Bidcar
An online car auction — live lots, a bidding flow, user balance and an admin panel for operators.
// case.overview
The challenge
// problem
Buyers needed confidence to bid on cars they had not seen in person, and operators managed lots, users and payouts in disconnected tools.
// approach
I designed two sides of one product — a public auction for buyers and an admin panel for operators — on one shared component set.
// focus
Rich lot pages, a clear bid flow, a transparent balance and an admin dashboard with auction stats.
// case.work
Key screens
Four flows across buyer and operator.
Admin dashboard
Auctions, sales and commission for any period, plus lots awaiting buyout.
Active auctions
Live lots with photos, current bids and time left.
Lot page
Photos, specs and bidding history for a single car.
Place a bid
A focused bid step that shows the current price and your balance.
// case.mobile
On mobile
The buyer side adapted for phones: browse, inspect and bid with one hand.
Auctions feed
Live lots with photo, current bid and time left — bid or buy straight from the card.
Lot page
Price, bid step, deadline and deposit above the fold, actions pinned to the bottom.
Place a bid
A bottom sheet with a stepper, quick increments and a balance check before confirming.
