Manager for iMac Snow Leopard 6.8?

I have an old Imac which I want to use offline for my small business accounts.

Is there a way to get an earlier version of Manager? The current one needs 7 or later, I think.

Sorry - my OS is 10.6.8 and 10.7 is required for current version.

Major changes in the Mac OS occurred at 10.7. There is no backwards-compatible version of Manager.

Not sure if it would work for you but you could try Linux in a virtual machine such as virtual box and run manager in that.
