5 Reasons to Hire a Bookkeeper NOW

Selecting an accounting method is one of the most critical structural decisions a construction business will make. While cash accounting offers simplicity and direct visibility into liquidity, accrual accounting provides a far more accurate reflection of long-term operational health by matching revenues directly with the expenses incurred to earn them. Given the prevalence of progress billings, subcontractor payables, and inventory costs in construction, transitioning from cash to accrual (or managing a hybrid model) often becomes mandatory as revenue grows. This guide breaks down the key mechanics of cash vs. accrual accounting for contractors, IRS eligibility rules, and how each method impacts your financial reporting and bottom line. Understanding Cash vs Accrual Accounting At its core, the difference between cash and accrual accounting comes down to timing : specifically, when your business officially recognizes income and expenses on its financial statements. ​Cash Basis Accounting: Driven by Money Flow Under cash basis accounting , financial transactions are recorded only when actual money changes hands: Revenue is recognized when a client's payment lands in your bank account. Expenses are recognized when cash leaves your account to pay a supplier, subcontractor, or bill. Example: You complete a framing job in October and send a $15,000 invoice. The client pays you in December. Under cash accounting, that $15,000 counts as December revenue—it does not exist on your income statement in October or November. For small trade contractors or solo operators, cash accounting is attractive because of its simplicity. It gives a direct, real-time picture of how much spendable cash is in your bank account today. Accrual Basis Accounting: Driven by Activity & Earnings Under accrual basis accounting , transactions are recorded when they are earned or incurred , regardless of when money actually moves. This method follows the matching principle , pairing project revenues with the exact expenses required to generate them.  Revenue is recognized as soon as you complete work or issue an invoice (Accounts Receivable). Expenses are recognized as soon as you receive a subcontractor bill or order materials (Accounts Payable). Example: Using the same framing job above, the $15,000 is recognized as October revenue because that is when the work was performed and billed, even though the cash won't arrive until December. While accrual accounting requires closer tracking of receivables and payables, it delivers a much clearer picture of your company's true profitability and operational health.

​There is a frustrating stage of growth when the business makes more money and becomes harder to run. You expected growth to create leverage. Instead, your calendar is fuller and decisions take longer. Projects compete for the same people. Expenses become harder to explain. Accounting needs more information from Operations. Operations needs more information from Accounting. And the accounting systems that carried you to $2 million were not built for $15 million. Nothing necessarily looks broken. That is what makes this stage so deceptive. The processes that got you here may still work. Your people may still be good. Your customers may still be buying. What changed is the weight your existing structure is being asked to carry. At $2 million, you can still personally compensate for the gaps. Somewhere on the road to $5 million, $10 million, or $15 million, that stops being possible. The business did not suddenly become dysfunctional. It outgrew its dependence on informal coordination.
