In light of the TID rollover, is the vending system supplier (or prepaid meter manufacturer) allowed to charge a cost on the utilities (users) to pay for the software system upgrade to meet the TID rollover standard 5.6 of STS1800-3 ?? 

we believe, during the global TID rollover program,  any upgrades for this rollover should be free and is the responsibility of the supplier.

Please clarify on this. 

thank you
