If you're a builder, electrician, plumber or landscaper working between Mornington, Rosebud and Hastings, you've probably noticed the same thing every trade business owner on the Peninsula is dealing with right now: costs keep climbing, but your quoted rates haven't kept up. Timber, copper, fuel, insurance premiums and the Superannuation Guarantee rate have all moved in the last two years — and if your pricing model hasn't moved with them, you're quietly funding your customers' jobs out of your own margin.

Why Cost-Plus Pricing Is Failing Peninsula Trades

Most trades still price the old way: take last quarter's material cost, add labour, add a flat margin, done. The problem is that "last quarter's cost" is often six or twelve months old by the time you're quoting a job that starts in another two months. In a rising-cost environment, that lag is where your profit disappears.

  • Material costs can shift 5–15% between quoting and delivery on longer jobs.
  • Fuel and vehicle running costs hit every job differently depending on how far you're travelling around the Peninsula — Sorrento to Baxter is a very different cost than a local Mornington job.
  • Super Guarantee increased to 12% from 1 July 2025 under the Superannuation Guarantee (Administration) Act 1992 — if your labour rate wasn't recalculated, you absorbed that increase.

Building Your True Cost Base

Before you can price properly, you need an accurate number for what an hour of labour actually costs your business — not just the wage you pay. Your true labour cost includes:

  • Base wage or subcontractor rate
  • Superannuation Guarantee contributions (12% from July 2025)
  • WorkCover premiums (Victoria-specific rates apply)
  • Annual leave and personal leave loading for employees
  • Tool and PPE replacement costs
  • Vehicle depreciation and running costs

Once you have that real hourly cost, add your material markup separately — don't blend the two, or you'll never know which part of a job is actually profitable.

Not sure what your real hourly cost is?

We build true labour and job costing models inside Xero for Peninsula trades, so every quote reflects what the job actually costs — not last year's numbers.

Building a Pricing Buffer Into Every Quote

Fixed-price quotes are risky in a rising-cost market unless you build in protection. Two practical approaches:

  • Price validity windows — state your quote is valid for 14–30 days only, after which materials are re-priced at cost.
  • Variable cost clauses — disclose in your terms that material price movements beyond a stated percentage (e.g. 5%) will be passed through. This must be agreed before the job starts to comply with Australian Consumer Law — you can't add undisclosed charges after a customer accepts a fixed quote.

Both approaches protect your margin without ambushing the client with surprise invoices, which is what actually damages trust and repeat business on the Peninsula's tight-knit trade networks.

Value-Based Pricing vs Hourly Rates

Hourly rates punish efficiency — the faster and better you get at your trade, the less you earn per job. Value-based pricing (fixed project pricing based on the outcome, not the hours) rewards experience and lets you capture the value of getting a job done properly the first time. For renovation, deck-building and larger install jobs common across Mount Eliza, Mornington and Somerville, moving even part of your work to fixed project pricing — priced from accurate job costing data — protects you from cost blowouts eating your margin.

Using Xero Job Costing to Price With Confidence

Xero's job tracking and project features let you compare quoted cost against actual cost on every job, in real time. This is the single biggest lever most trade businesses aren't using:

  • Tag every expense and timesheet entry to a job
  • Run a job profitability report at completion — not six months later at tax time
  • Use actuals from your last 10–20 jobs to reset your quoting rates quarterly

Without this data, pricing decisions are guesswork. With it, you're pricing off evidence — which is exactly what a Registered BAS Agent can help you set up and interpret from your Xero file.

Reviewing Prices Quarterly, Not Annually

Annual price reviews were fine when inflation was steady at 2–3%. They don't work when material and labour costs are moving every quarter. Build a simple habit:

  • Every quarter, pull your job costing report from Xero
  • Check actual material and labour cost against your quoted rate
  • Adjust your standard rate card before the next quoting cycle, not after a string of unprofitable jobs

When to Say No to a Job

Not every job is worth taking, especially when a customer pushes back hard on price. If a job requires you to discount below your true cost floor (labour + super + WorkCover + materials + minimum margin), walking away protects the business more than winning the work does. Cash flow strain from underpriced jobs is one of the most common reasons trade businesses on the Peninsula end up behind on BAS and super obligations — which then triggers ATO attention under the ATO's small business benchmarking program.

Rising costs aren't going away, but underpriced jobs are optional. Start by working out your true hourly cost, build a small buffer into every quote, and use your Xero data to review pricing every quarter instead of once a year. That single habit change is often the difference between a trade business that's stressed every BAS quarter and one that's genuinely in control of its margin.
