How to Create Professional Invoices in Pakistan (With Free Template)

A professional invoice is more than a payment request—it’s a legal document, a reflection of your brand, and for GST-registered businesses in Pakistan, a compliance requirement. This guide covers everything you need to create invoices that get you paid faster while keeping FBR happy.

What is an Invoice?

An invoice (or bill/فاکچر) is a commercial document issued by a seller to a buyer detailing the products or services provided, quantities, prices, and payment terms. In Pakistan, invoices serve multiple purposes:

• Payment Request: Formally asks customers to pay
• Legal Record: Proof of transaction for disputes
• Tax Document: Required for GST compliance
• Accounting Record: Basis for accounts receivable
• Business Proof: Required for bank loans, tenders

Invoice vs Receipt vs Bill

Document	When Issued	Purpose
Invoice	Before/at time of sale	Request payment
Receipt	After payment received	Confirm payment
Bill	Same as invoice (informal term)	Request payment

Essential Elements of a Pakistani Invoice

Every invoice should include these elements:

1. Your Business Information

• Business/Company name
• Complete address
• Phone number and email
• NTN (National Tax Number)
• STRN (Sales Tax Registration Number) – if GST registered
• Logo (recommended for professionalism)

2. Customer Information

• Customer/Business name
• Address
• Contact details
• Customer NTN/STRN (for B2B tax invoices)

3. Invoice Details

• Invoice Number: Unique sequential number (e.g., INV-2025-001)
• Invoice Date: Date of issue
• Due Date: When payment is expected
• Reference/PO Number: Customer’s purchase order (if applicable)

4. Line Items

• Description of goods/services
• Quantity
• Unit price (before tax)
• Total per item
• HSN/PCT codes (for certain goods)

5. Tax Information

• Subtotal (before tax)

6. Payment Information

FBR Tax Invoice Requirements

For GST-registered businesses, FBR mandates specific invoice requirements:

• Seller’s name, address, and STRN
• Buyer’s name, address, and STRN (for registered buyers)
• Date of issue
• Description of goods/services
• Quantity and value
• Amount of sales tax charged (separately shown)
• Total value including tax
• Unique serial number

Important: Invoices not meeting these requirements may not be accepted for input tax credit claims by your customers.

How to Calculate GST on Invoices

Adding GST to Price

If your price is Rs. 10,000 (exclusive of tax):

• GST (18%) = Rs. 10,000 × 0.18 = Rs. 1,800
• Total Invoice = Rs. 11,800

Extracting GST from Inclusive Price

If total is Rs. 11,800 (inclusive of tax):

• Taxable Value = Rs. 11,800 ÷ 1.18 = Rs. 10,000
• GST = Rs. 11,800 – Rs. 10,000 = Rs. 1,800

Modern accounting software handles these calculations automatically.
