Live spot, instant karat math, on-screen signature pad, PDF receipts — host a gold party with the same toolkit professional buyers use at the counter.
Always free to use. Every new account unlocks all Pro features for 2 weeks — no credit card required.
PDF receipts with a seller signature (your business logo on Stacker and up). Sellers see a real number instead of a paper-bag estimate.
Voice input plus the multi-piece form means you can clear a tray of jewelry while keeping conversation going.
Sellers ask 'how do you get to that number?' — show them. Live spot × purity × weight × payout %, all on screen.
Every host and guest stays in your CRM. Six-month follow-ups become a single tap, not a stack of notebooks.
After the party, open a Google Maps search for nearby gold buyers and refiners and turn the haul into cash the same week.
Calculator math runs locally; live spot needs network access for the 60-second refresh. Bring a hotspot for parties in spotty venues.
Nu Stack records every buy with date, seller, weight, purity, and amount paid. Whether your tax setup is hobby income or a Schedule C is between you and your accountant.
No. Nu Stack is a calculator and ledger. There are no transaction fees and no payment processing inside the app.
No credit card. Always free to use. Every Pro feature unlocked for the first 14 days.
2 weeks of Pro free — no credit card required
