# How to purchase credits?

ReachBoost credit packages let you add monthly credits to your subscription. You can choose a credit package during checkout for a new subscription or add one later from your subscription settings.

### Add a credit package to a new subscription

**Step 1 - Select your credit package**
Choose the number of credits you'd like to receive each month while selecting your subscription plan.

**Step 2 - Complete checkout**
Finish the checkout process. Your selected number of credits will be allocated monthly.

### Add a credit package to an existing subscription

**Step 1 - Open your subscription settings**
Navigate to your Subscription page. https://app.reachboost.io/settings/subscription?tab=subscription

**Step 2 - Edit your subscription**
Click **Edit Subscription** to open the subscription configuration pop-up.

**Step 3 - Select a credit package**
Choose the credit package you'd like to add and confirm your changes.

**Step 4 - Start using your credits**
Your credits are allocated instantly and will continue to renew on your existing renewal date.

### Mid-cycle upgrades for quarterly and annual plans

If you add a credit package in the middle of a quarterly or annual billing cycle, ReachBoost invoices only the remaining months in your current billing period. Your renewal date stays the same.
