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
