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.; 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.
  • They diverge on capability: GCPay covers Pay application workflow, RIB CostX covers 2D drawing takeoff.
  • 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.

GCPay

  • 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 drivenot RIB CostX
  • A contractor whose accounts payable team spends the first week of every month rekeying pay applications from PDF emails into Sage or Viewpointnot RIB CostX
  • An owner-facing GC that must produce a clean audit trail of who was paid what and when, with insurance compliance evidence attachednot RIB CostX
  • A construction group standardising on Autodesk Construction Cloud that wants payment application data in the same estate as the project recordnot RIB CostX

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 GCPay
  • A contractor tendering a job where the client reissues drawings mid-tender, needing revision comparison so only changed areas are remeasurednot GCPay
  • An estimating department moving from paper and Excel to model-based measurement while keeping the same rate library and bill structurenot GCPay
  • A cost consultant producing early-stage elemental cost plans from partial models, then refining the same workbook as design detail arrivesnot GCPay

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
