Free Quota

The free quota would be renewed when the new financial year starts (i.e. the next round of fee quota would be renewed and valid from 1 Jul 2022 – 30 Jun 2023). Current users’ platform charges would be automatically deducted the amount of free quota ($ 5,000) when the charges are over $5,000 and receive an invoice for the settlement of outstanding charges. For new users, they will enjoy the free quota and be charged when the amount exceeds $5,000. Each current and new user’s free quota would be renewed when the next financial year starts from so on. As such, users don’t need to inform us when and how the free quota be used to settle the payment since the final amount to be charged would automatically deducted the free quota assigned to users accordingly.
