VBA / Excel Macros Process Optimization

Transforming a fully manual, error-prone Word document process into a dynamic, automated database system at Creative Computers.

The Problem

  • Invoicing was entirely manual using MS Word.
  • Data had to be entered twice (Word + Database), doubling the workload.
  • High susceptibility to human error during data entry.
  • Lacked proper financial traceability and credit tracking.

The Objectives

  • Remove Redundancy: Eliminate repeated manual typing.
  • Auto-Calculation: Automatically generate invoice numbers, totals, and VAT.
  • Digital Storage: Save invoices directly to local directories as PDFs.
  • Financial Tracking: Visually track unpaid invoices and highlight outstanding credit.

System Architecture & Workflow

01
Data entry officer selects a new row in the database. The current date fills automatically, and the user selects Sale or Repair (S/R).
02
On the VAT_Invoice interface, clicking Generate creates the next sequential invoice number, resets old fields, and fetches customer data automatically.
03
User enters item details. The system automatically calculates totals and VAT without manual math.
04
Clicking Add pushes the financial calculations back into the master database. Save generates a PDF, and Print sends it straight to the hardware.
05
Visual Database Logic: Rows turn green when payment is pending. Once credit hits zero, the row reverts to white, making debt tracking instant.
