Installation Steps

Download the installer file (BusinessLedger-Setup-2.0.0.exe)
Run the installer — Windows may show a security warning (see below)
Follow the prompts — Accept the license, choose install location
Launch Business Ledger from your desktop or Start menu
Enter your license key in Settings → License

⚠️ Windows Security Warning

Because our software is new, Windows may show "Windows protected your PC" warning. This is normal for software from small developers.

To proceed:

Click "More info"
Click "Run anyway"

The software is safe — we just haven't purchased an expensive code signing certificate yet.

Why USB sync? Your customer data never touches the internet. No cloud accounts, no data breaches, no subscription fees. Just plug in and sync — like the old days, but better.

Where Is My Data Stored?

C:\Users\[YourName]\OneDrive\BusinessLedger\

This folder contains:

Tip: If you use OneDrive, your data is automatically synced to the cloud as a backup!

Save your Recovery Code — Write this down! It's the only way to recover access if you forget your PIN
