Daily gold rates, GST-correct billing, and old-gold exchange — built for how Indian jewellers actually work.
A multi-tenant SaaS platform modeled around Indian jewellery retail: daily-fluctuating gold/silver rates, making charges and wastage on top of metal value, old-gold exchange with a white/black cash split, bullion-specific GST, and Aadhaar-based KYC for high-value purchases. A tenant can run multiple physical stores from one account.

Gold/silver/platinum rates are immutable and insert-only — every change creates a new chained record, giving a full audit trail and guaranteeing old bills stay pinned to the rate in effect that day.
Metal value and making charges are taxed separately (3% vs 5%, configurable), split into CGST/SGST or IGST with an asymmetric rounding rule so the two always sum exactly to the total.
Trade-in rows capture weight, purity, purchase rate and value, split into white (accounted) and black (off-book) categories, totaled separately on the bill.
Aadhaar numbers are AES-256-GCM encrypted at rest — only the last 4 digits are ever returned on a normal read; full decryption is Owner-only, rate-limited, and audit-logged.
Per-item tag/HUID, purity, weight and stone details, with a full status lifecycle — in stock, sold, on approval, melted (linked back to its source bill), or lost.
Automated payment-due, overdue and pickup reminders over SMS/WhatsApp, plus sales, day-book, GST-filing and inventory valuation reports with CSV export.
Owner or manager locks in gold, silver and platinum rates each morning — billing is blocked until they do.
Line items pull from real inventory or are entered ad hoc; trade-in old gold is automatically split white/black and taxed correctly.
Partial payments across cash, UPI, card and bank transfer, pickup status per item, and automated reminders keep every bill moving.
Day book, GST summary, dead-stock and valuation reports are ready whenever the store needs to reconcile or file.
We can license this platform for your business, or build something similar tailored to your needs. Let's talk.
