QuickBooks Integration Guide for Countertop Fabricators

QuickBooks integration for countertop fabricators means connecting your shop management software to QuickBooks Online or Desktop so that invoices, payments, expenses, and job costs sync automatically---eliminating double entry and giving you accurate profit-per-job numbers without manual bookkeeping. Most fabrication shops using integrated systems save 10-15 hours per month on accounting tasks.

TL;DR

• QuickBooks Online is the preferred version for 85% of fab shops under $5M in revenue
• Proper chart of accounts setup takes 2-3 hours and prevents months of cleanup later
• Job costing in QuickBooks requires tracking materials, labor, and overhead per job
• Integration with shop management software eliminates 10-15 hours/month of double entry
• Material inventory tracking should use average cost method for stone slabs
• Fabrication shops need 12-15 custom accounts beyond QuickBooks defaults
• Monthly reconciliation should take under 2 hours with a proper setup

Job Costing: Tracking Profit Per Job

Job costing is the single most valuable QuickBooks feature for fabricators. Without it, you know your total monthly profit but have no idea which jobs make money and which lose money.

How to Structure Job Costing

Step 1: Create each countertop job as a "Customer:Project" in QuickBooks. Use a naming convention like "Smith-Kitchen-2026-0215" (Customer-Project-Year-Month/Day).

Step 2: Assign every expense to a specific job:

• Slab cost: Tag the slab purchase to the job
• Labor hours: Track fabrication and installation hours per job
• Consumables: Allocate a standard percentage (typically 3-5% of material cost)
• Delivery: Assign actual delivery cost or a flat rate per job

Step 3: Compare actual costs against the estimate:

Cost Category	Estimated	Actual	Variance
Calacatta Gold Quartz (48 sq ft)	$4,080	$4,080	$0
Fabrication Labor (6 hrs @ $35)	$210	$245	+$35
Edge Work (22 lin ft)	$132	$132	$0
Sink Cutout	$50	$50	$0
Installation (4 hrs @ $40)	$160	$200	+$40
Consumables (5%)	$204	$210	+$6
Total Job Cost	$4,836	$4,917	+$81
Revenue	$6,394	$6,394
Gross Profit	$1,558 (24.4%)	$1,477 (23.1%)	-$81

This job-level visibility shows you which material types, job sizes, and edge profiles are most profitable---and which are quietly draining margin.

Slab Inventory Tracking

Stone slabs are your biggest expense and most complex inventory item. Each slab is unique (color variations, lot numbers, dimensions), which makes standard inventory tracking insufficient.

Average Cost Method

QuickBooks supports FIFO and average cost methods. For fabrication shops, average cost works best because:

• You often buy multiple slabs of the same material at different prices
• Remnants from different slabs get mixed together
• Material costs fluctuate with market pricing

Example: You buy 3 slabs of White Zeus quartz:

• Slab 1: $1,800 (purchased January)
• Slab 2: $1,950 (purchased February)
• Slab 3: $1,850 (purchased March)
• Average cost: $1,867 per slab

When you use one slab for a job, QuickBooks records $1,867 as the material cost regardless of which physical slab you cut.

Tracking Remnants

Create a separate inventory item called "Remnants - [Material Type]" and transfer partial slab value when you have usable remnants. If you cut 35 sq ft from a 55 sq ft slab, move the remaining 20 sq ft value to your remnant inventory.

Integrating QuickBooks with Shop Management Software

Why Integration Matters

Without integration, your workflow looks like this:

1. Create quote in shop management software
2. Re-type the quote details into QuickBooks as an estimate
3. Convert to invoice in QuickBooks manually
4. Record payment in QuickBooks manually
5. Enter material costs and labor separately

That is 5 data entry points per job. At 40 jobs per month, you are looking at 200 manual entries---each one a chance for error.

How SlabWise-QuickBooks Integration Works

With an integrated system:

1. Create quote in SlabWise (customer approves online)
2. Invoice auto-generates in QuickBooks with correct line items
3. Payment recorded in SlabWise syncs to QuickBooks automatically
4. Material costs from slab allocation sync to the job
5. Labor hours from time tracking flow into job costing

Result: Zero double entry. One data entry point per job instead of five.

Integration Sync Settings

Data Type	Sync Direction	Frequency
Customer Info	SlabWise → QuickBooks	Real-time
Invoices	SlabWise → QuickBooks	On creation
Payments	SlabWise → QuickBooks	On receipt
Material Costs	SlabWise → QuickBooks	On slab allocation
Products/Services	Two-way	Daily

Monthly Bookkeeping Checklist for Fabricators

Run through this checklist on the first week of each month:

• Reconcile bank accounts and credit cards
• Review open invoices and AR aging (target: under 20 days)
• Verify slab inventory counts match physical inventory
• Review job profitability report for completed jobs
• Check COGS percentage (target: 55-65% for most shops)
• Reconcile payroll to labor cost allocations
• Review and categorize any uncategorized expenses
• Run P&L by month and compare to prior month
• Review remnant inventory value and write off unsaleable pieces
• Back up data (Desktop) or verify sync status (Online)

Common QuickBooks Mistakes Fabricators Make

Mistake 1: Not using job costing. Without it, you are flying blind on which jobs are profitable. A shop doing $1.2M in revenue might have 30% of jobs running below breakeven and never know it.

Mistake 2: Recording slab purchases as expenses instead of inventory. This inflates your expenses in the month you buy and understates them in the month you use the material. COGS should reflect materials used, not materials purchased.

Mistake 3: Not separating fabrication labor from overhead labor. Your CNC operator's wages are COGS. Your office manager's wages are overhead. Mixing them makes your gross margin calculation meaningless.

Mistake 4: Ignoring remnant value. A $2,000 slab that yields a $1,200 countertop and $400 in usable remnants has a true material cost of $800 for that job, not $2,000.

FAQ

Is QuickBooks Online or Desktop better for a fabrication shop?

QuickBooks Online Plus is the better choice for most shops. It supports job costing, integrates with shop management software through APIs, and allows multiple users to access data from anywhere. Desktop is only preferable if you need offline access or have existing Desktop workflows you cannot migrate.

How much does QuickBooks cost for a countertop fabricator?

QuickBooks Online Plus runs $90/month and covers most fabrication shop needs. If you need more than 5 users or advanced reporting, QuickBooks Advanced is $200/month. Factor in $500-$1,500 for initial setup if you hire a bookkeeper familiar with fabrication businesses.

Can QuickBooks track individual slab inventory?

QuickBooks can track slab types as inventory items with quantities and average costs, but it does not natively handle individual slab tracking with lot numbers, dimensions, and photos. For slab-level tracking, you need a fabrication-specific tool like SlabWise that syncs inventory data to QuickBooks for the financial side.

How do I handle deposits and progress payments in QuickBooks?

Record deposits as partial payments against the full invoice. In QuickBooks Online, create the full invoice when the job is sold, then record each payment (50% deposit, 40% at template, 10% at install) against that invoice. The open balance automatically updates to show what is still owed.

What should my gross profit margin be as a fabricator?

Healthy fabrication shops target 35-45% gross profit margin. If your QuickBooks reports show gross margin below 30%, review your material costs, labor efficiency, and pricing. Job costing reports will reveal which specific job types or materials are dragging down your average.

How often should I reconcile my QuickBooks accounts?

Reconcile bank accounts and credit cards monthly, within the first week of the following month. If you process a high volume of transactions (over 200/month), consider weekly reconciliation. The longer you wait, the harder it is to find and fix discrepancies.

Do I need a bookkeeper or can I manage QuickBooks myself?

Shops under $500K in annual revenue can often manage QuickBooks themselves with proper initial setup. Once you pass $500K, a part-time bookkeeper (5-10 hours/month, $300-$600) pays for itself by catching errors, maintaining clean records, and freeing your time for production management.

How do I track fabrication waste and scrap in QuickBooks?

Create an expense account called "Material Waste/Scrap." When a slab breaks or a cut goes wrong, transfer the material value from inventory to this expense account. Track this monthly as a percentage of total material costs. Industry average is 10-15% waste; AI-optimized nesting can reduce this to 5-8%.

Connect Your Shop to QuickBooks Automatically

SlabWise syncs your quotes, invoices, payments, and material costs directly to QuickBooks---no double entry, no data mismatches. Every job flows from quote to payment with full financial tracking built in.
