Common area maintenance Charges/Utility billings

Hi,

1. Pls suggest a best practice to charge a CAM charges to client without a CAM expense recovery add on module in REFX.

Through seperate REFX contract type for CAM or Service charge settlement.

If it is through REFX Contract/SCS, then how??

2. Second, Pls suggest the best practices to charge utility billing to client. (Electricity they use, Water they use in rented area).

BR,

Subbu.
