Estimate Scrubbing

The Software Default That's Costing You $800 a Car

Table of five CCC ONE not-included operations: corrosion protection, seam sealer, masking, DTC research, and single-use fasteners

The CCC ONE default not-included operations list is one of the most expensive settings most shop owners have never looked at. Your estimator isn't always making a judgment call when they leave a line off the estimate. Sometimes the software already made it for them.

We covered the structural reason for this in yesterday's post on incomplete estimates. This post goes one level deeper: five specific operation categories where CCC ONE defaults to not-included, what each one is worth, and what it looks like to bill for them correctly.

What the P-Pages Actually Say About Software Defaults

The MOTOR Guide to Estimating, the P-pages, is the document that defines what is and isn't included in CCC ONE's labor times. It is publicly accessible through the DEG (degweb.org) and through SCRS. The SCRS Guide to Complete Repair Planning documents over 800 not-included operations referenced across the major estimating platforms.

Most of these are not obscure procedures. They are standard operations that happen on almost every structural repair. The problem is that the P-pages are rarely read front to back. Estimators learn by doing, and what the software produces is treated as what the job costs. The operations that never appear on screen are the ones that never get billed.

Here are five categories where the P-pages are explicit and where shops consistently leave money on the table.

Five operation categories that CCC ONE defaults to not-included, each documented as billable and separate from calculated labor time.

Five Lines Your Software Isn't Writing for You

Corrosion protection application. The P-pages are unambiguous: restoring corrosion protection after structural repair is not included in the structural labor time. CIC's January 2025 review of P-page updates confirmed this language remains current across the CCC system. On any panel that gets welded, cut, or bare metal exposed, the corrosion protection step is a separate billable operation. On a 2022 Nissan Sentra with a rear quarter panel replacement, that's a line your estimator has to add manually. The software won't put it there.

Additional seam sealer on welded panels. The DEG has published this one explicitly: additional seam sealer on welded panels is not included. The P-pages language is specific. Replacing seam sealer that was removed with the part is addressed in the base time. Any additional seam sealer, meaning the OEM-specified application on the new panel or weld seam, requires an on-the-spot evaluation and a manual line entry. This is separate from, and in addition to, the base R&R time. Shops that don't add it are donating it.

Masking for seam sealer application. The DEG also documents this one. When seam sealer is applied to areas adjacent to a finished panel, masking is required to protect the finish. That masking operation is not included in any calculated labor time. It is a third separate line that most estimates never show.

DTC research time. The 2026 "Who Pays for What?" survey found that 40% of shops are not billing for DTC research time at all, separate from the scan charge. Of those who do bill it, only 21% get paid always or most of the time by the eight largest national insurers, but 46% get paid at least some of the time. The shops not billing for it are getting paid exactly that: nothing. On a 2024 Kia Telluride with multiple fault codes after a front-end collision, researching those codes is documented time that can be billed. It doesn't appear on a standard estimate unless someone adds it.

Single-use fasteners on structural components. Any OEM that publishes torque-to-yield bolt specifications, and most do, classifies those fasteners as single-use. They cannot be reinstalled after removal. The part cost is typically in the $15 to $40 range per fastener, but a structural repair involving subframe components can have eight to twelve of them. RepairLogic data puts the average miss at $31 per repair order. Add them up across a week of work and you'll see a number that shouldn't be zero.

Each stage of a structural repair generates not-included operations. Identifying them before the estimate leaves the building is the difference between complete billing and partial payment.

What Your Estimates Look Like Right Now

Here is the self-diagnostic. Pull your last 10 estimates. Go through each one and answer these questions: How many include a corrosion protection line? How many include a seam sealer line on any panel replacement? How many include masking for seam sealer? How many include DTC research time as a separate line from the scan? How many include single-use fasteners on any structural component?

If the answer to most of those is zero, that is not because the work wasn't done. It is because no one added those lines. The operations happened on the car. They just didn't make it onto the estimate.

That gap is what the $800 figure represents. Not an edge case on a complex repair. The predictable, consistent result of sending out estimates that start and stop at what the software produces, without layering in what the P-pages say is also required.

The Bottom Line

The P-pages exist because the software knows it doesn't cover everything. That's not a secret. The documentation is public, the DEG publishes updates, and the SCRS has been saying this for years. The shops that close this gap don't have smarter estimators. They have a process that runs the P-page check on every estimate before it leaves the building. That process is learnable. The defaults don't have to stay.

Frequently Asked Questions

What operations does CCC ONE default to not-included?
CCC ONE defaults to not-included for hundreds of operations documented in the MOTOR Guide to Estimating (P-pages). The most commonly missed categories are corrosion protection after structural repair, additional seam sealer on welded panels, masking for seam sealer application, DTC research time beyond the scan charge, and single-use fasteners on structural components. Each of these is a billable, documented operation that will not appear on a standard estimate output.
How do I find not-included operations in CCC ONE?
The MOTOR Guide to Estimating (P-pages) is accessible through the CCC ONE platform and through the DEG at degweb.org. The SCRS Guide to Complete Repair Planning also documents over 800 not-included operations across all major estimating platforms. Review the P-pages for each operation category on the estimate and cross-reference against what your estimate currently shows. Any P-page operation that is present on the car but absent from the estimate is a line that needs to be added with documentation.
Is corrosion protection included in CCC ONE repair time?
No. CIC's January 2025 P-page review confirmed that corrosion protection application remains outside calculated labor time in the CCC system. Any exposure of bare metal during structural repair requires corrosion protection, and that operation must be added as a separate line item on the estimate. The P-pages are explicit on this, and it applies to every panel that is welded, cut, or has bare metal exposed during the repair.
Why do so many collision repair estimates miss the same operations?
Estimating software is built to produce a starting point based on visible damage, not a complete scope of OEM-required procedures. Operations like seam sealer, corrosion protection, and DTC research don't show up in the default output because they fall outside the standardized labor times the software uses. Estimators learn by using the software and never see these operations unless they've been trained to look for them in the P-pages.
What is the MOTOR Guide to Estimating and where can I access it?
The MOTOR Guide to Estimating, also called the P-pages, defines what operations are and aren't included in CCC ONE's built-in labor times. It is accessible through the CCC ONE estimating platform and through the DEG (Database Enhancement Gateway) at degweb.org. The SCRS at scrs.com also maintains estimating tips and references to specific P-page guidance that shops can use to document not-included operations.
