  Here we debit the buyer for $110 ten times and on each debit we 
  add the sellers account URI in the meta field so that we know 
  which transactions belong to him.

  Finally we query the credits and debits using that meta data and 
  subtract the total åmount of the credits by the total amount of 
  the debits to get the current amount owed.
