Safe & Vault (IN_STOCK)

High-security bullion and finished stock locked overnight in the branch vault.

All inventory not actively displayed on counter trays rests inside the safe. High-value bridal sets, 24K bullion bars, and reserve trays remain isolated and require an audited vault-out document to move to the counter.

Unvarnished Ground Truths

A few things
you might be
wondering.

Answers to common questions regarding dual-ledger metal accounting, karigar ghat limits, and offline resilience during festive showroom rushes.

Grams & LedgerWhy do we need a Dual Ledger instead of just tracking Rupees in Tally or Vyapar?

In a jewellery business, the value of gold fluctuates constantly while the physical grams remain constant. If a karigar or customer owes you 50 grams of 22K gold, tracking that debt in rupees exposes you to bullion price volatility and creates unresolvable "joda-panna" reconciliation disputes. Ratnivo keeps two independent ledgers in parallel: a milligram-precision Pure Metal account (BIGINT) and a Rupee financial account (paise), ensuring you know exactly how much metal and money every party owes you at any moment.

Karigar & WorkshopHow does Ratnivo track and prevent gold leakage with Karigars?

When you issue gold to an artisan on a digital Jangad memo, Ratnivo records the exact gross weight, issued purity, and agreed melting loss (ghat) tolerance by category (e.g. casting, filigree, handmade chains). On receipt, the finished pieces and scrap are verified on connected 0.001g scales. Any unexplained variance exceeding the agreed tolerance is routed immediately to the dispute queue rather than quietly written off.

Billing & POSHow fast is counter billing on a crowded festive day like Dhanteras?

Ratnivo Dukaan is optimized for high-volume counter checkout. Placing an item on your connected weighing scale and scanning its barcode tag automatically reads the gross weight, deducts stone weights, applies current gold rates, computes making charges, and calculates the 3% GST split — all in under 15 seconds. Invoices can be shared instantly via WhatsApp or printed on thermal receipt printers.

Migration & SecurityCan we import our existing inventory and party balances from Online Munim, JSoft, or Excel?

Yes, absolutely. We provide guided import templates for existing balances, customer lists, party masters, and opening stock. Additionally, every Pro and Trade showroom receives hands-on onboarding through our Ratnivo Saathi team, who will assist in configuring your thermal tag printers, pairing weighing scales, and shadow-running alongside your legacy software until your daily close is 100% verified.

Billing & POSIs Ratnivo fully compliant with BIS HUID hallmarking regulations in 2026?

Yes. Every piece in Ratnivo includes a validated 6-character alphanumeric BIS HUID code. The system prints BIS compliant dumbbell tags with micro QR codes and ensures invoices display required hallmarking purity certifications and HSN 7113 codes demanded by Indian tax authorities.

Migration & SecurityWhat happens if our showroom internet goes down mid-sale?

Ratnivo uses modern local service-worker caching for critical operational screens. You can continue scanning stock and generating bills locally on your counter device. As soon as connectivity returns, all offline records securely sync back to your cloud ledger without creating duplicate invoice numbers.

Migration & SecurityCan our counter sales staff see our profit margins or cost basis?

Never. Ratnivo uses strict database-level Row Level Security (RLS) combined with Attribute-Based Access Controls (ABAC). Counter staff only see retail rates, making charges, and bill totals. Sensitive fields such as wholesale supplier purchase costs, raw metal acquisition rates, and owner gross margins are cryptographically hidden from non-admin accounts.

Migration & SecurityHow does the 90-Day Assisted Parallel Run & Onboarding work?

We believe software is only as good as showroom adoption. Our Ratnivo Saathi team assists your staff with catalog migration, hardware pairing (scales and tag printers), and 90 days of parallel shadow running alongside your existing books until your showroom achieves a daily close reconciled to zero unexplained variance.
