What is OCR in invoice processing?

Optical Character Recognition is a technology that modernizes invoice processing. In essence, OCR converts documents, such as scanned paper documents, PDF files, or images captured by a digital camera, into editable and searchable data. 

When applied to invoice processing, OCR scans and reads the text from invoices, converting it into machine-readable text that can be easily stored, searched, and manipulated within accounting systems. It automates the extraction of key data fields from invoices, such as invoice numbers, dates, vendor details, line items, and total amounts. By transforming these data points from static images or PDFs into dynamic text, OCR significantly enhances the efficiency of the accounts payable process.

Manual data entry tends to errors and inefficiencies, and it has become a thing of the past. Instead, OCR has several benefits: It facilitates the rapid and accurate extraction of data, ensuring the information is immediately available for further processing and analysis. This automation speeds up the invoice processing cycle and ensures higher accuracy and consistency in financial records.

How does OCR help in invoice processing?

OCR technology fundamentally transforms invoice processing by automating the data extraction process. This automation addresses several pain points inherent in traditional manual invoice processing, such as time consumption, high error rates, and inefficiency. Let's dive deeper into how OCR technology helps streamline invoice processing.

One of the primary benefits of OCR in invoice processing is the acceleration of the entire workflow. Traditionally, processing an invoice manually involves several steps: receiving the invoice, manually entering data into accounting systems, validating the data, and then approving and making the payment. Each of these steps is time-consuming and prone to human error.

But OCR automates the data entry part of this process. By quickly scanning and extracting data from invoices, OCR software reduces the time spent on manual entry. This enables faster document processing times, allowing businesses to handle more invoices with the same resources. The automation also ensures that data is captured accurately, which helps in reducing the time spent on corrections and rework.

Further, manual data entry is not only slow but also labor-intensive. It requires dedicated staff to handle the influx of invoices, enter data, and verify its accuracy. This manual process is prone to errors such as typos, missed entries, and incorrect data entry, which can lead to significant discrepancies in financial records.

OCR eliminates the need for manual data entry by automatically extracting information from invoices. This significantly reduces the workload on the accounts payable team, allowing them to focus on more strategic tasks such as managing vendor relationships and optimising cash flow. Moreover, by minimising manual intervention, OCR reduces the likelihood of errors, thereby improving the overall accuracy of invoice processing.

Through the above, OCR brings about significant improvements in both efficiency and accuracy. With OCR, invoices can be processed in a fraction of the time it would take manually. The extracted data is then directly integrated into the accounting software, ensuring that the information is accurate and up-to-date.

For example, a company receiving hundreds of invoices monthly can use OCR to extract data fields such as invoice numbers, dates, vendor names, and amounts due. This data is then validated against the purchase orders and receipts within the accounting system, ensuring consistency and accuracy. The process speeds up the workflow and ensures that the data is reliable, thus reducing the risk of financial discrepancies.

Consider a large retail company that processes thousands of invoices each month. By implementing OCR technology, the company can automate the extraction of key data from these invoices. The OCR software scans each invoice, extracts the relevant data, and uploads it to the company’s accounting system. This process, which once took several days of manual effort, can now be completed in a matter of hours, with minimal human intervention and higher accuracy.

Another example could be a manufacturing firm that receives invoices in various formats—some as PDFs, others as scanned images. Through OCR, the firm can standardize the data extraction process across all these formats, ensuring uniformity and consistency in its accounts payable records. This enhances efficiency and enables the firm to have a clear and accurate view of its financial obligations at any given time.
