Many shop owners know their sales number but still feel unsure about profit. That is usually because sales, cost of goods, expenses, returns and stock value are mixed together in the owner's head.

COGS and profit and loss are not only accounting terms. They are practical tools for answering one question: after selling products and paying costs, is the business actually making money?

What COGS means

COGS means cost of goods sold. It is the cost of the products you actually sold, not the cost of everything you purchased.

If you buy 100 pieces at Rs. 1,000 each, your purchase value is Rs. 100,000. If you sell 30 pieces, your COGS is Rs. 30,000. The remaining Rs. 70,000 is still stock value, not an expense of the sold items yet.

Simple gross profit formula

Gross profit = Sales - COGS

Example:

  • Sales: Rs. 90,000
  • COGS: Rs. 55,000
  • Gross profit: Rs. 35,000

This tells you whether your products are priced well before rent, salaries, delivery, software, internet and other expenses.

Gross profit is not net profit

A shop can have healthy gross profit and still lose money after expenses. Net profit is what remains after operating expenses.

Net profit = Gross profit - Expenses

If gross profit is Rs. 35,000 and daily expenses are Rs. 18,000, net profit is Rs. 17,000. If expenses are Rs. 40,000, the same sales day becomes a loss.

The mistake many shops make

They treat cash as profit. Cash in the drawer includes product cost, supplier money, taxes, delivery collections and sometimes customer advances. If you spend that cash without separating profit from obligations, the business feels busy but becomes short on payments.

Why stock value matters

Stock is money sitting on shelves. If your POS knows purchase cost and current quantity, it can show stock value. This helps you avoid overbuying slow items and underbuying fast ones.

A shop with Rs. 2,000,000 in stock but weak cash flow may not be healthy. The stock may include dead items that are hard to sell. Reports should show both inventory value and movement.

Reports to check every week

  • Sales by product: which items create revenue.
  • Gross profit by product: which items actually make money.
  • Expense summary: where cash is going.
  • Stock value: how much money is tied in inventory.
  • Slow-moving stock: what needs discounting or promotion.
  • Supplier balances: what must be paid soon.

What a POS needs for accurate profit

Profit reports are only as good as the data behind them. Make sure purchase cost is entered correctly, returns are recorded properly, discounts are included, and damaged stock is adjusted. If staff can sell products without cost data, profit reports will be incomplete.

FAQ

Can I calculate profit without tracking expenses? You can calculate gross profit, but not true net profit.

Should owner withdrawals count as expenses? For clean reporting, separate business expenses from owner drawings. Mixing them makes performance hard to understand.
