WNDW vs Payapps.
Not alternatives. Complements.
Payapps is a collaborative progress claim platform used widely by Australian head contractors to standardise how subcontractor claims are submitted, assessed and approved. If your builder uses Payapps, you submit through Payapps. That isn't a choice you get to make.
These aren't alternatives.
Payapps solves the head contractor's problem.
Getting consistent, assessable claims from thirty subcontractors instead of thirty different spreadsheets. It handles Security of Payment timeframes, payment schedules and audit trails.
WNDW solves the subcontractor's problem.
Knowing what to claim in the first place.
The gap between those two is where most subbies lose money. Payapps gives you a form to fill in. It doesn't tell you that 412 of 1,010 openings on Tower 1 are installed, that eleven of them are subject to an approved variation, and what that adds up to against the schedule of rates. That number comes from your own records — which for most subbies means a spreadsheet reconstructed from photos, memory and a foreman's WhatsApp messages at the end of the month.
WNDW produces that number from what was actually signed off on site, then you submit it wherever the builder wants it.
Where Payapps is better.
It's what your builder uses
Nothing WNDW does removes the need to submit through the client's portal if that's the requirement.
Security of Payment workflow
Reminders, payment schedules and statutory timeframes handled at the approval end.
Assessment and approval
The builder-side workflow is the product, and WNDW has no equivalent because it isn't trying to.
Where WNDW fits.
Contemporaneous records
Sign-offs captured as the work happens, locked to the record so they can't be changed after the fact. When a claim is disputed the evidence already exists.
Claim built from completion
Openings, stages and rates produce the figure. Retention and practical completion / DLP release handled, variations tied to the same records.
Mobile and offline
Payapps is a desktop approval workflow. WNDW is a foreman on a scaffold with no signal.
The honest summary.
Use both.
WNDW is where the claim is built; Payapps is where it's delivered and assessed. If you're evaluating WNDW and already on Payapps, nothing changes about how you submit — only about how much reconstruction happens before you do.
See the difference yourself.
Bring your last claim. We'll walk through what it looks like when the record is built from day one, not reconstructed at the end of the month.
