Sixty seconds, no narration: the 20% that turns out to be 10.32% once you try to
restock, the suggested price that puts the shelf back the way it was, and the
health chip that tells you whether a product is still worth selling.

📖 The story
It's 9pm and Reza is pulling down the shutter. He sold ten shawls today, each at 20% profit,
and he's pleased. He bought them three months ago at 400,000 toman each.
The next morning his wholesaler calls: prices are up. Only now does he realise that the money
from those ten shawls will not buy ten shawls. His profit looked like 80,000 each — but
restocking the same shawl now costs about 442,203. Of that 20%, roughly 8.55% is
actually left.
That is the moment Sooda is built for. Reza enters his purchase and selling price, and next to
the nominal profit Sooda shows the real profit — flagged as thin, with a suggested price
that covers buying the goods again.
That afternoon a customer wants a 10,000,000 item on instalments. Reza opens
"Is my deal profitable?" and finds that the flat 2%/month he has always charged now barely
breaks even — a 0.12% loss, which is to say he is working for free. He fixes the number, and
sends the customer a payment schedule with no mention of his own margin.
And the imported item priced in dollars? Sooda estimates a monthly price-growth rate for each
product separately — and tells him where that number came from.

- Open Sooda — no install, no sign-up.
- Under Profit %, enter Purchase price 400,000 and Desired profit 20.
- Tap Calculate.
Selling price 480,000 · Profit 80,000.
That's it. The rest of this guide is about what Sooda does beyond that.
🎓 Interactive tutorial
When is it for? The first time you open Sooda, and any time afterwards that you want to
learn a part of it. There is nothing to read — you work on the real buttons.
What to do
- On first run, Sooda offers a short exercise; tap "Let's work it out together".
- Later, open the "Learn Sooda" card in Settings.
- Start any lesson you like — and tap "Skip" whenever you want.
Example — the first exercise: Reza bought a shawl for 100,000 and wants 20% profit. Four
taps later you see that if the same shawl sits on his shelf for three months, that 20% on paper
is really under 10%. The whole thing takes about a minute.
Tip — all of it happens in a practice shop: five sample products made only for the
lesson and deleted when it ends. Your own products, prices and history are never touched. If you
get stuck, "Show me" does the step in front of you.
There are eight lessons — profit percentage, discounts, real profit, instalments, products,
smart rates, everyday use, and backups — each 50 to 90 seconds. Each ends with a small question,
marked by Sooda's own calculation engine, and a wrong answer is never called wrong: you just try
again.
📘 Step-by-step guide
🧮 Profit %
When you need it — you know what you paid and want to sell at a set margin.
What to do — open Profit %, enter Purchase price and Desired profit, tap Calculate.
Example — a 400,000 shawl at 20%: selling price 480,000, profit 80,000.
Tip — that's the nominal profit. For what's left after restocking, use the real-profit lens below.
🏷 Selling price
When you need it — a price is already on the item and you want to know the margin.
What to do — open Selling price, enter Purchase price and Selling price, tap Calculate.
Example — bought 400,000, sold 480,000: 20%, i.e. 80,000.
Tip — a loss is flagged in words as well as colour ("You're losing money at this price."),
never colour alone.
🎁 Discount & reverse discount
When you need it — running a sale, or working out what the original price was.
What to do — open Discount (or Reverse discount), enter the price and the percentage, tap Calculate.
Example — 15% off 480,000: final price 408,000, saved 72,000.
And back the other way: a 408,000 price that was 15% off started at 480,000.
Tip — reverse discount is the quick way to check an advertised "70% off".
💸 Real profit — "When does your money come back?"
When you need it — always. This is the heart of Sooda.
What to do
- In Profit % or Selling price, open When does your money come back?
- Pick when the money returns: Now, 1 month, 3 months, 6 months or 12 months.
- If you already know the new purchase price, choose I know the current purchase price;
otherwise leave Estimate with inflation.
Example — the 400,000 shawl sold at 480,000, money back in 3 months:
| |
|---|
| Monthly inflation | 3.4% |
| Restock cost (estimate) | about 442,203 |
| Real profit | about 8.55% — thin |
| Suggested price | about 530,644 |
Tip — the default inflation figure comes from the Statistical Center of Iran and can be
changed in Settings. If your wholesaler has quoted you a new price, enter that instead — it
beats any estimate.
