Finventory — Cloud Inventory & Accounting SaaS

A subscription-based SaaS platform that helps factories and trading businesses manage inventory, sales, purchases, and accounting in one cloud-connected system.

Ali Nawab Rana / Finventory Manufacturing & Trading / Inventory Management SaaS 12-16 Weeks One platform for stock, billing & ledgers
Project Overview

Finventory is a subscription-based cloud SaaS platform built for factories, printing presses, warehouses, and trading businesses in Pakistan. It replaces scattered Excel sheets, paper challans, and separate billing tools with one connected system for sales, purchases, stock, ledgers, tax-aware invoicing, and analytics — all synced to the cloud with multi-company workspaces and role-based access.

The product supports the full operational cycle: sales orders → delivery challans → invoices → payments → party ledgers, with raw material and finished goods tracking, production readiness analytics, PDF exports, and subscription plans. Owners, managers, operations staff, and accountants each get the access level they need without maintaining separate systems.

The Challenge

What We Were Up Against

Disconnected spreadsheets

Sales, stock, and accounts lived in separate Excel files with no real-time sync or audit trail.

Paper challan workflow

Delivery challans and invoices were manual, causing stock mismatches and delayed billing.

Multi-company complexity

Business owners needed separate datasets per company with shared login and plan limits.

Tax & compliance gaps

Sale tax, further tax, NTN/STRN, and filer/non-filer rules had to appear correctly on invoices.

No role-based access

Managers, ops, and accountants all needed different permissions on the same data.

The Solution

How We Solved It

Cloud SaaS architecture

Firebase-backed multi-tenant platform with Auth, Firestore, Storage, and subscription billing.

End-to-end workflows

Orders, challans, invoices, returns, and payments linked in one operational flow.

Smart stock engine

Finished goods and raw materials update on sale/purchase with trader mode and vendor-based options.

Integrated accounting

Party ledgers, receivables/payables, day book, trial balance, and ageing reports.

Production Readiness analytics

Scales raw material requirements to a base production quantity with vendor or generic stock matching.

Branded PDF exports

Invoices, challans, ledgers, and reports with company logo and professional layout.
