  • They diverge on capability: GCPay covers Pay application workflow, Kahua covers Project management.

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.

Kahua

  • No standard pricing tiers published; all pricing is custom and quote-based
  • Pricing varies by organization type, program or construction scale, selected package, and deployment environment
  • Implementation costs for data migration, integrations, training, and configuration scoped separately and included in quote

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.

Kahua: How much does Kahua cost?

Kahua does not publish standard pricing. Costs vary by organization type (Owners/Program Managers, General Contractors, Specialty Contractors), program scale, selected package, deployment environment, and implementation requirements. Customers must request pricing quotes.

Source
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.

Kahua: What package options does Kahua offer?

Kahua offers three main package categories: Owners and Program Managers, General Contractors, and Specialty Contractors. Additional specialty apps and suites including capital planning, analytics, asset management, and safety can extend the base solution.

Source
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.

Kahua: Are implementation and integration costs included in Kahua pricing?

Implementation details including data migration, integrations, training, and configuration are scoped based on requirements and clearly identified in the custom quote provided.

Source
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.

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.
