Transaction, credit-ledger and Z-report tracking for a jeweller
Screenshots & Schematics

Problem & Challenge
Jewelers exposed to price slippage during volatile gold swings and unorganized customer credit accounts tracked on paper ledgers.
How It Works
Real-time gold bullion and coin prices stream with live ticker indicators.
Store managers set custom retail markups and toggle a clean customer-facing showroom view.
Customer loans and balances are recorded with dual denomination tracking (grams and fiat currency).
Scrap buy-ins, trade-ins, and retail sales feed into instant cash drawer tallies.
One-click end-of-day Z-reports render financial turnover and Recharts margin analytics.
Architecture & Technical Decisions
Next.js 16 (App Router), TypeScript, Recharts visualization library, central bank exchange rate integration, and Tailwind CSS v4.
