Marking Up Supply & Install Without Losing the Job
Protecting your margin, winning more work, and the supplier relationship behind it
Every installer knows the squeeze: price the job too high and the customer goes with the cheaper quote; price it too low and you're working for nothing once the truck, the time and the callbacks are counted. Getting your supply-and-install markup right is the difference between a busy year and a profitable one. Here's how to protect your margin without pricing yourself out — plus the supplier habits that quietly make it easier.
1. Know your true cost — not just the unit price
The most common margin killer is pricing off the equipment cost alone. The unit is only part of the job. Before you mark anything up, account for the lot: the system, consumables (copper, brackets, drain, fittings), your labour and your offsider's, travel, vehicle running costs, insurance, and a buffer for the unexpected. Build a simple job-cost template so nothing slips through — the small stuff is where margin leaks.
2. Mark up on margin, not markup
There's a trap in the maths. Adding "30% markup" to your cost is not the same as making a 30% margin. A unit that costs you $1,000 with 30% markup sells at $1,300 — but that's only a 23% margin. To actually keep 30% of the sale price, you'd price it at about $1,430. Decide the margin you need to run a healthy business, then work backwards to the price. Pricing on markup alone is why a lot of "busy" installers stay broke.
Quick example
Job cost $3,000 (unit + consumables + labour). For a 35% margin, divide by 0.65 → price the job at about $4,615. Marking up 35% would only get you $4,050 and a 26% margin — a $565 difference on one job.
3. Sell value, not the lowest number
When a customer pushes on price, the instinct is to drop it. Resist. You're not selling a box — you're selling a clean, compliant, warranty-backed install that won't leak, trip or fail in two summers. Spell out what's included: quality brand, correct sizing, tidy workmanship, warranty, and the fact you'll actually answer the phone if something goes wrong. The cheap quote rarely includes all that, and customers respect an installer who explains the difference instead of caving.
4. Use VEU upgrades to add value (and bigger jobs)
In Victoria, the Victorian Energy Upgrades (VEU) program is one of the easiest ways to turn a price objection into a bigger, better job. Replacing an old gas ducted heater with an efficient reverse cycle system can attract a sizeable discount for the customer — up to around $5,530 off for the larger ducted upgrades — which makes a premium system suddenly affordable to them, while you install a bigger job.
A few things to know: the discount can only be applied by an accredited provider, so you either need to be partnered with one or work alongside one. There are no "free" upgrades — the customer must contribute at least $200 — and any product installed under VEU now needs a five-year warranty. Used honestly, it's a genuine selling tool: instead of dropping your price, you point the customer to a government-backed discount that lifts the whole job. Always confirm current eligibility and rebate values on the official VEU site before quoting.
Get ahead of the 2027 rental rule. From 1 March 2027, Victorian rental properties will need efficient electric cooling in the main living area. That's a wave of upgrade work heading for installers — landlords will be looking for compliant systems and someone to fit them. Lining up your supply and pricing now puts you in front of that demand instead of scrambling for stock when it hits.
5. The supplier relationship that protects your margin
Here's the part installers underrate: a good supplier is part of your margin. Being stuck mid-job waiting on a part, or paying retail because you couldn't get trade stock in time, eats straight into profit. The fix is a reliable wholesale supplier who holds stock, prices sharp for the trade, and gets it to you fast.
- Open a trade account so you're getting genuine wholesale pricing, not retail — that gap is your margin.
- Use same-day dispatch on stocked items so a missing fitting doesn't cost you a day on site.
- Build a relationship with a supplier who knows your business, so you can ring up and get the right part fast instead of guessing.
- Keep your van stocked with the consumables you burn through — copper, brackets, drain, condensate pumps — so small items never stall a job.
