RETHINKING YOUR CPA? MOST SUBS KEEP THEM AND ADD A LAYER.
A traditional CPA is built to look backward: tax returns, compliance and year end. That work still has to be done, and for most subcontractors the answer is to keep the CPA and add the work the CPA does not do, which is the monthly close, job costing and forward decisions. The alternatives are a construction-focused CPA firm, an outsourced CFO alongside your CPA, or an in-house hire.
The mismatch is about time. A CPA firm works on the past, usually after the year ends, and construction finance happens inside the month: whether a job is making money, what over billing is doing to cash, what next quarter looks like. A construction subcontractor who relies on a CPA alone typically gets accurate tax returns and no answer to which jobs earn. That is not a failing of CPAs. It is a different job. The question is which parts of your finance function a CPA firm should keep, and which belong to someone who is in your numbers every month.
WHAT EACH ONE DOES.
| Capability | Keep the traditional CPA | A construction-focused CPA firm | An outsourced CFO alongside your CPA |
|---|---|---|---|
| Time direction | Backward, the year just ended | Backward, with more construction depth | Present and forward, monthly |
| Files tax returns | Yes | Yes | No, works with your CPA |
| Reviewed or audited statements for bonding | Yes | Yes, with construction depth | No |
| Owns the monthly close | Usually not | Usually not | Yes |
| Designs job cost structure against the estimate | No | Rarely | Yes |
| Forecast and what-if decisions | No | Sometimes as advisory | Yes, a 13 week forecast |
| Catches a losing job mid job | No | Rarely | Yes |
| What happens without it | Penalties and missed elections | Weaker bonding position | Accurate returns, guessed decisions |
WHEN THE PROBLEM IS TAXES AND COMPLIANCE.
If your books are current, your jobs are costed and you know where the money goes, a CPA for taxes and compliance is the right call. They know the filings, the elections and the entity questions. Paying a CFO to do what a CPA does well is wasted money.
It stops working when you expect the CPA to run the numbers. They see a year in one pass and they are not in your close, so nobody is looking at a job while it can still be fixed.
WHEN YOU WANT THE CPA TO KNOW CONSTRUCTION.
A CPA firm that specializes in construction understands WIP, percentage of completion revenue recognition, retention and bonding and surety reporting. If your bonding company wants a reviewed or audited statement, that is CPA territory, and a specialist does it better.
It is still mostly a backward-looking service with a heavier emphasis on the year. Many such firms offer advisory work too, so ask what the monthly relationship looks like and who does it.
WHEN YOU NEED THE MONTHLY NUMBERS RUN.
An outsourced CFO handles the monthly close, job costing against the estimate, the forecast and the decisions that come out of them, and gives the CPA a clean record at year end. The two roles do different jobs and work well together, and a clean record usually makes the CPA cheaper to use.
The limit is that a CFO is a different job from tax filing and does not replace the CPA for filings or attestation work. Anyone who tells you otherwise is selling something. SPM keeps your CPA in the loop and does not file returns.
WHERE WE COME OUT.
Keep a CPA. Taxes and compliance are not optional, and an outsourced CFO is not a substitute for filings or attestation work.
Switch to a construction-focused CPA firm if the thing that hurts is bonding, reviewed statements or percentage of completion revenue recognition. A specialist is better at those.
Add an outsourced CFO if you cannot answer which jobs earn money or when you will run short, because that is a monthly question and a CPA is not set up to answer it monthly. For most subcontractors, the answer is the CPA for the year and a CFO for the months.
