A trade group total can mix direct builder debts with subcontract debts

The group total does not identify who owes whom
Several trades compare unpaid amounts after a builder collapses. Some contracted directly with the builder, while others worked for those subcontractors. Before describing the sum as the builder's debt to the group, identify each contractual relationship. Sharing a project does not establish that every invoice is owed by the same legal entity.
Map each invoice to its actual customer
Use the accepted quote, order, contract and invoice to identify the parties. Show unresolved identity questions explicitly. Do not rewrite the customer field to match the company everyone is discussing. Where rights against another party may exist, ask for specific legal advice rather than assuming the group spreadsheet itself establishes them.
Keep the supporting records separate
Business.gov.au's record-keeping guidance includes sales, invoice and payment records. Retain each business's own documents and reconcile its account. The shared map should help explain relationships, while protecting information that members are not authorised to circulate. It should not replace individual claim documents or be submitted as if one combined figure automatically represents every member's legal position.

Consider a simple payment chain
Imagine the builder owes one contractor $100,000, and that contractor owes a supplier $60,000 for work contributing to the project. The group has identified two different liabilities, not necessarily $160,000 directly owed by the builder to those two members. Keep both debts visible and ask the adviser how the actual relationships and available processes affect each position.
Identify where interests may differ
Members may face different recovery routes or obligations to each other. Tell the proposed adviser about those connections before asking for a single group strategy. Do not pressure one member to disclose confidential advice or accept another member's position merely to keep the headline group total intact. Coordination should improve the factual picture rather than conceal conflicts within it.
Use a qualified description of the total
Distinguish direct claims, downstream exposure and unresolved relationships in group updates. Keep formal submissions within the relevant creditor process and obtain advice on each business's rights. The resulting picture may be more complex than a single large number, but it gives the group a sounder basis for advice and avoids presenting project-related exposure as a debt of one entity without supporting evidence.
