Accounting firm capacity planning: can your team take on more work?

Planning memo: “We have spare hours” is not enough reason to accept another client assignment. Those hours may belong to a junior preparer. Meanwhile, three files may need the same reviewer on Thursday. The team can have spare time overall but still lack time for the step needed to finish the work.

Capacity planning means checking whether the right people have enough time to finish future work. Timesheets help you estimate effort, but hours worked yesterday do not tell you who is free next week. Use this manual method with your practice-management records. You do not need a software score showing how much of the team's time is in use.

Decide who and which weeks to plan for

Start with a detailed plan for the next two weeks and a rough plan for the following month. For the next two weeks, name the person doing each task and its deadline. For the later weeks, use reasonable time ranges, expected new work and known absences. Planning every hour three months ahead adds paperwork without making the future certain.

Plan by person or skill group and by stage. Preparation, specialist work, review and client discussion are not interchangeable. A staff member who can assemble source documents may not be qualified to approve a complex adjustment. A partner's availability after the delivery date cannot solve a review shortage before it.

Use the same measure throughout: hours still needed to finish each stage. For a task already started, do not use the original estimate for the whole task. Say whether the remaining hours include questions, corrections and discussions with the client. These take time even when you do not bill for them separately.

Also distinguish an external statutory deadline from an internal target. Both matter, but moving an internal preparation date may be possible where changing the filing deadline is not.

Calculate availability before assigning the load

For each person, begin with scheduled working hours. Subtract approved leave, fixed internal commitments and other time that is genuinely unavailable for the planned client stages. Avoid assuming that a 37.5-hour workweek offers 37.5 hours of uninterrupted client preparation.

Then reserve a clearly stated allowance for unpredictable questions, short corrections and interruptions. This is a planning choice, not a required industry benchmark. Set it using the practice's own experience and revisit it. Hiding that allowance inside every estimate and subtracting it again from capacity understates availability twice.

Keep available hours separate from fee budgets. A fixed-fee assignment may pay well but still need review hours that nobody has. Unused money in a budget does not give an employee more time. If staff work for several clients, do not promise the same hours in several plans.

Bookwits budgets can help you compare allowed time with actual hours from timesheets. Use that comparison to improve estimates that are often too low. This does not mean Bookwits calculates future availability after leave or automatically chooses the best person for each task.

A worked week with an apparent surplus

Consider a fictional team with two preparers and one reviewer. These are illustrative planning assumptions, not staffing standards. All figures below are hours for one week after known commitments have been identified.

Weekly availability and remaining assigned work

Role	Scheduled	Known unavailable	Uncertainty allowance	Available	Assigned
Preparer A	37.5	7.5	3	27	24
Preparer B	37.5	5.5	3	29	25
Reviewer	30	12	3	15	19

The team has 71 available hours: 27 + 29 + 15. Assigned work takes 68 hours: 24 + 25 + 19. That leaves three hours overall, but the roles tell a different story. The preparers have seven spare hours. The reviewer is short by four hours. Spare preparation hours cannot replace qualified review hours.

Check when those hours are available, too. If preparation finishes Friday afternoon, the reviewer's 15 free hours earlier in the week may not help. Each person needs time after the previous stage is ready and before the deadline. Weekly totals help you spot problems. They do not prove the schedule will work.

A proposed new client needs five preparation hours and two review hours in that same week. Accepting it would increase the review shortfall to six hours. The sensible next discussion concerns a different start date, qualified cover or a changed commitment—not who can type faster.

Keep track of work waiting for documents

Missing documents can make a queue look quiet. They do not remove the underlying obligation. Maintain a distinct list of work waiting for the client, another provider or an internal decision. Give each item a probable readiness window and a responsible follow-up person.

When arrival dates are uncertain, consider a few possible outcomes. What if three late clients send records on the same day? Which deadlines are at risk if a specialist is away? Do not treat every waiting file as work you can start now. Still, allow for those files becoming ready when you discuss future weeks.

Record the next action specifically. “Waiting” with no owner allows deadlines to age invisibly. “Client to provide signed approval; engagement lead to follow up Wednesday; reviewer needed for one hour after receipt” connects the missing input with its capacity effect.

Bookwits tasks, due dates, assignees and comments can help organize these actions. Your firm still decides when work is ready, estimates the hours left and updates the plan when new information arrives.

Rebalance using decisions, not a single percentage

Respond to the constrained stage first. Can a qualified colleague review a defined portion? Can a preparer resolve straightforward questions before sending the file? Can a delivery conversation move with the client's agreement, while protected statutory work remains on time? Each option has different quality and relationship consequences.

Do not assign work solely to the person with the lowest recorded hours. Consider competence, continuity, onboarding effort and the recipient's existing commitments. Reassignment can consume explanation time for both people. Include that cost rather than presenting a transfer as free capacity.

If you cannot solve the shortage responsibly, tell the decision-maker early. List the work affected, the skills needed, the hours missing and the dates. Then explain the options. Overtime, outside help, hiring, changes to the agreed work and later start dates all have costs and limits. A schedule must not assume these choices have been approved.

Aim for credible promises, not universal maximum utilization. A plan with no room for an urgent correction is brittle even when its arithmetic is immaculate.

Update the plan each week

Run a brief weekly review of ready work, waiting work, review congestion and new commitments. Compare completed stages with their estimates. Separate a genuinely underestimated task from a task expanded by new scope; otherwise next month's estimates inherit the wrong lesson.

Use time records and budget comparisons to improve the assumptions, not to punish staff for documenting real work. Missing time data makes an apparently profitable or underloaded file difficult to interpret. Where access is relevant, the Bookwits Budget guide documents Owner and Admin access; do not assume every team member sees the same financial context.

Finish by naming who will handle each short-staffed stage. Decide what to tell clients and which new assignments can start safely. Bookwits can help record and coordinate the work. Managers still have to judge whether the plan is realistic. A dashboard cannot guarantee it.
