💲Billing Services

Cross-platform in-app purchase system for Unity mobile games with consumables, non-consumables, subscriptions, and transaction management

Essential Kit's Billing Services feature lets Unity teams monetize mobile games with in-app purchases without maintaining platform-specific code. This tutorial walks you through setup, key APIs, testing, and troubleshooting so you can add consumables, non-consumables, and subscriptions with confidence.

Key Use Cases

Sell Virtual Goods

Use consumable products to sell in-game items like coins, gems, lives, or power-ups that players can purchase repeatedly. Offer multiple value tiers ($0.99, $4.99, $9.99) to maximize revenue across different player segments.

Premium Upgrades

Sell permanent features with non-consumable products like ad removal, character unlocks, or premium level packs. Once purchased, these items are owned forever and automatically restored across devices.

Subscriptions

Implement VIP memberships, battle passes, or season passes with recurring billing. Offer flexible durations (weekly, monthly, yearly) with introductory offers and free trials to increase conversion.

Multi-Currency Systems

Support multiple virtual currencies (coins, gems, tickets) using payout definitions. A single purchase can grant multiple currency types for complex economy systems.

Remove Ads

Offer an ad-free experience with a non-consumable product. Use IsProductPurchased() to check ownership status and hide ads permanently for paying users.

Prerequisites
