Frequently Asked Questions
What restaurant finance functions can GSS manage for my brand?
GSS covers the full back-office stack for restaurants—outsourced bookkeeping and financial statements, managed payroll, and CFO-level analytics—delivered as modular Accounting, Payroll, and CFO service lines.
How does outsourcing to GSS lower my overhead yet lift accuracy?
A near-shore delivery model and deep restaurant automation let GSS provide "above-market service, below-market prices," giving you cleaner books and real-time insight without the payroll burden of an in-house team or the premiums of a large CPA firm.
Is Global Shared Services (GSS) a restaurant payroll software provider?
No, Global Shared Services (GSS) is not a software platform. Instead, it is an outsourced accounting and restaurant payroll services firm that leverages and integrates with leading restaurant payroll software and technologies like Restaurant365, QuickBooks accounting software, ADP, and various POS systems to deliver comprehensive payroll and accounting solutions tailored for the restaurant industry.
Can you integrate with Restaurant365 and the systems I already use?
Absolutely. GSS is a Restaurant365 partner and routinely syncs with QuickBooks, ADP, Sage, Bill.com, and leading POS platforms, so your operational data flows straight into unified financial dashboards.
How fast can you get us live?
Because the team focuses exclusively on restaurants, clients typically move from kickoff to first clean close in just a few reporting cycles. GSS's domain expertise drives markedly faster onboarding than generalist firms.
Where is the team located, and will time zones or language be an issue?
Delivery is anchored in Buenos Aires (Argentina time aligns with U.S. business hours), supported by U.S. leadership and a bilingual staff that speaks multiple languages, ensuring real-time, clear communication.
How do you keep my payroll and financial data secure?
GSS takes data protection very seriously, following strict international standards and walking each client through its security protocols during onboarding, so you know exactly how your information stays safe and compliant.
