What needed solving.
The background
Résacar is a platform connecting people who need group transport with coach operators, currently in development: a quote comparison tool, a partner area and a booking funnel.
The constraint
On a marketplace, value comes from comparability. Yet two coach quotes are almost never comparable: one includes the driver's meal, the other does not; one charges for standby time, the other by the kilometre. Without standardisation, the comparison tool compares nothing.
The response
Impose a single quote format on every partner: the same line items, the same inclusions, the same calculation method. The operator fills in a grid, not free text. It is more demanding at sign-up, and it is the only way to make the comparison honest.
Every design choice, and the reason for it.
A standardised quote grid
Identical line items for every operator, explicit inclusions. The customer compares rows, never paragraphs.
A request in several steps
The request is split into short steps with visible progress. On a long form, showing progress is what separates abandonment from completion.
A partner area designed for life on the road
Operators reply from a phone, between two jobs. The reply interface fits on one screen.

Every amount uses tabular figures: a comparison tool whose price columns do not line up is unreadable, and therefore useless.

A typed quote model
The quote grid is a schema validated on the server. A non-compliant quote is rejected on entry rather than corrected after the fact.
Notifications for both sides
A new request on the operator's side, a new reply on the customer's side. On a marketplace, response time is the metric that decides whether the service survives.

Comparison searches
“Compare coach quotes”, “group bus hire prices”. The intent to compare is exactly what the product promises.
