Window and Door Estimating Software Built on Soft Tech V6
Step into the next generation of V6. Darley Designer is window and door estimating software developed by Darley Aluminium in collaboration with Soft Tech. We built it around real feedback from Australian estimators and fabricators, and designed it for speed, accuracy and efficiency, so you can produce more quotes and win more work.

Faster Quoting for Window and Door Fabricators
Every minute spent on a quote is a minute not spent winning the next job. Darley Designer removes the pain points that estimators have lived with for years. Navigation is quicker, workflows are smarter, and the interface stays clean and simple, so you can turn quotes around faster and lift your team's productivity.
Built on Soft Tech V6, Redesigned for Estimators
Darley Designer takes the proven Soft Tech V6 platform, trusted by window and door professionals around the world, and rebuilds the estimating experience from the ground up. We asked fabricators what they needed, what they didn't, and what slowed them down. Then we built a modern, streamlined platform around the answers.
