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.

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.

Time-and-material billing is a method used in the construction industry where a client is charged based on the actual cost of labor and materials for a project, along with an added markup for the contractor's profit. This approach promotes transparency as customers directly pay for the time spent on the project and materials used. The advantage of this method is the flexibility it provides - if a project scope is unclear or likely to change, it can be more efficient than a fixed-price model. However, it also contains a risk for the client, with a chance that costs could increase if the construction takes longer or requires more resources than estimated. It requires meticulous tracking of working hours, materials, and equipment used. The client also needs to keep an eye on the project to avoid unnecessary costs.
