“We sold so much — where did the profit go?” The answer usually hides in hidden costs — small expenses that aren’t in the purchase price but add up to eat serious profit. Here’s a checklist to track them down.
What are hidden costs?
Hidden costs are expenses from selling and running the shop that you don’t include when working out product cost — which makes your “paper profit” look better than the real thing. (How this differs from gross/net: Gross profit vs net profit)
Checklist of common hidden costs
| Hidden cost | Examples |
|---|---|
| App/card fees | Delivery takes ~30% · card 1–3% |
| Bags/packaging | Bags, boxes, straws, cutlery, stickers |
| Waste/expiry | Vegetables, fruit, milk, pastries unsold in time |
| Free samples/giveaways | Freebies to boost sales, tastings |
| Trips to buy stock | Fuel, transport to market/deliveries |
| Hidden electricity | Fridges, freezers, AC running all day |
| Transfer/withdrawal fees | QR/PromptPay fees in some cases |
How much do hidden costs eat?
Say you sell via a delivery app: shelf price ฿100, cost of goods ฿40 — looks like ฿60 profit. But:
- App takes 30% = ฿30
- Box/bag = ฿5
Real profit = 100 − 40 − 30 − 5 = ฿25, not ฿60! Hidden costs ate more than half the profit you thought you had.
How to keep hidden costs under control
- Record every expense, even small ones — bags, fuel to buy stock, fees.
- Separate sales channels — app vs walk-in profit differs a lot; know which is worth it.
- Set fixed costs to deduct automatically — rent/electricity/internet entered once, deducted every month.
Posless helps here: snap a receipt to let AI read it as cost, type ad-hoc costs (like “cost bags 100”), and set fixed costs to auto-deduct every month → so you see real profit after hidden costs, not an illusion.
Frequently asked questions
Q: Do I really need to record tiny hidden costs? Isn’t it a waste of time? A: One is small, but a whole month isn’t. Use a tool to log them quickly so you don’t miss them or waste time.
Q: Do delivery-app sales lose money? A: You must build the fee into the app price (usually set higher than walk-in), or selling more just loses more.
Q: How do I count waste/expiry as a cost? A: Count it as money spent that earned no sales. Record it so you know if you’re over-ordering.
Summary: Missing profit usually hides in app/card fees, packaging, waste, travel, and hidden electricity. The fix is to record everything, separate your sales channels, and auto-deduct fixed costs — so you see real profit, not an illusion.
