Tea & Coffee Supply Manager — Free Excel to Web App Conversion | Browser-Based Tracker with Login, Dashboard & CSV Export

Tea & Coffee Supply Manager — Excel to Web App Conversion By Subham Ghadge | Subu Data Labs | Office Automation & Web Tools | July 2026 Version 4.0 Excel + Web App No Server Needed 100% Free localStorage Role-Based Login In almost every corporate office, pantry supplies like tea and coffee machines require continuous monthly tracking. Administrative staff need to monitor milk carton usage, coffee bean orders, stirrer counts, and tea bag consumption, then cross-charge these costs accurately to participating companies or internal departments. Traditionally, this tracking happens inside a shared Excel spreadsheet. While Excel works initially, managing multiple users, concurrent access, user permissions, and month-end vendor reports over email becomes slow and prone to formatting errors. To solve this, I converted our master Excel tracking workbook into a standalone, browser-based web application. It...

Personal Finance Tracker | Excel Budget Planner & Expense Management System

📅 Published by Subham Ghadge | Category: Financial Analytics, Excel Templates, Personal Finance | Free Download Excel Arrays Budget Planner Data Privacy Personal Finance & Budget Analytics Tracker in Excel Checking your bank statement at the end of the month tells you where your money went, but it doesn't help you plan where your money should go. Relying only on delayed bank SMS alerts makes it easy to overspend and fall into credit card debt or zero savings. While mobile budget apps promise to track your expenses automatically, many demand full read access to your SMS messages, upload your financial data to cloud servers, or lock basic features behind monthly subscriptions. To keep my financial data completely private and offline, I built the SUBU Personal Finance Tracker in Excel. It tracks multi-bank account balances, monitors daily expenses against budget targets using SUMIFS formulas, and calculates your true monthly...

Property Rental Management Excel Template: Income & Tenant Tracker

📅 Published by Subham Ghadge | Category: Real Estate, Financial Modeling, Property Management | Free Download Excel Dashboard Rent Tracker Asset Management Real Estate Rent & Property Income Tracker in Excel Managing a multi-unit property portfolio—whether residential apartments or commercial spaces—requires keeping careful track of cash flow. When landlords and property managers rely on fragmented WhatsApp messages, paper notebooks, or scattered bank statements, tracking rent payments quickly becomes confusing. Keeping track of partial rent payments across multiple tenants while calculating electricity sub-meter readings manually often leads to missed dues and billing arguments. Without a clear tracking system, property owners lose sight of their true net rental income and struggle to compile clean records for annual tax filings. To solve this, I designed the Panchwa Rent Income Analysis System in Excel. It consolidates l...

Conference Room Booking System Excel Free Template

📅 Published by Subham Ghadge | Category: Facility Management, Office Administration, Excel Analytics | Free Download Excel VBA Resource Allocation Data Architecture Conference Room Booking & Calendar System in Excel (VBA) Managing meeting rooms and conference spaces in a busy corporate office can get chaotic fast. When different teams rely on verbal promises, whiteboards, or unorganized chat threads, double-booking is almost inevitable. Two departments end up showing up for the main boardroom at the exact same time right when an important client presentation is about to start. Buying expensive corporate room-scheduling software isn't always necessary for managing office meeting spaces. What facility managers need is a simple, central system that locks room choices, prevents scheduling overlaps, and gives everyone clear visibility. To solve this, I designed the Conference Room Booking System in Excel. It uses data validatio...

Free Sales Performance Dashboard Power BI Template India

📅 Published by Subham Ghadge | Category: Business Intelligence, Data Analytics, Corporate Strategy | Power BI DAX Sales Analytics Data Architecture Sales Performance Power BI Dashboard & DAX Analytics As a business grows, tracking regional sales performance across thousands of transactions using traditional Excel spreadsheets can quickly become slow and frustrating. When spreadsheets get bloated with thousands of rows and complex `VLOOKUP` or `SUMIFS` formulas, files freeze, calculation lags occur, and getting clear answers takes too long. While Excel is great for quick tracking, enterprise-level sales reporting requires a proper relational data model that can compress large datasets and update interactive reports instantly. To solve this, I designed the Corporate Sales Performance Power BI Dashboard . It replaces heavy flat spreadsheets with a clean Star Schema data model, uses Power Query (M Language) for automated data c...

Vehicle Customer Tracker Excel System | CRM, Sales & Order Management

📅 Published by Subham Ghadge | Category: Automotive Operations, Showroom Workflow, Excel Templates | Free Download Excel System Dealership Tools Data Validation Vehicle Customer Tracker & EV Dealership System in Excel In an automotive dealership or vehicle showroom, customer booking details often get scattered across multiple places—the main corporate CRM logs the initial booking, sales consultants write accessory choices in personal notebooks, and promised delivery dates are discussed over messaging threads. When the stockyard team prepares a vehicle chassis for final customer delivery under tight deadlines, piecing together this scattered information often leads to mistakes—like a missed accessory installation or an incorrect EV charger dispatched with the vehicle. To solve this operational friction, I created the Vehicle Customer Tracker System in Excel. It connects customer bookings, vehicle variants, accessory add-ons...
