Landscaping: A Seasonal Business That Needs Year-Round Bookkeeping

Landscaping businesses experience significant seasonal variation. Spring and autumn are typically peak periods, summer can be strong for maintenance but tough for physical labour, and winter often slows to a crawl. This makes financial planning and bookkeeping particularly important.

Good bookkeeping helps you build cash reserves during busy months, manage expenses during quiet periods, and make informed decisions about equipment, staff, and growth.

Revenue Streams

Most landscaping businesses have two main revenue streams:

Project Work

Design and build projects - new gardens, retaining walls, paving, decking, irrigation systems, and outdoor living spaces. These are larger, one-off jobs with higher revenue and higher costs.

Track project revenue using job costing. Each project should have a unique identifier, and all revenue and costs should be tagged to that project. This is the only way to know whether your projects are actually profitable.

Maintenance Contracts

Recurring lawn mowing, hedge trimming, garden maintenance, and property upkeep. This revenue is steadier and more predictable.

Set up recurring invoices for maintenance contracts. Track revenue by client so you can quickly identify if a client drops off or a contract is underperforming.

Job Costing for Landscapers

Job costing is essential for project work. Without it, you are guessing at profitability.

What to Track Per Project

Materials - Plants, soil, mulch, pavers, timber, stone, irrigation components, and every other material. Record the actual cost, not the quoted amount.

Labour - Your own time plus employee or subcontractor costs. Be honest about valuing your own time - if you spend 40 hours on a project but do not count your labour, the profit is an illusion.

Equipment - Excavator hire, truck use, trailer costs, tool wear. Allocate these costs to the project.

Subcontractors - Electricians, plumbers, arborists, concreting contractors. Track each subcontractor payment against the relevant project.

Waste removal - Tip fees and skip bin hire. These add up quickly on large projects.

Monitoring Project Profitability

Run a project profitability report at the end of each job. Compare actual costs to your quote:

  • Were materials more expensive than estimated?
  • Did labour take longer than planned?
  • Were there variations or extras?
  • What was the final margin?

Use this information to improve your quoting accuracy on future projects. Over time, you build a reliable picture of your true costs, which means more accurate quotes and better profitability.

Seasonal Cash Flow Management

The seasonal nature of landscaping means you need to plan your cash flow carefully:

Peak Season (Spring and Autumn)

Revenue is strong. Use this period to:

  • Build a cash reserve (aim for three to six months of fixed costs)
  • Set aside money for tax (30% of profit is a good starting point)
  • Invest in equipment or training
  • Pay down any business debt

Slow Season (Winter)

Revenue drops. To survive:

  • Rely on your cash reserve from peak season
  • Focus on maintenance contracts that continue year-round
  • Consider offering winter-specific services (drainage work, hardscaping, tree removal)
  • Reduce casual labour hours
  • Use the time for equipment maintenance and business planning

Cash Flow Forecasting

Create a simple cash flow forecast. For each month, estimate:

  • Expected revenue (based on signed contracts and historical patterns)
  • Fixed costs (rent, insurance, vehicle costs, loan repayments)
  • Variable costs (materials, labour for specific projects)
  • Tax obligations (BAS, income tax, super)

A tool like SortBooks can help by providing accurate historical data for your forecasts.

Equipment Management

Landscaping equipment is a major investment:

  • Ride-on mowers - $5,000 to $30,000
  • Commercial push mowers - $1,000 to $5,000
  • Excavators - $30,000 to $150,000 (or hire at $300 to $600/day)
  • Trucks and trailers - $20,000 to $100,000+
  • Hand tools and power tools - $500 to $5,000 per item

Buy vs Hire

For equipment you use frequently, ownership is usually more cost-effective. For occasional needs, hiring makes more sense. Your bookkeeping should track both owned equipment (as assets with depreciation) and hire costs (as expenses).

Depreciation

Record major equipment as assets and depreciate over their effective life. The ATO provides guidance - for example, ride-on mowers have an effective life of around 7 years. Use the instant asset write-off for eligible purchases.

Subcontractor Management

Landscapers frequently engage subcontractors for specialist work:

  • Verify their ABN before payment
  • Withhold 47% if they do not provide a valid ABN
  • Lodge a Taxable Payments Annual Report (TPAR) by 28 August each year
  • Keep records of all subcontractor payments
  • Ensure written agreements are in place

Vehicle Expenses

Landscapers are on the road constantly. Track vehicle expenses accurately:

  • Fuel - Record every fill-up
  • Registration and insurance - Annual costs
  • Servicing and repairs - Regular maintenance extends vehicle life
  • Loan repayments - If financed, track the interest and principal separately
  • Depreciation - For owned vehicles

If you use a vehicle for both business and personal purposes, track the business-use percentage using a logbook.

GST and Tax

GST - All landscaping services are subject to GST if you are registered. Materials, labour, and equipment included in your quotes should be GST-inclusive.

PAYG - If you have employees, withhold tax from wages and remit through your BAS.

Income tax - Set aside 30% of profit for tax obligations. Adjust based on your actual tax rate.

Super - 11.5% of ordinary time earnings for employees, paid quarterly.

Bookkeeping Setup

  1. Use Xero or QuickBooks with job costing (tracking categories)
  2. Set up separate income accounts for project work and maintenance
  3. Track all costs per project
  4. Automate transaction categorisation with SortBooks
  5. Reconcile bank accounts weekly
  6. Run project profitability reports after each job
  7. Create a seasonal cash flow forecast
  8. Review financials monthly

Landscaping is a rewarding business, but only if you know your numbers. Set up proper bookkeeping systems and you will have the confidence to quote accurately, manage cash flow, and grow sustainably through every season.
