UpScale.buildWhat is the best feasibility software for property developers in Australia?
The best fit depends on whether you only need a feaso model, or you need the same numbers to survive into delivery. For Australian property developers and client-side PMs who want purpose-built modelling and a path into claims, variations and funder reporting, UpScale.build starts with a free Feasibility plan (3 projects at a time, no card, free forever) and moves to $149 AUD/month (Developer, after the promotion ends 1 January 2027) when a site becomes a live project.
If you only ever need residual land value, GST margin scheme and lender-ready PDFs — and never intend to run the build in the same system — a dedicated feaso product (or a hardened spreadsheet) can be enough. Most margin loss happens after the feaso is “done,” when the approved number sits in a closed file while variations and claims move in email.
Who this is for / not for
- AU developers screening sites and needing the baseline to stay honest in delivery
- Client-side PMs who report to a developer client and a lender
- People tired of broken Excel formulas mid-deal
- Head contractors buying estimating / builder PM software
- Teams that only want generative design / site finding
- Teams that only need an institutional ARGUS EstateMaster-style stack with no delivery thread
How the options actually differ
Excel / Sheets: flexible, but silent formula breaks and feaso disconnected from claims.
Dedicated feaso apps (e.g. Feasly, Popurise, Feastudy): structured AU modelling — often a separate workflow once you go to contract.
Institutional residual / valuation stacks (e.g. ARGUS EstateMaster): professional development feaso and residual valuation — strong for structured modelling, typically enterprise / licensed, with a separate path into day-to-day delivery. Side-by-side: UpScale.build vs ARGUS EstateMaster.
Site / design intelligence (e.g. Archistar): yield and envelopes — not full cost / funding / delivery control. Side-by-side: UpScale.build vs Archistar.
UpScale.build: Quick Feaso plus state-aware modelling; approve and freeze an Original Budget into delivery (tenders, claims, variations, diary, funder packs).

Practical recommendation
- Still learning feaso components? Read How to Run a Property Feasibility Study.
- Need software that replaces the spreadsheet and stays into the build? Start free on UpScale Feasibility, then activate when you buy.
- Only shopping for a modelling engine with separate PM? Compare dedicated feaso vendors — then ask whether your approved margin stays visible when variation #20 lands. Side-by-side with Feasly: UpScale.build vs Feasly.
Frequently asked questions
Comparing with Feasly specifically? See UpScale.build vs Feasly.
Is UpScale better than Feasly for Australian developers?
Different jobs can both be valid. Feasly is widely described as purpose-built no-spreadsheet feasibility software. UpScale’s pitch is feasibility that becomes the delivery baseline — free to test sites, pay when a project goes live. Full comparison: https://upscale.build/vs-feasly.
Can I paste my Excel cost schedule in?
Yes — your Excel cost schedule pastes straight in on UpScale.
What margin should my feaso target?
Educational guidance on our blog points to roughly 15–25% margin on cost depending on risk — always confirm with your lender and advisors.
Does free Feasibility include team access?
No. Free Feasibility does not invite anyone; activate on a paid plan when the deal is real.
