Need to submit a Pay App to S3 Partners?

Payment applications generally include the application for payment form and a continuation sheet (which includes a schedule of values and change orders). Depending on the situation, you may also include backup documents like materials receipts and invoices, payroll wage reports, and lien waivers.

It's a lot to keep straight, and it's further complicated by most GCs requiring their own custom payment application forms, rather than standard AIA templates. Fortunately, Siteline has more than 8,000 forms from over 6,000 GCs—in our system. Our software streamlines the entire monthly billing workflow, ensuring you submit the perfect pay apps on time, every time, which gets your invoices paid about three weeks faster.Want to see for yourself?
