7 Quoting Mistakes That Cost Tradies Thousands Every Year

Most tradies are skilled at their trade and learning the business side as they go. These seven quoting habits are the ones that quietly drain profit, and each one has a simple fix you can apply to your next quote.

1. Charging for tool-time only

The average sparky, plumber, or chippy spends 25 to 40 percent of their work week off the tools: quoting, driving, answering calls, ordering materials, chasing payments, doing paperwork. If you charge only for hours holding a drill or a pipe wrench, you are working a quarter of your week for free.

What profitable tradies do: They calculate a true hourly rate that covers every working hour, including admin. The formula is simple:

(Target annual income + all overheads) ÷ total billable hours per year = your real hourly rate

If your target income is $150K, overheads run $60K, and you have 1,600 billable hours a year, your true rate is $131/hr. Many tradies discover their "real" rate is 30 to 50 percent higher than what they have been charging.

2. Leaving overheads out of the quote

Materials plus labour is a tempting shortcut, but it misses the costs that keep your business running: vehicle lease or rego, insurance, tools and equipment, phone, software, accountant fees, training, workwear, fuel. These overhead costs exist whether you quote them or absorb them. The difference is whether your customer covers them or your family does.

What profitable tradies do: They add a clear overhead margin (typically 15 to 25 percent) on top of direct costs. Some build it into their hourly rate; others add it as a line on the quote ("Business costs"). Either method works, as long as overheads show up in the price.

3. Quoting from stale prices

Copper pipe, timber, plasterboard, cabling, concrete: material costs shift every quarter. Supplier price lists update in January and July, and fuel surcharges move monthly. If you are quoting from memory or from a price list you built two years ago, you are quietly absorbing every increase.

What profitable tradies do: They update their pricing at least quarterly. They keep a master list of their common materials and labour items (in Xero, a spreadsheet, or their quoting app), review it against their latest supplier invoices each quarter, and adjust. Five minutes of maintenance saves thousands over a year.

Tip: Set a calendar reminder for the first Monday of January, April, July, and October. Open your price list, scan your last 10 supplier invoices, and update any items that have moved.

4. Giving verbal quotes under pressure

You are standing in the customer's kitchen. They ask "roughly how much?" and your brain reaches for a number. That number is almost always low: you want the job, you want to seem competitive, and you are estimating without your price list in front of you. Later, you work out the real cost and realise you are locked into a figure $800 below where you should be.

What profitable tradies do: They capture the scope on site (a photo, a voice note, a few dot points) and send a written quote within 24 hours. The written quote protects both parties: the customer gets a clear breakdown, and the tradie gets time to price accurately from real data.

If the customer pushes for a ballpark, a useful phrase is: "I'll have an accurate quote in your inbox by tomorrow morning. It'll have a full breakdown so you can see exactly where the money goes." Most homeowners respect that.

5. Treating "break-even" as the price

Some tradies price a job to cover costs and call whatever is left "profit." That approach works until a job runs over, a warranty claim comes in, or materials arrive damaged. Profit is planned, the same way materials are planned. It is a deliberate margin built into the quote, typically 10 to 20 percent on top of all costs (labour, materials, overheads).

What profitable tradies do: They decide on a target net margin (say 15 percent) and add it to the quote as a non-negotiable. When a customer negotiates, they adjust scope (remove a line item, simplify a specification) rather than shaving margin. The margin is what funds your next van, your apprentice's wage, and the week off at Christmas.

6. Quoting slow and following up slower

The tradie who sends a quote within 24 hours wins the job more often than the one who takes a week. Homeowners call two or three tradies for quotes, and the first clear, professional quote that arrives sets the anchor. If yours shows up four days later, the customer has already mentally committed to someone else.

What profitable tradies do: They aim to send the quote the same day they visit, or by next morning at the latest. Speed signals professionalism and reliability. The quote itself can be simple: a clear description of work, itemised pricing, and a valid-for date (14 or 30 days). It does not need to be a 10-page document.

Following up matters too. A short text or email 48 hours after sending ("Just checking you received the quote, happy to answer any questions") converts fence-sitters. Research from the trades sector consistently shows that one follow-up doubles acceptance rates.

7. Pricing from gut feel instead of a system

Every quote from memory is a gamble. Some days you quote high because you are busy and half-hoping they say no. Other days you quote low because you need cash flow. The result: inconsistent margins, unpredictable income, and the nagging sense that you left money on the table (or bought yourself a job at cost).

What profitable tradies do: They quote from a system. That might be a spreadsheet, an app, or a quoting tool. The important part is that it pulls from a maintained price list (materials at current supplier cost, labour at your real hourly rate, overheads factored in). When you quote from a system, every quote is profitable by design. You can still adjust for competition, complexity, or access, but you start from a position of knowing your numbers rather than hoping they work out.

Quote from your price list in 30 seconds

The short version

  1. Charge for all your hours, including the ones off the tools.
  2. Include overheads in every quote (15 to 25 percent).
  3. Update your prices quarterly to keep pace with supplier costs.
  4. Send written quotes, especially when pressured for a verbal number.
  5. Build profit into the quote deliberately (10 to 20 percent net margin).
  6. Quote fast (same day or next morning) and follow up once.
  7. Quote from a system, not from gut feel.

Get these seven habits right and your margins improve with every job, without needing to win more work or raise your rates dramatically.

Frequently asked questions

What is the most common quoting mistake tradies make?

The most common mistake is undervaluing your own time. Many tradies price labour based only on hours holding a tool, ignoring the real cost of quoting, travel, planning, site inspections, phone calls, and admin. Profitable tradies calculate their true hourly cost (all hours worked divided into target annual income plus overheads) and use that number in every quote.

How much do quoting mistakes cost a tradie per year?

A tradie who underquotes by just 10% on a $5,000 job loses $500. At two jobs per week, that compounds to $52,000 per year in lost profit. The most profitable operators review their quotes against actual job costs quarterly and adjust their rates and estimates to stay ahead of rising material and labour costs.

How can I stop underquoting jobs?

Three practical steps: (1) Calculate your true hourly rate including all overheads. (2) Build a price list with real supplier costs updated quarterly. (3) Use a quoting system that pulls from your actual prices rather than relying on memory or rough estimates. FlowSpec lets you speak the job on site and drafts the quote from your Xero price list in about 30 seconds.

Should tradies give verbal quotes on site?

Verbal quotes create two risks: you underestimate under pressure, and the customer remembers a different number than you quoted. Profitable tradies capture the scope on site (a voice note works well) and send a written quote within 24 hours. The written quote protects both parties and lets you price accurately from your cost data rather than from gut feel.

How often should tradies update their pricing?

Review your price list at least quarterly. Materials costs shift with supplier pricing cycles, and labour costs rise with award increases (usually July each year in Australia). Tradies who update pricing once a year often discover they have been absorbing 5 to 15 percent in cost increases without realising.
