Stashy — Home Inventory & Storage Organizer

What we’ve accomplished together

Households lose time and money when everyday items are scattered across closets, garages, and pantries with no shared record of what is stored where. The Stashy team set out to replace that chaos with a mobile-first inventory system shaped around how people actually live—custom places, named locations, and quick answers when someone asks, “Do we still have batteries?” Triaxo partnered with them to turn that vision into a production-ready app on iOS and Android.

To make that vision real, the platform had to deliver:

“From chaos to clarity—Stashy gives every household one organized place to find items, avoid duplicate purchases, and stay on top of low stock without spreadsheets or guesswork.”

Project Overview

Flutter Mobile App → Firebase Authentication → Cloud Firestore & Firebase Storage → RevenueCat (In-App Purchases)

Triaxo Solutions architected Stashy as a native-feeling Flutter application for iOS and Android, backed entirely by Firebase. User accounts are managed through Firebase Authentication with email/password, Google Sign-In, and Sign in with Apple. Inventory data lives in Cloud Firestore across four core collections—users, places, locations, and items—structured in a three-level hierarchy that mirrors how households think about storage: a place (such as a home or apartment), locations within it (kitchen pantry, garage shelf), and individual items with metadata.

The mobile experience is organized around a four-tab bottom navigation shell—Home, Search, Storage, and Profile—with a slide-out drawer for grocery list access, logout, and account deletion. The Home screen surfaces live dashboard metrics including total items, storage places, storage locations, and recently added items, with quick actions to add items or create new places. The Storage tab presents places in a swipeable carousel; each place card lists its locations with slidable edit and delete actions, optional location photos uploaded to Firebase Storage, and drill-down into item lists per location.

Beyond cataloging, Stashy actively supports restocking workflows. Each item supports a minimum quantity threshold; when current quantity meets or falls below that minimum, the item automatically appears on the Grocery List screen. Search uses Firestore prefix queries on a normalized name_lower field and enriches results with place and location names so users can find “batteries in the garage” in seconds. Onboarding captures six pages of household context—living situation, co-users, item types, rooms to organize, current organization level, and desired value—and persists responses to Firestore to personalize the first-run experience.

Monetization is handled through RevenueCat (purchases_flutter), integrated at app launch with user-scoped login and entitlement checks for “Pro Access.” Premium upgrade flows appear on the Profile screen and a dedicated subscription screen, with monthly and yearly packages loaded dynamically from RevenueCat offerings. Profile management includes photo upload, member invite UI, privacy policy and terms links, and full account deletion with Firebase re-authentication when required.

Why Triaxo Solutions

Triaxo Solutions brought deep Flutter and Firebase expertise to Stashy—from hierarchical Firestore data modeling and cascading deletes to RevenueCat subscription gating and cross-platform social authentication. The result is a polished, store-ready inventory app built on a scalable serverless backend, delivered without the overhead of custom API infrastructure.

“One app. Every item. Every shelf. Found.”
