Zero-Balance Account

What is a Zero-Balance Account?

A zero-balance account (ZBA) is a financial tool commonly used in construction accounting where the account balance is maintained at or near zero. Funds are transferred to the ZBA as needed to cover expenses or payments, typically from a parent account. Once a transaction has been made from the ZBA, that amount spent is automatically transferred from the parent account, so the ZBA balance returns to zero.

In the complex world of construction projects—where multiple subcontractors are involved—ZBAs allow the general contractor (GC) to closely monitor and manage cash flow for each subcontractor on the project. This system prevents excess funds from sitting idle in numerous accounts—and potentially forgotten as the project progresses. It also provides a clear audit trail for each subcontractor’s expenses, making it easier to track costs against budgets to identify any discrepancies or unusual spending patterns. Additionally, ZBAs can help reduce the risk of fraud or unauthorized spending, as funds are only transferred on an as-needed basis.

ZBAs provide a level of control and visibility that is crucial for maintaining liquidity and profitability—much like Siteline. Siteline allows subcontractors to easily track their inflows and outflows, providing a clear financial picture of each project and the company overall. Interested in learning more?

Joint Check Agreement

What is a Joint Check Agreement?

A Joint Check Agreement is a contractual agreement in the construction industry used to ensure all parties involved in a project get paid. This agreement involves primarily three parties - the property owner, general contractor, and subcontractor or material supplier. The property owner or general contractor issues a check payable to both the subcontractor and materials supplier, providing a layer of protection against mechanic's lien. This means both parties must endorse the check for it to be cashed, ensuring the funds are distributed appropriately. This way, it mitigates the risk of non-payment for subcontractors and suppliers. Additionally, it helps the owner or general contractor to ensure project progression without disputes or delays related to payment issues. However, details of the agreement, like the proportion of payment to each party, need to be clearly outlined to avoid potential conflicts.

Billings in Excess of Costs

What is Billings in Excess of Costs?

Billings in excess of costs (also called overbillings) occur when you’ve invoiced your client for more work than you’ve actually completed or incurred costs for. In other words, it represents getting paid ahead of your work schedule.

Here’s how it works: If you’re a concrete subcontractor on a $100,000 job and you bill 50% upfront ($50,000) but have only completed $30,000 worth of work, that $20,000 difference is your billings in excess of costs. You owe your client that work, and until you complete it, that $20,000 remains as a liability on your balance sheet.

For subcontractors, understanding billing in excess of costs is essential because it can be a strategic cash flow tool when used carefully. For example, when bidding on a job, you can be smart about how you structure your schedule of values (SOV)—breaking work down into more detailed line items that allow earlier billing. However, this strategy requires regular monitoring to ensure:

  • Your billing somewhat aligns with your actual percentage complete, and 
  • The remaining contract value will still cover your remaining costs.

The biggest risk of overbilling is thinking your margins look better than they are, simply because you’re collecting cash faster. Surety companies and lenders also scrutinize overbillings closely, as excessive amounts can signal poor project management or potential cash flow problems down the road.

With Siteline, you can easily track whether you’re billing in excess of your costs by pulling your month-to-month incurred costs and comparing them against your billing progress. This real-time visibility helps ensure you’re billing appropriately while maintaining realistic profitability expectations.

Quantity Survey

What is a Quantity Survey?

A quantity survey, also known as a bill of quantities (BOQ), in the construction industry is a detailed analysis and estimation of all parts, materials, and costs associated with a construction project. This process is carried out by a professional known as a quantity surveyor. The surveyor evaluates the quantities of materials needed, required labor, groundwork needed, and the overall time frame of the project. They also consider other variables to provide an accurate cost analysis, like the complexity of the project, the potential risks, and the market conditions.

The main purpose of a quantity survey is to:

  • Accurately estimate the cost of a construction project: By quantifying all the required materials and resources, the quantity survey helps contractors and clients estimate the total cost of the project accurately. For subcontractors specifically, quantity surveys are used to price out the cost of their portion of the work, ensuring they quote competitively while accounting for all the necessary materials and labor.
  • Facilitate bidding and tendering: The quantity survey provides a standardized format for subcontractors to prepare their bids based on the same information, ensuring fair competition during the tendering process.
  • Control project costs: During the construction phase, the quantity survey serves as a reference point for monitoring and controlling costs, as actual quantities used can (and should) be compared against estimated quantities.
  • Manage changes: If the original scope of work changes or varies, the quantity survey serves as a baseline for evaluating and negotiating the cost implications of those changes.

A quantity survey is essential for subcontractors to accurately estimate costs, plan resources, and manage project scope. While not directly integrated, solutions like Siteline allow subcontractors to leverage quantity survey data to streamline their billing processes.

  • Subcontractors can generate payment applications in Siteline that reflect completed work items and quantities from the survey, minimizing disputes.
  • Some clients use Siteline's billing and A/R reports to help quantity surveyors and estimators account for contractors with longer payment cycles. They can either increase bids for those contractors to offset delays or revise terms to penalize late payments.
  • Siteline also seamlessly tracks change orders, enabling subcontractors to easily update payment applications and lien waivers when project scope changes, keeping everything documented and billed accurately.

By bridging the gap between contracted scope and actual billing, Siteline enables subcontractors to focus on execution while ensuring prompt, accurate payments. Experience the power of efficient payment management tailored for subcontractors. Schedule a demo of Siteline today.
