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.
Your shop page
Customers pay you directly with your PromptPay QR.
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
Which second-hand lines does KamraiDee cover?
Eight: clothes, bags & accessories, shoes & sneakers, gold, watches, furniture, electronics and toys. Each piece sits on its own line, so one stall can sell several lines.
How do I calculate the profit on a second-hand piece?
Take the price it sold for. Subtract what you paid, any repair, cleaning or inbound shipping on the piece, and the platform fee, ship-out and packing on the sale. What's left is the profit on that piece.
I bought a whole bale or a lot by the kilo. How is each piece costed?
Type what you paid for the pile and how many pieces it gave. Each sale takes an equal share of what's left of the pile's cost. If you haven't counted the pieces yet, the sale is saved as cash in, not profit, until you do. If you know what one piece cost, type that instead.
What happens to pieces I can't sell?
Log them as waste: damaged, unsellable or donated. Their cost shows as a loss in baht, kept as its own total next to the profit from your sales.
Does KamraiDee check if a piece is real, or price my gold?
No. KamraiDee doesn't check authenticity, grade condition, test anything or give a gold price. It keeps your own numbers and notes.
Is KamraiDee free for thrift sellers?
Yes. KamraiDee is free to join. Every shop type gets the same app. On a stall, you log what you paid for each piece or lot and keep a waste log in baht. You also get products with their profit, packaging included. Customers pay you directly with your PromptPay QR. See the pricing page at /pricing.
