Billing and Warranty Claim Process

Last Update 18/8/2022

Please find following a basic overview of the billing and available tariffs of MasterDC services. The last section also provides information on how to deal with incorrect billing or any service complaints. Please see our Terms and Conditions for more details.


Prices for agreed services are typically invoiced monthly according to the agreed tariff. Furthermore, the establishment of services may be subject to a set-up fee.

  • For services set up through sales representatives, the user pays a monthly flat rate in advance with a 14-day payment period. After that, a second invoice may be issued retroactively for any drawing on above-limit capacities.
  • For services set up automatically through Customer Administration, the user pays for the drawn services retroactively according to their use.
  • For specific types of services, the user pays a one-time fee.

The first invoice is issued on service activation date regarding the number of days remaining in the month.

You can also choose a different payment frequency (semi-annually, annually…) – whereby a discount will be applied to the charged amount.

Cloud Hosting Tariffs

Three billing options are available for cloud hosting customers – FIX, CONFIG, and LIVE.

  • FIX – We always issue an invoice on the first day of the month for the same month (in advance).
  • CONFIG – We charge according to the percentage of resources used; the customer sets the resources limit. One invoice is always issued on the first day of the month for the same month (in advance). The second invoice, which considers the overdrawn limit, is issued on the last day of the month (retroactively).
  • LIVE (Live Cloud) – We issue one invoice on the first day of the month for the same month (in advance) when the customer pays the flat rate. A second invoice is issued on the last day of the month, reflecting the actual usage of that month.

We support credit cards, PayPal, bank transfers, or direct debit. You can change the payment method according to your preferences in your profile settings under the Customer Administration > Edit Profile > Payment Options. Changes of this nature must first be submitted for approval.

Recurring Payments

By paying the first invoice, the customer agrees with the establishment and parameters of the recurring payment and the storage of payment data on the payment gateway site. The recurring payment for services will always occur once a month for the previous month or the entire period when the customer uses the operator’s services.

If you want to change the settings of the recurring payment or cancel a recurring payment, you can change the payment details by going to Customer Administration > Edit Profile > Payment Options.
