The short version

  • Each has a real cost: On-Screen Takeoff perpetual licensing is no longer offered on current releases, so long-standing users who paid once now face a recurring annual cost they never budgeted, and staying on an old version means no support for newer PDF formats; Sitemark it only does solar, so a mixed renewables portfolio still needs a second platform for wind, storage and substations, and the consolidation argument for buying it collapses.
  • They diverge on capability: On-Screen Takeoff covers Drawing takeoff, Sitemark covers Construction progress tracking.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

On-Screen Takeoff

  • A drywall contractor measuring wall area and openings across a 300 sheet set where manual takeoff would take a weeknot Sitemark
  • An estimator who receives a late addendum and needs to know which rooms changed rather than re-measuring the whole floornot Sitemark
  • A flooring subcontractor maintaining reusable conditions with waste factors so quantities and material orders stay consistent between estimatorsnot Sitemark
  • A trade contractor that wants takeoff quantities split by phase so progress billing matches the way work is actually releasednot Sitemark

Sitemark

  • An EPC contractor on a multi-hundred-megawatt ground-mount plant that must report weekly installed counts to a lender and cannot do it by walking the rowsnot On-Screen Takeoff
  • An asset owner accepting a plant at provisional acceptance who needs documented evidence that what was built matches the issued design before signingnot On-Screen Takeoff
  • An operations team running annual thermographic inspection across a portfolio, wanting defects mapped to module positions so a technician goes straight to the faultnot On-Screen Takeoff
  • A developer comparing defect and underperformance rates across contractors and module suppliers to inform the next procurement roundnot On-Screen Takeoff

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

On-Screen Takeoff

  • Perpetual licensing is no longer offered on current releases, so long-standing users who paid once now face a recurring annual cost they never budgeted, and staying on an old version means no support for newer PDF formats
  • ConstructConnect does not publish a price, and the product is increasingly sold inside a bundle with lead data and estimating, so buyers who want takeoff alone often find the quote priced around a package they do not need
  • It is Windows desktop only, with no macOS version and no meaningful browser or tablet workflow, which rules it out for firms standardised on Apple hardware
  • The interface has changed little in years and estimators coming from browser-based tools find the condition setup and layer management slow to learn, so onboarding a new estimator takes longer than the software cost would suggest
  • ConstructConnect sells lead data, takeoff and estimating as a portfolio and has consolidated several acquired products, so a buyer committing to On-Screen Takeoff should ask directly where it sits against the newer cloud takeoff products in the same portfolio

Sitemark

  • It only does solar, so a mixed renewables portfolio still needs a second platform for wind, storage and substations, and the consolidation argument for buying it collapses.
  • Pricing is quoted on site count and unpublished variables, which penalises owners of many small distributed assets relative to one operator of a single large plant with the same total capacity.
  • You still need someone to fly the site, and Sitemark does not remove the drone operator cost, permits or airspace constraints; it monetises the data after the flight.
  • Automated progress counting depends on a clean, current design layout, and on projects where the layout changes weekly the comparison generates false deviations that erode trust in the numbers.
  • Thermographic defect detection needs the plant producing at sufficient irradiance, so inspection windows in northern latitudes are narrow and a missed window pushes findings into the next season.

Answered from the vendors’ own pages

On-Screen Takeoff: Can I still buy a perpetual licence?

No. Current releases are annual subscription. Older perpetual licences continue to run but do not receive updates.

Sitemark: Is Sitemark priced per megawatt?

No. Sitemark states pricing is based on number of sites and other variables. Ask explicitly how a portfolio of small sites is treated, because per-site pricing is unkind to distributed assets.

On-Screen Takeoff: Is it sold separately from Quick Bid?

It can be, but ConstructConnect increasingly quotes it as part of a takeoff and estimating package. Ask explicitly for standalone pricing if that is what you want.

Sitemark: Do we have to use Sitemark drone pilots?

No. It accepts data from third-party drone operators, which lets you keep an existing flight contractor.

On-Screen Takeoff: Does it run on a Mac?

Not natively. It is a Windows application and Mac users run it under virtualisation, which is unsupported in practice for large drawing sets.

Sitemark: Does it cover anything other than solar?

No. It is built specifically around solar plant structures and defect types.

On-Screen Takeoff: Will it read a scanned drawing?

Yes, but measurement accuracy on a scanned raster set depends entirely on the scan quality and on setting scale from a verified dimension.

Sitemark: Can we export our data?

Yes, orthomosaics, defect lists and reports export. Confirm the format and whether historical inspections remain accessible after a subscription lapses.

Sitemark: Where is the company based?

Leuven, Belgium, with customers across Europe, the Middle East, Asia and the Americas.
