The developer (& lender/project manager) will login to IPEX with each new progress claim received & perform 2 quick checks:

1. Has each subcontractor linked to the last claim received payment?
2. Does the amount received (percentage paid against contract value) by each subcontractor broadly line up with work completed % on the last claim?

IPEX doesn’t change builder obligations under industry-standard agreements, it simply provides a range of tools to ensure that they’re honouring them.
