How to Extract Data from Invoices and Receipts Automatically
FlipFiles Pro · June 2026 · 8 min read
Manual data entry from invoices and receipts is one of the biggest time sinks in finance and accounting work. An accounts payable team processing 500 invoices per month spends approximately 40 hours — a full working week — on data entry alone. AI-powered OCR (Optical Character Recognition) combined with intelligent field extraction automates this entirely.
The Difference Between OCR and Structured Data Extraction
Standard OCR converts an image of text into editable text — it gives you a wall of words. Structured data extraction goes further: it identifies what each piece of text means and places it in the correct field. The difference between "the text says 42,500.00" and "the Total Amount field contains $42,500.00" is what makes automation actually useful.
FlipFiles Pro combines Tesseract 5 OCR with a pattern-matching extraction layer that identifies common invoice fields regardless of how the invoice was formatted:
- Invoice number (detected from labels like "Invoice #", "Inv No", "Bill Number")
- Invoice date and due date (detected from multiple date format patterns)
- Vendor/supplier name (typically the largest text on the page)
- Billed-to name and address
- Subtotal, tax/VAT amount, and total
- Currency
- Payment terms
- Individual line items (description and amount)
Output Formats
FlipFiles Pro returns extracted invoice data as both an Excel file (with separate sheets for summary fields and line items) and a CSV file (for import into accounting software). The raw OCR text is also included in a third sheet for manual verification of any fields the system could not automatically identify.
Accuracy Expectations
Extraction accuracy depends on invoice quality and layout consistency:
| Invoice Type | Field Extraction Accuracy |
|---|---|
| Digital PDF invoice (not scanned) | 90-98% |
| High-quality scan (300 DPI+, flat) | 85-95% |
| Photo of invoice (good lighting) | 75-90% |
| Photo with distortion/shadow | 60-80% |
Receipt Scanning for Expense Reporting
The Receipt Scanner tool uses the same OCR pipeline optimised for retail receipts rather than formal invoices. It extracts store name, date, individual items and prices, subtotal, tax, total, and payment method — producing a structured expense entry ready for your expense reporting system.
For teams where employees submit paper receipts for reimbursement, photographing receipts and processing them through FlipFiles Pro before submitting eliminates the need to manually type each receipt's data into an expense form.
Business Card Scanner
The same OCR infrastructure powers the Business Card Scanner, which extracts contact information from business card photos and produces a vCard (.vcf) file. Tap the downloaded .vcf file on any phone and the contact is added to your address book instantly — compatible with iPhone, Android, Outlook, and Gmail.
