If you want to add funds to your account, you need to login to your account and click on Balance.

Then you will see an option to add money to your account. The minimum sum is 10 USD.

Funds can be added to the account only when the account is active for at least 30 days on our system and there is at least one successfully paid invoice.

So if you see this message “Attention! Add funds is not available for your account”, it means that 31 days have not passed yet and you cannot add money to your account. In this case, invoices should be paid manually.
