Everything you need to know about AI invoice processing
Haisem outputs standard CSV files compatible with all major UK accounting software including Xero, QuickBooks, Sage, FreeAgent, Kashflow or any other software that supports CSV imports. The CSV report includes nominal codes, VAT codes, and categories formatted for easy import. No special integrations needed.
Yes. Haisem extracts VAT amounts, codes (Standard, Zero, Exempt, etc.), and generates VAT summaries. However, Haisem is designed for invoice data extraction, not VAT return filing. You'll still need to review the data and file through MTD-compliant software like Xero, QuickBooks, or Sage.
Upload all your month's supplier invoices at once (up to 50 per batch). Get a single CSV report with categories, nominal codes, and VAT codes ready to import into your accounting software. Perfect for month-end processing.
Haisem automatically assigns UK standard nominal codes from 23 common expense categories including Cost of Sale (5000), Professional Fees (7300), Insurance (7205), Rent (7100), and Utilities (7200), etc. The codes are designed to work with Xero, QuickBooks, and Sage. You can remap codes in the report itself or your accounting software if your chart of accounts differs.
Yes. Haisem automatically categorizes invoices into UK accounting categories like Insurance, Professional Fees, Utilities, Cost of Sale, and more. Categories are matched based on supplier type and invoice content. The CSV report includes both the category name and corresponding nominal code.
Haisem uses AI-powered OCR optimized for UK invoices. Accuracy is typically high on standard invoices with clear text. We automatically flag invoices that need review (missing dates, unusual amounts, etc.) so you can verify before importing. Always review the CSV report before posting to your accounts.
Always review the CSV report before importing to your accounting software. Haisem achieves high accuracy on clear, standard UK invoices, but you should verify supplier names, amounts, and VAT codes. The CSV format makes it easy to spot-check and correct before import.
Yes. Process one client at a time: enter the client name, upload their invoices (up to 50 PDFs), and get a CSV report for that client. Then repeat for your next client. Each report is organized by client, making it easy for bookkeepers and accountants to manage multiple clients separately.
Haisem processes UK supplier invoices, credit notes, and receipts. We focus on purchase invoices (expenses) from suppliers to your business. The system automatically detects document types and handles multi-page PDFs.
Haisem works best with clear PDF invoices or high-quality scans. Very poor quality images, handwritten invoices, or heavily distorted scans may have reduced accuracy. We recommend using 'Scan to PDF' from your phone or scanner for best results.
Your uploaded PDFs are processed immediately and deleted from our servers within 24 hours. Only the extracted CSV data (supplier name, amount, date, etc.) is retained for 90 days to allow you to download reports. We never store your documents long-term. All data is encrypted in transit and at rest.
