Perth and Kinross Council were forced into a climb-down earlier this year after a care service fiasco saw elderly residents put into arrears.
One family was hit with an invoice for nearly £30,000, while many others saw their costs rise significantly.
Hundreds of vulnerable day-care clients across Perthshire received massive demands for back payments after the launch of a new “tailored service” policy sparked a system backlog.
Hit with a deluge of complaints, the local authority announced in April it had put a halt to all annual invoices and instead sent out explanatory notices outlining the new systems and explaining changes to costs.
Councillor Peter Barrett said this should have been done at the outset and said the council’s approach had been “ham-fisted” and insensitive.
The problem stemmed from the introduction of the so-called Contributions Policy, which went live last year.
The new system is designed to offer a tailored service to people using non-residential care, but led to a three-month backlog.
The biggest change is that charges for each resident’s entire care requirements are calculated, rather than costs per service.
A council spokeswoman said that extra resources had to be ploughed into clearing the backlog. Other action taken included improved communcations between departments and a more streamlioned approach to shorten the time it takes to send out invoices to clients and their families.
