Most tradies put fuel, materials, and tool purchases on a personal Visa and earn roughly nothing.
The average solo tradie spends somewhere between $30,000 and $60,000 a year on business expenses — fuel, materials, consumables, subcontractors, equipment. In practice, a flat 2% cash-back card on $40,000 of annual spend returns $800 in cash. Add a supplier-specific rewards card for your main trade account and that number climbs to $1,200–$1,800 a year. That's a new impact driver. A week of accommodation on a job away from home. Real money sitting in a program you haven't signed up for yet.
The Two-Card Stack
You don't need to overcomplicate this.
Card one is a dedicated business Visa or Mastercard with a flat 2% cash-back rate. No rotating categories. No points-to-miles conversion math. Cash. This catches everything — fuel, hardware, subcontractor invoices you pay on card.
Card two is your supplier's own trade account or co-branded card. Most major hardware chains and trade wholesalers run programs that pay 3–5% back in store credit on purchases made through their account. If you're spending $15,000 a year at one supplier — which is not unusual for a plumber or sparky — that's $450–$750 in credit you're currently ignoring.
Run both. Use the supplier card at that specific merchant. Use the cash-back card everywhere else.
Why the Personal Card Is a Tax Problem Too
Here's the thing most people miss: mixing business and personal spend on one card isn't just leaving rewards on the table. It's also making your bookkeeper's life harder, which means you pay them more, or you pay an accountant to untangle it at tax time.
When the ATO or IRS comes asking about expense claims, a personal card with 400 mixed transactions is a problem. A dedicated business card with clean categorized spend is not.
The rewards are the obvious win. The clean records are the silent one.
What Actually Stops People From Doing This
The application takes 20 minutes.
That's genuinely the barrier. Not complexity. Not eligibility. The tab has been sitting there for six months because 20 minutes never felt urgent enough. Meanwhile, $1,500 walked out the door.
Business credit cards for sole traders exist specifically for people in your situation. Most have no annual fee or a fee well below what you'll earn back. You don't need a company structure. You don't need an accountant's sign-off. You need an ABN, some basic income history, and twenty minutes.
The One Rule That Keeps This From Backfiring
Pay the full balance every month.
This entire strategy falls apart the second you carry a balance. A 20% interest rate on $3,000 of revolving debt costs $600 a year — which is more than the rewards you're earning. If cash flow is tight enough that you can't clear the card monthly, sort that first. The rewards are a bonus on money you were already spending, not a reason to spend more.
If you can pay it in full: run everything through it, collect the cash, move on.
The Real Number
In practice, a tradie doing $40k in annual card-eligible spend, using a 2% cash-back card plus a supplier account with a 4% return on $12,000 of that spend, earns around $1,280 a year.
That's not a rounding error. That's a month of a tool finance payment. That's two tires on the van. That's the kind of money that shows up quietly every year because you did one thing right eighteen months ago.
VettedCalls exists to stop you losing revenue at the front end. This issue is about not leaking it quietly out the back.
This week's move
Pull up last month's bank statement, total your business-related spend, and apply for one no-annual-fee 2% cash-back business card before you close the laptop today.
Forward this
If another tradie you know is still losing leads to voicemail, send them VettedCalls.
