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.; Topcon MAGNET mAGNET is built around Topcon and Sokkia hardware, so a firm running mixed instrument brands will not get the field workflows it expects and is better served by manufacturer-independent field software.
  • They diverge on capability: GCPay covers Pay application workflow, Topcon MAGNET covers MAGNET Field.
  • 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.

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.

Topcon MAGNET

  • MAGNET is built around Topcon and Sokkia hardware, so a firm running mixed instrument brands will not get the field workflows it expects and is better served by manufacturer-independent field software.
  • Topcon does not publish a rate card and sells through dealers, so two customers can pay materially different prices for the same licences depending on region and negotiation.
  • Cloud connectivity through MAGNET Enterprise is commonly bundled for the first year and then charged, which surprises firms that budgeted only for the licence.
  • Office capability is spread across modules and disciplines rather than sold as one product, so getting from data collection to machine control model preparation can require more than one purchase.
  • The office desktop software is Windows only and the wider line has been reorganised more than once, so buyers should confirm which specific product name their dealer is quoting and how long it will be supported.

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.

Topcon MAGNET: Does MAGNET work with Trimble or Leica instruments?

Not as a practical daily workflow. It exchanges standard file formats but the field software is designed for Topcon and Sokkia hardware.

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.

Topcon MAGNET: Is pricing published?

No. MAGNET is sold through Topcon dealers with quotes varying by region and configuration.

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.

Topcon MAGNET: Is the cloud service included?

Typically for a first year with a licence, then renewable as a paid subscription.

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.

Topcon MAGNET: Can I get my data out at project closeout?

Yes, through LandXML, DXF and standard survey exchange formats, though field-specific configuration does not transfer to a competitor.

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.
