Problem

Client Background

Carblip needed a smoother app flow for high-intent buyer inquiries and dealer response workflows.

Critical Risk Area

Users were not moving from inquiry to deal quickly enough due to communication friction.

  • Slow buyer-dealer response loops
  • Low conversion after first inquiry
  • Limited in-app transaction guidance

Solution

Delivery Outcome

We optimized in-app inquiry workflows, notification triggers, and decision-stage guidance for buyers.

Why this approach

Marketplace conversion improves when communication speed and decision confidence are both strengthened.

Buyer inquiry flow

Dealer response workflow

Negotiation status tracking

Push-based re-engagement

Process

How we made key decisions, handled technical complexity, and applied engineering expertise to deliver measurable outcomes.

1

Product & Architecture Decisions

  • Separated communication and listing services for faster updates
  • Added stateful tracking for inquiry progression
2

Technology Selection Reasoning

  • iOS native performance for high-intent interactions
  • Node.js services for notification and state updates
3

Complexity Managed

  • Improved response visibility to reduce buyer uncertainty
  • Reduced inquiry drop-offs during negotiation stage
4

System Design Approach

Shipped core inquiry-response improvements first, then layered conversion nudges and status transparency features.
