Template Verification FAQ
Quick Definition
This template verification FAQ answers the most common questions from fabricators and homeowners.
Template verification is a quality-control process that checks digital countertop templates for errors before fabrication begins. SlabWise's 3-layer verification compares template measurements against the original quote, fabrication tolerances, and historical error patterns - catching mistakes that would otherwise result in costly remakes.
TL;DR
- A single countertop remake costs $1,500-$4,000 in material, labor, and customer disruption
- The average shop experiences 2-4 remakes per month from template errors
- SlabWise's 3-layer check catches 80-90% of errors before cutting starts
- Layer 1: Dimension check (template vs. quote measurements)
- Layer 2: Tolerance check (overhangs, clearances, critical dimensions)
- Layer 3: Pattern check (AI flags common mistakes based on historical data)
- Verification runs automatically when templates are uploaded - no manual review process
- Included in both Standard ($199/month) and Enterprise ($349/month) plans
Understanding Template Errors
What kinds of template errors cause remakes?
Template errors fall into several categories, all of which can lead to a countertop that doesn't fit the space:
| Error Type | Example | Frequency | Remake Cost |
|---|---|---|---|
| Dimension mismatch | Template shows 96" but actual counter is 98" | Common | $1,500-$2,500 |
| Missing cutout | Forgot to mark sink or cooktop location | Occasional | $2,000-$3,500 |
| Wrong overhang | 1" overhang templated, customer expected 1.5" | Common | $1,500-$2,000 |
| Incorrect seam location | Seam placed over unsupported span | Rare | $2,500-$4,000 |
| Wrong material thickness | 2cm templated, 3cm quoted | Occasional | $1,500-$3,000 |
| Wall angle error | Template didn't capture an out-of-square corner | Common | $1,500-$2,500 |
The most common errors are dimension mismatches and wrong overhangs - both of which are straightforward for software to catch but easy for a busy human to miss.
How often do template errors actually happen?
Industry data suggests that 5-10% of templates contain at least one error significant enough to affect the final product. For a shop doing 50 templates per month, that's 2.5-5 problematic templates.
Not every error leads to a full remake - some can be corrected during fabrication or worked around during installation. But when an error does result in a remake, the cost is immediate and painful: $1,500-$4,000 per incident for material replacement, re-fabrication labor, rescheduling the install, and managing the customer relationship.
Why do template errors happen?
Several contributing factors:
Rushed templaters. When your templater is running behind schedule (three kitchens in one day), speed takes priority over precision. A quick measurement gets rounded, a cutout gets missed, and nobody catches it until the stone is on the saw.
Communication gaps. The homeowner told the designer they want a undermount sink, but the templater measured for a drop-in. The quote says 3cm quartz, but the template file defaults to 2cm. These gaps are human coordination problems that software can flag.
Equipment issues. Digital templating systems (LT-2D3D, Proliner, etc.) are accurate, but only if calibrated correctly and operated properly. A laser that's drifted off calibration can introduce systematic errors across every measurement.
Scope changes. The homeowner decided to add a backsplash after the template was done. Or they moved the sink location. The change got communicated verbally but never updated in the template file.
The 3-Layer Verification Process
Layer 1: Dimension Check - How does it work?
When a template is uploaded to SlabWise, the system compares the template dimensions against the original quote dimensions. The comparison checks:
- Total linear footage
- Width at each section
- Overall square footage
- Cutout positions and sizes
If the template measurements differ from the quote by more than your configured tolerance (typically 1-2 inches for residential work), the system flags the discrepancy. Your team gets an alert showing exactly where the mismatch is and how large the difference is.
Example: Quote says kitchen counter is 96" x 25.5" with a 33" undermount sink. Template comes in showing 94" x 25.5" with a 33" sink. The 2-inch length discrepancy triggers a flag. Your team investigates - turns out the templater measured to the wrong reference point. Re-template catches the problem before $800 in quartz gets miscut.
Layer 2: Tolerance Check - What does it verify?
Beyond comparing template to quote, Layer 2 checks the template measurements against standard fabrication tolerances:
- Overhang distances - Are they within the structurally supported range? (Typically 6-10" without supports, up to 12-15" with brackets)
- Sink clearance - Is there enough material between the sink cutout and the edge? (Minimum 2-3" for structural integrity)
- Cooktop clearance - Same check for cooktop cutouts
- Seam locations - Are seams placed over supported areas? (Seams over dishwashers or unsupported spans are structural risks)
- Corner radii - Do inside corners meet minimum radius requirements for the material?
If any measurement falls outside tolerance, the system flags it with a specific explanation: "Sink cutout is 1.5" from front edge - minimum recommended clearance is 2.5" for this material."
Layer 3: Pattern Check - What does AI catch that humans miss?
This is where SlabWise's template verification goes beyond simple measurement comparison. Layer 3 uses historical data from thousands of verified templates to identify patterns that correlate with errors:
- Missing cutouts - The quote includes a cooktop cutout, but the template has no cooktop opening. This catches the most expensive error: fabricating a countertop with a missing hole that requires a complete recut.
- Unusual dimensions - A bathroom vanity template showing 84" width when 90% of vanities in that configuration are 48-72". Not necessarily wrong, but worth verifying.
- Thickness mismatches - The template file specifies 2cm but the quote and material selection are for 3cm.
- Edge profile conflicts - A mitered edge specified where the template geometry makes mitering physically impractical.
- Backsplash discrepancies - Quote includes backsplash but template has no backsplash measurements.
The pattern check doesn't automatically reject templates - it flags them for human review with an explanation of the concern. Your team makes the final call.
Using Template Verification
How do I submit templates for verification?
Upload the digital template file directly to the job in SlabWise. Supported formats include files from major digital templating systems (LT-2D3D, Proliner, etc.) as well as standard DXF files. Verification runs automatically on upload - no separate step required.
What happens when a template is flagged?
The job moves to a "verification pending" status. Your team sees:
- Which layer flagged the template (1, 2, or 3)
- The specific issue identified
- The measured value vs. expected value
- A recommendation (re-template, verify with customer, or adjust the quote)
Your team reviews the flag, investigates if needed (calling the templater, checking the quote, contacting the customer), and either approves the template to proceed or orders a re-template.
How long does verification take?
The automated check runs in seconds. The human review (when flagged) depends on your team's responsiveness. Most shops resolve flags within 2-4 hours. The key is that verification happens before the slab reaches the saw - when changes are free instead of costing $1,500+.
Can I adjust the tolerance settings?
Yes. Every shop has different standards. SlabWise lets you configure:
- Dimension tolerance (how much mismatch triggers a flag)
- Overhang limits
- Minimum clearances for cutouts
- Material-specific rules (marble may need tighter tolerances than granite due to fragility)
Does verification work with paper templates?
Not directly. Verification requires digital template data (dimensions, cutout positions) to run the automated checks. If your shop still uses physical templates, you'd need to digitize the measurements before verification can run.
That said, most shops have moved to digital templating systems (LT-2D3D, Proliner, or similar). If you're still on paper, moving to digital templating is worth considering independently - the accuracy improvement alone reduces errors significantly.
ROI and Results
How much does template verification save?
The math is straightforward. Each remake you prevent is $1,500-$4,000 in savings:
| Shop Size | Monthly Remakes (before) | Monthly Remakes (after) | Remakes Prevented | Monthly Savings |
|---|---|---|---|---|
| Small (20 jobs/month) | 1-2 | 0-0.5 | 1-1.5 | $1,500-$6,000 |
| Medium (50 jobs/month) | 2-4 | 0.5-1 | 1.5-3 | $2,250-$12,000 |
| Large (100+ jobs/month) | 4-8 | 1-2 | 3-6 | $4,500-$24,000 |
Even one prevented remake per month justifies the entire SlabWise subscription for most shops.
What percentage of errors does verification catch?
Based on SlabWise data, the 3-layer system catches 80-90% of significant template errors before fabrication. The remaining 10-20% are typically issues that don't manifest in the template data - like a wall that's out of plumb (which affects installation fit but doesn't show in a top-down template).
Does verification slow down my production?
No. The automated checks take seconds. The only potential delay is when a template is flagged for review - but that delay is intentional. Spending 30 minutes investigating a flag is vastly preferable to spending 2 days remaking a countertop.
In practice, most shops find that verification actually speeds up production by reducing the rework that causes the biggest scheduling disruptions.
Integration with Other Features
How does verification connect to slab nesting?
Templates must pass verification before they enter the nesting queue. This ensures the nesting algorithm is working with accurate dimensions, which produces cutting layouts that actually fit the installation space.
Does verification affect customer communication?
When a template is flagged, SlabWise can notify the relevant parties automatically:
- The templater - to correct or verify the measurement
- The office - to coordinate the resolution
- The customer or contractor - if a re-template visit is needed
This keeps everyone informed without manual phone tag.
Can I track verification metrics over time?
Yes. SlabWise reports on:
- Total templates processed
- Flag rate (percentage of templates flagged)
- Flag type distribution (which layers catch the most issues)
- Resolution time (how quickly flags are resolved)
- Remake rate before and after verification implementation
This data helps identify training needs for your templating team and track the financial impact of verification.
Frequently Asked Questions
Is template verification worth it for a shop that rarely has remakes?
If you're averaging fewer than one remake per quarter, your templaters are doing excellent work. Verification still provides value as a safety net - the cost of one prevented remake covers a year of the subscription. Think of it as insurance.
Can verification catch errors from old or miscalibrated templating equipment?
Layer 2 (tolerance checks) can flag systematic issues like consistently short measurements that might indicate calibration drift. If multiple templates from the same device are getting flagged for similar dimension offsets, that's a strong signal to check your equipment.
What templating systems are compatible?
SlabWise accepts files from major digital templating platforms including LT-2D3D, Proliner, and standard DXF output from other systems. If you're unsure about compatibility, the support team can verify your specific setup during the trial period.
Does verification replace the need for experienced templaters?
No. Verification is a safety net, not a substitute for skill. A good templater produces clean, accurate templates. Verification catches the occasional mistake that even good templaters make - especially under time pressure.
Can verification flag aesthetic issues, not just dimensional ones?
To a limited degree. Layer 3 (pattern check) can flag unusual seam placements or vein direction concerns, but aesthetic judgment ultimately requires human review. The system flags potential issues; your team decides if they're actual problems.
What if I disagree with a verification flag?
You have full authority to override any flag. The system flags potential issues - it doesn't prevent cutting. If your team determines the flag is a false positive (the template is correct despite the concern), approve it and proceed.
How does this work for commercial jobs with unusual dimensions?
Commercial jobs often have dimensions that fall outside residential norms. You can configure material-specific and job-type-specific tolerance ranges. A 20-foot reception desk won't get flagged just because it's longer than a typical kitchen counter.
Can I see a history of all verification flags?
Yes. Every flag, resolution, and override is logged. This creates an audit trail that's useful for quality management, team training, and identifying recurring issues.
Does verification cost extra beyond the subscription?
No. Template verification is included in both SlabWise Standard ($199/month) and Enterprise ($349/month) with no per-template charges.
What's the false positive rate?
Typically 10-15% of flags are false positives (the template is actually fine). This rate decreases as the system processes more of your shop's templates and learns your patterns. A 10% false positive rate is a reasonable trade-off for catching 80-90% of real errors.
Catch Errors Before They Become Remakes
Every template that passes through SlabWise's 3-layer verification is one less chance of a $1,500-$4,000 mistake. The check takes seconds. The savings last all month.
