Hi, I’m Corey

I’ve spent 20+ years building finance processes and reporting systems. Now I help small businesses get dependable books and decision‑ready numbers without the hassle.

What I help with

Focused on QuickBooks Online and the recurring work that keeps your numbers right.

  • Monthly reconciliations
    Bank and card accounts tied out on a schedule.
  • Monthly close
    A clear checklist so nothing gets missed.
  • QuickBooks Online setup
    Clean file, custom chart of accounts, sensible defaults.
  • Cleanup projects
    Fix what needs attention and get back on track.
  • Excel reports
    Build or automate recurring reports to save hours.
  • Owner snapshots
    Short notes on what changed and why (no jargon).

Beyond bookkeeping

While most clients engage me for bookkeeping and QuickBooks support, my background also includes building reporting, analytics, automation, and capital infrastructure for rapidly growing companies.

Growth & Financial Infrastructure

  • KPI & reporting design
    Build executive dashboards and reporting frameworks that improve visibility and decision-making.
  • Financial modeling & forecasting
    Cash flow forecasting, budgeting, scenario planning, and business performance analysis.
  • Process improvement
    Identify bottlenecks, eliminate manual work, and create scalable workflows.

Data, Automation & AI

  • Excel, SQL & Power Query
    Connect systems, automate reporting, and reduce hours of manual work.
  • AI-enabled workflows
    Leverage AI tools to improve reporting, documentation, analysis, and operational efficiency.
  • Fractional finance leadership
    Support growing companies with finance, analytics, systems, and strategic planning expertise.

Prior experience includes helping scale platforms from startup environments to institutional organizations supporting billions of dollars in assets, financing, and annual originations.
