WHEN EVERY NEW LENDER
BROKE THE UI

The Context

Finbox partners with dozens of lenders, and every lender has a distinct onboarding DNA. One needs bank statements; another requires salary verification; a third mandates e-sign before KYC.

Adding a new lender meant engineers manually dragging fields into a Figma-like void and deploying code. Every new partner broke the UI equilibrium, leading to massive tech debt and slow rollout cycles.

The Solution: LMS Builder

We built a modular, block-based system that allows product teams to configure entire loan journeys without touching React.

Shifting the needle from "Ticket -> Design -> Code -> QA -> Deploy" to a single "Configure -> Preview -> Live" cycle.

CORE ONBOARDING
ENGINE

Tailored tab structure according to your loan profile

Design moveBefore you land in the builder, you choose a loan profile:
- Education loan
- Business loan
- Personal loan
- Loan against property
- Auto loan
Based on that choice, the builder surfaces preset tab suggestions, for example: - For a business loan: “Loan Details”, “Co‑applicant & KYC”, “Verification”, “Financials”. - For an education loan: “Applicant Details”, “Co‑applicant”, “KYC”, “Fee Structure”. You can accept, reorder, or add/remove tabs—so lenders never truly start from scratch, but they’re never boxed in either

  • Block-based design
  • Standardized inputs
  • Dynamic flow logic

THE BUILDER
CANVAS

Visual drag-and-drop journey management.

Problem: Every operations team had a different mental model of “what should come first”: details, risk, KYC, or documents. Your previous setup required devs to re‑order tabs and manually enable/disable them per lender. Design move
On the builder canva: Tabs are first‑class objects. Ops can drag to reorder them to match their workflow (“KYC before Verification”, “Co‑applicant after Application Forms”).
A drag-and-drop interface where product managers can visualize the entire lender journey. Reorder steps, add branching conditions, and preview changes in real-time.

  • Visual journey mapping
  • Live state preview
  • Drag-and-drop reordering

MODULAR PROP
MANAGEMENT

Contextual property control at block level.

Every block comes with a suite of configurable properties. Toggles, dropdowns, and text fields are linked directly to JSON keys, instantly updating the UI across all platforms.

  • Contextual properties
  • Rule-based visibility
  • Custom Validations

JOURNEY LOGIC
& DEPLOYMENT

Integrated versioning and environment control.

Integrated versioning and environment control. Product teams can prototype in staging, run A/B tests on specific lender flows, and deploy to production with zero downtime.

  • Instant push
  • Staging vs Prod
  • Version Tracking

WHAT CHANGED?

EFFICIENCY & VELOCITY
70%

Reduction in Dev cycles for new partner onboarding. Engineering effort shifted from "building" to "maintaining the builder".

COST IMPACT
~6k Hours

Estimated developer hours saved annually across 50+ lender integrations. This significantly reduced operational overhead.

SCALABILITY
10X

Capacity increase. Finbox can now onboard partners at scale without a linear increase in engineering recruitment.
