# Balance and subscriptions

Open **Balance** to manage subscriptions, account funds, and transaction history.

## Manage subscriptions

Review each subscription's type, status, available quantity, validity period, assigned bot or integration, renewal, and automatic-renewal setting. To add a subscription, choose its type and term, review the current price shown in the interface, and confirm. Assign an active subscription to the required bot or integration.

## Top up the balance

Open the balance tab and select the top-up action. The current balance and spending information are shown on the same page. An available balance does not replace an active subscription, so check both before launching a bot.

## Review transactions

Use the date, operation-type, and purpose filters to inspect top-ups and charges. Apply the filters before exporting the matching rows to Excel. For the cost of individual conversations, use the export on **History**.

Processing cost depends on the selected model, instruction size, conversation history, connected knowledge, action inputs and outputs, and response length. Remove duplicated instructions and provide only the context the bot needs.

## Launch complete

Return to [**Testing and processing history**](<./test-bot.md>) and send a final message through the real channel. If the expected reply arrives and History shows no error, the bot is ready.
