Don't just get a system specifically for CQC.
CQC has gone through several major changes and more keep coming every year, your system will be out of date virtually every year.

You should look for systems based on National Standards and accepted best practice rather than the latest list of prompts.
Core standards of the industry do not actually change that much, they evolve slowly. A system that follows core standards will remain future proof for many years.

Any decent compliance system should be able to cope with regular changes, without any upheaval or changes in the way you work.
A good acid test is to ask what happens if new and completely revamped KLOEs come in time after time, and whether that means you have to reorganise or do anything differently.

The only change worth making is to keep simplifying everything
