The　development　of　a　new　generation　of　information　technology　and　the　construction　of　information　infrastructure　have　not　only　led　to　a　rapid　increase　in　enterprise　productivity,　but　also　become　a　revolutionary　driving　force　for　the　transformation　of　enterprises　to　smart　enterprises.　The　cloud　service　platform　for　smart　small-micro　enterprises　researched　and　designed　in　this　paper　solves　the　troubles　of　traditional　manual　recording,　heavy　and　inconvenient　information　aggregation.　It　is　a　kind　of　small-micro　enterprise　with　multi-organization,　multi-tenant,　heterogeneous.　The　intelligent　cloud　service　platform　with　features　such　as　foreign　land　can　promote　more　small-micro　enterprises　to　join　the　ranks　of　informatization.
