Invoice Verification

Tool Introduction

"Invoice Verification" is an efficient and convenient online tool designed to help users quickly verify the authenticity of VAT invoices and query detailed information. Users can perform verification in two main ways: first, by uploading an invoice image, the tool will use OCR technology to automatically identify key information on the invoice; second, by manually entering key fields such as invoice code, invoice number, issue date, seller tax ID, total price and tax, and region code.

To improve the accuracy of image recognition, the tool also provides an image scaling function. After uploading an image, users can choose "Size Scaling" or "Ratio Scaling" to preprocess the image and optimize the recognition effect. Whether you are a finance professional, business owner, or individual, you can use this tool for preliminary invoice verification to effectively prevent the risk of fake invoices.

Significance of Invoice Verification

In daily operations and financial management, invoices are important vouchers involved in various aspects such as tax compliance, cost accounting, and reimbursement. The authenticity and validity of invoices are crucial. By verifying invoices, you can effectively:

• Prevent the risk of fake invoices: Timely identify fake invoices, voided invoices, or abnormal invoices to avoid economic losses and tax penalties.
• Ensure tax compliance: Verify that invoice information is consistent with the tax system to ensure the accuracy of enterprise tax declarations.
• Improve financial efficiency: Automated recognition and rapid verification reduce manual reconciliation workload and improve financial processing efficiency.
• Assist audit decisions: Provide data support for internal and external audits, strengthening risk control.

How to Use

1. Upload Invoice Image: Click the "Upload Image" area and select a clear invoice image (supports PNG, JPG formats, single image size not exceeding 5MB). This is a required step for invoice verification.
2. Adjust Image Scaling (Optional): If the uploaded image needs optimization, you can select "Size Scaling" or "Ratio Scaling" in "Scaling Type":
   • Select "Size Scaling": Enter the target width and height (unit: px), and choose whether to "Keep Aspect Ratio" as needed.
   • Select "Ratio Scaling": Enter a scaling ratio between 0 and 2 (e.g., 1.0 means no scaling, 0.5 means half size, 2.0 means double size).
   These settings help improve the accuracy of image OCR recognition, but if you are unsure, you can use the default settings or skip this step.
3. Enter Key Invoice Information (Optional): To assist recognition and improve verification accuracy, you can also manually enter information such as invoice code, invoice number, issue date, seller tax ID, total price and tax, and region code.
4. Click the "Verify" Button: After completing the image upload and information entry, click the blue "Verify" button, and the tool will start processing and verifying the invoice information.
5. View Verification Results: After verification is complete, the detailed invoice information will be displayed in a list at the bottom of the page, including invoice code, invoice number, issue date, seller/buyer information, total price and tax, invoice status, etc.

Frequently Asked Questions

• Q: What invoice image formats and sizes are supported?
  A: Currently, PNG and JPG image formats are supported for upload, with a single image size limit of 5MB. Please ensure the image is clear for accurate recognition.
• Q: Is it mandatory to upload an image for invoice verification?
  A: Yes, according to the configuration of this tool, uploading an invoice image is a required item. Manually entering key invoice information can serve as an aid to improve the accuracy of recognition and verification.
• Q: What is the role of the image scaling function in invoice verification?
  A: The image scaling function aims to optimize the resolution and size of the uploaded image to suit the best recognition effect of OCR (Optical Character Recognition). Appropriate scaling may help improve blurry or excessively large/small images, thereby increasing the accuracy of invoice information extraction.
• Q: If the manually entered information is inconsistent with the image recognition result, which one takes precedence?
  A: In the actual verification process, the tool will comprehensively analyze the image recognition result and the manually entered information. It is recommended to ensure that the manually entered information is highly consistent with the original invoice to maximize the accuracy of the verification result.

Precautions

• Please ensure that the uploaded invoice image is clear and complete, avoiding key information being obscured, reflected, blurred, or cropped, as this will severely affect recognition accuracy.
• Image files must be in PNG or JPG format, and the size of a single image must not exceed 5MB.
• All manually entered invoice information should be completely consistent with the content of the invoice image; any slight difference may lead to verification failure or inaccurate results.
• The invoice verification results provided by this tool are for reference only and have no legal effect. For final financial processing and tax declarations, please refer to the official verification results of the tax authorities or relevant regulations.
• Please do not upload invoice images containing personal sensitive information (such as ID card numbers, bank card numbers, etc.) or core corporate trade secrets to protect your data security.
