Myer Jewelry ERP System


Designing a tailored ERP System Solution for Myer Jewelry (美亞珠寶)—a prominent Hong Kong fine jewelry manufacturer, exporter, wholesaler, and retailer established in 1978—requires addressing the dual demands of precision manufacturing (OEM/ODM export) and omni-channel retail/wholesale operations.

Myer Jewelry specializes in fine diamond, gemstone, and precious metal jewelry, exporting globally while serving local retail and wholesale clients. Below is the end-to-end ERP solution blueprint specifically engineered for Myer Jewelry's business model.

1. Key Industry & Company Pain Points Addressed

  • High-Value Raw Material Management: Precise tracking of individual diamonds (GIA/certificated and non-certified parcels), colored gemstones, and precious metals (Gold/Platinum) by purity and weight (carats/grams).

  • OEM/ODM Manufacturing & Custom Orders: Complex Bill of Materials (BOM) management for mass production and bespoke custom designs—tracking casting, setting, polishing, and plating stages.

  • Precious Metal Loss & Loss Control: Accounting for physical metal loss during manufacturing (casting loss, filing dust recovery) vs. standard allowable tolerances.

  • Global Wholesale & Consignment Tracking: Multi-currency international invoicing (USD/HKD/EUR/RMB), cross-border logistics, consignment stock at overseas trade counters, and exhibition inventory management (e.g., HKTDC International Jewellery Show).

Module-by-Module ERP Solution Blueprint

Module 1: Diamond, Gemstone & Precious Metal Vault Management

  • Parcel & Single Stone Tracking:

    • Certificated Diamonds: Track individual stones by GIA/IGI certificate numbers, carat, color, clarity, cut, shape, and vault location.

    • Parcel Gemstones / Melee Diamonds: Track bulk lots by weight (carats/grams), average cost per carat, and automatically adjust inventory upon issue to factory work orders.

  • UHF RFID Bulk Inventory Audit:

    • Implement RFID tags on jewelry trays and individual tags. Warehouse and vault managers can scan entire trays containing 100+ items in under 3 seconds using handheld RFID scanners, reducing stocktake time by 90%.

  • Exhibition & Consignment Management:

    • Dedicated module for managing high-value stock dispatched to trade shows (HKTDC, Vicenzaoro, JCK Las Vegas) or consignment partners with real-time checkout and return auditing.

Module 2: Jewelry Manufacturing Execution System (MES / MRP)

  • Dynamic Jewelry Bill of Materials (BOM):

    $$\text{Standard Unit Cost} = \left(\text{Net Gold Weight} \times (1 + \text{Loss Factor \%}) \times \text{Spot Gold Price}\right) + \sum \text{Stone Costs} + \text{Crafting Labor}$$
  • Manufacturing Work-in-Progress (WIP) Tracking:

    • Job-card tracking through factory stages: 3D CAD/Waxing $\rightarrow$ Casting $\rightarrow$ Filing $\rightarrow$ Stone Setting $\rightarrow$ Polishing/Plating $\rightarrow$ Final QA.

  • Metal Scrap & Dust Recovery Accounting:

    • Monitor daily metal issuing vs. returned scrap/polishing dust per artisan to ensure zero shrinkage and enforce strict yield controls.

Module 3: Global Wholesale Export & Omni-Channel Retail

  • Multi-Currency Quotations & Orders:

    • Instant generation of wholesale quotations based on live daily precious metal spot prices (Gold/Platinum) and exchange rates (USD, HKD, RMB, EUR).

  • Trade Show Mobile Order Entry:

    • Mobile tablet application for sales representatives at international jewelry fairs to quickly scan barcodes/RFID, display 3D product catalog, generate instant customer quotes, and check real-time factory lead times.

  • E-Commerce & POS Integration:

    • Direct API synchronization with Myer Jewelry’s online store and retail counters for unified inventory control.

Module 4: Financial Management, Compliance & HK HR

  • Multi-Currency Accounting & Hedging:

    • Automated financial consolidation for HK headquarters and overseas sales offices. Features real-time inventory revaluation based on metal market fluctuations.

  • Hong Kong HR & Payroll:

    • Integrated attendance, multi-tiered sales commission calculations (retail and wholesale export teams), and Hong Kong MPF regulatory compliance.
