Automating Invoice Processing with Filestack’s OCR API

An invoice is a document consisting of the costs of products or services purchased or sold. It shows the amount a buyer needs to pay a seller. Companies often manage invoices, depending on whether they bought or sold products/services. A crucial step in invoice approval is extracting relevant data from invoices and entering it into your system. However, extracting data manually from several invoices is resource-intensive and prone to errors. Hence, many businesses use an invoice OCR API to automate invoice processing. An invoice OCR tool is super helpful for companies that deal with lots of invoices daily.

This article will discuss the different aspects of automated invoice processing. We’ll also show you how to process invoices efficiently with Filestack OCR API. 

What does automated invoice processing mean?

Automating invoice processing means:

• Extracting data from invoices
• Validating the data
• Entering it into the business system using a software solution.

It’s crucial to use an automation tool that integrates with your processes easily. This is because it helps streamlines your accounts payable processes.

Benefits of automating invoice processing

Automating invoice processing allow companies to extract accurate data from invoices quickly. Hence, it helps save time and costs. For example, companies don’t have to hire several individuals for manual data extraction.

Moreover, automated invoice processing can efficiently handle various types of invoices with different formats and information. And it provides highly accurate results, reducing the risks associated with financial losses. Automating invoice processing also makes detecting and preventing fraud and duplicated entries easier.

In contrast, manual invoice processing is time-consuming. Moreover, manual data entry is prone to human errors. For example, the accounting department first extracts data from invoices. Next, they verify data, check for errors and enter data into the accounting system. However, some errors can be overlooked since it’s a manual process.

Moreover, invoicing doesn’t stop here. The accounting department then confirms the information with various departments. Finally, they release payments to each vendor. Businesses also extract data from invoices for marketing purposes.

What technologies and tools are used for automated invoice processing?

Optical Character Recognition (OCR) technology or invoice OCR API

OCR is a valuable technology that automates data extraction from scanned documents and image files. It uses advanced machine learning for accurate text detection. This, in turn, enables users to digitize hard copies of their documents. These include invoices, passports, driver’s licenses, IDs, and more. OCR also makes it possible to search for specific information within documents.

Many businesses nowadays use a reliable invoice OCR API  for invoice data extraction. These APIs can efficiently handle various invoice formats, layouts, and lighting conditions. Moreover, an OCR API can extract accurate data from invoices. It can also convert them into an editable and searchable format. Additionally, advanced invoice OCR technology can extract data from structured and unstructured invoices. Some advanced tools also offer data validation.

Data validation tools

Data validation tools verify if the information extracted from invoices is correct. They compare the invoice data against relevant receipts, contract documents, and purchase orders. For instance, these tools can validate supplier information, invoice number, and total amount. They also report any missing data or discrepancies.

Integration with Accounting or ERP systems

Integrating automated invoice processing solutions with your ERP system automates the entire process. This also includes invoice approval and payment processing.

What are the key steps for automating invoice processing?

Invoice capture and digitization

If you want to extract data from printed or hard copies of invoices, you first need to digitize them. To do that, you need to scan the invoices and then feed them to the invoice OCR API. If you have digital invoices, you can directly proceed to perform OCR.

Data extraction and validation

Next, the OCR solution will extract data from invoices. Some tools also validate it to check the quality and accuracy of extracted data.

Invoice matching and data verification

The next step involves matching extracted data with relevant documents. These documents include purchase orders, contracts, receipts, and more. This helps ensure the extracted data is correct and reliable. Moreover, it also helps prevent fraud.

Exception handling and resolution

Exception handling involves managing situations where the extracted invoice data doesn’t match the information provided in relevant documents. For example, the total amount or ordered quantity could be stated incorrectly.

Approval workflow and payment processing

Once invoice expectations are resolved, the system approves the invoices and processes payments.
