I built a custom Inventory Management System in Microsoft Excel using VBA to help a small business track stock, orders, clients, and monthly performance without relying on expensive software.
The goal was to replace multiple messy spreadsheets with one centralized, easy-to-use system that updates automatically and reduces manual errors.
The Problem
The client was managing inventory manually across different Excel files, which caused:
Stock mismatches and missed updates
No clear view of stock in / stock out
Difficulty tracking monthly orders and client data
Time wasted on repetitive data entry
They needed a simple internal tool that non-technical staff could use daily.
The Solution
I designed a mini ERP-style system in Excel, powered by VBA automation, with clear navigation and connected modules.
π§ VBA-powered buttons and forms for easy data entry
π Structured tables ready for future reporting or dashboards
All actions (adding stock, placing orders, updating inventory) automatically update the system in the background using VBA.
Tools & Technologies
Microsoft Excel
VBA (Visual Basic for Applications)
Advanced formulas & structured tables
Result & Impact
β Reduced manual tracking errors
β Faster daily operations for staff
β Clear visibility of inventory status at all times
β One single file instead of multiple spreadsheets
β No monthly software costs for the business
The client now has a reliable internal tool that can scale as inventory grows.
Why This Matters
This project shows how Excel + VBA can be used to build powerful internal tools for businesses that want automation without complexity or high SaaS costs.
