What is OCR for Invoice?

OCR (Optical Character Recognition) for invoice is a technology that converts scanned or photographed invoices into editable and searchable digital text. It streamlines the data entry process by automatically extracting information such as dates, amounts, and vendor details from invoices.

Example: Using Adobe Acrobat's OCR technology, a company can scan paper invoices from vendors like Office Depot and extract key details such as invoice number 12345 and total amount $567.89 for seamless digital record-keeping.

10 Step Optical Character Recognition for Invoices

Use our 10 step OCR invoicing process to efficiently manage your invoices.

1. Scanning the Invoice

Optical Character Recognition (OCR) begins with scanning the physical or digital invoice to capture its content. This step converts the invoice into a digital image. 

Example: A company receives an invoice from "DAN Supplies" for 100 widgets. They use a scanner to digitize the invoice, capturing all the details as an image file.

2. Preprocessing the Image

The OCR software preprocesses the scanned image to enhance its quality and readability. This may involve noise reduction, binarization, and deskewing to ensure accurate text extraction.

Example: The OCR software detects some smudges on the scanned invoice and applies noise reduction to remove them. It also straightens the image to correct any tilts.

3. Detecting Text Regions within the Image

The OCR system identifies and separates the text regions within the image. This step involves locating blocks of text, such as headers, line items, and totals.

Example: The software detects the header "Invoice" at the top, followed by blocks of text for items like "100 widgets" and "Total: $500."

4. Recognizing Individual Characters

The OCR software recognizes individual characters within the detected text regions. It uses pattern recognition and machine learning algorithms to convert images of text into machine-readable characters.

Example: The system recognizes the characters "A", "B", and "C" in "ABC Supplies" and converts them into digital text.

5. Post Processing for Error Correction

After recognizing the characters, the software performs post processing to correct any errors. This includes spell-checking, format corrections, and validating the recognized text against known patterns.

Example: The software corrects a misrecognized character in "Total: $500," ensuring it reads correctly and makes sense in the context of an invoice.

6. Extracting Relevant Data Fields

The OCR system extracts relevant data fields from the recognized text. This step involves identifying and categorizing information like vendor names, invoice numbers, dates, and amounts.

Example: The software extracts "ABC Supplies" as the vendor name, "INV-12345" as the invoice number, "06/30/2024" as the date, and "$500" as the total amount.

7. Validating Extracted Data for Accuracy

The extracted data undergoes validation checks to ensure accuracy and completeness. This involves cross-referencing with existing records and checking for inconsistencies or missing information.

Example: The system compares the extracted total amount of "$500" with the company's purchase order records to confirm the invoice details are correct.

8. Integrating Data with Accounting Systems

The validated data is then integrated into the company's accounting software. This step automates the entry of invoice details into financial records, reducing manual data entry.

Example: The OCR software automatically inputs the invoice details into the company's accounting system, updating the accounts payable with "ABC Supplies" and the $500 amount.

9. Archiving and Storing Invoice Data

The original scanned image and the extracted data are archived and stored securely. This ensures compliance with record-keeping requirements and provides easy access for future reference.

Example: The company saves the digitized invoice and the extracted data in their secure cloud storage, ensuring it can be retrieved if needed.

10. Review and Approval of Processed Data

Finally, the processed and integrated data is reviewed and approved by the appropriate personnel. This step involves verifying the accuracy of the OCR results and authorizing payment.

Example: The accounts payable manager reviews the invoice details in the accounting system, confirms their accuracy, and approves the payment to "ABC Supplies" for $500.

Example

MedEquip Supplies is a prominent supplier of medical equipment that aims to improve the handling of vendor invoices from receipt to archiving. Here’s how they implemented our simple 10 step process.

1. Receiving and Capturing MedEquip Invoices

Invoices for products like "X-Ray Machines" are received via email and uploaded into the OCR system for processing.

2. Enhancing Invoice Image Quality

The OCR system preprocesses images of invoices, such as those for "MRI Scanners," by deskewing, reducing noise, and adjusting brightness and contrast to enhance clarity.

3. Extracting Invoice Details

Using OCR technology, the system extracts key data fields from invoices, like invoice number 89345 and items including 15 units of "Surgical Masks" from HealthTech Inc.

4. Validating Extracted Invoice Data

Extracted data, such as invoice number 89345, is validated against predefined rules and existing records to ensure accuracy, flagging any discrepancies for review.

5. Correcting Invoice Data Discrepancies

Discrepancies, such as a quantity error in the "Ultrasound Gel" order, are corrected from 200 to 220 units based on the vendor's purchase order.

6. Integrating Invoice Data into ERP Systems

Validated data, like that for 50 units of "Stethoscopes," is integrated into the SAP ERP system, updating financial and inventory records.

7. Archiving Processed Invoices

Processed invoices, such as those for 30 units of "Patient Monitors," are digitally archived with metadata tags for easy retrieval.

8. Generating Invoice Reports

The system generates detailed reports, including all invoices processed in the quarter for HealthTech Inc., aiding in financial analysis and vendor performance monitoring.

9. Handling Exceptions in Invoice Processing

Invoices with issues, like those for 100 units of "ECG Machines," are flagged for manual review by the accounts payable team.

10. Improving OCR System Accuracy

Continuous learning from manual corrections, such as repeated adjustments to product codes like MED456, enhances the OCR system's future accuracy and efficiency.

Benefits of Using an OCR Solution for Invoice

Here are some of the benefits of using OCR solutions for invoices:

1. Improved Efficiency through Automated Data Extraction

OCR technology automates the data extraction process, significantly reducing the time spent on manual data entry. This leads to faster invoice processing and allows employees to focus on more strategic tasks.

2. Enhanced Accuracy by Minimizing Human Error
