The Billing section of the CaaS Portal covers program balance funding, invoice management, and deposit tracking. All monetary movements use USD as the settlement currency, funded via USDT deposits.

​
Program Balance

Your program balance is the central USD pool from which all card funding is drawn. Monitor it from the Dashboard widget or in Billing → Balance.
Cards cannot be funded when the program balance is zero. Set up the ACCOUNT_LOW_BALANCE webhook event to receive an alert when your balance falls below the configured threshold.

​
Funding the Program Balance

1

Go to Billing → Deposit

Click Billing in the sidebar then select Deposit Funds.
2

Choose a network

Select TRC20 (USDT on Tron) or ERC20 (USDT on Ethereum) and copy the deposit address.

Send USDT

Send USDT from your exchange or wallet to the deposit address. The amount is credited to your program balance after on-chain confirmation.
