Perth spreadsheet work is not generic spreadsheet work: joint-venture billing across working interests that shift mid-year, cost-per-tonne models where the denominator changes between tabs, FIFO roster costing, and BAS workbooks that tie back to Xero or MYOB. We match you with vetted remote Excel consultants and VBA developers who have built those things before — priced in Australian dollars, working AWST.
Describe Your Project — Get Matched FreeAll work remotely, over screen share and shared workbooks. You speak to the builder, not an account manager.
Financial Modelling Specialist
Three-statement models, valuations and forecasting, plus automation builds. Often brought in to pressure-test a model before it reaches a board or a lender.
Data Analysis & Dashboard Specialist
Dashboards that refresh through Power Query, and board packs that survive a question about where a number came from.
VBA Automation Developer
VBA for report assembly, file merges and reconciliations, with error handling and documentation so your team can maintain it.
Reporting & Compliance Analyst
JV billing schedules, BAS-ready workbooks and month-end packs built reconciliation-first, so they tie back without manual adjustment.
Data Integration & Power Query Specialist
Connects Excel to accounting, CRM and ERP exports and builds consolidated reporting that refreshes on demand.
Describe the workbook and we’ll shortlist one to three people who have built it before. No cost, no obligation.
Get Matched With a Specialist — FreeA short walkthrough of what happens between posting a project and getting a finished workbook back — how we shortlist, how the scoping call works, and what you receive at handover.
Prefer to skip the video? The four steps are the same: describe the project, get a shortlist inside about 20 minutes, talk to the builder directly on a free scoping call, then work starts — usually the same day, with a fixed quote and an NDA signed first.
This is the most common serious build for Perth clients, and the one most often done badly. A JV billing workbook a partner can audit needs five things:
Send the current file and the partner statement. We’ll tell you what it would take to make the two reconcile.
Send Us Your Workbook — Free ReviewWhen a cost-per-tonne model produces a number the site manager does not recognise, the cause is nearly always the denominator. Tonnes mined, milled and sold are three different figures, and a model that switches between them across tabs gives unit costs that reconcile to nothing. Define each denominator once in a driver sheet, tag every cost line to the one it belongs to, and make the model state which basis it is on. Strip ratio, grade and recovery then become explicit drivers instead of assumptions baked into a hardcoded figure.
FIFO labour is its own build: roster pattern, heads on site by swing rather than headcount, flights per rotation, camp per bed-night, and the allowance rules from the agreement. Most models we are asked to fix cost labour at an average rate per head per month — which hides exactly what the model was built to show.
A BAS workbook is a mapping problem before it is a maths problem. The build that holds up maps tax codes from your Xero or MYOB export to the BAS labels as a visible table, not nested formulas nobody can audit later. G1 reconciles to reported revenue with timing differences on their own line; capital acquisitions in G10 sit apart; W1 and W2 tie to the payroll report rather than being typed in. Power Query handles ingestion, so next quarter is a refresh, not a rebuild. Your registered tax agent signs off the lodgement.
Two reviews from Australian clients of Arun K., both delivered remotely.
I have used Arun a few times now and the quality maintains high with a positive approach to client relationships. Highly recommend.
Arun was excellent at making suggestions about the progress of this project, as a result of which the outcome was better than we had originally imagined when we were in the planning phase — very happy with the assets which Arun delivered to us.
Rates are lower than a Perth firm's because delivery is remote — no office, no account manager, no margin on a junior's time. From $40 an hour in Australian dollars, no minimum project size, and defined work quoted as a fixed fee.

If you need someone in the room, if procurement requires a local ABN and Australian professional indemnity cover, or if the real problem is a Power BI or data-warehouse rollout, hire locally. For defined deliverables under roughly $15,000, a remote specialist is faster and cheaper.
Defined scope gets a fixed fee in Australian dollars, usually the same day. No retainer, no minimum.

How much does an Excel expert in Perth, WA charge?
Data cleanup starts at $40 an hour in Australian dollars. Dashboards run $50–75, Power Query $55–80, VBA automation $65–95, and financial modelling $75–110. A Perth consulting firm typically charges $180–330 an hour for comparable work, so smaller jobs often finish for a few hundred dollars in total.
Can you build a joint-venture billing spreadsheet with working-interest allocation?
Yes. The usual build is an effective-dated working-interest table so a farm-in mid-period allocates correctly, cost allocation by AFE, a cash-call ledger carrying each partner's balance forward, and a variance sheet reconciling the operator's statement to your ledger line by line — with locked inputs and a visible change log so it survives a JV audit.
Do your Excel experts work remotely or on-site in Perth?
All support is remote — screen share, calls and shared workbooks, with drafts reviewed as the work progresses. That is why rates start at $40 rather than a firm's $200-plus. If you need someone in the room for training or a workshop, a Perth-based firm is the better fit and we will say so.
What times can I work with an Excel expert in Perth?
Specialists cover Australian business hours on AWST, so you are on the same clock through the working day. Urgent work can begin the same day. The team is based overseas and works your hours; there is no Perth office.
Who owns the workbook when the project is finished?
You do. You receive the unlocked file, the VBA source, any Power Query steps and a short written handover. Nothing is password protected against you, and no consultant keeps a copy unless you ask them to for ongoing support.
