Groundwork
C-100vs On-Screen TakeoffSeptember 20, 2026

A classic. And it drives like one.

On-Screen Takeoff practically invented digital takeoff, and a loyal base in the commercial interior trades has stayed with it for thirty years. It is also Windows-only, sells estimating as a second product, and will not publish a price.

All comparisons
The short version

Choose On-Screen Takeoff if you are a commercial interiors contractor whose bid pipeline runs through OST, Quick Bid and eQuotes and it is working — that workflow is genuinely deep and nothing here replaces the supplier network. Choose Groundwork Takeoff if you want takeoff and estimating in one modern app on Mac or Windows, and a price you can read without a sales cycle.

Competitor figures are read off that vendor's own pricing page on September 20, 2026; the sources are listed at the foot of this page. A vendor who publishes no price gets no number here — the empty cell is the finding.

There is no saving figure on this page. On-Screen Takeoff publishes no comparable price, so there is nothing to subtract a Groundwork seat from. A number here would be somebody's estimate wearing a vendor's name.

The price we are not going to print

ConstructConnect publishes no price for On-Screen Takeoff. Buyers are directed to contact sales.

You will find numbers for it anyway — a figure in the region of $995 standalone, or around $1,850 paired with Quick Bid, circulates on comparison pages across this category. We are not using them, and it is worth saying why. That range traces back to BuzzBID's own published price list, quoted on a competitor's comparison page. It was never On-Screen Takeoff's number, and repeating it would have made this page one more link in the chain that made it look like one.

So the row in the table above says quote-only and carries no figure. That is the finding. A product whose price you cannot look up is a product you cannot compare on price, and the absence tells you something about how the sale is going to go.

What you are buying, and what you are buying separately

On-Screen Takeoff does takeoff. Estimating is Quick Bid, which is a separate purchase, and the supplier pricing network is eQuotes, which arrives through Quick Bid. The three together are a deep and genuinely proven pipeline. They are also three products, three line items and three things to keep in step.

Groundwork is one seat: measure, assemble, price, export, in the same window.

Where they beat us

Thirty years in the commercial interior trades is not nothing

OST has been in use since 1995 and it shows in the good ways as well as the dated ones: deep multi-condition takeoff, a proven plan overlay, and real strength in drywall and walls-and-ceilings work where its conditions model fits the trade exactly. Paired with Quick Bid and eQuotes, the full ConstructConnect workflow reaches further into procurement than we do, and its long-time users know every corner of it. If that is your pipeline and it is working, switching is a cost, not a saving.
