You've got plenty of work, your customers are happy, and your profit margins look good on paper. So why can't you pay your suppliers on time? The answer is likely cash flow. Many profitable businesses struggle because they don't manage their cash flow effectively. This guide will help you understand and master cash flow in your electrical business.

What is Cash Flow?

Cash flow is the movement of money in and out of your business. Unlike profit (which is an accounting concept), cash flow is about the actual money available to pay bills and keep operating.

The Simple Formula:

Cash In (from customers) - Cash Out (expenses) = Net Cash Flow

Why Electricians Struggle with Cash Flow

Payment delays: Customers take weeks or months to pay invoices
Large material purchases: You pay for materials upfront but get paid later
Seasonal fluctuations: Busy periods followed by quiet times
Growth costs: Expanding requires investment before returns
Tax payments: Quarterly or annual tax bills

Warning Signs of Cash Flow Problems

⚠You're regularly late paying suppliers
⚠You can't take advantage of early payment discounts
⚠You're relying on credit cards or overdrafts
⚠You struggle to pay yourself
⚠You can't afford to buy materials for new jobs
⚠You're constantly chasing late payments

Strategies to Improve Cash Flow

1. Get Paid Faster

Invoice immediately: Don't wait until the end of the week or month
Set clear terms: 7 or 14 days is standard for trade work
Take deposits: 50% upfront for larger jobs
Progress payments: For long jobs, invoice at milestones
Offer early payment discounts: 2% for payment within 7 days
Charge late fees: Make it clear in your terms

2. Manage Your Spending

Negotiate supplier terms: Ask for 30-day payment terms
Buy only what you need: Don't overstock materials
Time large purchases: Buy equipment when cash is healthy
Use trade accounts: Get the best prices and payment terms

3. Build a Cash Reserve

Aim to have 2-3 months of operating expenses in reserve. This buffer helps you through:

Quiet periods
Unexpected expenses
Delayed payments from major customers
Equipment breakdowns

4. Set Aside Tax Money

One of the biggest cash flow shocks is a tax bill you haven't prepared for. Set aside money for tax with every payment you receive:

25-30% for income tax (varies by structure and profit)
1/11th of sales for GST (Australia) or track GST separately

Cash Flow Forecasting

A cash flow forecast helps you predict future cash positions and plan accordingly. Create a simple spreadsheet showing:

Expected income (based on work booked and payment terms)
Expected expenses (regular bills, payroll, materials)
One-off payments (tax, insurance renewals)

Update this weekly and look ahead at least 3 months.

When Cash Flow is Tight

If you're experiencing a cash crunch:

Contact creditors: Explain the situation and negotiate payment plans
Chase overdue invoices: Prioritise collection efforts
Consider invoice financing: Get advances on unpaid invoices
Reduce spending: Postpone non-essential purchases
Take on quick jobs: Small, fast-paying work can help bridge gaps

The Difference Between Profit and Cash Flow

Many electricians don't understand this critical distinction:

Example:

You complete a $10,000 job in June
Materials cost $3,000
Labour cost $2,000
Profit: $5,000 (looks great!)

But if the customer pays in 60 days (August), and you paid for materials immediately:

June: You're out $5,000 (materials + labour paid, no money in yet)
August: Money finally arrives

This is why profitable businesses can still run out of cash.
