Yes, it is.
To pay for multiple children with one payment, the parent simply has to sum up the payments and add either their names or invoice numbers to the payment. PS: if paying for more than one child, reference numbers should not be used.
If children's names and/or invoice numbers have been added, our system will automatically divide the payment sum between correct players. Club has to confirm the pairings between invoices and payments and, if necessary, has the possibility to edit them.
