M3

M3 is a hospitality financial management system built specifically for hotel owners, operators, and management companies. It combines hotel accounting, labor management, business intelligence, outsourced accounting services, and integrations that connect financial data with property, point-of-sale, payroll, banking, and other hotel systems.

1. Hotel accounting: Accounting Core is M3’s enterprise accounting product, with multi-property general ledgers, intercompany transactions, accounts payable, automated journal entries and reconciliations, payments, budgeting, financial reporting, and PMS data processing. CoreSelect is the streamlined alternative for independent and growing portfolios of roughly 2–30 properties, adding automated daily revenue imports, invoice processing, bank reconciliation, payments, and portfolio reporting.
2. Business intelligence: Insight combines data from Accounting Core, Labor Management, PMS, guest-satisfaction, STR, and on-the-books sources into customizable dashboards. Hotels can track revenue, expenses, occupancy, NOI, labor costs, budget variance, and property or portfolio performance, while built-in budgeting, forecasting, and formula-building tools support forward planning and custom hospitality KPIs.
3. Labor and connected data: Labor Management tracks hours, wages, staffing, productivity, and schedules against forecast demand and budgets, with labor information flowing into Accounting Core and payroll systems. Accounting Core currently advertises integrations with 70+ PMS, POS, and payroll providers, while M3’s wider integration ecosystem includes systems such as Oracle OPERA, Mews, Cloudbeds, ADP, Paychex, Paylocity, and financial/payment partners.
4. Commercial structure: M3 is modular rather than sold as one mandatory bundle. Buyers can select Accounting Core or CoreSelect and add Labor Management, Insight, and hospitality accounting services as needed. M3 does not publish a standard rate card for its main software portfolio; sales are primarily demo- and quote-led, while outsourced accounting can range from targeted assistance to ongoing or full-cycle accounting engagements.

M3 is most relevant to hotel owners and management companies that want hospitality-specific accounting and portfolio reporting connected directly to hotel operational data rather than adapting a general-purpose accounting package.
