## FAQ — Construction Bookkeeping Questions & Answers
URL: https://scaffoldbookkeeping.com/faq
297 questions organized by category. All answers sourced from US federal regulations and Washington State law.

### AIA Billing & Progress Payments
**Q: What are the primary functions of the AIA G702 and G703 forms in construction billing?**
A: The AIA G702 serves as the Application and Certificate for Payment, summarizing the contract sum, changes, and amount due, while the G703 serves as the Continuation Sheet, providing a detailed breakdown of each line item in the schedule of values.

**Q: What is the maximum retainage rate allowed on public works projects in Washington State?**
A: For public improvement contracts, public bodies must reserve a contract retainage not to exceed five percent of the moneys earned by the contractor. (Source: RCW 60.28.011)

**Q: Are electronic signatures legally binding on AIA payment applications in Washington?**
A: Yes, Washington law recognizes electronic records and signatures as having the same legal effect as physical signatures, provided they meet the standards for authenticity and intent under the Uniform Electronic Transactions Act.

**Q: When must a general contractor pay a subcontractor after receiving payment from the owner on a public project?**
A: General contractors must pay their subcontractors for satisfactory performance within ten days of receipt of each progress payment from the state or any county, city, or town. (Source: RCW 39.04.250)

**Q: Can Washington contractors charge interest on late progress payments?**
A: Yes, if payment is not made within thirty days of a proper pay request, the unpaid amount shall bear interest at the rate of one percent per month until paid. (Source: RCW 39.76.011)

### Job Costing & Profitability
**Q: What is job costing in construction?**
A: Job costing is an accounting method that tracks all costs—labor, materials, subcontractors, equipment, and overhead—to individual construction projects. It allows contractors to see the true profitability of each job rather than relying on estimates.

**Q: What are the main cost categories in construction job costing?**
A: Labor (field crew wages, prevailing wage, overtime, benefits), Materials (lumber, concrete, electrical supplies), Subcontractor costs, Equipment (rental, depreciation, fuel), and Overhead (insurance, office, permits, supervision).

### Tax Compliance & Filing
**Q: What is Washington State B&O tax for contractors?**
A: A business and occupation tax based on the gross income of a business, specifically required for contractors operating in Washington State.

**Q: How does sales tax apply to construction materials?**
A: In Washington State, contractors generally pay sales tax on materials at the time of purchase. The application varies depending on whether the project is a retail sale, speculative build, or government contract.

### Payroll & Labor Compliance
**Q: What is certified payroll?**
A: Detailed reports required on government-funded projects that prove workers are being paid the legally required prevailing wage. Required under the Davis-Bacon Act for federal projects.

**Q: How do you classify workers as employees vs. independent contractors?**
A: Classification depends on behavioral control, financial control, and the type of relationship. The IRS uses a multi-factor test, and Washington State applies the ABC test under RCW 51.08.195. Misclassification carries significant penalties.

### Lien Waivers & Payment Rights
**Q: What is a conditional lien waiver?**
A: A document signed by a contractor or subcontractor that waives lien rights only after payment has been received and cleared. Unlike unconditional waivers, conditional waivers protect the signer by keeping lien rights active until funds are verified.

**Q: What is a mechanics lien?**
A: A legal claim against a property by contractors, subcontractors, or material suppliers who have not been paid. In Washington, liens must be filed within 90 days of project completion (RCW 60.04).

### WIP Reporting & Revenue Recognition
**Q: What is a WIP report?**
A: A Work-in-Progress report tracks project financials by comparing costs incurred, revenue earned, and amounts billed. It reveals whether projects are over-billed or under-billed and is required by sureties and lenders.

**Q: What is percentage-of-completion accounting?**
A: A revenue recognition method that recognizes revenue and expenses proportionally as work is completed, rather than waiting until the project is finished. Required under ASC 606 for most construction contracts.
