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.
3

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.
