The Job Costs You Money Before The Client Pays
You win the job.
Good news. Then the spending starts.
Materials ordered. A deposit to the supplier. The crew on site. A subbie for the specialist work. Equipment hire. Fuel.
All of it goes out before the first invoice does.
The client pays at the end, or at the milestones, on their terms.
In between, your business is paying for their job.
Most owners know this. Few know exactly how much it is, job by job.
Every job is a short loan from your business to your client. You should know how big it is.
Where The Money Goes Before The Invoice
In trades and construction, the costs land early and the money lands late.
Here is how it usually runs:
Stage of the job | What leaves the business |
Quoting and winning | Time on site visits, plans and pricing |
Starting | Materials ordered, supplier deposits, equipment hire |
Underway | Wages, super, subcontractors, fuel, more materials |
Finishing | Final materials, clean-up, small fixes |
Invoiced | Nothing new, but you are now waiting for the client's terms |
By the time the invoice goes out, most of the cost has already been paid.
And the clock on the payment terms has only just started.
A Plain Example
Here is a plain example. It is an example only, not a benchmark.
Say a job is quoted at $40,000.
In week one, $10,000 of materials goes out. Over the next three weeks, $14,000 of wages and subcontractors goes out.
The invoice goes out at the end of week four, on 30-day terms.
If the client pays on time, the money arrives around week eight or nine.
For close to two months, your business has carried $24,000 of someone else's job.
Run three or four of those at once, and the numbers get serious.
The job can be profitable and still squeeze the business while it runs.
A job can make money on paper and still drain the account while you are doing it.
What Good Job Costing Looks Like
Job costing just means tracking every cost against the job it belongs to.
It is not complicated. It is consistent.
1. Give every job its own code
Every quote that becomes a job gets a job number in your accounting software.
Without that, the costs all blur together.
2. Code costs as they happen
Materials, subbies, hire and labour hours go against the job when they are entered, not months later.
A cost coded at the time is accurate. A cost coded at year end is a guess.
3. Compare quote to actual while the job is running
Halfway through is when you can still do something about it.
A variation to raise. A materials order to check. A conversation with the client.
4. Watch the timing, not just the margin
Know when the big costs will land, and when the money is likely to come in.
Where your contracts allow, deposits and progress claims can keep money moving while the work is underway.
5. Use what you learn in the next quote
The jobs that ran over tell you where your quotes are light.
That is the most useful information in the business, and it is already sitting in your books.
There is no job costing template on our Free Tools page, because the useful version is built around your own jobs and your own software. That is something we set up with you.
Who Keeps The Job Numbers?
In most Australian businesses like yours, someone in the office is already entering the bills and the timesheets.
They are the right person to code costs to jobs.
They just need to be shown how, and given a simple routine to follow.
→ We train your office person to set up jobs and code costs to them as they go.
→ We review the books, look after the lodgements, and go through job results with you.
→ You see which jobs make money, which ones drain it, and how much you are carrying at any time.
Because we are already in your numbers for the normal compliance work, the job conversation happens as part of it.
Which types of jobs to chase. Which ones to reprice. Where a deposit would help.
It is not a separate project. It comes from keeping the books right.
A Quick Self-Check
Take a minute and answer these honestly.
Question | Yes / No |
Does every job have its own code in your accounting software? | ☐ |
Are materials and subbies coded to jobs when the bill is entered? | ☐ |
Do you compare quote to actual before the job finishes? | ☐ |
Do you know how much cash is tied up in jobs right now? | ☐ |
Could you name your three most and least profitable jobs this year? | ☐ |
If several answers are "No", you are not doing anything wrong.
The information just is not being captured in a way you can use.
That is fixable.
Final Thought
You will always pay for the job before the client pays you.
That is how the work runs.
What you can change is how clearly you see it.
When every cost sits against the right job, you can quote with confidence.
You can see the squeeze coming.
You can ask for a deposit without second-guessing it.
You'll know what to do next.
