ProfitMultiplier

Reward your grinders. ProfitMultiplier gives every player a cumulative sell multiplier that climbs as they sell. The more a player sells, the more each future sale is worth. It hooks into your existing shop plugin and boosts the sale price at the moment of sale - there is nothing to migrate.

Sell 10K crops -> 1.1x, 100K -> 1.2x, 1M -> 1.3x. Every ladder is configurable.

What it does

• Cumulative progression - multipliers rise as a player crosses sold-total thresholds and stay unlocked forever. The boost is applied per unit, so a single sale that crosses a threshold only boosts the units at or after it.
• Three ladder types - per-item, shared groups, and a default fallback. See How It Works.
• Stacking control - decide per group whether the group multiplier replaces, defers to, or multiplies with a material's own multiplier. See Stacking Multipliers.
• Multi-shop support - EconomyShopGUI (+ Premium), ShopGUI+, zShop, UltimateShop, GUIShop, and EssentialsX /sell.
• Fully configurable GUI - custom items, PlaceholderAPI, click actions, pagination.
• Custom currencies - display formatting per group; multiplier works with any currency.
• Milestones - run console commands on tier-up, scale thresholds per donor rank, and announce achievements to Discord (embed or Components V2). See Milestones & Discord.
• Auto-updating configs - new default groups, messages, and menu files are merged into existing installs on update; your own values are never overwritten.
• Developer API - read progression, react to milestones, modify the boost.

Ships with eight ready-to-use groups out of the box: Crops, Ores, Resources, Excavation, Fishing, Nether, Mob Drops, and Building Blocks.
