Running a construction business in San Diego means balancing job sites, subcontractors, material costs, and client payments—all while trying to maintain steady cash flow. One of the most overlooked areas that can make or break your bottom line? Invoicing.
At Accounting Fresh CPA Inc., we help contractors and builders simplify their financial systems, automate billing, and gain real-time visibility into project profitability using QuickBooks Online (QBO). Here’s how to master construction invoicing for smoother operations and healthier cash flow.
1. Structure Your Invoices by Project and Phase
Every construction project involves multiple moving parts—demolition, framing, electrical, plumbing, finishes, and more. Instead of sending one lump-sum invoice, break it down by project phase or milestone.
This not only gives your clients transparency but also makes it easier to track progress payments and manage retainage.
Pro Tip: In QuickBooks Online, use Progress Invoicing to bill clients for a percentage of work completed. It helps you stay organized and ensures your team gets paid as each milestone is met.
2. Automate Retainage Tracking
Many contractors in San Diego work under contracts where retainage (5–10%) is withheld until the project is completed. If this isn’t tracked properly, it can cause major cash flow headaches.
With QBO Projects, you can separate retainage from billable income—ensuring your P&L stays accurate and you can easily identify what’s due back to you once the job closes.
3. Capture Change Orders in Real Time
Change orders are inevitable in construction—but missed ones can eat into profit.
Make it standard practice to log change orders immediately in QuickBooks Online. Add supporting documentation (emails, photos, estimates) to keep your client records airtight and prevent disputes down the line.
Automating this step helps avoid “lost revenue” from unbilled changes, especially when multiple trades or vendors are involved.
4. Align Your Payment Terms with Cash Flow Needs
San Diego contractors often face long payment cycles—especially when working with large developers or government contracts. Consider shorter payment terms (e.g., Net 15 or 30), and use QuickBooks Online’s recurring invoice reminders to prompt clients automatically.
Offering ACH or credit card payments through QuickBooks Payments can also speed up collections and reduce manual follow-ups.
5. Integrate Job Costing with Invoicing
Accurate job costing ensures your invoices reflect true costs, including materials, labor, and subcontractor expenses.
With QBO Projects, you can track profitability by job in real time and adjust your pricing or bidding strategies accordingly. For contractors juggling multiple projects, this visibility is key to avoiding underbilling or cost overruns.
6. Keep Your Books Clean and Audit-Ready
Messy invoices lead to messy books.
Regularly reconciling your QBO accounts and reviewing open invoices helps identify duplicates, missing retainage, or outstanding balances. A monthly reconciliation process ensures your financials are always ready for bonding applications, loan reviews, or tax filings.
Partnering with a San Diego-based CPA firm that specializes in construction accounting—like Accounting Fresh—can help you stay compliant and confident.
