Is GCPay or Sitemark better?

Neither clearly leads. GCPay starts at On request and Sitemark at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, GCPay or Sitemark?

GCPay starts at On request and Sitemark at On request.

GCPay runs on Web. Sitemark runs on Web, iOS, Android.

What is GCPay best used for?

GCPay is most often used for a general contractor in a strict lien state that has been burned by a missing unconditional waiver and needs waiver status tied to each payment rather than filed in a shared drive, a contractor whose accounts payable team spends the first week of every month rekeying pay applications from pdf emails into sage or viewpoint, an owner-facing gc that must produce a clean audit trail of who was paid what and when, with insurance compliance evidence attached, a construction group standardising on autodesk construction cloud that wants payment application data in the same estate as the project record. Of those, a general contractor in a strict lien state that has been burned by a missing unconditional waiver and needs waiver status tied to each payment rather than filed in a shared drive and a contractor whose accounts payable team spends the first week of every month rekeying pay applications from pdf emails into sage or viewpoint are not what Sitemark is typically brought in for.

The short version

Each has a real cost: GCPay the subcontractor is a compelled user who did not choose the tool, so adoption friction and support load fall on the general contractor, and small trades with one bookkeeper resent every extra portal.; 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: GCPay covers Pay application workflow, Sitemark covers Construction progress tracking.

Where each one falls short

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

GCPay

The subcontractor is a compelled user who did not choose the tool, so adoption friction and support load fall on the general contractor, and small trades with one bookkeeper resent every extra portal.
Pricing is entirely quoted and keyed to annual subcontracted construction value, which means a contractor with a few very large subcontracts can pay far more than one with many small ones for identical functionality.
The ePayment fee structure is decided per general contractor, so a subcontractor cannot predict its cost of getting paid across clients and may be charged on one job and not another for the same work.
It is a payment and compliance system, not job costing; commitments still have to reconcile against the ERP, and integration gaps mean many contractors run a manual check anyway.
Autodesk acquired parent Payapps in 2024, and the strategic direction is convergence with Autodesk Construction Cloud, so buyers on Procore or a non-Autodesk stack should ask directly what the roadmap commitment to their platform is.

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

GCPay: Who pays for GCPay, the GC or the sub?

The general contractor pays the subscription. Subcontractor accounts are free. Only the optional ePayment and waiver exchange transaction fee can be passed to the subcontractor, and only with their acknowledgement.

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.

GCPay: How much is the ePayment fee?

It is a flat per-transaction fee, disclosed at the point the pay application is submitted. GCPay has published a $15 figure for the ePayments and waiver exchange service, and the GC decides who bears it.

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.

GCPay: Is GCPay owned by Autodesk?

Yes. Autodesk agreed to acquire Payapps, which trades as GCPay in North America and Payapps elsewhere, in January 2024.

Sitemark: Does it cover anything other than solar?

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

GCPay: Does it replace our construction accounting system?

No. It handles the application, approval and compliance workflow and then pushes approved payments into your ERP.

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.

GCPay: Can subcontractors export their own records?

Subcontractors can download their submitted applications and waivers, but the project record belongs to the general contractor's account, so a sub should keep its own copies rather than rely on continued portal access.

Sitemark: Where is the company based?

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