Lot 01 / Why teams switch
Stones go out on memo, sit in consignment, get listed on marketplaces and entered in tenders — while their status lives in spreadsheets, chat threads and portals that don't talk to each other. Every gap between those tools is stale stock data, a missed follow-up, or financial exposure you can't see.
Location, paperwork, pricing, client interest and every sale it has been through — all of it stored against the stone and kept as a full history. Nothing is overwritten, so you can always see what changed, when, and who changed it.
Lot 02 / The platform
Four capabilities, deeply connected. Enough to see what BidGemmer replaces — the full walkthrough happens on your demo, with your workflows.
Track every stone and parcel from rough to sold — through memo, consignment, marketplaces and tenders — with its full history, documents and certificates attached.
Inventory · Sharing · ProvenanceClient preferences, viewing history, offers and follow-ups in one timeline — so the right stone reaches the right buyer before the moment passes.
Clients · Offers · Follow-upsInvoicing, valuations, costs and yield flow straight from operations. Know your exposure on memo and your margin per stone — without month-end archaeology.
Invoicing · Valuation · Memo · ExpensesRun tenders and auctions from the same system that holds your stock — lots, bidders, results and invoicing in one flow. Not an add-on. Not an integration.
See the full sale lifecycle →Cloud-based, works anywhere, and syncs listings with marketplaces like Nivoda and RapNet — so stock stays current on every channel.
A team that knows the trade imports your stock lists, maps your price books and stays with you through the switch.
Lot 03 / Auctions & tenders
BidGemmer started as auction and tender software for the stone trade — the ERP grew around it. Most systems treat your sale as an export at the end; here the entire lifecycle runs on the same records as your stock, from catalogue to settlement.
Build lot catalogues straight from live inventory — photos, certificates, reserves and estimates attached, no re-typing.
Invite, vet and onboard bidders with the access and terms you set — per sale, per lot category, per client.
Schedule viewing sessions, track who inspected which lot, and log interest and remarks — intelligence that feeds the sale.
Viewing management moduleRun tenders or auctions with live bid status, closing rules you control, and a full audit trail of every bid.
Winners notified, invoices raised, settlement tracked — and prices-realized analytics ready for your next sale.
Lot 04 / AI pricing & trends
Not AI for its own sake — artificial intelligence applied to the two jobs that decide whether a stone sells well: grading it consistently, and pricing it correctly.
Because results stay attached to the stones and buyers behind them, your own history becomes the reference.
Lot 05 / Security
Your stock list, your prices and your client book are the business. BidGemmer is engineered so that they stay yours — protected, isolated, and visible only to the people you choose.
Strict tenant isolation by design: your inventory, pricing and clients are never visible to any other company on the platform, never sold, and never used to train anything.
Role-based permissions at field level — a sorter sees weights without costs; a broker sees only their consignment. A full audit log records who viewed, changed or exported what, and when.
Hosted on AWS infrastructure, with encryption in transit and at rest, secure sign-in with SSO and two-factor authentication, and an architecture aligned with recognized security standards.
