### ✨ Key Features

#### 📬 Email Templates and Notifications

The Invoice Module comes with pre-configured and customizable email templates that automatically notify tenants of billing events:

* **New Invoice Notification**
  * Automatically triggered when a new invoice is generated (e.g., during signup or plan renewal).
  * Includes invoice details, due date, and a secure payment link.
* **Plan Expiry Warning**
  * Sent to tenants before their current plan expires (customizable number of days before expiry).
  * Encourages early renewal to prevent suspension.
* **Overdue Invoice Reminder**
  * Sent when an invoice is past its due date.
  * Includes updated payment link and consequences of non-payment.

#### 🧾 Automatic Invoice Generation

* An **invoice is automatically generated** when a tenant signs up from the pricing page and selects a plan.
* The invoice includes:
  * Plan Name
  * Trial Period (if applicable)
  * Price and Billing Frequency
  * Due Date
  * Available payment methods

#### 🛒 Online Payment Integration (Stripe & PayPal)

* Accept **secure online payments** directly from invoices using:
  * ✅ **Stripe**
  * ✅ **PayPal**
* Tenants can access invoices by email.
* Payments are **automatically verified** and applied to the tenant's account.

> 💡 Once payment is received, the plan is activated or renewed immediately, and the tenant receives a confirmation email.

#### ⛔ Automatic Tenant Suspension (After Expiry or Overdue Payment)

* Tenants who fail to:

  * Pay an invoice **by the due date**
  * Or **renew** their plan before it expires

  will be **automatically suspended**.
* During suspension:
  * The tenant loses access to the CRM system.
  * All data remains safely stored but locked.
* Access is **restored instantly** upon payment.
