The work order says “water leak”. It does not say whether the plumber should inspect it, make it safe or complete the repair. That is how plumber strata work starts without a usable scope.
Fix the authority before you send a tradie. Record who requested the job, who controls spending, what the approval limit covers and where the work must stop.
Build an authority map before accepting plumber strata work
A strata job can involve a strata manager, strata committee, building manager, occupant, lot owner and accounts team. They may all discuss the fault. They do not all have authority to approve spending.
Treat each role as a separate field in the job record:
- Client: the party engaging your plumbing business.
- Payer: the party named for invoicing.
- Spending approver: the person allowed to approve the quoted work and variations.
- Site contact: the person arranging entry, parking or keys.
- Occupant: the person using the affected lot.
- Accounts contact: the person who needs the invoice and work-order reference.
Get names, phone numbers and email addresses. Do not write “committee” or “building contact” where a named approver should be.
The person opening the door is not automatically the person who can spend the client’s money. If the occupant asks your tradie to replace another tap while on site, record the request but do not start. Send it to the named approver.
Ask who can approve urgent and permanent work
Ask the client what authority applies during business hours and after hours. Separate authority to inspect, make the area safe and complete a permanent repair.
An urgent instruction might allow isolation or another temporary measure without authorising replacement pipework. Write down the allowed action and the approval path for anything more.
If the strata manager gives approval by phone, ask for a written reference before continuing. An email or approved variation linked to the work order gives accounts something to match later. A tradie’s note saying “manager approved” is weak if it does not name the manager, time, scope and approved amount.
Send responsibility questions back to the client
Document whether the fault appears to be in a lot, a service area or common property. Record the exact location, affected fixture or service, and what you found.
Do not decide who must pay. That is an instruction for the authorised strata contact to give. Your job is to describe the plumbing facts clearly enough for that person to make the call.
Before accepting work outside your usual scope, check which licence class covers it. For a job in New South Wales, ask NSW Fair Trading (opens in a new tab) about plumbing and contractor licence scope. For work elsewhere, use the equivalent state or territory licensing regulator and write down the answer.
Turn plumbing work orders into a usable scope
Good plumbing work orders tell the tradie where to go, what has been requested and who can approve the next decision. A reference number by itself is not a scope.
Require these details before booking:
- Property address and postcode.
- Lot, unit, plant room or common-area location.
- Work-order reference.
- Reported fault and when it occurs.
- Requested attendance outcome.
- Site and occupant contacts.
- Access instructions and attendance restrictions.
- Approved scope and exclusions.
- Plumber approval limits and the named approver.
- Required photos, reports, readings or completion documents.
- Invoice recipient and required invoice reference.
If fields are missing, send the order back for clarification. Guessing at dispatch creates arguments at invoicing.
A reusable work order template can give the client the fields you need instead of relying on a short email.
Separate inspection, make-safe work and permanent repair
Use separate scope lines for each stage:
- Inspection locates and records the fault.
- Diagnosis identifies the affected service and likely cause.
- Make-safe work controls the immediate risk or damage.
- Permanent repair restores the agreed service.
- Reinstatement closes walls, ceilings, finishes or access points where included.
The work order may authorise some stages and not others. Write that distinction into the job brief.
For example, “attend water leak” is not enough. Replace it with wording that says whether the visit covers diagnosis only, temporary isolation, a repair within a supplied limit or a report for further approval.
Write inclusions, exclusions and deliverables before costing
State the included labour, materials, access and testing. Then state what is excluded.
Common scope boundaries include concealed pipework, destructive access, specialist locating, after-hours attendance, reinstatement, traffic control and work in another lot. Include a boundary only when it matters to that job. Do not fill the order with generic exclusions that hide the real stop point.
List the deliverables as well. The client may need photos, test findings, material details, a cause report or documents required for the completed work. Ask for the expected format before the tradie leaves site.
Use this blank brief for managed property plumbing jobs:
Client: [legal or trading name] Property: [address and postcode] Location: [lot, unit, common area or plant room] Work-order reference: [reference] Reported fault: [plain description] Authorised attendance: [inspection / diagnosis / make safe / permanent repair] Included work: [specific tasks] Excluded work: [specific boundaries] Approval limit covers: [attendance, labour, materials and other included costs] Stop point: [action required before further work] Spending approver: [name and contact] Site contact: [name and contact] Access instructions: [keys, parking, isolation access and restrictions] Required records: [photos, findings, readings and completion documents] Invoice recipient: [name and email] Invoice reference required: [work-order reference or other client reference]
Set plumber approval limits before dispatch
An approval limit controls authorised spending. It does not replace a defined scope.
Ask what the limit includes. Does it cover the attendance already authorised? Does it include materials, equipment or subcontractors? Does it allow a permanent repair, or only investigation and make-safe work?
Do not assume the full limit is available after the call-out or inspection. Record the client’s instruction in the work order.
Define the stop point
Tell the tradie what to do when the work cannot be completed within the authorised scope. A useful stop instruction names the permitted make-safe action, the evidence to collect and the person to contact.
Opening an access panel may show that the leak sits beyond the pipework described in the order. The permanent repair may also exceed the supplied limit. At that point, stop. Photograph the location. Describe the extra work. Price it. Ask the named approver for a variation.
Do not let the tradie keep working because the repair looks sensible. Sensible work can still be unauthorised work.
Do not split one repair across separate labour or material entries to keep each entry below the limit. Renaming the cost does not create authority. Raise the full variation against the original work order.
Confirm access before sending the tradie
Call or message the site contact before dispatch. Confirm the address, lot, appointment window and the name of the person providing access.
Ask about keys, lifts, parking, loading areas, isolation points, occupied rooms and areas the tradie cannot enter. Record any instruction about notifying neighbours or building staff before shutting down a service.
Keep access authority separate from spending authority. An occupant can explain the leak and provide entry without being allowed to approve extra work.
Give the tradie one brief containing the work-order reference, authorised scope, approval limit, stop point and approver details. Do not scatter those instructions across email, text messages and office notes.
If site conditions create a workplace safety question, stop and use the state or territory WHS regulator for that safety question. Do not use a WHS body to decide plumbing licence scope or strata payment responsibility.
Diagnose against the work order on site
Start with the reported location. Identify the exact fixture, pipework, service or equipment involved. Record whether the fault matches the work order.
The tradie should capture:
- Arrival and departure records.
- Exact fault location.
- Visible conditions before work.
- Tests performed and findings.
- Immediate risk and make-safe action.
- Labour used on the authorised task.
- Materials fitted or consumed.
- Photos before, during and after the work.
- Work that remains incomplete.
Tie every note to the property, lot or common-area location. “Leak repaired” is not a useful completion record. State what leaked, where it was, what work was completed and what was tested afterwards.
If the fault, access or affected pipework differs from the order, compare the new condition with the authorised scope. Do not stretch the original wording to cover whatever appears after access is opened.
Raise and approve a strata plumbing variation
A variation should tell the approver what changed, why the original scope no longer covers the job and what you propose to do next.
Write it against the original work-order reference. Include:
- Property and exact work location.
- Original authorised task.
- Condition found on site.
- Work completed before the stop point.
- Extra labour and materials proposed.
- Access, isolation or reinstatement effects.
- Revised completion position.
- Variation price and any stated exclusions.
- Name of the person asked to approve it.
Photos support the explanation. They do not replace it. The approver should not have to interpret a photo of open pipework to understand the requested work.
For more detail on writing the document, use the plumber variation process.
Price labour, materials and markup
Build the variation from cost. Include labour cost, materials, equipment, subcontractors and any job-specific overhead allocation. Then add your markup to reach the selling price.
Markup is the amount added to cost. Margin is the profit left as a share of the selling price. They are not the same calculation. Use your own cost records rather than a market rate. The Australian job pricing guide explains the full labour, materials and markup framework.
Send the complete variation to the named spending approver. Record the approval, approver’s name, time and written reference before restarting. If urgent make-safe work has separate authority, complete only that authorised action while the permanent repair waits.
Worked example: keep the documents connected
The Oak Street house example is an electrical job, but the document control applies to plumbing work as well. All figures below are sample currency units, not a rate card.
R. Chen’s job at 14 Oak Street covered a bathroom exhaust fan and four LED downlights. Quote Q-1847 totalled 1,105. 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.
The original job cost was 850. Measured against the original quote, profit was 1,105 − 850 = 255. Margin was 255 ÷ 1,105, or about 23%. Markup was 255 ÷ 850, or 30%.
The costs of the 160 variation are not given. Do not calculate profit using the 1,265 invoice and the 850 original job cost. Close the original scope and the variation with their own supporting cost records.
Close plumber strata work with one matching record
The completion notes, original work order, approved variation and invoice must describe the same job. Use the property, location and work-order reference on every document.
Write the invoice so the client can see the original authorised work separately from each approved variation. Do not bury extra work inside a larger labour line. Include the variation reference and approval record beside the added charge.
Attach the records requested by the client. These may include photos, findings, test results and completion documents. Send them to the named contact rather than assuming accounts will find them in an email chain.
Before sending the invoice, compare it with the work order:
- The client and billing details match.
- The work-order reference is present.
- The original scope matches the authorised order.
- Every extra has a variation approval.
- The completion record names the exact location and result.
Use the invoice writing guide when setting out the final bill and payment details.
If the client rejects an invoice line, do not argue from memory. Open the work order, variation and approval record. Find the authority for that line. If it is missing, fix the control gap before the next attendance.
Review the job before accepting the next order
Close the cost record after the invoice goes out. Compare the authorised scope with actual labour, materials, equipment and subcontractor costs. Keep original work and variations separate so you can see which part moved.
A profitable month can hide a bad job. Review the job itself. The job-costing close-out guide gives you the checks for estimated cost, actual cost and job profit.
Look for the control failure that created wasted time. It may be a missing lot number, an unclear access instruction, no named approver or a limit that did not say what it covered. Change the intake field that allowed the problem through.
Yes Foreman can keep the work-order reference, site notes, variation approval and invoice trail on the same job. That matters only after your team has agreed on the authority fields and stop point.
Before you accept the next plumber strata work booking, add the missing authority and access fields to your intake form. Send the revised form with the next request for clarification, and do not dispatch until it comes back complete.
