Tracking Your Money & Keeping Records

Understanding Cash Flow

Cash flow is the movement of money in and out of your general contracting (GC) business. It matters more than “profit” because your crew still needs to be paid even if a customer is slow to approve invoices. In construction, cash flow can swing hard due to billing timing, retainage, change orders, and production delays.

Think of your business like a jobsite pipeline. Cash goes in when you invoice and collect. Cash goes out when you pay subs, buy materials, cover payroll, fuel the truck, and handle overhead (insurance, rent, utilities). If your outflow is higher than your inflow for long enough, your pipeline runs dry—even if you’re busy and sales look good.

The Importance of Basic Records

Basic records are your control panel. Without them, you’re guessing. With them, you can answer the questions owners actually need:
- Which jobs are truly funding the business?
- Are we losing money somewhere before the WIP (work-in-progress) turns into a problem?
- How much cash is trapped in retainage?
- How long does it take from “we finished the scope” to “we got paid”?

In GC work, records also keep you protected during disputes: approvals, change orders, draw schedules, and subcontractor agreement details. When you can show what was agreed to and when, you reduce risk and speed up collections.

Real-World Scenario

Let’s say you’re building custom additions and doing multiple remodels. Job A is on track, but your draw schedule requires an inspection and release of payment. Job B is behind because of an unapproved material substitution. Your sales team quoted a change order, but it’s waiting on the client’s signature.

If you track cash flow weekly, you’ll see:
- You invoiced Job A, but cash hasn’t arrived yet.
- Job B is still consuming money because subs and materials are moving.
- Your change order approval time is pushing costs into next month.

That’s the difference between “we’re busy” and “we’re funded.”

The GC Bootstrapper’s Ledger

You don’t need complex accounting software to start. Use a simple weekly ledger to track cash movement tied to construction reality:
- Weekly cash in: deposits, progress payments, retainage releases, change order payments.
- Weekly cash out: payroll, subs, materials, equipment rentals, fuel, insurance.
- WIP snapshot: what you billed vs. what you still expect to collect, based on your draw schedule.

This practice reveals your burn rate (how quickly you’re spending cash) and your cash runway (how long you can operate with current cash if collections slow). It also forces discipline around billing cadence and documentation.

Forecasting and Decision Making

Forecasting lets you decide, not hope. In construction, forecasting isn’t about guessing the future—it’s about building a plan around known dates:
- Next draw inspection dates
- Expected change order approval dates
- Subcontractor payment schedules
- Material lead times

Use that to make decisions like:
- Hiring: Can you afford another lead carpenter until the next draw hits?
- Scope changes: If a change order is delayed, do you slow work-in-progress or fund it separately?
- Marketing: If runway is short, focus on jobs that pay faster, like smaller remodels with quicker draw schedules.

If you follow NHAB-style best practices for operational discipline and Buildertrend/BIM-minded workflow visibility, your forecasts become more accurate because your job data is cleaner.

Conclusion

For a general contractor, cash flow tracking is jobsite survival. It keeps payroll steady, reduces borrowing, and helps you spot trouble jobs before they drain the business. Pair weekly cash review with simple forecasting, and you’ll know whether your next month is funded—not just “booked.”
