by buying 'credits' / 'funds' (which is what created the invoices), you top up the account balance (from which regular invoices for hosting can be deducted automatically) – that's the only way to do so. the 'due' invoice just disappears when you pay for it and turns into store credit, which probably can't be used for paying for more store credit as that would create some sort of vicious cycle
anyway they charge significantly higher processing fees for adding store credit, so i just prefer to pay each invoice individually as the fees are lower that way
tl;dr don't worry about it
