The invention makes it easier for the post office to calculate accurately terminal dues for business reply mail by providing information to the post regarding each piece of business reply mail that crosses an international border. The foregoing is accomplished by charging a sender's meter for business reply mail that is being deposited with a first carrier; transmitting the funds charged to the meter to a meter data center; transmitting from the meter data center to a first carrier meter payment center the funds attributable to the first and second carriers; and transmitting from the first meter payment data center to the second meter payment data center the funds attributable to the second carrier.
