Dynamic Supply/Demand Pricing

QBCore shop economy where per-item prices float server-side with stock scarcity and recent sales velocity for a living market.

Description

A dynamic-pricing engine where every shop item's price is computed server-side from a scarcity factor (current stock) and a velocity factor (recent sales), clamped to a sane band, so a hot item climbs and a glutted one falls. Servers buy it because a market that visibly breathes is a defensible economy-sim feature that is hard to clone and keeps an in-game economy feeling alive.

Known Failure Modes & Corrective Prompt

  • Client-side price — a price computed in NUI lets a client buy cheap. Evaluate priceOf server-side at purchase.
  • Client-trusted total — recompute price*qty on the server before charging.
  • Single-source update — broadcast dyn:priceUpdate to -1, not source, so all shoppers see the new price.

Corrective re-prompt: Move priceOf and the shops state entirely server-side, recompute the total inside the dyn:buy handler from the live item state, and change every price-update broadcast to -1 so the market stays consistent across all shoppers.

Framework Integration

ESX: swap to xPlayer.getMoney/removeMoney and xPlayer.addInventoryItem; keep the shops table and the price curve server-side unchanged. QBCore: native — Player.Functions.RemoveMoney('cash', n) and AddItem; resolve with GetPlayer(src). QBox: identical to QBCore via exports.qbx_core:GetPlayer(src); pairs well with ox_inventory item registration.

Profit Potential

$300–$3500/mo on Tebex (expected ~$1000). [INFERRED] priced inside the $50-389 standalone-script band against the signal-scraper corpus (tebex_snapshot n=100, median seller $11.85K/mo) for a rising economy-sim niche.

Trend Signal

↗ rising — strategy: Matrix favors defensible economy-sim mechanics; dynamic pricing is hard to clone, high Compound.

Sales Angle

Position as a defensible economy primitive: prices that breathe with scarcity and demand, the kind of living-market feature buyers can't get from a static shop. Recommended Tebex price: $349.
