Pros & Cons
Pros
- AI-powered takeoff (STACK Assist) automates measurements and counts by trade — a genuine time-saver for high-volume estimating that most AU competitors do not offer
- Unlimited viewer seats on all plans mean project managers, site supervisors, and clients can review plans and estimates without additional licence costs
- 100% cloud-based with no downloads required — accessible from any browser on Mac, PC, tablet, or mobile, with support for both metric and imperial units
- Mature platform with 1,000+ user reviews on Capterra/G2 and Inc. 5000 recognition, indicating a well-established and actively developed product
- Comprehensive document control with version comparison overlay, full-text search, and concurrent viewing — strong for teams managing large plan sets across revisions
- Supports 10+ construction trades with pre-built item and assembly libraries, making it versatile for multi-trade subcontractors and general contractors
- Open API available for custom integrations, providing flexibility for larger organisations with existing software ecosystems
- 7-day free trial with Pro-level features and no credit card required lowers the barrier to evaluation before committing to annual pricing
Cons
- No Xero or MYOB integration — a critical gap for Australian construction businesses, as Xero is the dominant accounting platform in the AU market
- All pricing in USD only with no published AUD rates — at USD $2,599–$3,999/user/year (~AUD $4,000–$6,200), significantly more expensive than local alternatives like CostMiner or Buildxact
- US-based support only with Eastern Time business hours (9am–5pm ET / 12am–8am AEST) — no Australian phone number or local support team, meaning real-time support during AU business hours is unavailable
- Data hosting location and cloud provider not publicly disclosed — Australian data sovereignty cannot be confirmed, which may be a concern for businesses handling sensitive project financials
- Annual billing only with no monthly payment option — requires upfront commitment of USD $2,599+ per user, which is a significant barrier for small builders wanting to trial the platform beyond the 7-day free period
- No end-to-end job management for residential builders — lacks scheduling, client portals, live AU supplier pricing, and progress photos that Australian-focused platforms like Buildxact include
- BNI cost library (Pro tier) is US-focused — Australian material and labour cost data would need to be manually entered or imported, reducing the out-of-the-box value for AU users
Who Is STACK Best For?
- Large Subcontractor
- Commercial Contractor
- Multi Trade Estimator
- Procore User
STACK may not be the best fit for:
- Small Residential Builder
- Sole Trader

- Builder Needing Au Support

Frequently Asked Questions
How much does STACK cost in Australia?
STACK does not publish Australian-dollar pricing. All listed prices are in USD. Takeoff & Estimate plans range from USD $2,599/user/year (Standard with basic takeoff) to USD $3,999/user/year (Pro with full estimating and BNI cost library). At current exchange rates, this translates to approximately AUD $4,000–$6,200/user/year. Build & Operate (field collaboration) is an additional USD $599–$699/user/year. A 7-day free trial is available for takeoff and estimating, and 30 days for field collaboration. Contact STACK at (866) 702-6078 or contact@stackct.com for potential AUD pricing arrangements.
Does STACK integrate with Xero or MYOB?
No. STACK does not currently integrate with Xero or MYOB. Its accounting integration is limited to QuickBooks. For Australian builders who rely on Xero (the dominant accounting platform in AU construction), this is a significant gap. STACK does offer an Open API which could potentially be used for custom integration, but there is no native or marketplace connector for Xero or MYOB as of March 2026.
Does STACK have Australian support?
No. STACK's support team is US-based, operating on Eastern Time business hours (9am–5pm ET), which translates to approximately 12am–8am AEST the following day. There is no Australian phone number — the US toll-free number is (866) 702-6078 and contact email is contact@stackct.com. Live in-app chat, a help centre (support.stackct.com), and webinar training are available. For Australian users needing real-time support during business hours, this overnight support window is a limitation.
Where is STACK data hosted?
STACK does not publicly disclose its data centre location or cloud provider. The company is SOC 2 compliant and uses Auth0 for authentication with SSO and two-factor authentication. Note: STACK Infrastructure (stackinfra.com), which has data centres in Melbourne, Canberra, and Sydney, is a completely separate company unrelated to STACK Construction Technologies (stackct.com). Australian data sovereignty cannot be confirmed — contact STACK sales directly for hosting details if this is a requirement.
How does STACK compare to Buildxact for Australian builders?
STACK offers more powerful takeoff and AI features (STACK Assist for automated measurements) and serves a broader range of trades, while Buildxact provides a more complete Australian-focused workflow including scheduling, client portals, live supplier pricing, Xero integration, and AUD pricing. STACK is better for large estimating teams needing enterprise-grade takeoff tools; Buildxact is better for small-to-medium residential builders wanting an all-in-one platform with Australian support and integrations. STACK is also significantly more expensive (USD $2,599–$3,999/user/year vs Buildxact's AUD $169–$449/month).
What AI features does STACK offer?
STACK Assist uses AI to automatically perform takeoff measurements and item counts by trade. Premium and Pro tiers include Symbol Search & Recognition (identifies and counts repeated symbols across all drawing pages), Automatic Plan Hyperlinking (links drawing references), and Automatic Plan Naming. These AI features can significantly speed up repetitive takeoff work. The Standard tier includes only basic AI capabilities. STACK claims users complete takeoffs 3–4x faster with AI automation.
