# Monthly vs annual billing

*Understand the key differences between monthly and annual billing, including how domain slot charges work and when pricing is adjusted.*

DMARCeye offers both monthly and annual billing options so you can choose what fits your workflow and budget best.

Here’s how they differ:

## **Monthly billing**

* You pay once per month, based on the number of domain slots in use at the moment your billing cycle renews.
* You can freely add or remove domains at any time.
* The number of slots used on the renewal date determines the next month’s charge.
* Great for flexibility or short-term use.

> **Example**: You start with 3 domain slots. You remove one and add two during the month. At the next billing date, you’re using 4 domain slots — and will be charged for 4 domains.

## **Annual billing**

* You pay once per year based on your active domain slots at the start of the subscription.
* If you add more domain slots mid-year, you are charged a pro-rated amount for the remaining time.
* Ideal for teams who want to commit long-term and benefit from a discount.
* Lower cost per domain over time.

**Example**: You start with 10 domain slots. After 3 months, you add 2 more. You’ll pay a pro-rated amount for those 2 slots covering the remaining 9 months.
