Software for diamond traders: stock aggregation, inventory and marketplace listing

    We build two things for diamond trading businesses: automation that turns mismatched supplier stock files into one priced, filtered list in under two minutes, and full inventory platforms that track every stone from purchase through pricing to sale. Both are running in live trading offices. The aggregation work cut a 2.5-hour daily Excel task to under 2 minutes; the inventory platform replaced Excel, WhatsApp and manual double-listing across RapNet and Nivoda with a single system.

    What this has produced

    • Stock aggregation cut from roughly 2.5 hours to under 2 minutes.
    • Ageing analytics surfaced 12 stones held 6+ months, representing roughly Rs 14 lakh in locked capital.
    • Average time-to-sell now tracked by cut: rounds around 14 days, fancy cuts around 67 days.
    • One upload updates both RapNet and Nivoda listings, ending manual double-listing.
    • Overdue part-payments flagged automatically instead of chased from memory.
    The Problems

    What we keep finding in diamond trading businesses

    Every supplier sends a different format

    Column names, ordering and units differ on every file. Merging them is manual work that has to happen before anything can be quoted, and it has to happen again every time stock changes.

    Margins and client filters are applied by hand

    After the merge, margins go on manually and the list gets cut down to each client's spec. By the time it reaches the client, the underlying stock has often moved.

    Ageing inventory is invisible

    Without intake dates attached to stones, slow-moving stock is only noticed when someone goes looking. Capital sits locked in it in the meantime.

    Listing on two marketplaces means doing everything twice

    RapNet and Nivoda want different formats. Keeping both current means reformatting the same file twice, every time anything changes.

    Part-payments are tracked from memory

    Payment schedules held in messages and heads mean overdue balances get found late, if at all.

    What We Build

    Systems we have shipped for this industry

    Supplier stock aggregation

    A mapping layer that resolves each supplier's format into one internal schema, applies margin rules on merge, and filters to each client's stored spec.

    Stone lifecycle inventory

    Every stone recorded once and carried through purchase, pricing and sale, so inventory and financials read from the same record.

    Public live stock lists

    Current available inventory published straight to the trader's own website, so buyers browse instead of asking for a file.

    Marketplace format conversion

    Upload a RapNet-format file and get the Nivoda-format file automatically. One upload keeps both listings current.

    Ageing and time-to-sell analytics

    Reports on what has been held longest, what that represents in locked capital, and average time-to-sell broken down by cut.

    Invoicing and expense management

    Invoice generation and management against the same stone records, plus salaries, utilities and business expenses tracked in the same system.

    Questions diamond trading buyers ask

    Can you handle our suppliers' Excel formats without us standardising them first?

    Yes — that is the point of the mapping layer. Each supplier's format is mapped once to the internal schema, after which their files merge automatically. You do not have to ask suppliers to change how they send stock.

    Do you support RapNet and Nivoda listing formats?

    Yes. We built a converter that takes a RapNet-format stock file and produces the Nivoda-format file automatically, so a single upload keeps both marketplace listings current with no manual reformatting.

    Can buyers see our stock without us sending files?

    Yes. We publish a live stock list on your own website, driven by the same inventory records, so buyers browse current availability themselves.

    How long does a diamond inventory system take to build?

    The aggregation automation on its own is a short engagement, usually a few weeks, because it targets one bottleneck. A full inventory, invoicing and expense platform is phased over several months so each module goes live as it lands.

    Do you work with traders outside India?

    Yes. We are based in Mumbai and work with trading businesses in the UAE, particularly Dubai and DMCC, and in the USA. Delivery is remote with overlap hours arranged around your timezone.
