Complete step-by-step instructions for intelligent document scanning, auditing, and digital accounting management.

Module 1

Platform Overview & End-to-End Workflow

InvScanner automates optical text extraction from invoices, receipts, and tax documents using advanced computer vision and artificial intelligence.

Step-by-Step Instructions

11. Capture or Upload

Use the smart mobile camera to capture paper receipts with auto-edge detection, or upload multi-page PDF documents from desktop.

Both paper receipts and digital computer-generated PDFs are supported.

22. Intelligent AI Data Extraction

The Pulse AI Engine reads vendor details, customer information, tax IDs, invoice dates, individual line items, and VAT 7% automatically.

All currency calculations default to Thai Baht (฿ / THB).

33. Verification & Digital Stamping

Review extracted data on the interactive ledger, make adjustments if needed, and apply the Official Verification Stamp.

Stamped documents are stored securely in the Encrypted Document Vault.

44. Accounting & Audit Export

Export consolidated tax records to professional Excel reports or download stamped PDF archives at any time.

Best Practices & Helpful Tips

  • Ensure documents are legible before scanning.
  • Keep documents stored in the encrypted cloud ledger for audit compliance.
  • Check line item totals against physical receipts during the review step.
Module 2

Smart Mobile Camera & Auto-Boundary Detection

The mobile camera scanner features real-time edge detection and perspective warping to deliver flatbed-scanner quality right from your smartphone.

Step-by-Step Instructions

11. Open Smart Camera

From the Scan page, tap 'Open Smart Camera (Auto Edge)'. The app opens a fullscreen 1080p viewfinder.

On devices with flash support, toggle the flashlight (Torch) icon for better lighting.

22. Real-Time Green Boundary Tracking

Point your camera at the paper receipt. A glowing green quadrilateral frame will automatically latch onto the paper edges in real-time.

Place the invoice on a darker background (e.g. wood desk, dark countertop) for maximum edge contrast.

33. Auto-Shutter Capture

Hold the camera steady for ~1.2 seconds. The camera will automatically beep, vibrate with haptic feedback, and snap the photo.

You can also tap the large white shutter button at any time to capture manually.

44. 4-Corner Perspective Adjustment

After snapping, drag the 4 corner pins with your finger to fine-tune boundaries if the paper was slightly folded.

55. Crop & Scan PDF

Tap 'Crop & Scan PDF'. The system flattens perspective distortions, straightens the document, generates a crisp PDF, and begins AI extraction.

Best Practices & Helpful Tips

  • Always smooth out folded or creased receipts before scanning.
  • Avoid direct overhead glare on glossy thermal paper.
  • Hold the phone parallel to the paper for the clearest text resolution.
Module 3

Desktop PDF Document Upload

Easily process multi-page tax invoices and vendor billings generated from electronic billing software or flatbed scanners.

Step-by-Step Instructions

11. Select or Drag File

Drag any PDF invoice directly into the upload dropzone, or click 'Choose PDF File' to browse files on your computer.

Supported file formats: PDF, JPG, PNG, WEBP.

22. Automatic Processing

The document is securely transferred to the Encrypted Document Vault and parsed by the Pulse AI Engine.

33. Direct Handoff to Review

Once parsing completes, you are automatically redirected to the interactive Review and Verification screen.

Best Practices & Helpful Tips

  • For multi-page invoices, ensure all pages are bundled into a single PDF file.
  • Maximum recommended file size is 25 MB per document.
Module 4

Review, Line Items & Verification

Ensure 100% accounting accuracy by reviewing extracted fields side-by-side with the original document.

Step-by-Step Instructions

11. Verify Vendor & Customer Profiles

Inspect vendor name, branch, address, and 13-digit Thai Tax ID. Check customer billing information.

Branch code should be 5 digits (e.g. 00000 for Head Office).

22. Inspect Line Items & Tax Calculation

Review individual item descriptions, quantities, unit prices, and line totals. The system automatically verifies VAT 7% math.

You can add new rows or edit quantities and prices directly in the table.

33. Goods Receipt (GR) Records

Optionally record receiving warehouse location, inspector staff name, and physical inspection status.

Best Practices & Helpful Tips

  • Confirm that the pre-tax total plus 7% VAT matches the final grand total exactly.
  • Verify the invoice date format follows Thai business standards.
Module 5

Official Digital Verification Stamp & Vault

Permanently affix an official accounting verification stamp to the original document for audit compliance.

Step-by-Step Instructions

11. Apply Verification Stamp

Click 'Save, Stamp & Confirm' on the review screen. The system generates an official audit stamp with date, tracking code, and digital verification seal.

22. Encrypted Document Vault Storage

Both the original scan and the stamped audit PDF are preserved in the encrypted cloud repository.

33. Download Stamped Document

A green download button appears instantly, allowing you to save or print the verified document.

Best Practices & Helpful Tips

  • Stamped PDFs serve as immutable audit trail records for corporate compliance.
  • Always verify numbers prior to applying the permanent verification stamp.

Best Practices & Helpful Tips

  • Export Excel ledgers monthly for seamless filing with your accounting software.
