PLUMB — Business Banking Console

Money, considered. Not gamified, not a terminal.

A working demo of ALO's LEDGER finance vertical on the CONCRETE register: a living ledger, an event-bus cascade, review-before-you-send with Confirmation-of-Payee, and a programmable-money rule builder. A fictional bank — no real institution, no real money moves.

PLUMB is the flagship of ALO's LEDGER vertical rail — money-truth, trust, and transaction encoded as tokens rather than left to per-page improvisation. PLUMB occupies the empty quadrant: dark, editorial, anti-gamified, calm.

The build pairs LEDGER's semantic money axis — debit as neutral ink, failure as the only red, nothing as color alone — with the CONCRETE register's Swiss precision, so the ledger, the tables, and the API surfaces read with zero translation loss between "the system is visible" and "the work is precise."

The interface runs on a mock client-side ledger: a running-balance feed, an operating-balance monument that appears fully formed, an event-bus cascade, a review-before-you-send flow, and a programmable-money rule builder.

Restraint governs the transactional core; a dynamic, eclectic infographic layer carries the ALO signature elsewhere — the two never trade places.

The Challenge

Before the rebuild.

Consumer fintech is bright and playful; wealth swings between gamified confetti and terminal overload; B2B is indigo Stripe-clones on an 8-degree mesh. The empty quadrant — dark, editorial, anti-gamified, calm — had no build proving ALO could hold trust through a transactional core.

The System

Proof that money can feel considered — restraint in the interface, expression in the infographic, and never the two traded.

What’s Built

The Ledger — running-balance feed, tabular numerals aligned on the decimal
The Monument — operating balance as the one loud figure, fully formed, never counting up
Event-bus cascade — one simulated purchase updates balance, feed, and notification at once
Review-before-you-send — recipient echo, Confirmation-of-Payee tri-state, full fee breakdown
Semantic money axis — debit is neutral ink, failure is the only red, never color alone
