Work can be finished without being ready to invoice. A timesheet may be waiting for approval, a purchase order may be missing, or a fixed-fee milestone may not yet have been accepted.
An unbilled-time review helps you separate legitimate waiting from avoidable delay. The goal is to understand what happens next for every meaningful balance, not to invoice every recorded hour automatically.
Define what the report is showing
Unbilled time generally means recorded time that has not been included in an invoice. The exact report behavior depends on the system and billing method. Check whether it includes unapproved entries, non-billable work, fixed-fee projects and time outside the selected date range.
Do not confuse unbilled time with an unpaid invoice. The first is a work-to-billing issue. The second is a collections issue. Nor should a report’s estimated billable value automatically be treated as earned revenue or an overdue receivable.
For hourly work, a useful starting estimate is eligible hours multiplied by the applicable agreed rate. Discounts, caps and other contract terms may change the amount you can charge.
Give each balance a status and an owner
A useful review distinguishes five situations:
| Status | What it means | Next action |
|---|---|---|
| Ready to invoice | Required approvals and billing conditions are satisfied | Add to the next agreed billing run |
| Approval needed | Time or expenses are awaiting review | Assign the approver and due date |
| Billing condition pending | A milestone, purchase order or other requirement is outstanding | Confirm the missing condition and owner |
| Clarification needed | Scope, rate or entry details need checking | Resolve against the agreement and delivery record |
| Intentionally not invoiced | Work is included in a fee, written off or non-chargeable | Record the reason using the appropriate workflow |
The last category matters. Otherwise, old balances can keep resurfacing because nobody has documented why they will not become a separate invoice.
Work through an example
Imagine an hourly project with 24 unbilled hours at an agreed $150 rate. Its potential billing value is $3,600 before adjustments.
Twelve hours are approved and eligible for the next invoice. Eight are waiting for the project lead’s review. Four describe additional work that the client has not yet authorized for charging.
The immediate invoice-ready amount is $1,800, not $3,600. The approval queue represents another $1,200 if approved and eligible. The remaining $600 is a commercial question to resolve, not an amount to quietly add to an invoice.
For a fixed-fee project, the same 24 hours help explain delivery cost. They do not necessarily create any incremental invoice value. Use the project’s billing schedule to determine the next charge.
Age the work against its billing rule
A simple age report based on work date can identify forgotten entries, but it can also flag perfectly normal milestone work. Pair work age with the date the work became eligible for billing.
For example, six-week-old time attached to a milestone accepted yesterday is different from six-week-old approved hourly work that missed two invoice runs. Both deserve visibility; only the second obviously points to a billing delay.
Set review thresholds around your own cadence. A weekly billing business may investigate a missed week. A monthly billing business should check readiness before month-end and investigate items that miss that run.
Run the review in a repeatable order
First, check whether recent time has been submitted. Missing time cannot appear in an unbilled report. Next, resolve approvals and incomplete descriptions. Then group the remaining balance by client and billing condition.
For every exception, record an owner, next action and review date. At the following review, inspect unresolved actions before adding new ones. A growing report without follow-through is only a more detailed backlog.
Do not delete time to make the report smaller. Preserve the delivery record and use the appropriate correction, non-billable classification or write-off process with a reason.
Time Trakkr’s uninvoiced reporting and approval workflow can support this check. Connect it to your timesheet approval process and invoicing workflow so the same work moves through both cleanly.
Common questions
Is all unbilled time a problem?
No. Some work is waiting for an agreed billing date or included in a fixed fee. The problem is an unexplained balance without a next action.
Who should own the review?
Finance or operations can coordinate it, but project leads need to resolve delivery and scope questions. Give each exception one accountable owner rather than making the whole team responsible.
