Garage door service is a high-volume, low-ticket business that lives or dies on the parts margin and technician productivity. Most shops we onboard cannot tell us the actual margin per ticket because parts revenue and labor revenue are mixed in the chart of accounts.

We work with residential garage door specialists and commercial overhead-door contractors.

What we handle

  • Parts vs labor revenue separation — so margin is visible by category.
  • Inventory tracking for springs, openers, sections.
  • Technician payroll with flat-rate or hourly handled correctly.
  • Job costing for install jobs.
  • After-hours dispatch tracked separately so margin reporting reflects premium revenue.
Field note: parts margin

A 4-truck residential garage door shop was running 38% gross margin reported. After we separated parts revenue (52% margin) from labor revenue (68% margin) and the cost of the bundled "service call" SKU (28% margin because of trip-charge underpricing), they raised the trip charge $25 and recovered 4 points of total margin in one quarter.

If / Then

If you do mostly residential service, Jobber or Housecall Pro plus monthly bookkeeping is the right setup.
If you carry inventory above $10K, perpetual inventory matters.
If you do new construction, separate that revenue stream — different margins.

The Bottom Line

Parts margin separated, real productivity per tech, after-hours priced right.

From $500/month.

Frequently asked questions

Software?

ServiceTitan for shops with 5+ techs, Jobber or Housecall Pro for smaller. We reconcile to QuickBooks.

How do you price after-hours?

We track after-hours revenue and after-hours labor separately, then calculate the actual after-hours margin. Most shops underprice the premium and we surface that during quarterly review.

Section 179 on a service truck?

Yes, qualifying work trucks immediate-expense in year 1 within annual limits.

Sales tax?

Parts are taxable in CO; labor is generally not if separately stated.
