Dashboard in Dark Mode - SaaS for Invoicing, Dunning & payment

The dashboard for Dundy, a SaaS for SMEs to help with invoicing, dunning and payment. Here, we tried a black version of the design which we ended up rejecting as the main design. It's nice as an option but B2B users tend to prefer screens with easier contrast; while very appealing in terms of UI, our user testing indicated that users had trouble locating ctas and getting jobs done.
