# Charge Monthly Plans

> When and how to use a fixed monthly fee, retainer, or monthly package instead of pure per-minute billing.

## Overview

A monthly charge gives you predictable revenue and gives your client a predictable bill. Vapify supports this two ways: a flat **monthly subscription fee** stacked on top of per-minute billing, or a **monthly package** with included minutes and overage.

## When to choose this

* The client wants one predictable number on their card each month
* You want recurring base revenue independent of call volume
* The client's usage is fairly consistent month to month

## The path

1. Read [Pricing Models](/billing/pricing-models) for the exact mechanics of both the subscription-fee and package approaches.
2. In the sub account's **Billing** tab, either set a **Monthly Subscription Fee** alongside your per-minute rate, or configure a **Voice Package** from **Billing & Usage → Subscription Settings** with included minutes and an overage rate.
3. Decide your overage rate carefully. See [Profit Tracking](/billing/profit-tracking) to keep even overage minutes profitable.
4. Communicate the model clearly to the client before go-live: what's included, what triggers extra charges, and when the monthly charge renews.

<Tip>
  Combine both: a monthly retainer for guaranteed base revenue, plus per-minute billing for any usage beyond what the retainer implies. Different clients can run different combinations.
