Purchase on account with partial payment option (POWERPAY) As an external payment service provider, MF Group / POWERPAY offers the payment method “purchase on account”. With the individual invoice, you can easily pay for your online purchase by invoice. If you do not make a payment within the specified time frame, you will receive a monthly invoice with an overview of your order in the following month. When the purchase contract is concluded, POWERPAY takes over the invoice claim and handles the corresponding payment modalities. When purchasing on account, you also accept POWERPAY's GTC in addition to our general terms and conditions. (powerpay.ch/de/agb).
