How it works
Saudi purchase invoices in, a ZATCA-ready VAT spreadsheet out — in 3 steps.
What happens behind each step
1. Upload your invoices
Drag a folder of purchase invoices onto the page, or click to browse — PDF, JPG, and PNG are all supported, up to 200 MB per batch. Multi-invoice PDFs are automatically split into individual invoices before processing, so you don't need to separate them yourself first.
2. Enter your VAT registration number
Type in your 15-digit VAT number (Western or Arabic-Indic digits both work). Voltax uses it to tell your company apart from the supplier on every invoice, and to confirm a file is a purchase — not a sales invoice you issued yourself, which is automatically detected and excluded.
3. Voltax reads and validates each invoice
Each invoice is scanned for its ZATCA QR code first — a valid code is trusted as proof it's a genuine tax invoice. AI extraction reads the date, supplier, invoice number, VAT number, and amounts; the 15% VAT calculation is checked against what's printed, and duplicates (matching invoice number + VAT number) are skipped automatically. Anything that doesn't add up is flagged in your results so you can review it before filing.
4. Export your spreadsheet
Download an Excel or CSV file with every extracted invoice already laid out as an input-VAT (purchase) register — date, supplier, invoice number, VAT number, taxable amount, VAT, and total. Rows that need a second look are color-coded so nothing slips through unreviewed.
