# Credit transactions

> Read the account Transactions ledger for allowances, purchases, content generation, and agent-run costs.

The **Transactions** ledger on the Billing page explains every addition to or use of the account's shared credit balance.

## Open Transactions

1. Open the account workspace
2. Select **Billing** in the account sidebar
3. Find **Transactions** beside the plan and credit controls

The ledger is visible to account members who can open Billing. Billing-management permission is still required to change plans or buy credit packs.

## Read a transaction

Each row shows:

* **Date** in UTC
* **Activity** that added or used credits
* **Details**, including the project when available
* A signed **Amount**

A positive amount adds credits. A negative amount spends or expires credits. Agent and other usage can include fractional credits, so the ledger can show more precision than the rounded balance elsewhere in the product.

## Activity types

The ledger can include:

* **Monthly allowance** and **Monthly allowance expired**
* **Credit pack**
* **Credit adjustment**
* **Content generation** and **Content generation refund**
* **Agent run pending**, **Agent run estimate**, and **Agent run completed**

The ledger keeps plan allowance and purchased credits in one account balance. Monthly allowance credits expire on the next billing anniversary. Purchased credit packs do not expire, and DevTune spends the expiring allowance before purchased credits.

## Agent run transactions

An agent run uses a reserve-then-settle flow:

1. **Agent run pending** reserves the estimated credits before the run starts.
2. When the run finishes, **Agent run completed** shows the final measured cost.
3. The pending estimate is marked **Replaced by final amount** and displayed with a line through it so it is not mistaken for an additional charge.

Select **View run** to open the corresponding agent run when its project is still available.

If a run is still active, the pending reservation remains labeled **Pending**. A final agent transaction is labeled **Settled**.

## Browse older transactions

Transactions display 20 rows per page. Use **Previous** and **Next** to move through older activity. The page indicator shows your position in the available history.
