The short version

  • Each has a real cost: Siteline it serves subcontractors only, so a general contractor evaluating it is looking at the wrong side of the transaction entirely.; 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: Siteline covers Pay application generation, 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.

Siteline

  • A trade contractor whose billing team rebuilds the same pay application in four different general contractor formats each monthnot Sitemark
  • A subcontractor losing a billing cycle to rejected applications over missing lien waiversnot Sitemark
  • A finance director trying to forecast collections across dozens of general contractors and retention balancesnot Sitemark
  • A growing subcontractor whose billing process depends entirely on one person and a spreadsheetnot 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 Siteline
  • An asset owner accepting a plant at provisional acceptance who needs documented evidence that what was built matches the issued design before signingnot Siteline
  • An operations team running annual thermographic inspection across a portfolio, wanting defects mapped to module positions so a technician goes straight to the faultnot Siteline
  • A developer comparing defect and underperformance rates across contractors and module suppliers to inform the next procurement roundnot Siteline

Where each one falls short

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

Siteline

  • It serves subcontractors only, so a general contractor evaluating it is looking at the wrong side of the transaction entirely.
  • It does not do job costing, project management or payroll, so it is an addition to your systems rather than a consolidation of them.
  • Value depends on a clean integration to your construction accounting system, and contractors with heavily customised or elderly installations should confirm the connection before signing.
  • General contractor portals and billing formats change without warning, and although the vendor absorbs that maintenance you still feel it as occasional friction in a month-end window with no slack.
  • The billing team has to adopt it fully in the first month-end or they revert to spreadsheets under deadline pressure, which makes the implementation timing more delicate than the software suggests.

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

Siteline: Does it replace our accounting system?

No. It reads from Sage 300 CRE, Vista, Foundation and similar systems and handles the billing workflow those systems handle poorly.

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.

Siteline: What should we measure in a trial?

Days sales outstanding and the number of rejected or delayed pay applications. The case is about cash timing, not headcount.

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.

Siteline: Is it useful for general contractors?

No. It is built for the party submitting pay applications, not the party receiving them.

Sitemark: Does it cover anything other than solar?

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

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.
