At the digital transformation stage, invoice processing with many repetitive and rule-based tasks becomes the most affected field. Innovative companies face new opportunities when they are ready to take advantage of this technological shift. Progressive solutions like artificial intelligence (AI), robotic process automation (RPA), machine learning (ML), and cloud capturing may noticeably improve business process automation levels and reach the full savings potential.

What invoice scanning software is?

Invoice scan software represents an accounting solution that can scan invoices (paper and electronic), capture all relevant data, recognize it, and present this data in a machine-readable format of automated systems. An invoice scanner provides a seamless and fast transfer of invoice data into automated workflows.


Modern invoice scan software uses some or all of the following technologies:

  • Optical character recognition (OCR) translates scanned images of text (printed or typewritten) and transforms these scans into machine-encoded text.
  • Handprint recognition or intelligent character recognition (ICR) processes invoices filled manually. This software studies and identifies handwritten fonts and styles. Also, it learns how to improve accuracy and recognition.
  • Advanced rules-based templates put common data elements on the right pages with different layouts and formatting.
  • Artificial intelligence (AI) takes user feedback to train recognition templates automatically.
  • Natural language processing (NLP) interprets paragraphs of text and extracts needed data from them.
  • Robotic process automation (RPA) provides back-office integration into the hands of experienced users instead of programmers.
  • Preconfigured form templates and business rules for invoice processing applications.

Invoice scanning software most commonly uses optical character recognition (OCR) technology. It provides electronic or mechanical conversion of typed or printed text images into machine-encoded text. The file can be a scanned document, a document photo, a scene photo (text on signs or billboards in a landscape photo), or subtitle text shown on an image (television broadcast).

Sometimes invoice scan software integrates with intelligent character recognition (ICR) to increase the efficiency. As an advanced type of OCR, highly technological ICR can effectively read and analyse handwritten characters. This system allows companies to learn handwriting fonts and styles by a computer during processing. As a result, it improves the accuracy and recognition levels of the invoice scanning process. Invoice scanner software is created with similar solutions as other data extractors. The difference is in a specific configuration to recognise invoices because they are the most usual documents organisations need to automate.

Invoice scan software offers the capability of automation in invoice scanning, identifying its relevant data parts (a date, a vendor, an amount, an invoice number, and line item data) and importing electronic files. This technology also allows companies to store, manage and access digital data systematically and securely.

How invoice scan software works?

The process of paper invoice scanning and converting to live data in an accounting system consists of some typical stages.

The process of scanning and converting a paper invoice to live data.

Step 1 – Input At this stage, the software scans paper invoices, non-scanned PDF files, or other types of files. Then it converts these files to high-resolution JPG images. The function of automatic separation splits multi-invoice PDF files and handles attachments.

Step 2 – Invoice correction (preprocessing) The image preprocessing stage is needed to ease the task of the OCR software when it recognises a difference between a text and a background. The invoice correction stage goals are binarization, skew correction, noise removal, and skeletonisation.

Step 3 – Text detection After the preprocessing stage, the software leads to detecting data fields. At this stage, the system detects invoice aspects like tables and graphs.

Step 4 – Text recognition At this step, the software recognizes data and each data field like a product name, product quantity, an invoice date, an invoice number, etc.

Step 5 – Data validation OCR technology does not involve human interactions. Due to this, data validation appears to be a significant part of the whole process. At this time, the system provides the accuracy and quality of the recognized data by performing different checks. This stage of data verification helps approve the logical consistency of the data. The information can be extracted and put to use without any unexpected issues. This stage helps reduce possible OCR errors. AI can use corrections that occurred in validation to train and improve further software work.

Step 6 – Data extraction At this stage, the OCR software helps extract invoice data from different parts like tables, headers, footers, and other regions of the scanned document. Then the system uses the same data to fill relevant fields in electronic invoices and to feed this data into the requested accounting system. You can send exported final data to enterprise resource planning (ERP) software via API, database, or robotic process automation.

Invoice Scanning vs. Invoice Data Capture

Invoice scanning and invoice data capture are two essential processes in modern accounting and financial management. 

Invoice scanning primarily involves converting physical or digital invoices into digital images or PDFs using OCR technology. This process ensures that invoices are digitized and stored electronically for easier access and management. 

Invoice data capture goes a step further by automatically extracting key data fields from scanned invoices, such as invoice number, date, amount, and vendor details. This automated extraction reduces manual data entry efforts, improves accuracy, and accelerates the invoice processing cycle. 

The table below highlights the differences between invoice scanning and invoice data capture:

FeatureInvoice ScanningInvoice Data Capture
Key functionalityConverts physical/digital invoices to PDFs or digital imagesAutomates data extraction (date, invoice number, amount, tec.) from scanned invoices
Technology deployedOCRAI and ML, advanced OCR

CustomizationLimited, with focus on document captureCustomization of data fields, rules, and workflows
IntegrationIntegration with document management systemsSeamless integration with accounting software and ERP
Cost EfficiencyReduces costs related to physical document storageReduces costs through automation of time-consuming  (data entry) tasks

Together, these processes optimize accounts payable workflows and enhance overall efficiency in managing financial transactions.

What sectors integrate this technology?

All organisations that manage a large number of contractor paper invoices can receive noticeable benefits from invoice scanning software. As much invoice data you are hand-keying into your accounting software, as many working resources you can optimise by using an invoice scanner.

Invoice scan software becomes valuable when a company has over 100-300 invoices in a month. If a company manages smaller volumes, the potential return of investments (ROI) is not worth the expenses for an automation solution. Due to this, invoice scanning software can be useful starting for small and medium businesses that manage requested invoice numbers. The software helps digitalise and store scanned invoices.

Invoice scanner software is used in different industry sectors: government and public, financial services, business analytics, legal services, healthcare, and manufacturing.

Accounting firms and companies performing outsourced invoice processing or scan to invoice, expect to receive the most ROI from automation. Also, invoice scan software brings benefits on-shorting the data entry, giving extra security and care about your clients’ data.

Invoice scanning software advantages

Invoice scanning is an effective instrument for different businesses and brings many benefits from usage.

  • Time-savings. The invoice scanning process takes less time than manually printing, filling, and storing all paper invoices.
  • High accuracy. Invoice scanner software allows companies to complete their finance and accounting tasks accurately. It does not involve any possible errors in calculations, for example, how much money a company owes or is owed by customers or suppliers.
  • Reduced manual errors. An invoice scanner decreases errors in manually entering data into accounting systems. When an employee manually inputs data into system spreadsheets or databases, he can make errors like typos or others. Invoice scan software helps enter every piece of invoice data correctly each time during scanning. There is no possibility of errors because all information is transcribed automatically by an invoice scanner.
  • Increased effectiveness. Manual processing takes much time and energy of employees that are needed in other tasks like negotiations with clients. Invoice scan software helps reduce manual paperwork by 90%.
