I did a few enterprise sales, e.g. to Deutsche Post AG or Siemens, and I have to disagree to point 7 here. At first German companies do not sent a check in an envelope, but use Germans much better banking network for wire transfer. Unlike US direct debit and direct credit are free of charge and execute within a day between two banks, and nearly instant at same bank. The other thing about point 7 is a "trick" I learned more then 30 years ago: Offer 2% discount, if customer pays within 7 days. Everybody who can count will do, even enterprise.
