# Kigu > Kigu is inventory and profit-tracking software for professional luxury-watch dealers. Track every watch by brand, model, reference, serial, condition and box & papers with photos; record sales with per-piece P&L after fees and expenses; use a linked-device WhatsApp connection so AI extracts listings (brand, model, reference, price, currency) from the dealer groups you choose and matches buy requests; and, on the Circle plan, see reference-level market price data. 30 currencies with stored exchange rates, 9-language interface, multi-user organizations. Pricing: Free plan $0 (up to 50 inventory items, 1 team member), Pro $59/month, Circle $199/month — no credit card required to start. Kigu is not affiliated with or endorsed by WhatsApp or Meta. Kigu is a back office, not a listing tool: it imports Chrono24 CSV exports and generic spreadsheets (one-time import, not a live sync), but it does not cross-list or auto-publish to marketplaces, and it has no consignor portal, webshop, POS, invoicing or repair tracking. The detailed links below are UTF-8 plain-text Markdown mirrors of Kigu's public pages. Each document identifies its canonical HTML source. Private inventory, contacts, transactions, organizations and account pages are never included. ## Use cases - [Inventory & P&L Software for Chrono24 Dealers](https://kigu.app/for/chrono24-sellers.md): Import your Chrono24 listings, manage them as one source of truth, and track true profit after Chrono24's commission.
