What every invoice must show
Whatever your trade, these fields are the minimum:
The word Invoice (or Tax Invoice where you charge Sales tax) and a unique sequential number.
Issue date and, for services, the date or period of supply.
Your business name, address and NTN; your registration number if you have one.
The client's name and address, and their NTN when they are a registered business.
One line per item or service: description, quantity, unit price and line total in PKR.
Subtotal, Sales tax rate and amount (or a statement that none was charged), and the total due.
Payment terms, due date and bank details.
In Pakistan specifically:
Sales tax invoice with the seller's STRN and NTN, the buyer's NTN and tax shown separately; tier-1 retailers must integrate with the FBR POS system.
Numbering and dates
Numbers must run in sequence with no gaps or repeats; Federal Board of Revenue (FBR) checks for both. Use a prefix per year or series if it helps (2026-001), but never reissue a number. The issue date fixes the tax period the sale falls into, so date the invoice when you send it, not when the work started.
Showing Sales tax
Only registered businesses charge Sales tax. If you are registered, show the rate and the amount as separate lines; if you are not, do not show a Sales tax line and say so on the document. Charging Sales tax without registration is an offence in most countries, and clients' accountants will spot it.
Electronic invoicing in Pakistan
Digital invoicing is now in force for everyone. SRO 1413(I)/2025 phased it in between 1 September and 1 December 2025 by turnover, and the final tranche brought all sales-tax-registered persons into scope. Note the FBR website still shows the superseded SRO 709 dates.
Many countries now require invoices to be issued through, or reported to, an official electronic system. Where Pakistan does, the PDF you make here is a working document for quotes, proformas and internal records, and the fiscal invoice comes from the official system. Where it does not, an emailed PDF is a valid invoice.
Getting paid
State the due date, not just the terms. Put the bank details on the invoice and ask for the invoice number as the payment reference. Send the PDF on the day the work finishes; late invoices are paid late. A proforma up front is the cleanest way to ask for a deposit.
Fixing a mistake
Never edit or delete an invoice you have sent. Issue a credit note that references the original number, states the reason and reverses the same Sales tax, then issue a new invoice if needed. The Pakistan credit note generator does this.
Questions people ask
Do I need to be registered to send an invoice?
You need a NTN; registration for Sales tax is only needed if you charge it. Many small businesses invoice without charging Sales tax.
Can I invoice in a foreign currency?
Usually yes for export clients, but Federal Board of Revenue (FBR) generally wants the Sales tax amount, and sometimes the total, shown in Pakistani Rupee at the official rate on the invoice date. Show both.
Is a PDF invoice legally valid in Pakistan?
Where Pakistan has no mandatory e-invoicing, yes: an emailed PDF with the required fields is a valid invoice. Where electronic issuance is required, the official system's document is the fiscal invoice and the PDF supports it.
What is the difference between an invoice and a receipt?
An invoice asks for payment and creates the debt; a receipt confirms payment received. Issue the invoice first, then a receipt or a marked-paid copy when the money arrives.
