I would never pay for that sort of reporting, and believe it's likely to be seen as a way of "gaming" the system. The industry cracked down on use of AUs for the same reason.
Some lenders (NACA for mortgages for example) will use proof from bank statements, landlords, utility bills, etc. in lieu of credit reporting. And one of the CRAs is trying to build another business gathering and reporting this sort of data. But services that take an outrageous fee ($96.00 a year) to report payments sound like a bad idea to me.
