Interior design business software that runs the whole firm
Updated 25 Oct 2026
Interior design business management software runs the business side of a design firm in one place: leads, quotations and BOQs, projects, site updates, team roles, invoicing and payments. The D&B Operating System does this for interior design, architecture and design-and-build firms, on the firm's own domain. It doesn't draw your designs; it runs everything around them.
