InvoiceFlow connects your business directly to FBR's PRAL system — generating real-time IRN numbers, QR codes, and legally valid digital invoices in seconds.
FBR enforcement is live. Every day without compliance is a financial and legal liability.
Under Rule 150Q of the Sales Tax Rules 2006, amended by SRO 1852(I)/2025, every registered manufacturer, importer, wholesaler, distributor, and corporate supplier must issue digitally verified invoices through an FBR-integrated system.
Each invoice must carry an Invoice Reference Number (IRN) issued by PRAL — FBR's technology arm — and a QR code that buyers can scan to verify authenticity. Without these, your invoices are legally invalid and your buyers cannot claim input tax credit.
From invoice creation to FBR submission — in under 60 seconds.
Add buyer details, products, HSN codes, and tax rates. InvoiceFlow auto-calculates GST, FED, and all required fields exactly as FBR demands.
One click sends your invoice to PRAL's gateway via the official API. You receive an IRN (Invoice Reference Number) in seconds.
Your invoice is stamped with the FBR IRN and QR code. Print it, email it, or share a PDF — fully legally valid for your buyer's input tax claim.
Built ground-up for the Pakistani market. Every field, every rule, every requirement — handled.
