Retention can make a job look paid on the invoice list while part of the cash remains conditional or scheduled for later. The risk is not only the amount: it is losing track of the contract basis, release condition, evidence and next action until the business needs the cash.
There is no universal release date that applies to every construction job. Use the signed terms and the facts of the job. This guide is a record-and-forecast approach, not a legal interpretation of a retention clause.
Keep a contract-specific record
For every retention, record the job, customer/contract party, contract reference, gross amount/currency basis, retention amount, relevant milestone, stated release condition, expected date, actual receipts and the person responsible for follow-up. Attach or link the evidence instead of relying on a note that says “due soon”.
Forecast cash conservatively
In the cash-flow forecast, do not treat retention as available working cash simply because an application has been raised. Show it separately with an evidence-based expected date and a confidence/status label. If the date is uncertain, leave it uncertain rather than making the forecast look smoother.
Review at each milestone
- Has the work reached the contractual milestone being relied on?
- Is the supporting evidence complete and stored with the job?
- Has the application/invoice stated the retention correctly?
- Is a defect, dispute or certification issue changing the expected date?
- What is the next collection action and who owns it?
The Construction Retention Register offers a practical working structure. Use it alongside the 13-Week Cash-Flow Forecast so timing assumptions are visible at the owner review.
