This David Roher applies for net terms , he order the goods, they get delivered . He has 30 days to pay for the invoices. Once it is due, he will avoid you at all costs. Takes expensive vacations , yet doesnt pay his debts.
He is a real debtor. DONT DO BUSINESS WITH THIS GUY. He has a terrible reputation with his own customers as well, if you are looking to get work done he will not honor warranties because he owes the suppliers money, and in turn you wont get honored.
