The short version

  • Each has a real cost: RIB CostX pricing is not published anywhere and is quoted per package and per seat through regional resellers, so two firms of similar size routinely pay materially different rates for the same configuration.; 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: RIB CostX covers 2D drawing takeoff, 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.

RIB CostX

  • A quantity surveying practice that must issue a formatted bill of quantities under NRM or SMM7 and cannot do so from a generic takeoff toolnot Trimble Pay
  • A contractor tendering a job where the client reissues drawings mid-tender, needing revision comparison so only changed areas are remeasurednot Trimble Pay
  • An estimating department moving from paper and Excel to model-based measurement while keeping the same rate library and bill structurenot Trimble Pay
  • A cost consultant producing early-stage elemental cost plans from partial models, then refining the same workbook as design detail arrivesnot Trimble Pay

Trimble Pay

  • A general contractor whose accounts payable team rejects a third of subcontractor billings each month for arithmetic or form errorsnot RIB CostX
  • A contractor working across several states that needs the right statutory waiver language selected automatically rather than from a shared template foldernot RIB CostX
  • 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 RIB CostX
  • 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 RIB CostX

Where each one falls short

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

RIB CostX

  • Pricing is not published anywhere and is quoted per package and per seat through regional resellers, so two firms of similar size routinely pay materially different rates for the same configuration.
  • It is Windows desktop software with heavy graphics demands; there is no meaningful macOS or browser option, which rules it out for practices standardised on Apple hardware.
  • The learning curve is steep enough that firms typically budget formal training, and an estimator productive in a rival tool takes weeks rather than days to reach the same output here.
  • RIB is owned by Schneider Electric, whose strategic interest is the wider RIB construction cloud, so a buyer choosing CostX today is betting on continued investment in a desktop estimating product inside a group focused elsewhere.
  • BIM takeoff is only as good as the model, and on projects where the model is modelled for coordination rather than measurement the automatic quantities need enough manual checking that the time saving largely disappears.

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

RIB CostX: How much does RIB CostX cost?

RIB does not publish prices. It is quoted per package (Quantify, Core or Complete) and per seat, usually through a regional reseller.

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.

RIB CostX: Is a perpetual licence available?

RIB has historically offered both perpetual and subscription licensing, with subscription now the default push. Ask explicitly, because the perpetual option is not advertised.

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.

RIB CostX: Does it do BIM takeoff or just 2D?

Both. Complete handles IFC and Revit models; Quantify and Core differ in workbook capability rather than measurement.

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.

RIB CostX: Who is it for?

Quantity surveyors and estimators in markets that use bills of quantities: UK, Ireland, Australia, New Zealand, the Middle East and South Africa above all.

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.

RIB CostX: Can we open estimates without a licence?

A free CostX Viewer lets others open and inspect measured drawings and workbooks without a full seat.
