NAGS Pricing Explained: How to Stop Undercharging for Glass

What Is NAGS Pricing?

NAGS (National Auto Glass Specifications) is the industry standard database for auto glass part numbers, dimensions, and pricing. Every windshield, door glass, and back glass in the NAGS catalog has a part number and an associated list price — but the list price isn't what you charge or what insurers pay.

The actual transaction price is calculated as:

NAGS List Price × Multiplier = Net Part Price

The multiplier varies by insurer, state, and shop negotiation. Typical network multipliers run between 0.52 and 0.72 of list. If you're not tracking your effective multiplier per insurer, you're flying blind.

The Three Numbers That Matter

1. List Price — The published NAGS price for the part. Changes quarterly. Always verify against the current NAGS catalog — shops that use outdated pricing leave money on the table.

2. Labor Hours — NAGS assigns standard labor times (in tenths of hours) for each part. Insurers pay against this standard, not your actual time. A replacement that takes your tech 90 minutes may only pay 1.2 labor hours.

3. Kit Allowance — Adhesive, primers, and moldings are separate from the glass price. Most insurers pay a flat kit allowance ($15–$35) that rarely covers your actual cost. Document your kit costs and push back if the allowance is unreasonable.

Common Billing Mistakes

• Not charging for ADAS recalibration — Always add it as a line item when required. Most insurers cover it under the same claim.
• Missing mouldings and clips — These are separate NAGS line items. Don't bundle them into the glass price.
• Accepting network pricing without review — TPA networks set multipliers that erode margin. Know your floor before accepting any job.
• Skipping chip-to-replacement documentation — If a repair fails and escalates to replacement, document the original chip repair attempt. Some insurers contest replacements without this trail.

How GlassQuote Pro Handles NAGS

GlassQuote Pro integrates directly with the NAGS API to pull current pricing at quote time. The system:

• Auto-populates part numbers from VIN lookup
• Applies your configured multiplier per insurer
• Calculates kit allowances and labor separately
• Flags ADAS recalibration requirements based on vehicle make/model
• Generates insurance-ready invoices with all required line items

The result: every quote is accurate, every invoice captures maximum reimbursement, and your team spends less time on paperwork.

Takeaway

NAGS pricing isn't complicated once you understand the framework. The shops that consistently capture maximum reimbursement are the ones that treat pricing as a skill, not an afterthought. Audit your last 30 jobs — if your effective multiplier is below 0.60, you're leaving significant revenue behind.
