Agency billing digest: track the handoff from invoice to cash
Payment links and follow-ups matter, but agency DSO reduction starts with measuring each step from approved work to cleared payment.
Compare tracked hours with the retainer’s pace halfway through the cycle, then decide what to change before the remaining budget is gone.
A retainer can look healthy at the start of a month and be nearly spent by the middle. The useful moment to catch that is before the remaining hours are already committed.
Run a mid-month retainer check against two measures: how much time the team has logged, and how much of the billing cycle has elapsed. Kato’s Pro plan includes time tracking and retainer management, with usage and remaining hours visible. Use those records as the starting point, then check the work behind the numbers before changing delivery plans.
Start with the retainer’s actual billing period. It may run from the first to the last day of a calendar month, or follow another agreed cycle. Use the included hours for that specific period, not a general monthly target or a figure carried over from another client.
In Kato, review the client’s retainer usage and remaining hours alongside its time-tracking data. If you manage several accounts, do this one retainer at a time. Mixing clients or cycles can make an agency time tracking review look more decisive than it is.
For a simple comparison, calculate:
For example, if a 40-hour retainer has used 27 hours at the halfway point, it has consumed 67.5% of its allowance while 50% of the cycle has elapsed. That is a signal to investigate, not proof that the account is out of control.
Before forecasting, inspect what the logged time represents. Look for work that belongs to a different client, duplicate or incomplete entries, and tasks that have shifted in priority. A large total may reflect an agreed launch or a short burst of approved work. It may also point to unplanned requests or repeated revisions.
Use the linked client and task context to connect time with the work in progress. Kato tasks can include owners, statuses, priorities, due dates, files, comments, and linked client records. That gives an operations manager a way to check whether the hours match current commitments rather than treating a number as a verdict.
Also check how the retainer agreement treats different kinds of work. Do not assume every internal activity, meeting, or revision is billable. If a time entry’s status under the agreement is unclear, confirm it with the account lead before using it to trigger a client conversation.
Ask what remains due in the cycle and who is expected to deliver it. A retainer running ahead of pace may still be manageable if the remaining tasks are small and well understood. A retainer near its limit with several substantial commitments outstanding needs attention now.
In Kato, review the client’s tasks and account activity for upcoming work, recent decisions, and follow-ups. Ask Kato about account activity or the next follow-up if a quick summary would help; check its answer against the workspace context and the agreed scope. Do not treat a summary as a replacement for validating the time entries or the contract.
A straight-line forecast can be a useful warning, but it is not a delivery plan. Work often arrives unevenly across a cycle. Use the actual remaining tasks, known deadlines, and team capacity to estimate whether the remaining hours will cover the agreed work. If the team cannot explain the forecast, mark the estimate as uncertain.
If the remaining work fits the allowance, keep the plan and set a date for another check. If capacity is tight, decide which action is appropriate before people continue absorbing extra work:
Make the decision explicit. Record who owns the next step, what work is changing, and what the client has approved. A useful audit ends with an action, not just a percentage. For the related payment side of the process, see this agency billing digest on tracking the handoff from invoice to cash.
Agree on when the account will be checked again. Review sooner if the team is using hours much faster than planned, a deadline is close, or the client has added work. Otherwise, keep the next check tied to the team’s normal operating rhythm.
The aim is not to keep every retainer exactly on a linear pace. It is to spot a mismatch while there is still time to reallocate capacity or reset expectations. A short, evidence-based mid-month retainer check gives the agency and client more options than an end-of-cycle surprise.
Payment links and follow-ups matter, but agency DSO reduction starts with measuring each step from approved work to cleared payment.
Close the work, reconcile time and billing, and preserve the account history before a client relationship ends.
