BuzzBID is the modern computer vision takeoff and estimating platform from Leonard Buzz, the same industry veteran who created Quick Bid in 1988 and created On-Screen Takeoff, which started the electronic measurement market in 1994. If you already know OST and Quick Bid, BuzzBID feels familiar out of the gate. BuzzBID uses ClickONCE™ computer vision to automate repetitive takeoff measurements, publishes its pricing openly, and combines takeoff and estimating in one integrated application.
The BuzzBID vs. On-Screen Takeoff question comes up almost every day inside commercial specialty contractor shops, and the honest comparison starts with a simple fact: the same person built both. Leonard Buzz created Quick Bid in 1988 and later created On-Screen Takeoff, then co-founded BuzzBID with Chris Buzz in 2019 to build a modern replacement that uses computer vision from the ground up. This comparison walks through what actually changed, what stayed the same, where BuzzBID pulls ahead, and where OST or Quick Bid may still make sense for your team.
Who Created On-Screen Takeoff and Quick Bid?
Leonard Buzz created both On-Screen Takeoff and Quick Bid. He founded On Center Software to sell them, and the company later became part of ConstructConnect in 2016. In 2019, Leonard co-founded BuzzBID with Chris Buzz to design a next-generation takeoff and estimating platform that delivers performance enhancements with modern computer vision technology.
That history settles the "old versus new" framing most comparison sites lean on. BuzzBID does not come from a startup trying to unseat the incumbent. It comes from the person who built the incumbent, applying three decades of hard-won lessons to the technology he wanted decades ago.
What Is the Difference Between BuzzBID and On-Screen Takeoff?
The core difference between BuzzBID and On-Screen Takeoff is that BuzzBID uses ClickONCE computer vision to take off entire assemblies from a plan in a single click, while OST relies on manual click-and-drag measurement of individual conditions. BuzzBID also bundles takeoff and estimating inside one application, publishes its pricing openly, and covers nine specialty trades out of the box. OST separates takeoff (OST) and estimating (Quick Bid) across two products in the ConstructConnect suite and keeps pricing behind a sales-quote process.
Three specific differences drive the day-to-day experience.
Speed and Automation
BuzzBID's ClickONCE computer vision detects walls, ceilings, doors, tiles, and other repetitive plan elements and generates the takeoff quantities automatically. ClickONCE™ uses computer vision to automate measurements that traditionally require repetitive manual clicking and tracing, dramatically reducing takeoff time.
Integrated Estimating vs. Two Products
BuzzBID Advanced combines takeoff, assembly-based estimating, pricing, and work in place tracking inside one application. Your assembly quantities flow directly into the Estimate page, where you apply costs for labor, material, equipment, subcontract, and other categories. OST handles takeoff and Quick Bid handles estimating, and customers who use both products depend on the integration between them to keep data in sync.
Modern Interface and Workflow
BuzzBID uses a feature-layering interface that stays clean for simple bids and exposes advanced tools only when you need them. Reviewers of On-Screen Takeoff say that its interface feels dated compared to newer options, even after Takeoff Boost joined the lineup. A longtime OST estimator sitting down with BuzzBID for the first time recognizes the mental model immediately, while the click-heavy steps drop away.

Honest, Transparent Pricing
BuzzBID publishes its complete pricing on the website, and every customer pays the same price. Standard runs $100 per month or $1,050 per year, Advanced runs $250 per month or $1,750 per year, and FireShield runs $300 per month or $2,450 per year. Every subscription includes software updates, live support, and unlimited training. See the full breakdown of tiers and features on the BuzzBID pricing page.
On-Screen Takeoff and Quick Bid do not publish standard pricing on their public product pages. Prospective customers contact ConstructConnect sales for current pricing and licensing terms. That model made sense in the 1990s, but it requires prospective customers to contact sales before they can compare pricing directly. BuzzBID took the opposite approach on purpose so a specialty contractor can quickly determine whether the software fits the budget.
Can I Switch From On-Screen Takeoff to BuzzBID?
Yes, switching can be straightforward because Leonard designed BuzzBID with OST and Quick Bid workflows in mind. Estimators who spent years in OST report that BuzzBID feels immediately familiar, since the mental model for scales, conditions, layers, and assemblies carries over directly. Every BuzzBID subscription also includes unlimited live training, so onboarding stays inside the price you already paid.
Three switching factors matter in planning. First, your historical OST files stay in OST format, teams can run both products in parallel on legacy projects while adopting BuzzBID for new bids. Second, BuzzBID supports single-user or multi-user SQL Server configurations, giving teams flexible desktop deployment options. Third, unlimited training lets the whole estimating team ramp up at once instead of learning in shifts.

All Nine Trades BuzzBID Supports
BuzzBID covers nine commercial specialty trades: drywall, metal framing, plaster, EIFS, stucco, acoustical ceilings, fireproofing, insulation, and painting. Each trade gets dedicated ClickONCE workflows and AddOnASSEMBLY templates, so estimators skip the from-scratch build every time. FireShield adds specialized structural member detection, UL Fire Test integration, board foot calculations, and inspector spray reports for cementitious, intumescent, and spray foam fireproofing.
On-Screen Takeoff works across a broader range of trades in a more general way, since it acts as a horizontal takeoff platform. If your work sits inside the nine trades If your work sits inside the nine trades BuzzBID targets, its trade-specific automation can eliminate many of the manual steps associated with general-purpose takeoff workflows.
Recognition From the Industry
BuzzBID Advanced won the 2025 AWCI Excellence in Construction Innovation Award from the Association of the Wall and Ceiling Industry. AWCI member companies judge the award entries themselves, and the criteria measure real productivity gains, safety improvements, and scope expansion in contractor operations. Full award details and past winners live on the AWCI Excellence in Construction Innovation Award page.
Industry-judged recognition provides additional support for BuzzBID’s focus on improving estimator productivity through innovation.
When On-Screen Takeoff or Quick Bid Is Still the Right Choice
Some teams should stick with On-Screen Takeoff or Quick Bid, at least for now. Three situations stand out:
- Deep ConstructConnect integration. If your team relies on ConstructConnect Project Intelligence for lead flow across 800,000+ private and public projects, OST plugs directly into that ecosystem. BuzzBID is a takeoff and estimating platform, not a project-data source.
- Long-established OST and Quick Bid workflows across large teams. Contractors with hundreds of active OST files, custom templates, and trained estimators often run OST and BuzzBID in parallel through a renewal cycle rather than switch everything at once.
- Trades and divisions outside BuzzBID's nine. BuzzBID focuses on Divisions 5-10 specialty work. Heavy civil, mechanical piping, and electrical estimators may need a broader horizontal tool or a trade-specific option BuzzBID does not target today.
For the specialty commercial trades BuzzBID targets, its trade-specific automation can make it a compelling alternative to traditional OST and Quick Bid workflows.
What Real Users Say
The customer voice on BuzzBID stays unusually direct about the OST and Quick Bid comparison. One reviewer, a commercial framing, drywall, and acoustical contractor with 40+ years in the industry that bids $200 million a year, writes that bidding volume has increased exponentially since switching to BuzzBID. A drywall contractor's estimating team in Wyoming that has also used STACK, Togal AI, and On-Screen Takeoff describes BuzzBID as the best of the group for accuracy, pricing, and customer service.
One particularly notable line comes from a longtime OST and Quick Bid user who calls BuzzBID the "next evolution" and describes the platform as "OST and Quick Bid on steroids." That framing lands because the person who created OST and Quick Bid is the same person building BuzzBID today, so the DNA carries over, with three decades of learning applied to a modern computer vision engine.
