If you ask most small retail business owners in Pakistan how much profit they actually made last month, you usually get a long pause and a guess. The reason is rarely that they don't care — it's that their sales report, their expense diary, and their stock register are three different things sitting in three different places.

A modern POS solves this by calculating profit, expenses and stock value in one place — and refreshing the number every time you ring a sale. Here's how it works.

The simple profit formula

At its core: Profit = Net Sales − Cost of Goods Sold − Operating Expenses.

Most retailers know the formula but can't actually compute it day-to-day because they don't know their real cost of goods sold. That's where a POS makes the difference.

How a POS calculates Cost of Goods Sold (COGS)

Every time you buy stock, your POS records the unit cost. Every time you sell an item, it pulls the cost for that exact unit (using average cost or FIFO) and books it as COGS for that sale. The total COGS is just the sum across every line item on every receipt — calculated instantly, not at month-end.

Stock value in real time

Your stock value at any moment is just: (units on hand × unit cost) summed across every SKU. Because your POS knows every purchase and every sale, the stock value number on the dashboard is always current — for every branch, every warehouse, every channel.

That's why a number like PKR 23,847,795 on the homepage dashboard is not made up — it's exactly what your inventory is worth right now.

Operating expenses, properly categorised

Rent, salaries, electricity, internet, courier charges, packaging — entered into your POS the same day they're spent, tagged with a category. At any point you can see the expense breakdown for the period: how much went to salaries, how much to courier, how much to rent.

This is what separates a real POS from a sales-only register.

Putting it all together — a worked example

A small Lahore clothing shop in one month:

  • Net Sales (after returns): PKR 2,489,301
  • Cost of Goods Sold: PKR 1,612,000
  • Gross Profit: PKR 877,301
  • Rent + Salaries + Utilities + Packaging: PKR 542,000
  • Net Profit: PKR 335,301

Every one of those numbers came directly out of the POS. No accountant phone call. No Excel spreadsheet. The owner could see net profit at any moment of the month, on any device.

Why this matters more than ever in 2026

Cost of stock is rising. Couriers are more expensive. Returns are higher than they've ever been. Retailers in Pakistan who can't see their real profit weekly are flying blind. The ones who can — and act on it — are pulling away.

FAQ

Does Revebe Digital track COGS automatically? Yes. Every purchase records the unit cost and every sale books the cost of the item sold, so COGS is calculated in real time.

Does it work for branches that share stock? Yes — Revebe Digital is multi-branch, so stock and COGS are tracked per branch and rolled up at the company level.

Can I see profit per channel — counter vs Shopify vs Daraz? Yes. Profit reports break down by sales channel, so you can see whether Daraz or Shopify is actually making you money after fees.
