Mercari / BASE / Shopify / Rakuten / Amazon / Creema / minne …unify every channel and consolidate products, inventory, orders, customers, profit and journal entriesinto one place. A unifiedsales × CRM × bookkeeping OS for solo sellers and small businesses.
Cross-Channel
“Sold on Mercari,” “Booked on BASE” — capture them all in one place. Same product, same row: inventory, customers and profit are unified into one.
Scattered across 11 channels
Unified into one ledger
Supported (planned) channels
Concept
One order arrives. As “Flow,”it's an order; as “People,” a customer timeline; as “Money,” a journal entry — four ledgers stand up at the same instant.
Features
Inventory / orders / customers / bookkeeping / PWA / offline / audit log. Not bolt-on integrations — one screen, from the start.
Mercari, BASE, Shopify, Rakuten and every other channel share one stock count. Double-selling is structurally prevented.
Customer ledger is built automatically from order email/phone. LTV, repeat rate, and last purchase stay current with no extra work.
Every order generates the 3 entries (sales, fees, shipping) on the spot. Monthly P/L is one tap away.
Add to home screen, runs as an app. Offline orders save as drafts and resync when you come back online.
Product → channel → amount. Stock decrement, journal entries, and notifications all run in under a second.
Journal entries are append-only for audit safety. Corrections are reverse entries that preserve history. Full code audit log.
On a sale, other channels pause / allocate. Sync tasks retry with exponential backoff until they succeed.
Speak expense memos, customer notes, and order remarks. Stays fast even mid-delivery or in-store.
