Your P&L Says You Made Money. Your Bank Account Disagrees.

The Gap Between Profit and Cash

Your P&L and your bank account measure two different things.

Your P&L measures profitability. It records revenue when a job is completed and invoiced, and it records expenses when they're incurred. On paper, the timing looks reasonable.

Your bank account measures cash. Actual dollars available to spend right now.

In most industries, those two numbers track closely together. In collision repair, they don't. Because the cash cycle in this business has a built-in lag that works against you.

The Collision Shop Cash Timing Problem

Walk through a single repair order.

The car comes in. You order parts. Those parts go on your supplier statement. Depending on your terms, you've got 30 days before that bill comes due. That's the good part.

But now look at the other side of the equation.

Your technicians clock in two days later. They get paid in two weeks. Not when the car leaves, not when insurance pays. Two weeks from their last check, regardless.

Rent is due on the first. Your workers' comp premium drafts automatically. The electric bill comes in. These expenses don't time themselves around your cash receipts.

And here's the constraint that drives everything: you cannot issue a final invoice until the car rolls out the door. With average cycle times running 12 to 17 days right now, that means almost every car in your shop is sitting between intake and invoice at any given moment.

You're carrying the overhead, the labor cost, and eventually the parts bill. And none of it converts to cash until the car is done, invoiced, and the insurance company cuts a check. On their 30-day cycle.

Multiply that by 15 to 20 cars in process at the same time. You've got six figures of revenue your P&L says you earned, sitting in your bays, not in your account.

What the Market Is Doing to This Problem

The timing issue has always existed in collision repair. But three things happening right now are making it worse.

First, repairable claim volume is down. CCC data shows repairable claims are running 10.4% below where they were a year ago. Total loss rates have climbed to 22.8%. Fewer cars are coming through your door.

Second, the jobs that do come in cost more to complete. Parts prices are up over 6% year over year. More dollars going out before a single dollar comes in.

Third, cycle times are up. More supplements, more parts availability issues, more back-and-forth with adjusters. Every extra day a car sits in your shop is another day before you can invoice it.

The Cash Conversion Cycle

There's a simple framework for thinking about this. It's called the cash conversion cycle.

It measures the time between when you spend money and when you collect it.

In collision repair, it looks like this. You order parts on day one. Your tech starts work on day three. The car rolls out on day fifteen. You invoice on day fifteen. Insurance pays on day forty-five.

That's a 45-day cycle from first dollar out to last dollar in. With parts terms of 30 days, you've got a 15-day gap where you're fully exposed. And that's on a clean repair with no supplements.

Add a supplement cycle, and you might be looking at day fifty or beyond before cash hits your account.

Knowing your actual cash conversion cycle tells you two things: where the bottleneck is, and where you have leverage to tighten it.

What to Do With This

Start by mapping your own cycle.

How many days from parts order to car-out? How many days from invoice to payment, by payer type? What's your average WIP balance right now, and how does it compare to your monthly overhead?

Those three questions tell you more about your cash position than your P&L does.

I built a one-page worksheet that walks through this map. It covers your cash-in timeline by payer, your cash-out timeline by expense category, and the gap analysis that shows you exactly where cash is getting stuck.
