Arcade operators maintain complex inventory systems to ensure timely machine repairs and minimize revenue loss from downtime. Most establish a multi-tiered inventory strategy, keeping critical components like fuses, buttons, joysticks, and common IC chips on-site while partnering with specialized distributors for rare parts. Many utilize inventory management software to track part usage rates, set automatic reorder points, and maintain historical repair data.

Successful operators often standardize components across machines where possible, reducing the variety of spare parts needed. They cultivate relationships with multiple suppliers, including original manufacturers, third-party parts specialists, and even salvage operations for discontinued components. Preventive maintenance schedules help identify needed parts before failures occur, allowing for planned rather than emergency ordering.

Many operators also participate in industry networks and forums to source hard-to-find parts and share inventory resources with other arcades during critical shortages. The most efficient operations implement barcode systems for quick parts identification and maintain detailed repair logs that inform future inventory purchasing decisions, creating a continuously improving system that balances availability against storage costs.
