Concept

One dataset,
four lenses to view it.

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.

  • Inventory is never UPDATEd directly — managed via the ledger pattern
  • Customers are auto-generated from order email/phone
  • Journal entries are immutable; corrections are reverse entries that preserve history
  • RLS + multi-tenant isolation on every table

Features

Everything a solo seller needs, from day one.

Inventory / orders / customers / bookkeeping / PWA / offline / audit log. Not bolt-on integrations — one screen, from the start.

Single central inventory pool

Mercari, BASE, Shopify, Rakuten and every other channel share one stock count. Double-selling is structurally prevented.

Auto-generated CRM

Customer ledger is built automatically from order email/phone. LTV, repeat rate, and last purchase stay current with no extra work.

Automated bookkeeping

Every order generates the 3 entries (sales, fees, shipping) on the spot. Monthly P/L is one tap away.

PWA / offline ready

Add to home screen, runs as an app. Offline orders save as drafts and resync when you come back online.

3 taps to confirm an order

Product → channel → amount. Stock decrement, journal entries, and notifications all run in under a second.

Immutable journal

Journal entries are append-only for audit safety. Corrections are reverse entries that preserve history. Full code audit log.

Instant cross-channel sync

On a sale, other channels pause / allocate. Sync tasks retry with exponential backoff until they succeed.

Voice input

Speak expense memos, customer notes, and order remarks. Stays fast even mid-delivery or in-store.

How it works

One order in, five things move.

The instant something sells on Mercari, here's what happens inside UriUri.

Why UriUri

How is this different from existing software?

Sales-first integration

Order, ship, adjust stock — journal entries form on the spot. Bookkeeping isn't bolted on later.

CRM × Operations fused

Customer LTV sits next to your P/L. See "profit contribution from your top 20% customers" in one view.

Mobile-complete PWA

Offline order drafts, voice input, add to home screen. Don't lose orders just because the signal dropped.

FAQ

Frequently asked.

Common questions on categories, supported channels, data import, plant sales and accounting.

Who is UriUri for?
Solo sellers and small businesses selling across multiple channels — Mercari Shops, BASE, Shopify, Creema, minne, Rakuten, Amazon, and more. Works for any category: handmade, used goods, plants, apparel, food, etc.
How is this different from a spreadsheet?
Inventory, orders, customers, revenue, profit and journal entries all flow from the same data. Confirm an order and central stock decreases, profit is visible, and the customer ledger updates — no jumping between sheets.
Can it sync inventory across multiple shops?
Yes. The central inventory pool unifies stock across every channel. For one-of-a-kind items the default policy is 'pause other channels on sale,' so you can list everywhere without risking double sales.
Does it work for handmade artists?
Yes. UriUri is built with creators in mind who sell across Creema, minne, BASE, Instagram and in-person. Manual order entry is optimized for fast input.
Can I sell plants with it?
Yes. UriUri is well suited for plants, seedlings and pots — manage stock, orders, customers and profit in one place. Pair it with Cropnode (cultivation OS) via REST API to take an individual plant from cultivation through to sale and profit, end to end.
Is this accounting software?
Strictly speaking, no — it is a sales-management ledger for inventory, customers and profit. Journal entries are generated the moment an order, shipment or stock action happens, so the data is ready to feed into your accounting software.
