I'm coming to this late
I'm coming to RTI rather late in the day, but a friend who runs a small business and whom I occasionally help (for free) has asked me to explain RTI to him and help him with set up. In his case it will be relatively easy in practice as he has no staff turnover (the same half dozen employees have been with him for over a decade) and he has full names, addresses, NINOs, etc even for the cleaner (2 hours per week). Just one payroll, run monthly. Everybody on a (pretty) fixed monthly salary (plus occasional overtime hours). No oddities like SMP - not even a student loan in sight.
But I do wonder how some other employers are going to cope with this (and other changes on the horizon).
In a perfect world it would run great - but in the real world . . .
I foresee payrollmageddon!! Or perhaps a return to the old days - cash in hand, no paperwork!
