# How much does CAASie cost?

The fantastic news is that sign-up is free! CAASie is designed to be entirely self-service, so there are no management or subscription fees associated with your account.

CAASie sells space on digital boards on a cost-per-play(cpp) basis.

This means that your account is only charged at the time your ad plays. If your ad does not play, you will not be charged.

To make sure you have the appropriate spend available for the space at the time it should play, CAASie charges accounts using pre-paid credit. This is handy for a few reasons:

* No unexpected charges
* Set and forget
* Easy spend tracking

CAASie also offers automatic top-up for those who want to stay on top of their budgets. After your account credit lowers to a certain level, your account will be topped up in order to continue your campaigns.

### How much do plays cost on CAASie?

Each board you choose will have a different cpp (cost-per-play), which can fluctuate with time, placement and demand. Expect that a large billboard in the middle of a metropolis will cost more than a small billboard in a rural town. Prices can range from $0.05 to $10 or more.

CAASie gives you guides and price references during your [board selection](/boards/adding-boards.md#how-does-hand-selecting-boards-work) process to assist with managing your budget. You can also check out CAASie’s [cost calculator](https://caasie.co/costestimator) to give you a starting reference.

CAASie has a number of handy built-in tools and automatic calculations to help you make the most of your budget.

Some media owners have imposed a minimum campaign spend on some of their inventory. You can read more about that [here](/billing/minimum-spends-on-caasie.md). 

### What if I have no credit on CAASie?

If you run out of credit, your campaign will stop playing.

If your campaign is still live when you top up your credit, your campaign will resume playing your ads automatically. You can stop a campaign from spending credit by pausing it.

Your ads will also stop playing if your campaign budget has been reached.

### What is the minimum spend on CAASie?

The CAASie platform itself does not have a minimum spend; however, $80 is the minimum amount an account can top up its credit in a single transaction.

This credit is free to use in any number of campaigns, but keep in mind that an extremely low budget will be very limited in the number of ads that will play. The less available budget, the less your campaign can spend per ad play.
