses can dramatically reduce manual rework time and minimize late payment penalties, ensuring smoother end-to-end invoice processing.

Step 5: Payments to ERPs

Once the invoice is approved and paid, RPA bots seamlessly post the payments to your ERPs - ensuring precise data and a well-defined audit log and process.  

Surprisingly, the adoption of automation in invoicing grows significantly year to year. Presently, about 52% of companies automate their account payable processes. 

Considering the trend, you must be wondering what benefits automating invoice processing brings.

Here’s the answer!
