# Overview


Exe.dev billing has two parts: a flat monthly subscription, plus extra charges if you go over bandwidth or disk usage. An active subscription is needed to create and manage VMs.

Each plan has different price points (known as tiers) that map to the number of resources available to your VMs. We currently offer four tiers: small, medium, large and extra-large. As you scale your applications, you can upgrade or downgrade your tier based on your needs.

All subscriptions are paid for in advance meaning you are paying for the month ahead. We bill for usage at the end of each cycle, charging you for what you actually used.
