Built for the way you actually work

Two records every trader needs first: what you have, and what you sold. Everything else follows.

Inventory tracking

Know exactly what you have, down to the last item. Stock counts update automatically every time you record a sale or restock.

  • Live stock levels for every product
  • Low-stock alerts before you run out
  • Batch tracking — see which stock arrived when
  • Buy in packs, sell as singles or packs
  • Search and filter by name or stock level

Sales recording

Record a sale in seconds. Revenue and profit are calculated automatically — no mental maths, no separate calculator.

  • Add multiple items to a single sale
  • Automatic revenue and profit calculation
  • Track sale channels (walk-in, WhatsApp, online)
  • Link sales to saved customers
  • Print or share receipts instantly

Customer & debt tracking

Save regulars, track what they owe you, and mark debts as paid when they settle. No more guessing who owes what.

  • Save customer names and phone numbers
  • Track outstanding debts per customer
  • Mark debts as paid with one tap
  • See total owed and who owes it
  • Link sales and returns to customers

Analytics & reports

See your numbers clearly. Know your best sellers, your profit, and how your week is going — at a glance.

  • 7-day revenue chart
  • Top product by units sold
  • Average spend per customer
  • Total revenue, profit, and expenses
  • Export everything to CSV or Excel

Returns & refunds

When a customer brings something back, record it properly. Move the item into returned stock or discard it — you decide.

  • Record refunds with a reason
  • Hold returned items in a separate list
  • Add returned items back to stock
  • Track return history
  • Refunds automatically counted in expenses

Expense tracking

Log business costs that aren't stock — transport, rent, data, anything. Everything adds up in one summary.

  • Log expenses with a description
  • Stock purchases counted automatically
  • Refunds tracked automatically
  • Total spent summary at a glance
  • Everything exportable for your records

Your data is protected

Your business records are private. Here's exactly how we keep them safe — in plain language.

Encrypted in transit

Every bit of data between your device and our servers is encrypted using HTTPS/TLS. Nobody can eavesdrop on your sales or stock records.

Private cloud workspace

Your records live in your own isolated database row. Other users can never see your products, sales, or customers — period.

Row-level security

Database-level rules ensure every query is automatically scoped to your user account. Even a bug in the app cannot leak another shop's data.

Breach-checked passwords

When you create an account, your password is checked against known data breaches. We only send the first 5 characters of a hash — your password never leaves your device.

You control your session

Choose "keep me signed in" or not. If you don't, your session ends when you close the tab. Sign out remotely from any device at any time.

Export anytime

Your data is never locked in. Download your products, sales, expenses, and customers as CSV or Excel whenever you want.

Built on enterprise-grade infrastructure

inventri runs on Supabase, which is built on top of PostgreSQL — the same database technology trusted by companies like Netflix, Instagram, and Spotify. Row-level security, automated backups, and encrypted connections come standard.

One simple plan. Everything included.

No tiers, no confusing feature gates. One price gives you access to every feature in inventri.
