Finventory — Firebase Cloud Backend for Multi-Tenant ERP

A cloud-backed inventory and accounting system using Firebase for authentication, real-time data, file storage, and subscription management across many companies and users.

Ali Nawab Rana / Finventory Cloud ERP / Firebase SaaS 8-12 Weeks (backend + app integration) Secure multi-company cloud sync
Project Overview

Finventory runs on a Firebase cloud backend — Auth, Firestore, Storage, and Cloud Functions — delivering secure multi-tenant inventory and accounting for many companies and users without on-premise servers.

Company-scoped data, role-based security, subscription billing via web checkout, and real-time sync power sales, stock, ledgers, and analytics. Production Readiness reads live inventory across vendors or generic material matching — all from the shared cloud layer.

The Challenge

What We Were Up Against

No on-premise option

Clients needed cloud-hosted data without IT infrastructure.

Multi-tenant isolation

Multiple companies and sub-users on one Firebase project safely.

Security & roles

Owners, managers, and staff needed strict read/write rules.

Subscription billing

Plans, trials, and limits without client-side subscription forging.

Document storage

Company logos and PDF-related assets in secure cloud storage.

The Solution

How We Solved It

Firebase suite

Auth, Firestore, Storage, Functions for full backend.

Multi-tenant schema

users/{uid}/companies/{companyId} scoping for all collections.

Security rules

Firestore & Storage rules mirroring workspace access.

Real-time sync

Live streams for inventory, ledgers, and dashboard metrics.

Plan limits

Subscription plans with enforced company/item limits.

Cloud analytics

Production Readiness pulls live RM/FG stock from Firestore.
