Bookkeeping for Landscaping Companies in Houston: What to Track and Why

A landscaping company owner based out of Katy started with a single truck and a two-man crew doing residential lawn maintenance. Within four years, he had six trucks, 18 employees, commercial contracts, and a full irrigation installation division. He was making money (he knew that because his bank balance kept going up. But he couldn’t tell you which division was most profitable, whether a specific commercial contract was worth renewing, or why his cash flow felt tight every January even though 2025 was his best year on paper.

The answer was always in the books. His books just weren’t built for the business he was running.

Landscaping and lawn care bookkeeping has features that general small business accounting misses. Job costing, equipment management, seasonal cash flow, and a specific labor cost structure all require intentional setup.

Job Costing: The Core of Landscaping Financials

Every landscaping job has costs: labor, materials, fuel, equipment time, subcontractors. Job costing means tracking those costs per job so you know whether a specific contract is making money) not just whether the business overall is profitable.

This matters because landscaping margins vary dramatically by job type. Routine maintenance (mowing, edging, blowing) typically runs 50-60% gross margin with an experienced crew. Irrigation installation is labor-intensive and equipment-heavy; margins can compress to 25-35% if the job is scoped wrong. Tree removal has high equipment and subcontractor costs. If you’re not tracking by job, the profitable work subsidizes the unprofitable work and you never find out until a contract renews at a bad rate.

How to set it up in QuickBooks. Use class tracking or job tracking (QuickBooks Projects or the Jobs feature) to tag every expense and revenue transaction to the specific job or contract. Labor hours entered on timecards get allocated per job. Materials purchased for a specific job are coded to that job. Over time, you build actual cost data per job type that informs your estimates and pricing.

Labor: The Dominant Cost

For a Houston landscaping company, labor is typically 30-40% of revenue. Managing it correctly means:

Tracking hours by job. Timecards or a mobile time-tracking app. Crews should clock in and out per job, not just per day. This lets you calculate actual labor cost per job against estimated labor cost. If your estimate assumed 3 hours and the crew took 4.5, you need to know that (not six months later, but this week.

Overtime. In Texas, overtime for non-exempt employees is required under federal law (FLSA) for hours over 40 in a week. Landscaping work is seasonal, which means spring and summer can generate significant overtime exposure. Overtime premiums need to be in your labor cost estimates; they often aren’t.

H-2A and 1099 workers. Many Houston landscaping companies use seasonal workers on H-2A visas or 1099 subcontractors for peak season. H-2A workers have specific wage requirements and housing compliance costs that need to be accounted for. 1099 subcontractors over $600 in a year require a 1099-NEC. Misclassifying employees as contractors is an audit risk in landscaping) particularly if you control their schedule, require them to use your equipment, and direct their work.

Equipment: Depreciation and Maintenance

A commercial landscaping company might have $150,000-$400,000 in equipment: mowers, trucks, trailers, irrigation tools, skid steers. This equipment depreciates. How you handle that depreciation affects your tax liability and your true understanding of costs.

Section 179 and bonus depreciation allow you to deduct the full cost of qualifying equipment in the year of purchase rather than depreciating it over its useful life. This is a powerful tax tool, but using it aggressively one year creates lower depreciation deductions in future years (which means higher taxable income later. The strategy needs to fit your cash flow and tax situation.

Maintenance vs. capital improvement. Replacing a mower blade is a maintenance expense. Rebuilding a mower engine is a capital improvement that adds to the asset’s value and should be depreciated. The line matters for your tax return.

Equipment per-job cost allocation. If you want accurate job costing, you need to allocate equipment costs per hour of use. A commercial mower with an annual cost of $8,400 (depreciation + maintenance) costs about $35/hour at 240 hours of annual use. That per-hour cost should be in your estimate for every commercial mowing job.

Seasonal Cash Flow

Houston landscaping has a winter slowdown. Residential maintenance schedules often drop to every-other-week or monthly from November through February. Revenue dips. But fixed costs) truck payments, insurance, shop rent, don’t.

This is predictable, and it should be planned for. The two tools:

Monthly cash flow projection. Build a 12-month cash flow forecast at the start of each year showing expected revenue by month, fixed costs, and variable costs. Identify the months where cash is tight. Build a reserve during the April-October peak to cover the gap.

Retainer contracts. Selling annual maintenance contracts (52 equal monthly payments for 12 months of service) smooths revenue. Instead of collecting more in April and less in January, you collect an equal amount every month. For commercial clients especially, annual contracts with fixed monthly billing are worth a pricing concession to get the cash flow stability.

What the Numbers Said

The Katy landscaping owner’s books took about six weeks to clean up and restructure. Once job costing was in place, the picture was clear: commercial maintenance contracts were making 52% gross margin. Irrigation installation was running 28% because his material estimates were consistently low by 12-15%. Residential mowing was at 61% gross margin but had the highest crew turnover because of how routes were structured.

He renewed his commercial contracts. He raised his irrigation installation prices 18%. He restructured his residential routes to reduce drive time. And he built a cash reserve policy: 8% of gross revenue set aside monthly into a separate account, only drawn on in Q1 if needed.

That’s what clean books make possible.
