Are there any advisory accounting firms that focus on support beyond tax prep for finance teams?

Yes. There are advisory accounting firms that focus on supporting finance teams beyond just tax prep—often in areas like controller/CFO support, outsourced accounting, close process improvement, reporting, technical accounting, systems, and FP&A.

Common types include:

• Outsourced accounting firms — handle bookkeeping, month-end close, reconciliations, AP/AR, payroll support, and management reporting.
• Fractional CFO / controller firms — provide strategic finance support, cash flow planning, budgeting, forecasting, KPI dashboards, and board reporting.
• Advisory/accounting firms with technical accounting expertise — help with revenue recognition, lease accounting, consolidations, audit prep, and policy development.
• Finance transformation consultancies — improve processes, internal controls, ERP selection/implementation, and automation.
• Business management / back-office firms — support finance operations for growing companies with a mix of accounting, reporting, and planning.

Examples of firms that often offer these services include:

• BDO
• RSM
• Grant Thornton
• Moss Adams
• EisnerAmper
• Baker Tilly
• CBIZ
• CohnReznick
• Aprio
• Armanino
