# Usage Credit
Give usage credits to your clients in cloud marketplaces
---
## Overview
ISV sellers can offer usage credits (in amount, default currency USD) to their clients (buyers) in the active Entitlements of all marketplaces. It provides flexibility for your sales or revenue operation team to customize deal & incentives.
:::danger
- The Suger Usage Credit is applicable `ONLY` for usage-based metering. If the Entitlement has no usage-based metrics defined, the Usage Credit has no effect at all.
:::
:::warning
- If your current metering service supports the credit, don't use it together with Suger Usage Credit, otherwise it may result in double credits.
:::
## Billing Priority
Credit is just one of multiple available incentives. For example, In Azure Marketplace, each metering metric can have included quantity or even infinite included quantity. In GCP Marketplace, the metric may have free tiered quantity. In addition, some Entitlements are type of commit + usage-based combined, which has commit amount to consume. To eliminate confusion, they are ordered by their billing priorities in the table below. The `Suger Credit` is consumed first, then `Commit`, and the `Included Quantity` is the last.
| Priority | Incentive | Description |
| --------- | --------- | ----------- |
| 1st | Suger Credit | Applied first to incoming usage records, in the order they are received by the Suger metering API, until the credit amount is used up. |
| 2nd | Commit | Applicable if the `Entitlement` has commit amount (for AWS & GCP) or Flat_Rate (for Azure) |
| 3rd | Included Quantity | - AWS Marketplace: Not applicable
- Azure Marketplace: Included Quantity or Infinite Included
- GCP Marketplace: Tiered Free Quantity
|
### Worked example
Assume a usage-based metric priced at $1/unit, on an entitlement with $30 Suger Credit, a $20 commit, and 10 units of Included Quantity. A usage record of 100 units ($100) is offset in priority order:
1. **Suger Credit (1st):** $30 of the $100 is covered by credit. Remaining: $70.
2. **Commit (2nd):** $20 of the remaining $70 is drawn from the commit amount. Remaining: $50.
3. **Included Quantity (3rd):** 10 units (= $10) are covered by included quantity. Remaining: $40.
The buyer is billed the remaining **$40**. (Figures are illustrative.)
## Add Credit
There are two approaches to add credit to the Entitlement: Suger Console or Suger API.
:::warning
- The Suger Usage Credit amount must be `positive`.
:::
:::warning
- You are only allowed to add the Usage Credit amount via the Suger Console or API. There is no way to revert or decrease the amount. If you would like to decrease the Usage Credit amount for any reason, please contact us at support@suger.io for support.
:::
1. **Suger Console**
Go to the page of Entitlement where you want to add the credit, and scroll down to the section of `Entitlement Terms`. Click the button `Add credit`, select the target Entitlement Term (optional), input the credit amount in the dialog and submit.

2. **Suger API**
Use the [addEntitlementCredit REST API](https://doc.suger.io/api/add-entitlement-credit) to add the credit amount. The request payload would be like:
```json [Payload of addEntitlementCredit request]
{
"organizationID": "your-suger-organization-id",
"entitlementID": "suger-entitlement-id",
"entitlementTermID": "suger-entitlement-term-id", // Optional
"creditAmountIncrement": 100.0,
}
```
The success response would be:
```json [Payload of addEntitlementCredit response]
{
"organizationID": "your-suger-organization-id",
"entitlementID": "suger-entitlement-id",
"entitlementTermID": "suger-entitlement-term-id",
"creditAmountIncrement": 100.0,
"newCreditAmount": 150.0, // new total credit amount, assume there was $50.0 before addEntitlementCredit.
}
```
