Single-Entry Accounting
What is Single-Entry Accounting?
Single-entry accounting is a simplified bookkeeping method where each financial transaction is recorded only once, typically as either income or an expense. Unlike double-entry accounting, which requires balancing debits and credits across multiple accounts (asset, liability, equity, etc.), single-entry accounting functions more like a detailed checkbook register.
It’s a simple system that works well for smaller contractors with straightforward billing. But as your projects, clients, and payment terms get more complex, it can become limiting, often requiring extra spreadsheets and manual workarounds.
That’s where Siteline comes in. Built specifically for commercial subcontractors, it automates progress billing, manages custom GC requirements, and provides accurate, real-time cash tracking and reporting, helping you keep projects moving and payments on schedule. Learn more about Siteline.

What is a General Ledger (G/L)?
A General Ledger (G/L) in the construction industry is a fundamental financial tool for recording all financial transactions of a construction company including assets, liabilities, equity, revenue, and expenses. It not only reflects every financial transaction related to a construction project, but also contains crucial details such as date, description, and transaction amount. Essentially, the G/L acts as the core of a construction company's financial record system where all transaction data from sub-ledgers or modules, such as accounts payable, accounts receivable, and cash management, are consolidated. It provides a comprehensive financial picture necessary for reporting and strategic decision-making in the construction business. By regularly maintaining and auditing the G/L, construction companies can ensure financial accuracy and compliance, as well as evaluate their financial performance and stability.
What is an unconditional lien waiver?
An unconditional lien waiver in the construction industry is a signed document from a contractor, subcontractor, materials supplier, laborer, or other party involved in a construction project, which gives up their right to place a lien on the property unconditionally, typically after they have received full or partial payment for their work or materials. It serves as a guarantee to the property owner that they will not face a lien, or legal claim against their property, for this party's unpaid work or supplies, regardless of whether the party is subsequently paid in full or not.
Unconditional waivers come in two forms, tied to when you're billing:
- Unconditional progress waiver: Submitted after you've been paid for a progress billing period. It waives your lien rights for the work covered by that payment.
- Unconditional final waiver: Submitted after you've received full and final payment, including retainage. It waives all your lien rights for the entire project.
Unlike a conditional waiver, an unconditional waiver takes effect the moment you sign it—whether or not the money has actually arrived. That makes timing critical: never sign one until the payment has cleared your account, or you'll have given up your lien rights with no guarantee of getting paid.
What is Cash Flow?
Cash flow, as applied to the construction industry, refers to the net amount of money moving in and out of a construction business within a defined period of time. This includes income from clients, loan repayments, supplier payments, salaries, and overhead costs. Crucially, understanding cash flow is vital for a construction firm as it helps in making strategic decisions for sustainable growth. It can be used to assess the liquidity and overall financial health of a business. With an active construction project, cash flow can be unpredictable due to unexpected expenses, delayed payments, or cost overruns, requiring diligent cash flow management.
