We're launching 79Bullion, a hybrid precious metals platform on WordPress + WooCommerce:
Digital pooled metals (fractional buy/hold/sell gold/silver in grams/oz at near-spot, no storage fees, instant liquidity, partial sells, PDF certificates).
Physical bullion dropship via Elemetal (no inventory, price lock, $25 flat shipping).
Revenue from spreads, markups, dynamic fees ($8–$20), payment adjustments. Strict compliance: NOT securities/yield – clear disclaimers required.
This is a complex, advanced-scope project requiring custom plugin development (not just theme tweaks). MVP: 5 core pages + full backend (pricing engine, wallet/ledger, dashboards, integrations).
Key Requirements & Features to Build
Core Pricing Engine (critical – must be precise & performant):
Real-time spot price integration (scraper with fallbacks).
Dynamic calculations: spreads, volatility multipliers (5-min thresholds), weekend protection, payment adjustments (+1% default / +4.5% card), transaction fee tiers.
Per-product/SKU overrides (custom % markup or fixed $ premium for specific items like foreign coins/high-end brands; logged, flagged, admin-adjustable).
High-precision math handling.
Wallet/Ledger & Workflows:
Track fractional holdings, partial sells, 24h cooling period on buys.
Buy/sell/redemption flows (cash payout or physical ship).
Auto PDF certificate generation (with QR/unique ID, public verification page).
Integrations:
Elemetal automatic email for physical fulfillment.
Coinbase Commerce (crypto payments + webhooks).
Third-party KYC (Persona/Jumio) for credit card orders.
Daily supplier PDF import automation (parse/update Woo products/stock via Zapier/Make or custom).
QuickBooks Online sync (use MyWorks plugin or similar).
UI/Checkout & Dashboards:
Responsive/mobile-first (use Elementor pro if possible).
Product pages with calculator, payment selector, price lock timer (10 min).
Admin dashboard: Vault summary, overrides section, settings.
Customer dashboard: Holdings, certificates, history.
Security/Compliance:
Fraud checks, credit card cap ($5k hard limit), AVS/CVV, manual reviews.
Public transparency page (vault totals, coverage ratio).
