What is IPEX?
IPEX is an Australian online payment platform that secures funds intended for a project, protecting developers and subcontractors in the event of builder insolvency.
IPEX software integrates with a dedicated construction project bank account to ensure that progress payments are used only to pay approved subcontractors and suppliers linked to that specific project. IPEX provides developers with visibility over who has been paid and when, without sharing a builders’ commercially sensitive information.
Whilst IPEX protects developer and subcontractor payments, it also helps financially secure builders to validate their money management practices, differentiating their bid from competitors in the process.
Projects
Process under IPEX
There is no change to subcontractor claim process, builder claim process or QS assessment / approval process:
- Approved progress payments are paid into the builders’ IPEX account rather than their standard operational account
- The builder will receive their entitlements (prelims/margin/direct costs) plus those of any payees not required to be paid via IPEX (if any) via the agreed method, with the balance set aside for subcontractor/supplier payments
- The builder can pay onboarded subcontractors/suppliers/consultants whenever required by generating an ABA file via their accounting software. The ABA file is uploaded into IPEX; provided all payees contained within the ABA file have been onboarded to the project (and BSB/Account Number matches that entities info), payments are processed as they normally would be & remittance sent to each
- Subcontractor retention monies can also be held within IPEX
The developer (& lender/project manager) will login to IPEX with each new progress claim received & perform 2 quick checks:
- Has each subcontractor linked to the last claim received payment?
- 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.
