> Learn about the differences between multi-account and single-account configurations.
## Account configurations
Depending on your use case, you will have either a multi-account configuration or a single-account configuration.
In a **multi-account configuration**, we'll onboard an initial account for your business and provide you with an account ID. You'll then use our API to request an account for each of your customers. We'll run the necessary checks and once approved, you'll receive an account ID identifying your customer via webhook.
In a **single-account configuration**, we'll onboard an account for your business and provide you with an account ID. You'll then use our API to create a budget for each of your customers. This is a reliance model, which may not be available to you.
If you're unsure about which configuration you have, please contact your account manager.
