Match the role to the problem
A growing contractor can have plenty of work and still struggle to answer basic financial questions. Which jobs are actually making money? How much cash is available after next week’s obligations? Can the business afford another project manager? The right construction accounting services depend on which answers are missing.
A bookkeeper, controller, and fractional CFO serve different purposes. Bookkeeping records what happened. Controller-level work makes those records consistent, timely, and useful. Fractional CFO support uses reliable numbers to help the owner plan and make decisions. These functions overlap, but they are not interchangeable.
For contractors doing roughly $2 million to $15 million in annual revenue, the best setup is not necessarily three full-time hires. It may be an internal bookkeeper supported by an outsourced controller, with fractional CFO involvement for forecasting and major decisions. Start with the work your business needs, not the title that sounds most senior.
What a construction bookkeeper should handle
A construction bookkeeper maintains the transaction-level records behind your financial reports. That includes vendor bills, customer invoices, receipts, bank activity, and account reconciliations. In contracting, the work also requires consistent job and cost coding so project spending does not disappear into broad expense categories.
A strong bookkeeper can tell you whether a bill was entered, which customer invoices remain unpaid, and whether bank activity agrees with the accounting system. Depending on the agreed scope, the role may also maintain retainage balances, organize supporting documents, and record entries from your payroll provider.
Bookkeeping cannot fix information that never reaches the office. If supervisors submit receipts without job numbers or project managers delay billing details, even careful bookkeeping will fall behind. Owners need a simple process for getting complete information into the system on time.
- Typical responsibilities: transaction entry, accounts payable and receivable records, bank and credit card reconciliations, and consistent job coding.
- A good fit when: transactions are missing, reconciliations are overdue, invoices go out late, or job costs land in the wrong place.
- Ask before hiring: Who resolves coding questions, how are missing documents tracked, and when will reconciled reports be ready?
What a controller adds
A controller oversees the quality of the accounting process. Instead of simply making sure transactions are entered, the controller checks whether the financial statements make sense, whether balance sheet accounts have support, and whether the monthly close follows a repeatable schedule.
For a contractor, that often means reviewing job cost reports, receivables, payables, retainage, and work-in-progress reporting where appropriate. A useful WIP process connects contract values, approved changes, costs to date, and current estimates of remaining costs. The controller coordinates the accounting, but project managers must provide credible estimates to finish.
Controller-level support also builds controls that protect the business. Examples include separating vendor setup from payment approval, defining purchasing authority, and requiring review of unusual entries. Smaller teams may not be able to separate every duty, so owner review becomes important.
If your books are technically current but profit swings without a clear explanation, you may have a controller-level gap. The same is true when reports change repeatedly after month-end or the owner has to investigate every balance. Confirm accounting treatments that affect tax reporting with your CPA.
- Typical responsibilities: monthly close oversight, account reviews, reporting standards, WIP coordination, and accounting controls.
- A good fit when: reports are inconsistent, job results do not reconcile with company results, or accounting depends on one person’s memory.
- Ask before hiring: What gets reviewed each month, who owns the close checklist, and how will unresolved issues be reported?
What a fractional CFO should help you decide
A fractional CFO provides part-time financial leadership. The role should connect accounting results to operating decisions: how much work to take on, when to hire, what equipment the business can support, and how payment timing affects cash. It is more than presenting a profit-and-loss statement during a monthly call.
For example, a contractor may show a profit while cash tightens because receivables are growing, retainage remains outstanding, and material deposits are due before customer collections. A fractional CFO helps model those timing differences and compare options before the owner commits to more work.
Useful tools include a rolling cash forecast, an operating budget, backlog analysis, and scenarios for changes in margin, staffing, or collection timing. The assumptions should be visible. A forecast that assumes every customer pays on time is not much help if actual collections are routinely delayed.
A fractional CFO may also help organize financial information for lender discussions, but cannot guarantee financing. Tax strategy belongs with your CPA, and legal questions about contracts, collections, or business structure belong with your attorney. CFO advice should work alongside those professionals, not replace them.
- Typical responsibilities: cash forecasting, budgets, scenario planning, financial decision support, and owner-level performance reviews.
- A good fit when: reliable reports exist, but growth, cash needs, or major commitments require forward-looking analysis.
- Ask before hiring: Which decisions will we work on, what forecasts will be maintained, and how will assumptions be updated?
Build the right combination of construction accounting services
Revenue alone should not determine your staffing. A contractor with a few long-running projects may need different support than a service business with hundreds of small jobs. Project complexity, billing requirements, office capacity, and the quality of existing records matter as much as company size.
Start by identifying the bottleneck. If transactions are weeks behind, strengthen bookkeeping first. If transactions are current but reports are unreliable, add controller oversight. If reports are dependable but decisions still rely on guesswork, fractional CFO support may be the next step. Urgent cash planning can happen during cleanup, but early forecasts should clearly identify gaps and uncertainty.
When comparing providers, ask for a written scope rather than a list of titles. Clarify who enters transactions, approves payments, prepares billing, updates project estimates, reviews the books, and leads financial meetings. Also define which tasks stay with your team or outside providers, including payroll processing.
Expect the proposal to distinguish cleanup from ongoing service. Bringing old reconciliations current is a different assignment from maintaining a monthly close. Agree on deliverables, deadlines, access to systems, and how additional work is approved. A clear division of responsibility is more useful than a broad promise to handle everything.
When to get help
Consider outside help when you cannot confidently explain cash availability, job profitability, or the numbers on your balance sheet. Other signs include recurring close delays, surprise vendor obligations, and growth decisions made without a forecast. You do not need to wait for a cash crisis to clarify responsibilities.
Contractor Plus Books provides accounting and fractional CFO support for established contractors. It is not a CPA firm, does not process payroll, and does not guarantee financing. Tax and legal questions should be confirmed with your CPA or attorney.
A 20-minute financial review can help you see where your numbers stand and whether the immediate need is bookkeeping, controller oversight, or forward-looking financial support. The goal is to identify a practical next step, including when improving your existing process may be enough.
