VIABUILD vs Built Simple
Built Simple is Australian construction software aimed at small builders, tradies and owner-builders who want to run jobs without enterprise complexity. VIABUILD is the Construction Operating System for Australian residential builders: one connected system where a number entered once flows everywhere, with Oryn intelligence built into every module.
Verdict
VIABUILD fits if you want one connected operating system for the whole job, where a number entered once flows everywhere, with Oryn reading your invoices and plans, live cost control, ViaSite on site and a flat price, and you expect the business to keep growing. Built Simple fits if you’re a sole trader, small crew or owner-builder who mainly needs a light, tidy way to schedule, quote and track a handful of jobs, and a deliberately simple Australian tool is exactly the fit.
Published pricing. VIABUILD: $555 a month for the whole platform including three users, additional users $65 a month, AUD inclusive of GST, month-to-month with no lock-in; seven days free, then a first month at $299. Built Simple: Tiered plans by team size in AUD with a free tier and trials; confirm current plans and limits with the vendor.
Connects to Xero? VIABUILD: Yes. Native two-way sync: approved bills and progress claims push to Xero with tracking categories applied. Built Simple: A Xero connection is referenced in places; confirm its current status and depth directly with the vendor, as accounting sync may still be developing.

01 / Fair positioning
Choosing simple builder software in Australia
Built Simple is a local product, built in Australia and pitched at small and medium builders, sole traders and owner-builders who want the basics done without the clutter of a big platform. Its advertised set covers scheduling, estimating with a takeoff tool, defects and punch lists, document storage and per-project profit and loss. For a one or two person outfit that mostly needs a shared job view and a tidier way to quote, that focus on simplicity is a genuine strength, and worth taking seriously.
The real question a builder is asking is where they are heading. A deliberately simple tool keeps the admin light while the jobs are small. As soon as the work grows, the double entry creeps back in: a quantity re-keyed from the estimate into the budget, a supplier invoice typed into the accounts, a claim rebuilt by hand each month. The tool that felt clean at three jobs starts leaking hours at ten.
VIABUILD is built for that second stage. It is one connected operating system, so a quantity taken off once in estimating flows into budgets, purchase orders and progress claims with zero double entry, and cost control stays live against it. The ViaSite field app puts the same job in the crew’s hands on site rather than in a separate app.
The other difference is intelligence. Oryn™ is embedded across every module: it reads the plans, extracts supplier invoices through a dedicated accounts payable inbox, codes the costs, drafts claims and flags variances. Built Simple advertises an AI assistant of its own, so test both on your own plans and invoices. Both are Australian and both sit alongside Xero, so the honest question is how much of the job you want one system to carry.

The differences that matter
Workflow, pricing philosophy, AI AP, estimating, scheduling, Xero, AI agent connectivity and Australian fit, compared dimension by dimension.
| Dimension | VIABUILD | Built Simple |
|---|---|---|
| Category | A Construction Operating System: one connected system where a number entered once flows everywhere. | Australian construction management software pitched as a simple, lightweight tool for small builders and tradies. |
| Embedded intelligence | Oryn is built into every module: it reads plans and invoices, drafts claims and flags variances. | Advertises an AI assistant; confirm its current scope and which modules it actually touches. |
| Accounts payable | Dedicated accounts inbox: Oryn extracts, PO-matches and job-codes supplier invoices for one-tap approval. | An AP inbox that extracts and PO-matches supplier invoices is not advertised as a core workflow; confirm with the vendor. |
| Estimating | Oryn digital takeoff and pricing, built to stay fast on large plans; quantities flow to budgets and POs. | Estimating with a measuring takeoff tool and reusable templates is advertised; check takeoff depth on your own plans. |
| Scheduling | Task-based, goal-driven schedule with real dependencies, milestones and baseline tracking. | Drag-to-reschedule scheduling with colour-coded trades is advertised; confirm whether it carries real dependencies and baselines. |
| Cost control | Live budget vs committed vs actual with Oryn variance alerts at 2%, 5% and 10%. | Per-project profit and loss and budgeting are advertised; confirm how live the committed position is, not just actuals. |
| Xero integration | Native two-way Xero sync: approved bills and progress claims push with tracking categories. | A Xero connection is referenced in places; confirm its current status and depth directly with the vendor, as accounting sync may still be developing. |
| Pricing philosophy | Flat platform price in AUD, everything included, three users; month-to-month with no lock-in available. | Tiered plans by team size in AUD with a free tier and trials; confirm current plans and limits with the vendor. |
| Australian builder fit | Built in Australia for Australian residential builders: GST, BAS, Xero, local claims workflow. | Built in Australia for local builders too; the difference is depth and connection, not country of origin. |
| AI agent connectivity | VIABUILD MCP: compatible AI agents read authorised live data and draft permitted records, preview first, with every call logged. Sending and paying stay with a person. | As of 3 September 2026, we could not find a publicly documented, vendor-supported MCP in Built Simple’s official product or developer documentation. The platform may offer private, partner or recently released capabilities, so confirm current availability directly with the vendor. |

04 / AI agent connectivity
Can your AI agents work inside it?
Whether each platform lets a compatible AI agent read live business information and perform permitted actions through a vendor-supported MCP, and the controls around it. Competitor statements are traced to the vendor pages listed under the table; where we could not find a capability in those pages, the row says so rather than asserting absence.
| Dimension | VIABUILD | Built Simple |
|---|---|---|
| Official MCP | Yes. VIABUILD MCP, built and supported by VIABUILD as part of the platform. | No publicly documented capability found |
| AI-agent connectivity | Yes. Any MCP client over Streamable HTTP; verified with claude.ai custom connectors, Claude Desktop and Claude Code. | No publicly documented capability found |
| Agent read access | Yes. Jobs, budgets, profitability, estimates, quote packages, catalogue prices, purchase orders, supplier bills, progress claims, variations, contracts, schedule, contacts and document metadata, scoped to one workspace. | No publicly documented capability found |
| Agent write access | Yes, as drafts. Writes are an opt-in scope, preview by default and persist only on an explicit call. Sending, paying, emailing, approval workflows and Xero stay off. | No publicly documented capability found |
| Human approval controls | Yes. Every write previews first. Nothing an agent drafts is sent, paid or pushed to Xero; those steps happen in the app, by a person. | No publicly documented capability found |
| Role and permission enforcement | Limited. Only owners and admins can issue a token, and each token carries chosen scopes for one workspace. Per-user role scoping is on the roadmap. | Unable to verify |
| Auditability | Yes. Every tool call is logged with token, workspace, tool, outcome and time. Arguments are deliberately not stored. Owners and admins can query the log; an in-app audit screen is on the roadmap. | Unable to verify |
| Public API | No general public REST API. MCP is the supported programmatic surface. | No publicly documented capability found |
| Webhooks | No publicly documented webhooks. | No publicly documented capability found |
| Custom agent support | Yes. Any MCP-compatible client or custom agent that speaks Streamable HTTP. | No publicly documented capability found |
| Documentation availability | Yes. Public feature and setup documentation on this site. | No publicly documented capability found |
Built Simple lists an in-product assistant, Mat AI, on its plans.
Competitor information last checked: 3 September 2026. Where we could not find a capability in the vendor’s official product or developer documentation we say so; the platform may offer private, partner or recently released capabilities, so confirm current availability directly with the vendor. VIABUILD’s side is verified against the application on the same date. See VIABUILD MCP for what the connector does and does not do.
05 / FAQ
Common questions.
Yes, and both are built in Australia, so this is a fair like-for-like on home ground. The difference is scope. Built Simple leans into being simple for small builders and tradies. VIABUILD is a connected operating system where estimating, cost control, progress claims, accounts payable and the ViaSite field app are one system, with Oryn intelligence inside each. Which fits depends on how much of the job you want the software to carry.
Connection and intelligence. In VIABUILD a number entered once flows from takeoff into budgets, purchase orders and claims with no re-keying, and Oryn reads plans and supplier invoices for you. A deliberately simple tool tends to keep those steps separate, which is fine at a few jobs and starts costing admin hours as the work grows. Test both against the volume of jobs you actually expect to run.
VIABUILD has a native two-way Xero sync, where approved bills and progress claims push across with tracking categories. Built Simple references a Xero connection, but the status and depth are worth confirming directly with the vendor before you rely on it, since accounting integration for newer tools is sometimes still being built out.
Yes. VIABUILD migrates you from any platform, done for you on yearly plans, including suppliers, cost codes, products and templates. You can run both side-by-side on a live job during switchover until you are confident it holds up on real work.
