How to scope a bookkeeping retainer by workload

Begin with a representative month and an opening-balance check

Ask for an authorized sample of bank/credit-card statements, the current chart of accounts, the latest closed balance sheet, unreconciled transactions and existing accounting policies. Keep data access distinct from approval to move money. Record whether documents are complete and whether opening balances tie; a clean import screen can coexist with unresolved prior-period balances.

Count transaction families and exceptions rather than every feed row as equal work. Automated recurring expenses take a different process from split receipts, duplicate transfers, missing receipts or commingled personal spending. Ask which reporting questions must be answered and who will review them. Exclude tax filing/advice, audit/assurance, legal work, payroll processing, inventory costing and payment execution from this service unless a separately qualified/scoped service is arranged.

Turn the proposed scope into a timed task estimate

The example has 220.0 monthly transactions across 4.0 accounts. Its 8.0 delivery hours match the case core envelope, with 1.0 additional reviewer hour. These figures describe a proposed test file, not an observed customer. A month with fewer transactions may need more work if statements are missing or opening balances are unreliable.

Time the whole workflow, including handoffs and client questions. Record requested, active and elapsed time separately. A three-day document wait consumes little continuous staff time but can block a close and concentrate work at the deadline. Keep a fixed response window and explain what happens when the required documents arrive later; do not promise the same completion date regardless of readiness.

Price the deliverable hours and the reviewer

The case’s $28.00 paid-hour wage becomes $46.40 per usable delivery hour after 16.0% burden and the 70.0% usability assumption. Eight delivery hours, one owner review hour and client tools cost $411.20 before collection fees and write-off. BLS supports only a national wage comparison, while the chosen wage and hours remain case inputs. Wage scope; Employer tax components

For an illustrative 30.0% workload margin, divide that cost by one less target margin, processing and expected bad-debt shares. The computed price floor is $613.73. The core case fee of $650 leaves $219.30 workload margin under the same steady-collection assumptions. This target is an article choice, not an industry standard, and it does not pay the company’s entire idle roster or owner administration twice.

If delivery grows to 14.0 hours and review to 2.0, the same fee produces −$84.10 workload margin. Restoring the same target would require $1,066.57 at that workload. Reprice from measured causes, narrow the work or change the process; do not label the overrun profitable merely because cash arrived this month.

Write the envelope so both sides can apply it

State included accounts, transaction definition, normal document condition, reporting outputs, due dates, client duties, reviewer process and turnaround measured from a ready file. Describe which exception work remains included and what needs an extra estimate. Separate historical cleanup from a current-month retainer. Name the approved access method, authorized contacts, retention/return arrangements and engagement-end handoff.

Set a practical review trigger such as repeated scope overruns or newly discovered inventory/multi-entity complexity. The trigger starts a conversation and revised written scope; it does not automatically authorize an uncapped invoice. A vendor’s expenses-based tiering is a useful commercial comparison, but this article prices workload. Intuit separately defines cleanup and recurring work and waits for supporting documents before cleanup begins. Why readiness belongs in the scope

Check the quoted client against the whole close calendar

One client can have a positive allocation margin while the firm loses cash. The case pays staff in half-FTE steps and pays the owner’s whole month. Retainers, onboarding and cleanup share usable delivery hours, while review has its own ceiling. Before accepting the quoted client, insert its actual tasks into the close calendar and identify the next staffing step.

Track billed versus collected fees as separate measures. The base assumes current collection of 90.0% and a following-month receivable tail, not perfect cash realization. A retainer should specify invoice, due date, failed-payment follow-up and the scope of a permitted service pause; do not treat client records as collateral or silently continue unlimited unpaid work.

Use the unit-economics guide for allocated costs and the profitability guide for company payroll and cash. Before treating the quote as ready, retain the sample scope, timed task sheet, signed exclusions, owner review plan and price calculation. Those records make the retainer reviewable when actual work differs from the estimate.
