What is invoicing software?
Invoicing software, also called billing software, is a tool for creating, sending and tracking invoices for the goods or services you sell. Good invoicing software also records payments, calculates sales tax and updates your stock and accounts automatically. In Pakistan, it should also send sales-tax invoices to FBR digitally.
AIM Sales does all of this in one place: quotations, sales orders, invoices and customers, connected to AIM’s Inventory, Accounting, Payments and Returns modules.

How a sale moves
From quotation to payment in one flow
Most businesses still move one sale through a bill book, a WhatsApp chat and an Excel sheet. AIM keeps every step on one record, so nothing is typed twice.
Quotation
Send a professional quote with your prices, discounts and terms.
Sales order
Convert the accepted quote into an order in one click, without re-typing a line.
Invoice
Turn the order into an invoice. Sales tax is calculated, and FBR invoices get their IRN and QR code.
Stock
Posting the invoice deducts the sold items from stock in AIM Inventory.
Payment
Record full or part payments and see the customer’s outstanding balance at once.
Return
If goods come back, a sales return corrects stock, the balance and your books in one step.

Everything you need to bill customers
Quotations & estimates
Create and send quotes, then see which ones were accepted and convert them.

FBR Digital Invoicing
FBR digital invoicing, built into every sale
Under FBR’s S.R.O. 709 of 22 April 2025, electronic invoicing is mandatory for corporate and non-corporate sales-tax-registered persons. Each invoice is reported to FBR, which returns an invoice reference number (IRN), and the printed invoice carries a QR code the buyer can scan to verify it.
With AIM you don’t need a second tool. Connect your FBR IRIS account once, and AIM submits your sales invoices to FBR from the same screen you create them on, with the IRN and QR code printed on the invoice.
How FBR digital invoicing works in AIMFBR digital invoicing FAQs (opens fbr.gov.pk in a new tab)
Invoices go straight to FBR
Submit sales invoices to FBR IRIS from AIM — no re-typing them in another portal.
Your NTN, set once
Enter it in Company Settings and AIM uses it on printed invoices and in FBR filing.
Test in sandbox first
Run FBR’s scenario tests in the sandbox, then switch to production when you pass.
Taxes mapped to FBR
Map sales-tax rates, SROs and stock units to FBR, and choose the account output tax posts to.
You’ll need a static IP whitelisted with FBR/PRAL and a Bearer token from the IRIS portal. Your token is stored encrypted.
Invoicing that updates your stock and accounts automatically
A sale in AIM is never just an invoice. This is what separates invoicing inside an accounting and inventory system from a standalone invoice app.
Inventory
Sold items leave stock the moment the invoice posts, per warehouse.

Accounting
The sale and its tax post to the right accounts, with no double entry.

Payments
Receipts are matched to invoices, so customer balances stay correct.

Returns
Sales returns put stock back and reverse the balance and the books.

Invoicing and billing software FAQs
What is the best invoicing and billing software in Pakistan?
The best invoicing software for a Pakistani business sends sales-tax invoices to FBR digitally, prices in rupees, and connects billing to stock and accounts. AIM Sales does all three and lets you share invoices on WhatsApp.
Is AIM invoicing software free?
Yes. AIM has a free-forever plan for quotations, sales orders and invoices, with sharing by WhatsApp and email, and no credit card is needed. The Pro plan costs PKR 2,500 a month, or PKR 2,000 a month billed yearly, and adds FBR Digital Invoicing, accounting, payments, returns, multiple warehouses and team permissions.
Is FBR digital invoicing mandatory?
Yes, for sales-tax-registered businesses. Under S.R.O. 709 of 22 April 2025, electronic invoicing is mandatory for corporate and non-corporate registered persons. On the Pro plan, AIM connects to FBR’s IRIS system and submits your sales invoices, printing the FBR invoice reference number (IRN) and QR code on each one.
What do I need to connect AIM to FBR?
You need your FBR IRIS account, a Bearer token from the IRIS portal and a static IP whitelisted with FBR/PRAL. You enter your NTN once in Company Settings, test in FBR’s sandbox, then switch to production. AIM stores your token encrypted.

What is the difference between invoicing software and POS software?
Invoicing (billing) software creates and tracks invoices for any kind of sale, including credit sales to other businesses.

AIM Sales handles both invoiced sales and quick counter bills for walk-in customers; for high-volume checkout, a dedicated POS system is the better fit.
