Frequently Asked Questions
Separating these costs provides clarity for your client and makes reconciliation easier. List labor as hourly or fixed-rate line items, group materials purchased specifically for the project, and separately invoice equipment rental or tool costs. For example, if you're installing electrical wiring, itemize installation labor apart from wire and conduit materials. This granularity protects both parties during audits, reduces payment disputes, and aligns with how general contractors track expenses for project accounting and budget reconciliation.
Yes, including your tax ID strengthens your professional standing and simplifies your client's compliance requirements. If you operate as a sole proprietor, include your Social Security Number (SSN); if you're an LLC, S-Corp, or C-Corp, use your Employer Identification Number (EIN). Many clients require this information before issuing a Form 1099-NEC, which reports your income to the IRS. Providing this information upfront prevents delays in payment or tax reporting and demonstrates you're running a legitimate business.
Retainage is when a client withholds a percentage—often 5–10%—of your invoice total until project completion. This practice protects general contractors by ensuring subcontractors finish work and address defects. Retainage should be specified in your subcontracting agreement before work begins; if not mentioned, ask explicitly. The retained amount is typically released 30–45 days after final approval. Understanding retainage upfront helps with cash flow planning and prevents surprises when payment arrives lower than expected.
The timing depends on your contract terms and project scope. For smaller projects, invoice upon completion and submit promptly to start payment processing. On larger projects, invoicing at defined milestones—such as project phases or monthly intervals—maintains steady cash flow and aligns with how general contractors manage payments. Include specific milestone descriptions on your invoice to match what was completed. Discuss your preferred invoicing schedule during contract negotiation; some clients require weekly submissions, others prefer monthly consolidation.
Create separate line items for equipment rental and permit costs rather than bundling them with labor. For equipment, specify the item (lift, tools, generators), duration, and daily or hourly rate; attach rental receipts if requested. For permits and fees, itemize them with the permit type and description. Both costs need clear documentation, especially if your contract specifies who bears these expenses. Reference your subcontracting agreement to confirm responsibility, then invoice accordingly to avoid payment delays or disputes.
Accept the payment methods your client prefers, but establish clear expectations upfront. Most general contractors pay by check or ACH bank transfer, so provide your banking details and mailing address. Some larger firms use payment portals; confirm whether they use these and set up your account accordingly. State your preferred payment method on your invoice with clear instructions. Faster payment methods reduce cash flow delays, which is critical when you've already invested in materials and labor upfront.
Use specific, measurable descriptions rather than vague summaries. Instead of "electrical work," write "electrical wiring installation—Phase 1, 40 hours at $75/hour." Include material quantities and unit costs: "Wire and conduit materials: 500 feet, $850." This specificity lets your client verify charges against the original proposal, reducing questioning and payment delays. Attach receipts for materials when possible. Detailed line items also create records for your business accounting and prevent disputes that slow payment cycles.
Create a separate invoice for each project, client, or contract to maintain clarity and simplify accounting. If you're doing multiple jobs for the same client, combine them on one invoice but use distinct groupings or sections for each project with its project code or name. Always reference the purchase order, project number, or contract number on your invoice. This prevents confusion when the client reconciles charges against individual project budgets and streamlines your bookkeeping.
