Sorry I didn't explain that very well.  Hopefully this will shed a
little more light on this.

Text properties is an emacs feature where you can add extra (invisible,
and temporary) data to text in an emacs buffer.

An Org-mode properties are part of the org file and normally lives in
the :PROPERTY: drawer.

The column view overlay is displayed using emacs text properties - and
this doesn't alter the data in the org file.  Thus the org-invoice.el
code that queries the _org_ property CLOCKSUM never gets a value.

I think the fix is probably to make org-invoice.el look for the CLOCKSUM
text property instead of a CLOCKSUM org-mode property value.
org-invoice.el should probably also automatically call org-clock-sum so
this doesn't need to be a manual step.
