Eight second-hand lines in one app
What do you sell?
Sell more than one line? Each piece sits on its own line, so one stall can carry several.
Why it helps
Know what each piece cost you and what it earns.
Log any kind of purchase.
You can buy by the kilo, by the bale, or one piece at a time.
Each piece gets its share.
Every sale from a kilo or a bale takes an equal share of what's left of the pile's cost.
Profit on each piece you sell.
This is the sold price minus what you paid, any repair or cleaning, and the fees on the sale.
Where it sold best.
See your profit by channel or venue: online, market, shop or a named event, picked when you log the sale.
What you track
Four things you track
Pieces
What you paid, plus any repair, cleaning or inbound shipping as extra cost.
Lots
A kilo or a bale, what you paid and how many pieces it gave.
Sales
The sold price, plus the platform fee, ship-out and packing you type.

Example: a lot of 20 jackets (made-up numbers)
Twenty jackets from one lot can earn very different amounts

You pay ฿2,000 for a lot of 20 jackets and count them. Each one gets an equal share of the cost: ฿100. A denim jacket sells online for ฿1,200, so the profit on that piece is ฿1,100. An everyday jacket sells at the market for ฿250, so it earns ฿150. Now you know which kind to look for next time.
Doubling your money isn't a 100% margin
Price from margin, not markup
Margin is the share of the sold price you keep after the true cost. With made-up numbers, a piece bought for ฿100 and sold for ฿200 is a 100% markup but a 50% margin. Fees and packing come off first.

FAQ
Second-hand profit questions, answered plainly
How many grams is one baht of gold?
Gold bar weight: 1 baht = 15.244 g. Jewellery weight: 1 baht = 15.16 g. One salueng is a quarter of a baht.
What can I record about a gold piece?
The weight in grams, the stamped purity (999, 965, 900, 800, 750 or unknown), the hallmark, the piece type, the metal and the weight basis (as weighed, as stated, or unknown). They are your own notes, not an assay, and they show only on gold pieces.
What does the profit on a gold piece include?
The price it sold for, minus what you paid, minus any extra cost on the piece, minus the platform fee, ship-out and packing you type on the sale. KamraiDee shows that profit for each gold piece you sell.
Does KamraiDee give a gold price or test purity?
No. It doesn't supply a gold price and doesn't assay gold. You type the price. The Gold melt value calculator at kamraidee.com/tools/gold-melt works out a melt value from the weight and the price you type.
How do I see my margin on a gold piece?
Log what you paid for the piece, then log the sale. Margin is the profit on that piece divided by its sale price, so you see the margin on each piece when it sells. KamraiDee never tells you the gold price to charge.
