On-Screen Takeoff®

vs zzTakeoff:

An Honest Comparison

For Contractors and Estimators

On-Screen Takeoff with Takeoff BOOST™ and zzTakeoff both help teams turn construction drawings into measurable quantities. However, they are built around different priorities: On-Screen Takeoff focuses on estimator-controlled takeoff depth, repeatable measurement workflows, and an optional connection to Quick Bid®, while zzTakeoff emphasizes browser access, real-time collaboration, and a cloud-first takeoff experience.

Quick Answer:

How On-Screen Takeoff and zzTakeoff Compare

On-Screen Takeoff with Takeoff BOOST is a strong fit for preconstruction teams that need AI-assisted measurement inside a structured takeoff workflow. Takeoff BOOST includes Auto Takeoff for preliminary area, linear, and count measurements, along with Auto Count, Auto Name, and Auto Link. Estimators review and refine the results rather than treating the AI output as a finished bid.  

zzTakeoff is a strong fit for teams that prioritize browser-based access, online collaboration, and a fast-to-adopt takeoff workspace. Key features include real-time multi-user editing, area, length, and count measurements, AI-assisted page naming and scaling, reusable templates and assemblies, and import/export options.  

The practical difference is workflow depth. The easiest tool to start with is not always the easiest tool to grow with. The right choice depends on whether your team needs a fast, accessible takeoff workspace today or a more structured workflow that can support complex plan sets, revisions, change orders, and connected estimating over time.

Multi-Condition Takeoff

On-Screen Takeoff
Select multiple items and complete their takeoffs all at once, saving time and reducing repetitive work.
STACK
Users can group items, but conditions require input to create every time, resulting in slower takeoffs for multiple items.

Multiple Adjusting Overlays

On-Screen Takeoff
Overlay multiple drawing versions and quickly spot changes, like what’s been added or deleted.
STACK
Provides visual overlays for detecting changes, but all takeoff updates are manual.

Project Template Options

On-Screen Takeoff
Fully customizable templates for a faster project setup.
STACK
Limited template options with fewer customization possibilities.

Assembly Customization

On-Screen Takeoff
Easily integrate with Quick Bid to create and reuse custom assemblies that combine multiple conditions into one unit.
STACK
Allows custom assemblies, but with fewer pre-built options and less flexibility.

Measurement Tools

On-Screen Takeoff
Advanced tools like linear cuts and split segments allow precise measurements of partial or complex elements.
STACK
More basic measurement tools, making partial or complex elements harder to measure accurately.

Typical Areas and Groups

On-Screen Takeoff
Define a standard section once and apply it across multiple instances in a project.
STACK
Offers tools for identifying areas, but requires more manual setup and lacks the same flexibility that OST provides.
Where On-Screen Takeoff Stands Out Where  zzTakeoff Stands Out
Real-Time Estimator Control 
On-Screen Takeoff puts the estimator in the seat. Takeoff BOOST can detect and measure areas, linear dimensions, and counts across plan pages, while the estimator reviews and refines the results before they are used in the bid.

What this means for you: When a late addenda lands before bid day, your team can respond in the takeoff workflow rather than waiting for an outside measurement delivery.		 Browser-Based Team Access 
zzTakeoff runs in a browser on PC, Mac, or mobile and documents real-time multi-user editing, live updates, presence indicators, and change tracking.

What this means for you: Distributed teams can access the same project online and collaborate without installing a Windows desktop application or passing files back and forth.
AI-Assisted Measurement with Estimator Review 
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 get a measurable head start on repetitive measurement without losing the control that matters when the bid is due. 		 AI-Assisted Setup and Plan Search 
zzTakeoff documents AI-assisted page naming and scaling, AI Auto Count, PDF search, and prompts for plan details. Teams that need AI to generate area, linear, and count measurements should confirm zzTakeoff's current product scope before making a purchase decision.

What this means for you: If your priority is reducing plan setup and navigation time in an online workspace, zzTakeoff offers a focused set of AI-assisted tools to evaluate.
End-to-End Preconstruction Integration  
On-Screen Takeoff connects natively with Quick Bid for estimating, Microsoft Excel for cost modeling, and ConstructConnect Project Intelligence for access to 800,000+ private and public projects. Your takeoff doesn't sit in isolation, but instead flows from project discovery through takeoff and into the estimate. 

What this means for you: A more connected workflow from project discovery through takeoff and estimating, with fewer manual handoffs between ConstructConnect tools. 		 Online Takeoff with File Exchange 
zzTakeoff documents Excel and PDF export, along with PlanSwift and Bluebeam import options. Its migration notes say that basic project and template data can transfer, while formulas, complex properties, advanced markup styles, and some assemblies may require manual recreation or adjustment.

What this means for you: zzTakeoff can fit a team that wants an online takeoff workspace, but validate what will carry into your existing templates, assemblies, and downstream estimating process.
If you choose On-Screen Takeoff
You get real-time estimator control and the ability to respond to addenda immediately, but you're operating a feature-rich Windows desktop application that takes investment to learn.
If you choose Bobyard
You get done-for-you takeoff with a human QA layer, but your estimator is removed from the measurement loop, and the DFY model's 24–72 hour window is unusable on same-day addenda.
If you choose On-Screen Takeoff
You gain native integration with Quick Bid, Project Intelligence, and Excel, but you're working within a desktop environment, not a browser.
If you choose Bobyard
You gain a highly rated platform with strong recent reviews, but billing complexity has been flagged in user reviews and output format mismatches have required manual re-entry for some customers.
If you choose On-Screen Takeoff
You get patented Multi-Condition Takeoff and depth that scales to complex multi-trade jobs, which requires more upfront configuration than a simpler tool.
If you choose Bobyard
You benefit from $48M in Series B funding and active product development, but this is a company a fraction of the age of On-Screen Takeoff, still expanding its integrations with existing estimating systems.
If you choose On-Screen Takeoff
You get a full suite of AI tools with Takeoff Boost that runs on your schedule, in your workflow. Your estimator reviews and approves every measurement before it reaches a bid.
If you choose Bobyard
You get a service that offloads takeoff from your team, but the quantity deliverable doesn't include pricing, so it connects to your estimating workflow only as an import step, not a native integration.
Making the Right Call

Trade-offs to Consider

The right product is the one whose trade-offs match the way your team works. A simple tool may reduce initial friction, while a deeper tool may give estimators more room to manage complexity as the business grows. 

If you choose On-Screen Takeoff If you choose zzTakeoff
You get AI-assisted preliminary area, linear, and count measurements, plus Auto Count, Auto Name, and Auto Link. But estimators still need to review, correct, and refine the output.  You get AI-assisted page naming, scaling, search, and counting-related tools in a browser-based workflow. But teams that need AI to generate area, linear, and count measurements should confirm zzTakeoff's current product scope and test it against their specific plan types and trades before making a purchase decision 
You get Conditions, layers, zones, typical takeoff, bid areas, and Multi-Condition Takeoff for organizing complex scopes. But a configurable workflow can require setup, standards, and estimator training to use consistently.  You get a browser-first workspace with no installation, online access, and real-time collaboration. But a web-based workflow depends on browser and internet conditions. Browser compatibility and mobile support may vary. 
You get an optional path from reviewed takeoff results into Quick Bid for pricing, production information, and bid details. But you are choosing a broader connected preconstruction workflow, not only a standalone markup and measurement workspace.  You get Excel and PDF exports. But migration and downstream workflow fit may require validation. Confirm current migration support directly with the vendor before switching.
