Hidden Risk
📋
Your old quotes are costing you money right now
Any quote sent more than 3 weeks ago is now underpriced. Major Tier 1 contractors have cut their quote validity to just 15 days. Still running 30–90 day fixed prices? Every material price rise between signing and buying is coming out of your pocket.

What To Do

What to do & when

In order of urgency. Just work through the list.

1
🔴 Do this today
Fix your quotes — right now
  • Shorten all quote validity to 7–14 days maximum
  • Call back any open quotes older than 3 weeks — reprice them
  • Add to every new quote: "Prices valid 14 days. Materials subject to supplier adjustment."
  • Ring your 2–3 main suppliers — get current price lists in writing
2
🔴 Do this today
Recalculate your diesel cost per job
  • Diesel is $3.25/L+ — your fuel line is almost certainly undercosted
  • Update your quoting template with the real number
  • Add a visible "Fuel & freight levy" line to all new quotes
3
🟠 This week
Pre-order materials for confirmed jobs
  • Signed contract in hand? Buy the materials today at today's prices
  • PVC, copper and PE pipes especially — next price move hits 17 April
  • Holding stock for 2–3 weeks beats paying 28–36% more next month
4
🟠 This week
Tighten up your cash flow
  • Move to 30–40% upfront deposits on all new jobs — you need cash to pre-buy materials
  • Chase outstanding invoices — tighten debtors to 7 days
  • Review your 5 largest active jobs — still profitable at current material costs?
5
🟠 This month
Talk to your clients early — don't go quiet
  • Clients have seen the news — most will understand a straight conversation
  • Email or call before a quote expires — explain the market, offer an update
  • Tradies who communicate early maintain trust. Tradies who absorb costs quietly until they can't are the next insolvency statistic
6
🟠 This month
Find substitute materials now
  • Talk to suppliers about alternatives before shortages force your hand
  • Consider pooling orders with another local tradie for better pricing and priority access
7
⚫ Next 90 days
Shift larger jobs to cost-plus pricing
  • Fixed-price lump sum is too risky for jobs over $30K right now
  • Move to cost-plus with an agreed margin — explain this is now industry standard
  • Build a 15–20% materials contingency into all new job cost templates
8
⚫ Next 90 days
Plan for the June cliff
  • The fuel excise cut expires in June — prices could spike again
  • Any job starting after June needs an escalation clause and a fuel buffer baked in
  • Watch the RBA — rising inflation could lift interest rates, slowing client demand

The tradies who come through this will be the ones who repriced fast, communicated early, and protected their cash flow. The ones who absorb costs silently and hope it blows over are the next insolvency statistic. Take action today.
