Automated invoice processing can also help a business reduce the error rate. Research shows that 39% of manually processed invoices have at least one error, while AI-powered automated invoice processing can have an error rate of less than 0.1%. In this guide, we are going to explore steps to automate invoice processing, including an estimated cost and some useful automation software.

What is Automated Invoice Processing?

Automated invoice processing, also known as invoice automation, refers to using technology or software to handle accounts payable activities. It helps businesses or invoice processing services automate repetitive tasks such as capturing, extracting, and validating invoice or receipt data and storing it in an ERP system.

Core technologies typically used in automated invoice processing include:

• OCR: It stands for Optical Character Recognition, a technology that can extract text from images and transform it into a format that a computer can understand and interpret. This technology is often used for AI-assisted data entry tasks that include extracting invoice or receipt data.
• Machine Learning: Machine learning is a field of AI that can recognize patterns and learn from data. It can be used to digitize and validate invoices from scanned PDFs or images.
• AI: Artificial intelligence or AI, has contextual understanding and it can be used to reduce the error rate for invoice processing and prevent fraudulent attempts in payment processing. AI can be used for checking duplicate data, inaccurate information and fake invoices.
• ERP and Digital Workflow: ERP stands for enterprise resource planning. It is software that businesses use to manage and integrate their core operational processes such as HR, finance, accounting and supply chain management.

Key Steps to Automate Invoice Processing

There are several steps that a business or invoice processing service usually takes to automate its workflow:

Step 1: Study the Existing Process

Automation can help a business improve its existing workflow for performing specific tasks. This is why you first need to identify the inefficiencies in your manual workflow. While studying your current system, you will notice many issues such as operational bottlenecks, repetitive tasks or frequent errors occurring in particular steps.

Identifying those issues will help you design an effective automation process that solves the major problems you experience in invoice processing. Then, you should take insights from your finance and accounting team to ensure that your design workflow aligns with their expectations.

Step 2: Establish Clear Objectives

Redesigning or upgrading your workflow may not give you any significant benefits if you don’t have any specific objectives. This is why you need to define some primary objectives, such as saving costs, reducing the error rate and avoiding delays in payment processing. It will help you measure the performance of the automated workflow after implementation. Without setting clear goals, you can easily miss some significant benefits of invoice automation. For example, you can set a goal to save at least 30% of your current invoice processing costs.

Step 3: Choose the Right Invoice Automation Software

To automate your invoice processing activities, you will need to select the software that suits your business needs. Here are some key facts you need to consider:

• What type of invoice format or receipt do you need to process, such as paper documents, email or PDFs?
• Do the software programs you want to use for automation have the ability to integrate with your existing accounting or ERP software?
• How will the software meet your invoice processing needs in the future?
• How can the software help you reduce the cost of invoice processing?
• What are some risks and challenges (for example, cost and complexity of training your employees, hardware updates and data security risks) of using that software?

Step 4: Create Digitized and Standardized Invoice Formats

The invoices you process must meet some specific requirements for legal and security purposes. It will be necessary to ensure that they are authentic and accurate. The invoices you need to process for your business can be in different formats. Some might be in paper format, while others might be in PDF or scanned format.

So you will need to transform them into electronic format or electronic invoices before processing them through your ERP software. After that, you need to verify the authenticity of your invoices and may need to approve them by using techniques such as electronic signatures, timestamps and digital certificates. This will ensure that the electronic invoices you have prepared are verified and ready for processing.

Step 5: Implement Workflow Automation

Prepare a system for workflow automation after standardizing incoming invoices for your ERP software. Design the routes for uploading, reviewing and approving the invoice. Set routing rules based on specific criteria such as expense type, amount or vendor. Create a system for raising exceptions when reviewing or approving specific invoices that require more precaution. The automation system must notify the right individuals before processing a payment so that they can take immediate steps to pause that payment if further review is necessary.

Step 6: Monitor and Adjust the Workflow

After implementing automation, you need to monitor your workflow and see how it is working. Analyze its performance against the established Key Performance Indicator (KPI) and ask for feedback from the finance team. The performance review and feedback will help you identify issues that you can improve in your workflow. Regular monitoring and review are also necessary because you need to adjust your workflow with changing legal requirements and security risks.

How Invoice Automation Workflow Works

The common stages of an invoice automation workflow include:

• Data Capture: The invoice data from paper or other documents is captured using OCR technology. This data may include vendor name, product name, amount, purchase order (PO) and other information.
• Data Validation: The captured data is matched against the PO, vendor information, master vendor files and other information that might be necessary for verification.
• Routing for Approval: The processed invoices get routed to the appropriate individual or department for approval.
• Payment Processing: The system can schedule payment after receiving an approved invoice.
• ERP Integration and Recording: The system stores the invoice and payment details and sends the approved invoice data to the ERP software.

What Should a Small Business Look for in Invoice Automation Software?

If you have a small business, then you need to choose invoice software that reduces your processing cost, gives accurate results and easily integrates with your existing system. This is because major hardware or software updates can be expensive, especially for a small business. This is why you need a solution that you can implement without making major changes to your ERP software.

Here is a table that can help you identify what you should prioritize and what to avoid while selecting invoice automation software.

Feature	Why it matters at your scale	What to skip
OCR accuracy on your invoice formats	Directly cuts the manual correction work your team would otherwise do	Custom OCR training for high-volume, non-standard formats

How to Implement Invoice Automation Without Disrupting Your Current Process

Automating your invoice processing system can be a bit concerning for some new small business owners. Some of them can be worried about disrupting their existing workflow, which may impact their ability to process payments on time if the automation fails.

Here are some tips that can help you minimize disruption to your existing workflow:

• Start using the automated workflow with your manual processing system. Don’t completely switch or abandon the manual process right after implementing automation. It will help you avoid sudden disruption of your invoice processing workflow.
• Use a low-risk approach for invoice processing by trying to process the invoices that are easy to verify, upload and digitize. You can decide to process invoices from a new vendor or high-amount invoices manually.
• Switch to a fully automated process when the exception rate is low. If you notice the automated process is working as expected, then you can prepare to drop your manual process.

How Much Does Invoice Automation Cost for Businesses?

Manual invoice processing requires you to pay for an AP clerk, data entry staff and other expenses. You can save these costs by automating your invoice processing workflow. Here is a table that includes a quick comparison of invoice automation costs with manual invoice processing:

Processing type	Estimated cost per invoice
Manual processing	$10 to $22
Semi-automated processing	$3–$5
Automated processing	$0.50–$1.00

Should You Use an Invoice Outsourcing Service Instead of Automation?

Invoice processing or AP outsourcing refers to delegating invoice processing tasks to a third party. It can reduce your invoice processing costs and give you several other benefits, such as increasing accuracy, managing seasonal workload and reducing operation workload of your AP team. Statistics show that a small business typically needs to pay $1.50-$5.00 per invoice or $200-$800/month for processing invoices with an outsourcing service

So if you have a small business and don’t want to invest in invoice automation, then you can decide to choose an invoice outsourcing service for your business. It will help you reduce the workload and cost of invoice processing and allow your staff to focus more on other activities.

Final Words

Businesses can use automated workflows to reduce costs and error rates in invoice processing. Processing invoices through automation at once can cause sudden disruption to workflow. So, in the beginning, they should also process manually. Once everything works perfectly, they can use a fully automated workflow for invoice processing. It is essential for you to study your existing system and identify its inefficiencies before starting to use an automated workflow for invoice processing.

Sometimes, using an automated invoice processing workflow may seem complex to you, as you need to invest in automation tools and change your existing workflow. If you have a small business, then you can also consider outsourcing your invoice processing tasks. It can also reduce invoice processing costs and help you process an increased volume of invoices in peak seasons.
