How to Write a Scope of Works (with a free Australian template)

What a Scope of Works actually is

A Scope of Works (SOW) is the written list of exactly what you will do on a job, broken into sections and line items, that sits behind your price. It tells the client what is included, what is not, and what you have allowed for where the detail is not settled yet. On a bathroom it might be one page. On a full renovation it might run to ten. The format matters less than the discipline: every task written down, grouped the way the work actually happens on site, priced or allowed for, with your assumptions stated in writing.

A quote is the number. The scope is the reason the number is what it is. Hand a client a number on its own and you have invited them to shop it on price alone. Hand them a scope and you are showing them the work.

Why a clear scope wins you work

Writing the scope properly is not paperwork for the sake of it. It is the cheapest insurance you will ever write, and one of the best sales tools you have.

• You win more jobs. An itemised scope reads as professional and builds trust before you have lifted a tool. Next to a one-line lump sum, it wins.
• You get paid for everything. Every task is listed, so nothing gets done for free and every variation is easy to justify.
• You get fewer disputes. When the scope is specific, there is far less room for "I thought that was included".
• You get faster sign-off. Clients approve a scope they can actually read and understand.

The jobs that go bad are almost never the ones where the scope was too detailed.

The six parts of a scope of works

Every scope, on every job, uses the same six-part structure. Once it is muscle memory you stop forgetting things, because the structure prompts you.

• Job details. What the work is, where it is, and which job this is.
• Preliminaries. The things you do on every job that do not belong to any one trade.
• The works. The actual tasks, grouped trade by trade or area by area, in build order.
• Allowances. PC items and Provisional Sums, kept in two separate lists.
• Inclusions, exclusions and qualifications. What is in, what is out, and what you have assumed.
• Acceptance. Somewhere for both parties to sign and date.

1. Job details: get the header right

The header is the boring bit everyone rushes, and it is the bit that causes confusion six weeks later when there are three revisions floating around. Keep it short and complete:

• Job description: what the work actually is, in a line.
• Job number or ID: your own reference, so revisions can be tracked.
• Site address.
• Client name.
• Prepared by, date and revision number.

2. Preliminaries: always start here

Preliminaries are the costs of running the job that do not belong to any one trade. This is where most tradies quietly lose money, because the work is real but it never makes it onto the quote. You run the job, chase the other trades, and do the paperwork at night, and none of it was priced.

Three lines belong in every scope you write, on every job, no matter how small:

• Provide adequate Supervision for duration of works
• Allowance for all necessary administration work throughout the duration of works
• Allow to remove all construction-related rubbish and debris from site and leave all work areas clean and tidy upon completion

Then add the job-specific preliminaries: site establishment, temporary fencing, scaffold, traffic management, protection to floors and adjoining areas, temporary power, permits. If it is something you have to do before or around the trade work, it goes here.

3. The works, trade by trade

List the work in the order it actually happens on site, top to bottom. Demolition and site prep, then structure, then services rough-in, then linings, then fit-off and finishes. Working in build order is not just tidy: it is how you catch the gaps, because a missing step is obvious when the sequence is in front of you.

Give each trade its own block with its own line items, quantities where you have them, and a rate. For a bathroom that might read:

• Strip out and dispose of existing wall and floor tiles, fittings and fixtures
• Supply and install new waterproofing membrane to floor and walls, to AS 3740
• Supply and lay floor and wall tiles, 6 m2 floor and 22 m2 wall
• Install new vanity, toilet suite and shower screen

Note what a line does and does not cover while you are writing it. "Retile bathroom" leaves the argument open. "Supply and lay floor and wall tiles, 6 m2 floor and 22 m2 wall, tiles by client" closes it.

4. PC items and Provisional Sums: keep them separate

These two get mixed up constantly, and mixing them up misstates your price and your contract. They are separate classifications and clients treat them differently.

Keep them in two separate lists on the scope, each clearly labelled. Never tag a PS allowance as PC, or a PC item as PS. Get it wrong and you have under-quoted your labour, and you are having an awkward conversation about an adjustment with a client who no longer trusts your numbers.

5. Inclusions, exclusions and qualifications

Inclusions

List what is in the price so the client can see the value they are getting. All labour, plant and materials to complete the works described, unless noted otherwise. This section is doing sales work: it is the summary a client actually reads.

Exclusions

The fastest way to a dispute is leaving exclusions unsaid. If you do not say what is out, the client assumes it is in, and silence always gets read in their favour. Be specific: asbestos removal, works to areas not noted, council and authority fees, anything by others, making good to adjoining surfaces, after-hours work. If painting is not in your tiling price, write "excludes painting".

Qualifications

Your assumptions and conditions, written down. Pricing valid for 30 days. Access assumed during normal working hours. Latent conditions excluded. Quantities based on the drawings you were given, to be confirmed on site. Whether the price includes or excludes GST, stated plainly (our GST calculator handles both directions). Every one of these is a line you will be glad you wrote if the job goes sideways.

6. Acceptance: make it signable

Finish with a signature block: client signature and date, and your signature and date for and on behalf of the business. It costs you two lines and it turns a document the client "has somewhere in their email" into an agreement with a date on it.

A worked example: small kitchen refresh

Here is the structure filled in, so you can see how it reads. Figures are illustrative only, always use your own current rates.

Notice the supervision, admin and clean-up lines add $1,370 to a job most tradies would have quoted at $6,020. That is not padding. That is work you were always going to do.

How much detail is enough?

Detailed enough that the client, and anyone reviewing it after you, can see what is and is not included, without padding it out with items you will not do. A good test: if you handed the scope to another tradie in your trade, could they price the same job from it and land near your number? If yes, it is detailed enough. If they would have to ring you with questions, the gaps in the scope are exactly the questions they would ask.

Detail is not the same as length. Twelve specific line items beat three paragraphs of prose every time, because a client can tick down a list and a client cannot tick down a paragraph.

The mistakes that cost the most

• No supervision or admin in the price. Hours of unpaid coordination on every single job.
• Vague wording. "Renovate bathroom" means one thing to you and another to the client.
• Mixing PC and PS. Under-quoted labour and an adjustment conversation you did not need to have.
• No exclusions list. Work you never priced, because the quote did not rule it out.
• Pricing from memory. Whole tasks left out, found the hard way once you are on the tools.

Every one of them is fixed by using the same structure on every job instead of starting from a blank page.

Writing your scope faster

The reason most tradies do not write scopes like this is time, not knowledge. You already know what goes into the job. Typing it out properly, in order, with quantities and allowances, is an hour at the kitchen table after a ten hour day, and that is the hour where quotes quietly turn into "I will send it tomorrow".

That is the job BuildScope does. Talk through the job on site or paste your rough notes, and it writes the scope in this structure: Preliminaries first every time, the works grouped trade by trade, PC and PS kept separate, ready to check, adjust and send while the job is still fresh.
