Work

Six projects: what they do, what they are built with and what I measured. Where a client stays anonymous, I show a sketch instead of screens.

    A sketch instead of screens: the client stays anonymous.

    Quotes, work orders, invoices, planning, a shared inbox and the accounting in one system. Used at the front desk, in the workshop and by the owner.
