maint & mon invoiced in march, still open on the ledger
subscriber is reluctantly willing to pay the mon but not the maint until we have do the visit
I'm happy to do this today, they don't want anyone on site
can not understand they are receiving the principal benefit which is service on demand
the other issue is we invoice them in the due month, rather than waiting until we'd done the job,
they sold their co. for a few million & like to moan at me about a couple of hundred quid
people think I'm a bitter man, but to be honest I prefer a lager
