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.

1

Log any kind of purchase.

You can buy by the kilo, by the bale, or one piece at a time.

2

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.

3

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.

4

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

Brown leather loafers beside white sneakers, close up
Example · made-up numbers

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 do I work out the profit on a resold pair of sneakers?

Take the price the pair sold for. Subtract what you paid, any cleaning or repair, and the platform fee, shipping and packing on the sale. What's left is the profit on that pair. KamraiDee shows it for each pair you sell, from numbers you type.

Which selling channel leaves me the most on a pair?

Compare one pair across channels with the Selling fees by channel calculator at /tools/channel-fees. Its fee numbers are starting numbers from September 2026, not official platform rates, so change them to your own. In the app, profit is also shown by channel or venue.

Can I note the size and the box?

Yes. Shoe pieces have a US size, an EU size and a "box with the pair" flag, all as your own notes. KamraiDee doesn't give a size chart.

I bought used shoes wholesale by the sack. How is each pair costed?

Type what you paid for the sack and how many pairs it gave. Each sale takes an equal share of what's left of the cost. Pairs that can't be sold can be logged as waste, and their cost shows as a separate loss in baht.

Does KamraiDee check if sneakers are authentic?

No. It doesn't check authenticity or grade condition. Any condition you record is your own pick.
