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.; Siteline it serves subcontractors only, so a general contractor evaluating it is looking at the wrong side of the transaction entirely.
  • They diverge on capability: GCPay covers Pay application workflow, Siteline covers Pay application generation.
  • Prices and features above were last checked on 1 September 2026.

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.

Siteline

  • It serves subcontractors only, so a general contractor evaluating it is looking at the wrong side of the transaction entirely.
  • It does not do job costing, project management or payroll, so it is an addition to your systems rather than a consolidation of them.
  • Value depends on a clean integration to your construction accounting system, and contractors with heavily customised or elderly installations should confirm the connection before signing.
  • General contractor portals and billing formats change without warning, and although the vendor absorbs that maintenance you still feel it as occasional friction in a month-end window with no slack.
  • The billing team has to adopt it fully in the first month-end or they revert to spreadsheets under deadline pressure, which makes the implementation timing more delicate than the software suggests.

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.

Siteline: Does it replace our accounting system?

No. It reads from Sage 300 CRE, Vista, Foundation and similar systems and handles the billing workflow those systems handle poorly.

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.

Siteline: What should we measure in a trial?

Days sales outstanding and the number of rejected or delayed pay applications. The case is about cash timing, not headcount.

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.

Siteline: Is it useful for general contractors?

No. It is built for the party submitting pay applications, not the party receiving them.

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.
