Best OCR For Invoice Processing (Updated List)


The game-changing OCR (Optical Character Recognition) technology dramatically changes how scanned documents can be used in the modern digital environment. We can efficiently edit and interact with PDF documents because of this technology, which enables computers to recognize and extract text from a number of sources, including scanned PDF documents. With the help of optical character recognition (OCR) software like Adobe Acrobat, the process of extracting text from scanned documents and converting them into editable PDFs or searchable image PDFs can be accomplished swiftly and effortlessly.

By leveraging powerful tools and APIs provided by OCR libraries such as Tesseract and IronOCR, with machine-learning techniques, developers gain access to advanced algorithms that enable them to harness the full potential of optical character recognition technology. Accurate text recognition is made possible by these libraries, making it easier to organize and obtain helpful information from both newly created documents and papers that have already been scanned. Making the most of scanned documents and page pictures with OCR provides seamless content analysis and aids in productivity optimization for enterprises and individuals. Whether used to digitize paper-based records, extract data from invoices, or just improve document accessibility, OCR is a crucial tool in modern technology.


Accounts payable staff can often handle and process invoices while keeping in mind the complex nature of invoices with the best-automated invoice processing software and invoice management software. For instance, accounts payable teams can scan paper invoices and convert them to an electronic format using AvidXChange. An employee can compare the amount and information on the scan with that on the receipt or purchase order once the invoices have been converted. Then, this data might be available through a single dashboard. AvidXChange integrates seamlessly with existing accounting software.

This kind of invoice scanning software makes use of OCR software, which can turn your invoices and other payables information into digital text. These digital copies provide you the freedom to do away with conventional filing or other storage techniques because each scanned document may be categorized and classified according to a wide range of criteria. In turn, this can result in a decrease in the quantity of paper a business needs to consume.

Additionally, each of the suppliers that your business uses can utilize a different system for generating invoices. Your accounts payable staff may need to manage numerous distinct payment methods for a variety of different suppliers because not all vendors want to utilize the same method to collect payments. The use of AvidXchange might simplify juggling these approaches. Check the Official site for more info here.

Contrary to the default Tesseract library, IronOCR extends Tesseract and offers a native C# OCR library with increased accuracy, performance, and stability. Text from PDFs and photos can be extracted using in .NET software and websites. It may output plain text or structured data and supports many foreign languages. It has the ability to read barcodes and text-filled pictures. The OCR library from Iron Software may be used in Dot NET console, web, MVC, and desktop applications. The licensing procedure for commercial deployments is directly assisted by the development team. The most recent versions of Visual Studio are compatible with IronOCR.

Advantage of IronOCR

  • IronOCR can read paper documents, barcodes, and QR codes from a variety of images or PDF files using the most recent Tesseract 5 engine. The integration of OCR into desktop, console, and web applications is made simpler by this package.
  • We can execute OCR with the aid of IronOCR, turning scanned PDFs into searchable PDFs.
  • Worldwide, IronOCR supports 127 distinct languages in addition to word lists and bespoke languages.
  • More than 20 distinct kinds of barcodes and QR codes can be scanned with IronOCR.
  • Both barcode data and plain text output are available from IronOCR. By employing an alternate structured data object paradigm, developers can retrieve all content for direct insertion into a system. This applies to online applications' organized headings, paragraphs, lines, words, and characters.

Invoice Processing Using IronOCR

Receipt data may be extracted and accessed with the help of IronOCR, a potent OCR library. Without sacrificing data privacy, you may use IronOCR to snap a picture of a receipt and turn it into machine-readable text that can be readily analyzed and processed.

Here is a demonstration of how receipt OCR functions using IronOCR to extract text from a receipt.

var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.EnglishBest;
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5;

using (OcrInput ocrInput = new OcrInput("Demo.gif"))
    OcrResult ocrResult = Ocr.Read(ocrInput);
    var totalPrice = ocrResult.Text.Contains("Total Current Charges") ? ocrResult.Text.Split("Total Current Charges")[1].Split("\n")[0] : "";
    Console.WriteLine("Total Current Charges : " + totalPrice);
var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.EnglishBest;
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5;

using (OcrInput ocrInput = new OcrInput("Demo.gif"))
    OcrResult ocrResult = Ocr.Read(ocrInput);
    var totalPrice = ocrResult.Text.Contains("Total Current Charges") ? ocrResult.Text.Split("Total Current Charges")[1].Split("\n")[0] : "";
    Console.WriteLine("Total Current Charges : " + totalPrice);

We are creating functionality for Iron Tesseract in the aforementioned code snippet. To facilitate the addition of one or more image files, we are constructing an OcrInput object. We might need to give the image's path in the code when utilizing the OcrInput object's Add method. You can include as many invoice images as you like. We can use the "Read" feature of the IronOCR object that we previously established to access the photos by parsing the image documents and extracting the results into the OCR result. It's capable of taking text out of photos and turning it into a string. In the above code, we are extracting the total price from the invoice.

There are different OCR tools available in the market which helps us to process data from the invoice. OCR processing invoices allows to read the data from the given invoice image into text. The first three OCR tools help us to process invoice data and allow us to avoid manual data entry work, which helps us to automate invoice scanning and data validation. Some OCR tools required an active internet connection and the cost of the tool is also high. It is supported by a few environments.

On the other hand, Several .NET projects, including .NET Framework Standard 2, .NET Framework 4.5, and.NET Core 2, 3, and 5, are supported by IronOCR. It also functions with more recent technologies like Azure, Mono, and Xamarin. We can improve Tesseract's output and fix incorrectly scanned texts or images by using IronOCR technologies. The NuGet Package controls the intricate Tesseract dictionary system. To create an OCR tool, we use the IronOCR Library. So IronOCR is the best invoice OCR software for invoice automation and extracts data with few lines of code.
