From Bookkeeper to CFO: Scaling Your Construction Company’s Financial Team

Gannon Thiel • July 28, 2025

As your construction business grows, so do the financial demands that come with managing multiple jobs, complex billing structures, fluctuating cash flow, and bonding requirements. What started as a manageable task for a part-time bookkeeper can quickly evolve into a critical need for strategic financial leadership. Knowing when and how to scale your financial team can make the difference between reactive bookkeeping and proactive growth.

The Early Stage: Bookkeeping Basics

In the early stages of a construction company, a bookkeeper typically handles:

  • Recording transactions
  • Reconciling bank accounts
  • Managing accounts payable and receivable
  • Supporting payroll and invoicing


While essential, this role is task-oriented and focused on historical data, ie. "what happened." For small contractors, this is often enough. But as project size, headcount, and revenue increase, gaps begin to show.

The Growing Pains: When Bookkeeping Alone Isn't Enough
Here are some common signs your business has outgrown a basic bookkeeping setup:

  • Job costing is unclear or inaccurate
  • Cash flow feels unpredictable
  • You’re unsure about what’s profitable (and what’s not)
  • Your bonding agent is asking for financials you can’t produce
  • You have no forecast or budget guiding decisions


These symptoms indicate a need for higher-level financial insight and infrastructure.



The Next Step: Adding Controller Oversight

A controller brings oversight and consistency to your financial operations. This role is focused on accuracy, compliance, and timely reporting.


Key responsibilities include:

  • Producing monthly financial statements
  • Ensuring job costing and WIP reports are accurate
  • Establishing internal controls
  • Managing accounting systems and policies


A controller helps your business get reliable, timely data, which is a must-have for bonding, banking, and operational decisions.



Strategic Leadership: Bringing in a CFO

Once your company reaches a certain size or complexity, a CFO can provide the strategic lens your business needs. Unlike a bookkeeper or controller, a CFO is forward-looking and decision-oriented. Their focus is on financial strategy, growth planning, and risk management.


Key contributions of a CFO include:

  • Developing forecasts and cash flow models
  • Guiding capital decisions (equipment, financing, growth)
  • Supporting bonding conversations with data-driven insight
  • Evaluating profitability across projects and divisions


A fractional CFO model, like the one Groundwork Financial offers, can deliver these benefits without the cost of a full-time executive.

In construction, every job tells a financial story. But without accurate job costing, contractors are essentially flying blind. Relying on intuition instead of insight to guide their decisions. At Groundwork Financial, we believe job costing is more than an accounting function...it’s a strategic tool that can unlock profitability and fuel smart growth.

When a big job comes up and bonding is on the line, contractors don’t have the luxury of time. Yet, many construction businesses find themselves scrambling to produce accurate financials that meet surety standards.
