Method: 75 capabilities scored Included (1), Partial (½) or Not verified (0) from public vendor and third-party evidence; evidence coverage = (included + ½ × partial) ÷ 75. WindoorERP was checked against installed modules on live tenants, and an unpublished roadmap counts as absent for every system. "Not verified" is not proof of absence — corrections welcome.
