Honestly, I don't know..  I suspect the best approach would be to look
at it from the other side.  Figure out what information you need to
compute payroll and write the code that computes that.  Then we can
figure out where to store the necessary information.  Also keep in mind
that Gnucash's payroll system needs to handle more than just US payroll.
(This is where the payroll plugins come in).

Specifically, yes, I can see where you might need to extend GncEmployee
to store information about the employee's salary/rate and payroll types,
and potentially even per-person deduction information.  There is no
"GncBusiness" object; the business information is stored in the book itself.
So, no, nothing to extend there.

I don't know enough about payroll systems to know whether you need an
industry type -- I would think that you could just create appropriate
plugins for various tables and just use a reference to the table in
the data file to know which one to use.  But that's why I think it would
be best to start by figuring out how to compute the payroll and then
work backwards towards object extensions.

I think further discussions should be on gnucash-devel.  You should subscribe
there and follow-ups to this message should go to -devel and not -user.
