Difference between kintone licensing/plugins/seats and the new system, plus opportunities lost to slow quotes.

Challenge

kintone was easy to deploy but split lead, site survey, quote, order, construction, and aftercare into separate apps—forcing constant navigation to see one project. Photo handling was weak, and per-seat pricing scaled linearly with headcount.

Approach

Designed a renovation-tuned data model threading every stage under one project, built on Lays-Lop in 3.5 months. kintone data migrated losslessly.

Implementation

Site survey photos can be captured and organized from the project detail view. The quote screen auto-calculates pricing from a parts master and surfaces similar past projects. A homeowner aftercare portal is included to retain maintenance work.

Results

Monthly cost halved versus kintone + plugins + seats. Quote prep time fell 65%, and faster turnaround lifted win rate by 8 points.

VOICE

No more bouncing between apps. Seeing the whole project in one screen feels obvious in hindsight—but it was revolutionary for us.
