# Billing And Pricing

DIDWW primarily operates on a prepaid billing model. Customers requiring a postpaid billing arrangement should contact
their sales representative at [sales@didww.com](mailto:sales%40didww.com) or account manager. Postpaid billing requests
are subject to review and may be approved on a case-by-case basis under a separate agreement.

The minimum top-up amount is 30 USD, and a sufficient positive balance must be maintained to keep your services active.

Supported Payment Methods:
:   - **Credit Card** - Real-time top-ups via the User Panel.
    - **PayPal** - Manual or automatic balance refills. To enable, contact: [billing@didww.com](mailto:billing%40didww.com)
    - **Wire Transfer** - Manual payments only. Processing time varies depending on bank.

All payments are processed in **USD**, while **EUR** is also accepted for Wire Transfer and PayPal transactions.
Customers should ensure that their chosen payment method supports transactions in their preferred currency.

Note

- Third-party transaction or currency conversion fees (e.g., bank or PayPal charges) may apply and are the customer's responsibility.
- Only net amounts received will be credited to the DIDWW account balance.

Services are automatically renewed unless canceled by the customer. When Credit Card or PayPal is set as the preferred
payment method, the prepaid balance is automatically refilled to maintain service continuity. Wire Transfers must be
initiated manually and are not eligible for auto-replenishment.
