### Where to find invoices

* Client Area → Invoices
* Direct link (may require login): <https://prevps.com/clients/clientarea.php?action=invoices>

### Payment flow (typical)

1. Open the invoice.
2. Choose a payment method.
3. Complete payment.
4. Re-open the invoice and confirm it shows as paid.

### Invoice timing, reminders, and late fee

These are our current billing timings. They can change later.

#### Invoice generation

* Invoices are generated **14 days before** the due date.

#### Reminder emails

If reminder emails are enabled, the typical schedule is:

* **Unpaid reminder:** **4 days before** the due date.
* **Overdue reminder #1:** **2 days after** the due date.
* **Overdue reminder #2:** **1 day after** the due date.
* **Overdue reminder #3 (final):** **disabled**.

#### Late fee

* A late fee can be added **1 day after** the due date.

{% hint style="info" %}
If you already paid but still receive a reminder, re-open the invoice and check its status first. If it still shows unpaid, open a ticket with the invoice number.
{% endhint %}

#### Automatic payment capture (cards)

For supported card payments, the system may try to capture payment **1 day before** the due date.

#### Payment reversals (chargebacks / disputes)

If a payment is reversed, the system may:

* Change the **invoice status** (back to unpaid), and/or
* Change the related service **due date**

#### Overage / metered billing (if applicable)

If your service has usage-based charges, overage is typically calculated at the **end of the month**. It may generate a separate invoice, or be added to the next invoice.

### Paying with credit balance (optional)

If you keep a credit balance, you can pay invoices without running a separate payment each time.

Typical flow:

1. Add credit to your account: <https://prevps.com/clients/clientarea.php?action=addfunds>
2. Enable **Auto Credit Balance** (so credit is applied to unpaid invoices).
3. Re-check the invoice status after it generates.

### If an invoice looks wrong

Open a ticket and include:

* Invoice number
* Screenshot of the totals
* What you expected (renewal, upgrade, promo)
