A construction materials marketplace raises RFQs to its vendor network — steel, cement, aggregates — and those vendors submit rates back. The existing flow was four mobile screens: the offer request, rate entry per line item, review with totals and GST, and a confirmation. It worked. That was all it did.

Rate submission is the highest-value action a vendor takes on the platform, and the brief was to make the experience reflect that: restructure the screens, merge them, change the visual language, or keep the structure and layer motion over it — but ship the version you would actually want to use. The weight went on the small moments. Input states, the transitions between steps, what moves and why it feels good, and the submit moment itself, which is the one beat a vendor remembers.

The deliverable is not a picture of a flow. It is the flow — running below, on this page. Open it and quote something. Under it sits the system it was built from: 70% neutral concrete and paper tones, charcoal for commitment, and yellow held back as a signal rather than spent as a background.
