By The firms that survive busy season calmly decide what to hand off before the work arrives. The simplest plan is to measure your overflow in hours in November, choose the tasks that can leave the building, test a partner on a small batch, and have the arrangement running by early December. Waiting until the backlog is already visible in January leaves no time to test anything.
This guide gives you a practical way to do that. It uses your own numbers, so nothing here depends on a statistic you cannot check.
Step 1: Measure the overflow, not the whole workload
Overflow is the work your team cannot finish at normal hours in the weeks before filing deadlines. To size it:
- List every client that needs write-up bookkeeping, payroll tax work or sales tax prep in the next four months.
- For each client, write down the hours the work took last year, or your best estimate if it is new.
- Add up the hours by week. Compare the weekly total with the hours your team can actually deliver.
- The gap in the worst weeks is your overflow.
Worked example (illustration only): a firm has 40 write-up clients. Each takes about 3 hours a month, so the base load is 120 hours a month. Two staff deliver about 110 hours a month of that work after tax-return work takes its share. The firm is about 10 hours short each month, and the shortfall gets worse as return deadlines crowd out bookkeeping. The point is not these numbers. The point is that you can see the gap in hours and decide what to do about it.
Step 2: Decide which work can leave the building
Not everything should be handed off. A useful test is whether the task is routine and repeatable, or depends on your firm’s judgment about a client.
| Usually safe to hand off | Usually stays with the firm |
|---|---|
| Monthly bank and card reconciliation | Client relationships and advice |
| Transaction categorization in your chart of accounts | Final review and sign-off |
| Catch-up of unreconciled prior months | Tax positions and strategy |
| Payroll tax filing prep for standard clients | Anything needing your judgment on one client’s facts |
Hand off the first column and keep the second. That is also what keeps your name on the work and your review as the final control.
Step 3: Pick the clients for a first batch
Choose up to three standard clients, meaning ordinary monthly volume, a small number of bank accounts and one state. Avoid your most complex client for the first test. A good first batch is one you can check against your own results, such as a month your team has already closed.
Step 4: Set the hand-off rules before the work starts
Write down five things before anyone gets access:
- Access: read-only or limited roles in the client’s software, never shared passwords.
- Confidentiality: a signed agreement covering everyone who touches client data.
- Deliverables: reconciliations, schedules and review-ready books in your software, in the format you use.
- Turnaround: a clear number of working days from the moment your data is complete.
- Review: who on your team signs off before anything goes to the client.
If the partner is outside the US, add the notice and consent steps described in offshore bookkeeping for US CPA firms.
Step 5: Test on a small batch, then decide
Run the first batch and judge it on three things: accuracy against your own check, turnaround against what was promised, and how much of your review time it cost. If the review time is low and the accuracy is high, expand. If not, you found out on three clients and not thirty. RazaPro’s pilot is built for exactly this: it is free on up to 3 standard clients, with delivery in 5 to 7 working days once we have complete data.

A simple calendar
| When | What to do |
|---|---|
| November | Measure overflow. Choose the tasks and the first three clients. |
| Early December | Sign the confidentiality agreement. Start the first batch. |
| Mid December | Review the batch. Decide whether to expand. |
| January | Run at full capacity with the arrangement already tested. |

Does a plan like this only matter during busy season?
No. Firms that keep a partner running all year avoid the cycle of hiring temporary help every winter and losing it in spring, and client books stay current between deadlines. If you want to test it on a few clients before January, book a free consultation.
Common questions
When should a CPA firm line up busy season help?
In November. Measure the overflow, choose the tasks, test a partner on a small batch in early December, and have it running before January.
How do you size busy season overflow?
List the clients that need write-up, payroll tax or sales tax work, estimate the hours each takes, add them by week and compare with the hours your team can deliver. The gap in the worst weeks is your overflow.
What work can a CPA firm hand off during busy season?
Routine, repeatable work such as monthly reconciliations, transaction categorization, catch-up of prior months and standard payroll tax prep. Client advice, tax positions and final sign-off stay with the firm.
