Colonelserver Auto Credit Balance Notification

The Colonelserver Auto Credit Balance Notification addon automatically notifies your WHMCS clients when their credit balance falls below a defined threshold.
It helps prevent service interruptions by reminding clients to top up their accounts in time.

Key Features

  • Sends automatic email alerts when credit is low
  • Uses your selected WHMCS Email Template
  • Runs automatically via the Daily Cron Job
  • Clients can choose which contact email receives alerts
  • Admin tools for Dry-run and Force-run testing
  • Custom cooldown period to prevent repeated alerts
  • Fully compatible with WHMCS 8.x and PHP 7.4–8.3

How It Works

  1. Administrator sets the credit threshold and selects an email template.
  2. Each day, the addon checks all active clients.
  3. If a client’s credit is below the threshold, the addon sends the selected email.
  4. Clients can manage which contact email should receive notifications in their Client Area.
