Flip watches with real numbers, not spreadsheet guesses
You know your last flip made money. Kigu tells you how much, after fees and shipping — and which references actually earn their hold time.
TL;DR
Kigu is inventory and profit software for part-time watch flippers graduating from a spreadsheet: log every buy and sell with fees and expenses for true per-flip profit, keep the photos, condition and box-and-papers details that make relisting faster, track repeat counterparties as contacts, and import your existing sheet by CSV. There's a free plan (up to 50 items, no credit card), so trying it costs nothing.
Watch flipping starts innocently: one good buy, one clean sell, a row in a spreadsheet. Then it's six pieces in play, deals in two currencies, fees you keep forgetting to subtract, and a sheet you no longer trust. Reseller guides put the breaking point at around 20+ active listings (CoListable); most flippers feel it sooner.
Gross profit is a vanity number
Bought at 6,200, sold at 7,000 — feels like 800. Subtract the marketplace commission, shipping both ways, insurance and the strap you threw in, and the real number is closer to 500. Kigu logs each flip as a transaction with buy price, sell price and every fee and expense attached, so per-piece profit is the after-fees number. Before you commit to a buy, sanity-check the deal with the free watch margin calculator — then record the actuals in Kigu.
Know how long your money sat in each piece
A flipper's constraint is float, not shelf space. Because every transaction records when you bought and when you sold, you can see which references turned in days and which locked up your capital for months — and let that shape the next buy instead of a hunch.
Bring the spreadsheet with you
Kigu's CSV importer has a column mapper, so core watch and buy/sell fields come in without retyping. Still happy on a spreadsheet for now? Fair. Grab the free watch inventory spreadsheet template — its identity, condition, box-and-papers, transaction, currency, status and notes columns map into Kigu. Spreadsheet-only fees, asking price, location and formula outputs stay in the sheet.
Flipping through WhatsApp groups?
Dealer groups have long been where hot references get flipped — Watchonista documented flippers offloading via WhatsApp group messages at markups around 70% over retail on hyped models (source). Kigu connects to your own groups and AI-extracts the listings scrolling past — see Kigu for WhatsApp watch traders.
Full-set details that speed up the next sale
Condition, box-and-papers status and photos live on every piece, so relisting doesn't start with a hunt through your camera roll. Counterparties become contacts with deal history — useful when the same two dealers keep buying your Tudors. And with 30-currency support and stored exchange rates, a cross-border buy doesn't quietly corrupt your math.
If flipping turns into dealing
Plenty of flippers wake up one day as dealers. The system doesn't need to change: Kigu scales into multi-user organizations, period reports for the accountant, and channel workflows like the Chrono24 dealers setup. When you're weighing the jump, our guide on starting a luxury watch dealing business covers the practical steps.
Built for the part-time flip
Frequently asked questions
Is Kigu overkill for a part-time flipper?
No — there's a free plan at $0 forever with up to 50 inventory items, basic transaction tracking, one team member and email support, no credit card required. Fifty items covers most part-time flippers with room to spare; Pro ($59/month) exists for when you outgrow it.
Does Kigu auto-import my marketplace sales or calculate platform fees?
No. You log transactions yourself and enter fees as expenses — Kigu doesn't pull sales from eBay or Chrono24 automatically, and it doesn't auto-calculate each platform's commission inside a transaction. The free Chrono24 fee calculator and watch margin calculator are separate tools for estimating before you deal.
Is there a mobile app?
No native iOS or Android app. Kigu is web software that runs in your browser, including on your phone.
How is Kigu different from generic reseller apps like Flippd or Flip?
Those track flips across any category — sneakers, cards, whatever — and neither is watch-specific (as of July 2026 — verify with the vendors). Kigu is built around the fields a watch flip actually turns on: reference, serial, condition, box and papers — plus WhatsApp group ingestion with AI extraction. Generic trackers don't know what a full set is.
Can I start on the spreadsheet template and switch later?
Yes. The free watch inventory spreadsheet template maps its core watch and buy/sell fields into Kigu in one upload. Fees are not imported as transaction expenses, while asking price, location and the formula outputs remain spreadsheet-only.
