What system does Five Guys use for managing store financials?

The correct choice highlights that Five Guys uses a "Back of house" system for managing store financials. This system typically includes all operational areas that are not customer-facing, such as inventory management, financial reporting, and employee management. In the context of Five Guys, the back-of-house systems help ensure that the restaurant operates smoothly by tracking expenses, payroll, and inventory levels, which ultimately contribute to the financial health of each store.

Using a back-of-house system allows for efficient and accurate financial management, which is crucial in maintaining profitability and making informed business decisions. It provides managers with critical insights into cost control and revenue generation, enhancing overall operational effectiveness.

The other options, while related to restaurant operations, do not specifically address the financial management aspect. The front-of-house refers to customer service areas where patrons interact with staff, the café manager typically implies a specific role within a café setting rather than a financial system, and the store performance system would generally encompass broader metrics rather than focusing specifically on financial management.
