Feature Comparison:
On-Screen Takeoff vs. STACK: What’s the Difference?
This table reflects each platform’s capabilities as documented and observed in current product versions.
| Feature | On-Screen Takeoff | STACK |
|---|---|---|
| Deployment | Windows desktop application. Installed locally for high-performance rendering of large, complex plan sets. Files can be stored on a shared network drive for team access. Optimized for complex plans. | Fully cloud-based. Runs in any browser with no installation required. Accessible from any device with an internet connection. |
| Ease of Use | Feature-rich interface built for experienced estimators. The depth of tooling requires an investment in learning, but that investment pays back on complex projects where simpler tools fall short. | Teams new to digital takeoff may benefit from STACK's simple interface, designed for faster onboarding, especially for single estimators or small teams. That simplicity comes with trade-offs: advanced automation, deep customization, and multi-condition workflows are not part of the platform. |
| AI-Assisted Takeoff | Takeoff BOOST suite: Auto Takeoff detects and measures areas, linear dimensions, and counts across multiple plan pages. Also includes Auto Count, Auto Name, and Auto Link. Users report up to 95% time savings vs. manual takeoff. | Offers STACK Assist (floor plan and roof AI), limited auto-count for symbols one sheet at a time, and automatic plan naming and hyperlinking. Automation is targeted but generally narrower and often depends on add-ons or integrations. |
| Multi-Condition Takeoff | Patented Multi-Condition Takeoff allows estimators to measure multiple items (e.g., framing and drywall) in a single pass, significantly reducing time on repetitive plan types. | Items can be grouped logically, but conditions generally require individual input. More manual steps for complex, multi-layer projects. |
| Plan Version Comparison and Overlays | Multiple adjusting overlays with color-coding allow estimators to instantly identify additions and deletions between plan versions. Quantities update based on detected changes. | Visual overlays are available to compare document versions. Updating takeoff quantities based on changes requires manual adjustment by the user. |
| Project Templates | Fully customizable templates support fast, repeatable project setup across standardized plan types. | Templates are available with standard configurations. Customization options are more limited compared to On-Screen Takeoff. |
| Assembly Customization | Integrates directly with Quick Bid® to create and reuse custom assemblies that combine multiple conditions into a single unit, useful for teams with established estimating libraries. | Custom assemblies are supported, with a growing library of pre-built options. Flexibility is more limited for teams with highly specific assembly requirements. |
| Measurement Tools | Advanced tools including linear cuts and split segments enable precise measurement of partial or irregular building elements. Designed for complex commercial plan types. | A strong set of standard measurement tools covers most common takeoff requirements. Highly fragmented or complex designs may require additional manual steps. |
| Typical Areas and Groups | Estimators can define a standard floor plan or section once and apply it across multiple instances, a significant time saver on projects with repetitive unit types. | Area identification tools are available. Replicating changes across large numbers of instances on complex projects may require additional manual work. |
| Estimating Integration | Native integration with Quick Bid sends takeoff quantities directly into estimates. Also connects with Excel® and ConstructConnect Project Intelligence. | Includes built-in estimating tools, making it more self-contained for teams that don't need a separate estimating platform. Third-party integrations are available, but the connected ecosystem is more limited. |
| Where On-Screen Takeoff Stands Out | Where STACK Stands Out |
|---|---|
|
AI-Powered Takeoff BOOST Takeoff BOOST is the AI suite built into On-Screen Takeoff. It includes Auto Takeoff, Auto Count, Auto Name, and Auto Link. These AI features are designed to reduce manual work across the takeoff process. What this means for you: You can reduce repetitive measurement and setup work while keeping responsibility for the quantities that reach your estimate. |
Cloud-Native Accessibility STACK runs entirely in a browser. No installation, no local setup. Estimators can access their work from any device, anywhere, which makes it well-suited for teams that work across multiple locations or job sites. What this means for you: If remote access or multi-device flexibility is a primary requirement, STACK's cloud architecture is a genuine advantage. Desktop-based platforms require more configuration to support the same kind of access. |
|
Patented Multi-Condition Takeoff On-Screen Takeoff’S Multi-Condition Takeoff lets estimators measure multiple items (framing, drywall, insulation, paint) in a single pass over a plan instead of tracing the same wall four separate times. What this means for you: On multi-trade commercial projects, this isn't a minor convenience. It can cut takeoff time by hours per bid. Platforms that require individual condition input don't scale the same way when complexity increases. |
Simple Interface STACK's interface is designed for speed of adoption. Teams newer to digital takeoff can typically get up and running without extended training or configuration time. What this means for you: A simple interface lowers the barrier to entry, which matters for smaller teams or contractors just transitioning from paper-based takeoff. Keep in mind that the same simplicity that makes onboarding easy also limits what the platform can do when project complexity increases. |
|
End-to-End Preconstruction Integration On-Screen Takeoff connects natively with Quick Bid for estimating, Excel for cost modeling, and ConstructConnect Project Intelligence for access to 800K+ active construction projects—all without re-entering data between systems. What this means for you: Your takeoff doesn't sit in isolation. Data flows from project discovery through takeoff and into the estimate, which reduces errors, saves time, and gives you a complete picture of every bid opportunity. |
Built-In Estimating Tools STACK's interface is designed for speed of adoption. Teams newer to digital takeoff can typically get up and running without extended training or configuration time. What this means for you: A simple interface lowers the barrier to entry, which matters for smaller teams or contractors just transitioning from paper-based takeoff. Keep in mind that the same simplicity that makes onboarding easy also limits what the platform can do when project complexity increases. |
Making the Right Call
Trade-offs to Consider
No platform is the right fit for every team. Here are the honest tradeoffs each platform asks you to make.
| If you choose On-Screen Takeoff | If you choose STACK |
|---|---|
| You get deeper automation and feature depth in exchange for a steeper initial learning curve | You get fast onboarding and cloud accessibility in exchange for less automation depth on complex projects |
| You gain tight integration with Quick Bid and Project Intelligence but you're working within a Windows desktop environment, not a browser | You get a simple interface that's easy to start with, but multi-condition and multi-trade workflows require more manual steps |
| You have advanced tools for complex, high-volume commercial work, which requires more upfront configuration than a simple platform | You get an all-in-one takeoff and estimating tool with a less extensive integration ecosystem than ConstructConnect |
| You benefit from Takeoff BOOST, which adds the most value for teams doing high volumes of similar work | You benefit from browser-based remote access, but without the high-performance rendering that a desktop application provides for large plan sets |
