Tradie Business Start-Up Costs: Calculate Cash Before Job One

You accept the first job. Materials need paying now, the hired access gear carries a deposit, and the customer pays later. Your tradie business start-up costs must cover that cash gap as well as the gear needed to do the work.

Start with one service you can sell. Confirm every amount. Put every payment and customer receipt on a calendar. The lowest projected cash balance tells you how much funding the launch needs.

Define the first service before calculating tradie business start-up costs

Choose a narrow piece of work you can quote, complete and invoice. Do not build the launch budget around every service you might offer later.

The first service decides which skills, tools, materials, licences and site arrangements you need. It also gives you a reason to reject purchases that can wait.

Use the trade industry pages to map the service to the type of jobs you intend to run. Then write the scope in words that could go straight onto a customer quote.

Write a sellable scope

Name the work. Name the supplied items. State what completion looks like.

Record:

• The task you will complete.
• The materials and fittings you will supply.
• Any customer-supplied items.
• The labour and trade skills required.
• Access, parking, power, water and disposal arrangements.
• Testing, commissioning or cleanup included.
• Work expressly excluded.

“Replace the named unit using the existing connection” can be inspected and costed. “General installation work” cannot.

State who repairs disturbed surfaces. State whether access equipment is included. If the existing wiring, pipework, structure or substrate must meet an assumption, write that assumption into the scope.

Inspect the likely site conditions

Walk through the work from unloading the ute or van to handing the job back. Inspect before you choose equipment and before you quote.

Look for restricted access, lined ceilings, hidden services, weak surfaces, missing isolation points and preparation work. Check where equipment can be loaded, set up, cleaned and collected.

An unknown condition is not free labour. Put it in the quote as an assumption or exclusion. If the condition changes on site, stop, describe the extra work and get the variation approved before continuing.

Defer purchases the opening service does not need

Take each planned purchase and ask one blunt question: does the defined first service need this item?

If not, move it to a later equipment list. Do not keep it in the launch figure because it might be useful one day.

This applies to tools, vehicle fit-out, stock, office gear and subscriptions. A smaller opening scope produces a cleaner startup cost checklist and leaves more cash available for work already sold.

Clear the Australian launch gates before spending

Do not commit cash until you know the planned work can be advertised and completed under the business setup you have chosen. Ask each public body only about the question it handles.

ABN, GST and BAS are tax and registration questions. A company or business name is a separate registration question. Neither answer tells you whether you hold the trade or contractor licence required for the work.

Use this launch-gate table. Record the answer you receive, the document held, the confirmed amount due and its payment date.

If you do not know which licensing body handles the work, search the activity and job location through the Australian Business Licence and Information Service (opens in a new tab). Then ask the named regulator about the exact scope. For a NSW job, for example, ask NSW Fair Trading (opens in a new tab) about trade and contractor licences or home building contracts in NSW.

Separate the 80% question from the budget

The “80% rule” is a personal services income question. It is not a rule for dividing start-up cash between tools, materials and working capital.

Use the Australian Taxation Office personal services income guidance and decision tool (opens in a new tab) for your income and contract circumstances. Keep that answer with your tax records, not in the equipment budget.

Treat ABN and GST as different questions

Earning less than the GST registration threshold does not, by itself, decide whether you are entitled to an ABN. Check ABN entitlement with the Australian Business Register (opens in a new tab) using the business activity you actually plan to carry on.

ABN entitlement and GST registration are separate tests. Ask the Australian Taxation Office (opens in a new tab) what GST and BAS treatment applies, then put any confirmed administration cost into the budget on its payment date.

Build a tradie business start-up costs worksheet

Use plain cost groups. The point is to know why cash leaves, when it leaves and whether a particular job caused it.

Do not use an average startup figure. Obtain written quotations, bills, hire terms, insurance terms and amounts confirmed by the responsible public body. Enter your own AUD amounts.

Setup and permission costs

Record payments required to establish the chosen business and clear the first work scope. That may include registration, licensing and professional setup work you have confirmed.

Use specific descriptions. “Business setup” hides the payment. “Business name registration due before advertising” tells you what the money is for.

Insurance, administration and customer documents

Enter insurance payments and administration due before the first customer payment. Record the amount that actually falls due, not the total value of an agreement unless it must all be paid at once.

Include the customer documents needed for the first service. The quote, acceptance record, variation process and invoice must be ready before work starts. Ask the licensing regulator whether the planned residential work raises a home building contract question in that state or territory.

Tools, safety gear, test equipment and transport

List only the kit needed to transport, perform and test the opening service. Include required ute or van storage and restraints where the work depends on them.

Inspect owned equipment. A tester that lacks a required check, accessory or consumable is not job-ready. Neither is a tool with a failed battery or equipment that cannot be transported safely to site.

Add planned equipment servicing that falls due before the first job. Keep later servicing dates out of the immediate cash requirement, but retain them in the forward overhead calendar.

Direct costs caused by the first jobs

Attach labour, materials, hire, delivery, disposal and subcontract costs to the job that causes them. These are direct job costs.

Materials may need paying before customer money becomes usable. That creates two records. The job record shows what the work costs. The cash calendar shows when the business must fund it.

Overhead due during the launch

Record bills that support the business rather than one named job. Use their real payment dates.

Keep overhead separate from direct labour and materials. A fitting installed at a property belongs against that job. A business bill supporting several jobs belongs in overhead. The separation makes later cost tracking useful.

Use this copy-ready worksheet:

First service: [defined service]
Planned first-job date: [date]
Expected customer cash-available date: [date]

Cost item: [item or payment]
Reason it is needed: [reason]
Cost group: [Setup and permission / Insurance and administration / Equipment and transport / Direct job cost / Overhead]
Supplier, payee or public body: [name]
Confirmed amount in AUD: [your amount]
Payment date: [date]
Refundable amount, if any: [your amount]
Expected refund date, if any: [date]
Evidence held: [quotation / bill / hire terms / official confirmation / receipt]
Status: [not committed / ordered / paid]
Linked job or general overhead: [job reference or general]

Calculate equipment costs when the gear is job-ready

The shelf price or hire charge is not the full equipment figure. Calculate the cash needed to get the item to site, set it up, use it, check the result, clean it and return it.

Use these separate calculations:

Equipment cost = purchase or hire charge + attachments + transport + setup + checks + first-use consumables

Cash required before customer payment = equipment payments due + refundable hire deposit

Walk the equipment through the actual job. Check loading, delivery, attachments, batteries, leads, blades, fixings, calibration or other required checks, cleaning and collection.

Record hire deposits separately

A refundable deposit is not a final equipment cost. It still removes usable cash while the supplier holds it.

Enter the deposit as its own cash outflow. Add the expected return date as a separate receipt. Do not reduce the hire expense by the deposit or assume the refund will be available before its written return date.

Choose whether to use, buy, hire or subcontract

Make the decision item by item.

• Use existing equipment when it suits the scope, is available and is ready for work.
• Buy when ownership is needed for the opening service and the cash plan can carry it.
• Hire when the booked period, delivery, attachments, collection, deposit and return terms are confirmed.
• Subcontract when another qualified business should provide the skill, controlled work or specialised equipment.
• Defer the item when the opening service does not need it.

For subcontracted work, write the exact task, supplied items, completion point and payment date. A verbal allowance is not enough for the quote or cash calendar.

Price the first job without hiding launch purchases

Build the quote from the work being sold. Start with direct labour and materials. Add job-specific hire, delivery, disposal and subcontract costs. Allocate overhead using your chosen method. Then add markup.

Keep one-off setup spending visible in the launch budget. Do not bury a full vehicle fit-out, registration payment or future-service tool inside the material allowance for the first customer.

Use a compact pricing framework:

Direct job cost = direct labour cost + materials + job-specific hire, delivery, disposal and subcontract costs

Cost before markup = direct job cost + overhead allocation

Quoted price before GST = cost before markup + markup amount

Markup is what you add to cost to form a price. Margin is profit as a share of the selling price. Use the markup versus margin guide before issuing the first quote.

A profitable quote and a funded job answer different questions. The quote tests job profitability. The dated cash calendar tests whether the bank balance can carry each payment until customer cash arrives.

Test the quote with the Oak Street worked example

Oak Street is the house electrical example. Every figure below is in sample currency units. It is not an Australian rate card.

R. Chen received Estimate E-1847 for a bathroom exhaust fan, 150mm and ducted through the roof, and four LED downlights, with a range of 900–1,400. Quote Q-1847 then set the agreed scope and total at 1,105.

The measured job cost against the original quote was 850. Profit against that quote was:

1,105 − 850 = 255

Margin was:

255 ÷ 1,105 ≈ 23%

Markup was:

255 ÷ 850 = 30%

The ceiling was lined and the quote excluded chasing. Extra cable and chasing were approved on site as a 160 variation. Invoice INV-1847 therefore totalled 1,265.

Do not calculate profit from the 1,265 invoice. The costs caused by the variation are not supplied. Combining the invoice total with the original job cost would produce a false profit figure.

Electrical businesses can use the Australian electrician variation process to document changed renovation work before continuing on site.

The invoice total also says nothing about the available bank balance. Supplier payments may fall due before R. Chen’s payment becomes usable. That timing belongs in the working capital test.

Calculate working capital from the lowest cash balance

Working capital carries the business between paying for work and receiving customer cash. Profit does not tell you whether money is available on a particular day.

Build a dated cash calendar. Start with the launch cash available. Enter every confirmed outflow on the date it must be paid. Enter customer money only on the date you reasonably expect it to become usable.

Include:

• Setup and registration payments.
• Insurance and administration bills.
• Equipment purchases and hire charges.
• Refundable deposits as separate outflows.
• Materials, delivery and disposal.
• Labour and subcontract payments.
• Overhead due before customer payment.
• Customer receipts on their expected usable dates.
• Deposit refunds on their written expected return dates.

Calculate the projected balance after each entry. The lowest projected balance sets the funding test. If the balance falls below zero, the launch needs more available cash, different payment timing or a smaller opening commitment.

Do not move customer cash to an earlier date just to make the calendar work. Test the written payment terms. Check when card, transfer or finance proceeds become usable. Check supplier terms and hire deposit returns the same way.

This is where tradie business start-up costs differ from a list of expenses. A cost list tells you what the business buys. The cash calendar tells you whether the business can make each payment when due.

Open the job record before buying materials

Create the first job record as soon as the scope is defined. Add the estimate or quote, cost buckets, supplier documents, expected payment dates and customer payment terms.

Record actual vs estimated cost as labour records and bills arrive. Keep the original allowance visible. If materials, hours or equipment use differ, write down why instead of replacing the estimate.

After the work is complete, use the job-costing close-out process to test labour, materials, overhead and job profitability before pricing the next job.

Treat job management software for tradies as one line in your tradie business start-up costs only when the opening process needs it. Yes Foreman can keep the quote, approved variation, invoice and costs against the same job, so the paperwork follows what happened on site.
