How to Build an Inventory App with AI

Small businesses run inventory in spreadsheets that die on the warehouse floor. A phone app with barcode scanning and low-stock alerts is a genuine B2B product — and B2B means real subscription prices from few users.

What a inventory management app needs

  • Item catalog with barcode scanning
  • Stock in/out with quantity tracking
  • Low-stock alerts
  • Locations/bins
  • CSV import/export

The screens

ScreenWhat it does
ItemsSearchable catalog with stock levels
ScanBarcode scan → item, quick +/- stock
Item DetailHistory, location, reorder point
AlertsBelow-reorder-point list
SettingsLocations, export, team, billing

The data model

  • Item: name, barcode, reorderPoint, locationId
  • StockMove: itemId, delta, date, userId, note
  • Location: name

The build prompt (copy this)

Paste this into ShipNative and it becomes a working React Native app with these screens, navigable in a live preview, in about two minutes:

An inventory app for a small retail shop. Item catalog with barcode scanning (camera), stock in/out with movement history, reorder points with a low-stock alert list, locations, CSV export. Screens: Items, Scan, Item Detail with history, Alerts, Settings with team members. Per-seat monthly billing.

Then iterate with small, screen-specific prompts (“make the primary button bigger”, “add an empty state”), preview on your own phone, and export the full Expo project whenever you want. The full method: how to build an app with AI.

How it makes money

B2B per-seat or per-location ($15–40/mo). Ten shops beat ten thousand consumers.

Frequently Asked Questions

Does barcode scanning work in AI-generated apps?

Yes — camera-based barcode scanning is a standard Expo capability; prompt for it and the scan-to-item flow generates.

How do I sell an inventory app?

Directly — walk into shops in one vertical (bike shops, boutiques, cafés) with the app on your phone. Vertical focus beats generic "inventory for everyone."
