Upsell and cross-sell service reminders (e.g., seasonal maintenance)

Purpose

1.1. Automate timely upsell and cross-sell reminders for air conditioning repair customers, such as seasonal maintenance offers, air filter subscriptions, warranty extensions, and advanced tune-up services.
1.2. Increase customer retention and average transaction value by delivering relevant follow-up notifications post-invoice/payment.
1.3. Ensure seamless, timely outreach to optimize both sales and customer experience based on previous service data, usage cycles, and seasonal needs.

Trigger Conditions

2.1. Invoice creation or payment confirmed for any HVAC repair job.
2.2. Time elapsed since last repair/service matches seasonal triggers (e.g., 3, 6, or 12 months).
2.3. Specific service types (e.g., coil cleaning, emergency repair) completed, identifying target product recommendations.
2.4. Customer lifecycle events flagged (e.g., warranty about to expire).
2.5. Conditional triggers: low engagement, prior declined offers, or specific parts replaced.
