Retention Payments: Track Release Conditions and Expected Cash
Track retention payments in a register that separates the amount withheld, the condition for release, the supporting documents and the date you expect the money. Keep these balances distinct from ordinary overdue invoices. A forecast date is an estimate, not proof that payment is legally due: check the contract and the construction payment rules applying to that project.
What you’ll get from this guide: For small contractors: see which retention balances need documents, legal clarification or a change to the cash forecast.
Keep the retained amount visible after the job closes
The work can be finished while some of the payment remains conditional. If the job disappears from your operational list at handover, its retention balance can disappear from your weekly attention too.
Set up a separate schedule linked to the original contract and progress claims. It should explain why the money is withheld and what must happen next. This guide follows the contractor waiting to receive retention; it is not a statutory trust-account ledger for a business holding someone else's money.
The NSW Government describes cash retention as security withheld from subcontractor progress payments, including for defective work or late completion. Whether a particular amount can be withheld or must be released depends on the applicable rules and agreement.
Use separate dates for separate questions
Record the practical completion date with its certificate or other evidence, rather than a date someone remembers. Then use separate columns for:
- the release condition and relevant contract clause;
- the date that condition is expected to be met;
- any notice or claim deadline, with the source and person who checked it;
- the expected bank receipt date, plus the evidence behind that estimate.
Leave an unverified legal deadline marked not confirmed. Set a reminder to get the date checked. Don't use a guess as the final claim deadline.
Build a register from the withholding records
Start with each payment certificate or remittance showing a deduction. Record the original claim reference, amount withheld, releases already received, balance remaining, party holding it and any notified deduction or dispute. Link documents rather than relying on a notes field that says "see email".
Assumptions: Fictional contracts C-17 and C-18. AUD amounts are illustrative cash amounts, not statutory rates or recommended contract terms. Dates are forecast assumptions.
| Contract / retention balance | Release condition to verify | Evidence on file / missing | Expected receipt / uncertainty | Owner and next check |
|---|---|---|---|---|
| C-17: $5,000 withheld − $2,000 released = $3,000 | Remaining release under clause 14; recorded defects review completed | Completion certificate and earlier receipt saved; written release response outstanding | Week starting 21 Sep 2026 / uncertain until response checked | Alex: follow up release evidence on 14 Sep |
| C-18: $2,400 withheld; no release yet | Recorded defects review and acceptance requirements under clause 9 | Retention deduction verified; two defect items remain open | No confirmed receipt week / exclude from near-term base receipts | Priya: obtain rectification and review dates on 14 Sep |
| Total still recorded: $5,400 | Different conditions; do not treat as one due invoice | Reconcile each balance to certificates and receipts | Only $3,000 has an illustrative timing scenario | Review both records weekly |
Original ASBG fictional example. Use the assumptions above when replacing these figures with your own.
The register still shows $5,400 even though only $3,000 has an estimated near-term receipt. Keep the whole balance on the register even when you can't yet put a receipt date in the forecast.
Get the release questions checked before entering deadlines
Give a construction lawyer the contract, variations, progress claims, certificates and retention deductions. Ask for a written answer to the questions affecting this particular balance:
- Which release condition applies, and what evidence shows it has been met?
- Which notices or claims are needed, who must receive them and by when?
- Is there a retention trust arrangement relevant to this project, and which records should you request?
- Who should handle an unresolved defect, deduction or refusal to release money?
Keep the reply with the register, including the jurisdiction, source and date checked. Useful official starting points include QBCC's retentions guidance for Queensland and NSW's retention-money guidance. This worksheet does not set a default defects period, trust eligibility rule or claim deadline. Leave those fields unconfirmed until the actual project has been checked.
Show what a delayed release does to cash
This fictional fortnight starts with $12,000 in the bank. Ordinary receipts are $8,000 and planned payments are $21,000. C-17's possible $3,000 release changes the closing balance from a $1,000 shortfall to $2,000.
Assumptions: AUD. All other receipts and payments stay the same. These are scenarios, not a prediction that release will occur.
| Scenario | Opening cash | Ordinary receipts | Retention received | Payments | Closing cash |
|---|---|---|---|---|---|
| Release received | $12,000 | $8,000 | $3,000 | $21,000 | $2,000 |
| Release delayed | $12,000 | $8,000 | $0 | $21,000 | −$1,000 |
Original ASBG fictional example. Use the assumptions above when replacing these figures with your own.
Use both cases in your cash flow forecast. The late-customer payment stress test shows how to carry a delayed receipt through later weeks. Don't put the retained balance in ordinary invoice receipts and add it again as a separate retention receipt. If the release date remains uncertain, test the shortfall before committing the cash.
Review evidence before chasing payment
Each week, check new withholding, releases received, approaching document dates and unresolved defects or deductions. Save the response to a precise request: "Our schedule records $3,000 retained under C-17. Please confirm your recorded balance, the release conditions you consider outstanding and the supporting documents required."
An unanswered question or disputed condition needs assessment. It should not automatically become the standard overdue-invoice reminder sequence. Give your adviser the contract, claim history, notices and dated correspondence. The cash flow and getting paid hub covers the surrounding administrative tasks.
Next, compare agreed billing milestones with project spending.
Key takeaways
- Keep a retention schedule after the operational job has closed.
- Separate contract conditions, verified deadlines and expected cash dates.
- Reconcile withholding less releases to the balance still recorded.
- Test delayed receipts in the forecast, and obtain jurisdiction-specific advice before relying on legal entitlement or a claim deadline.
Where to get help
- QBCC: Retentions and securities explains Queensland's retention and notice framework.
- NSW Government: Retention money explains the NSW trust scheme.
- A construction lawyer in the project's jurisdiction can check release entitlement and claim dates. Your bookkeeper can maintain the schedule; your accountant should determine the ledger and tax treatment.
