Once you subtract every order-level cost you get net profit per order. But your business also has costs that aren't tied to any single sale — rent, salaries, software. Take those out too and you get operating profit: whether the business as a whole makes money. Both matter, for different decisions.

Net profit (per order)

Net profit = Revenue − COGS − fees − shipping − ad spend − returns

This is the profit tied directly to a sale — your true profit on that order. It answers: is this product, campaign or customer profitable?Sum it across a period and you have total net profit from orders.

Operating profit (per period)

Operating profit = Total net profit − operating expenses

Operating expenses (opex) are your fixed running costs — rent, wages, apps and tools, subscriptions. They don't move with a single order, so they only make sense over a period (a month, a quarter). Subtract them from your total net profit and you get operating profit: the real bottom line of the business.

Worked example

In a month you do 200 orders with $4,000 of total net profit. Your operating expenses — rent, one salary, apps — come to $3,200. Operating profit = $4,000 − $3,200 = $800. The orders are profitable, but the business only just clears its overheads — a signal to raise volume, lift margins, or trim fixed costs.

It's common for order-level profit to look healthy while operating profit is thin or negative — exactly the blind spot that makes a growing store feel busy but broke.

Which should you watch?

  • Net profit per order — to steer products, pricing and ad spend day to day.
  • Operating profit — to know if the whole business is viable, and by how much.
