As the world's largest producer of postage meters, Pitney Bowes puts it stamp on managing mail. The company, nearly a century old, makes other mailing equipment and provides shipping and weighing systems and it offers online postage services, and financing for office equipment purchases. PB also develops software to create mailers and manage shipping, transportation, and logistics for government agencies and corporations. The company gets the majority of its revenue from small and medium-sized businesses (SMB). The company counts 1.5 million customers in 100 countries, but as mail volumes fall, so have PB's sales.
