Browsing https://directory.fsf.org/wiki/Category/Business/accounting , I found https://www.odoo.com/documentation/user/9.0/accounting/others/analytic/usage...

GNUcash is not especially easy when it comes to analytic/project-based/activity-based/reclassified accounting: https://bugzilla.gnome.org/show_bug.cgi?id=113772#c6 / https://gnucash.uservoice.com/forums/101223-feature-request/suggestions/1543...

Other alternatives look less popular: * PBooks, * HomeBank https://answers.launchpad.net/homebank/+question/147356 .

Did someone test Odoo, or did someone manage to integrate analytic accounting in their GNUcash usage? https://meta.wikimedia.org/wiki/FLOSS-Exchange contains little information on accounting software used by the various entities.
