Essential Financial KPIs Every Business Owner Needs to Track
Running a successful business takes more than hard work and expertise in your field, it requires a clear understanding of the numbers that drive profitability and sustainability. For business owners across New Zealand, from agriculture and earthworks to engineering and construction, knowing which financial KPIs (Key Performance Indicators) to track can make all the difference between thriving and just getting by.
At Bizdom, we work with clients across Hawke’s Bay and throughout New Zealand, helping them understand the financial health of their business and make smarter decisions for growth. Below, we’ve outlined the essential financial KPIs that every business owner should be monitoring.
1. Gross Profit Margin
Why it matters: This KPI measures the profitability of your core operations by showing how much money is left after accounting for direct costs (materials, labour, subcontractors).
Agriculture & Earthworks: Helps track efficiency in managing inputs such as feed, fertiliser, or fuel.
Construction & Engineering: Ensures project costs are under control and pricing remains competitive.
2. Net Profit Margin
Why it matters: This shows the percentage of revenue that remains as profit after all expenses, including overheads, tax, and interest.
Professional services & law firms: Critical for understanding true profitability after staff and overhead costs.
Architecture & plumbing businesses: Useful for comparing profitability across projects and clients.
3. Operating Cash Flow
Why it matters: Profit on paper means nothing without cash in the bank. Tracking cash flow ensures you can cover wages, suppliers, and reinvest in your business.
Construction & earthworks: Projects often require large upfront outlays before invoices are paid.
Agriculture: Seasonal cash flow fluctuations make monitoring vital to avoid shortfalls.
4. Accounts Receivable Turnover
Why it matters: This KPI tracks how quickly customers are paying you. A slow turnover ties up working capital and impacts your ability to invest in growth.
Engineering & professional services: Delayed payments can quickly erode profitability.
Plumbing & construction: Fast collection reduces reliance on overdrafts or borrowing.
5. Debt to Equity Ratio
Why it matters: A measure of financial leverage, showing how much of your business is funded by debt versus your own capital.
Construction & earthworks: Businesses with heavy equipment investment need to monitor debt levels carefully.
Agriculture: Helps maintain a healthy balance when managing loans for land, machinery, or livestock.
6. Work in Progress (WIP)
Why it matters: For project based industries, WIP ensures you’re accurately tracking project costs, progress, and profitability before completion.
Architecture, engineering, and construction: Prevents underbilling or overbilling and ensures profitability at each project stage.
Professional services & law firms: Keeps track of billable hours versus completed work.
7. Return on Investment (ROI)
Why it matters: Whether it’s investing in new machinery, staff training, or marketing, ROI tells you whether the return justifies the spend.
Plumbing & engineering firms: Measures the effectiveness of investing in tools, vehicles, or technology.
Agriculture: Helps assess the return from new equipment, crop varieties, or systems.
8. Breakeven Point
Why it matters: Knowing exactly how much revenue you need to cover costs helps you price services correctly and plan for sustainable growth.
Law firms & professional services: Ensures fees are set at levels that cover both staff salaries and overheads.
Construction & plumbing: Provides clarity on the minimum workload needed to remain profitable.
