The short version

  • Each has a real cost: 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.; Trimble Pay the Flashtract name is being retired in favour of Trimble Pay, so existing documentation, comparison articles and integration listings are split across two names and buyers should confirm which contract entity and which support channel applies
  • They diverge on capability: Topcon MAGNET covers MAGNET Field, Trimble Pay covers Automated pay applications.
  • 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.

Topcon MAGNET

  • A civil contractor running Topcon grade control that needs design models prepared and pushed to machines from one environmentnot Trimble Pay
  • A survey crew doing construction layout with Topcon total stations and wanting field data to reach the office without a memory cardnot Trimble Pay
  • An earthworks estimator producing takeoff quantities and mass haul plans from engineering drawingsnot Trimble Pay
  • A firm standardising on one manufacturer end to end to reduce the number of software packages its crews have to learnnot Trimble Pay

Trimble Pay

  • A general contractor whose accounts payable team rejects a third of subcontractor billings each month for arithmetic or form errorsnot Topcon MAGNET
  • A contractor working across several states that needs the right statutory waiver language selected automatically rather than from a shared template foldernot Topcon MAGNET
  • A company that has been quoted Oracle Textura and wants to compare the total cost when the fee falls on the contractor rather than on the tradesnot Topcon MAGNET
  • A contractor that needs the unconditional waiver to be released only after funds clear, so it is not holding a waiver that a court would treat as ineffectivenot Topcon MAGNET

Where each one falls short

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

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.

Trimble Pay

  • The Flashtract name is being retired in favour of Trimble Pay, so existing documentation, comparison articles and integration listings are split across two names and buyers should confirm which contract entity and which support channel applies
  • Pricing is not published, and because it is bought by the general contractor rather than charged to subcontractors, the whole cost lands in one budget line rather than being distributed across the supply chain
  • It is billing and compliance only, so a contractor still needs a project management system for drawings and RFIs and a construction ERP for the general ledger, and the value depends heavily on the quality of those two integrations
  • Lien waiver correctness is a legal question, and the system generates forms rather than giving advice, so a contractor operating in an unusual jurisdiction still needs counsel to confirm the templates match current statute
  • Under Trimble the product now sits alongside other Trimble construction financial assets, and buyers signing multi-year terms should ask directly how it is positioned against Viewpoint and the rest of the Trimble construction portfolio

Answered from the vendors’ own pages

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.

Trimble Pay: Is Flashtract still sold under that name?

No. Trimble acquired Flashtract and now sells it as Trimble Pay. The flashtract.com content redirects into the Trimble product pages.

Topcon MAGNET: Is pricing published?

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

Trimble Pay: Do subcontractors pay to use it?

No. The general contractor buys it. This is the main commercial difference from Oracle Textura, where subcontractors are billed a percentage of their contract value per project.

Topcon MAGNET: Is the cloud service included?

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

Trimble Pay: Does it replace my accounting system?

No. It generates and approves the billing and the waivers, then posts to your construction ERP. You still need the ledger.

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.

Trimble Pay: Does it handle lower-tier subcontractors?

Yes, it tracks sub-tier amounts and sworn statements against the prime commitment, which is the usual source of surprise lien exposure.
