Plumbing Month-End Checklist: Give the Bookkeeper Clean Records

Separate operational preparation from accounting close

The office can verify whether jobs were completed, invoices were prepared, and payment references are present. The accountant determines the appropriate accounting treatment, period recognition, tax handling, and final reconciliation.

Do not equate job completion, invoice date, and cash receipt automatically. They may occur in different periods and serve different reporting purposes.

This checklist is a preparation framework, not a replacement for professional accounting procedures.

Use a month-end handoff checklist

MONTH-END OPERATIONS HANDOFF
Reporting period and cutoff: [dates/time basis]
[ ] Completed jobs reviewed for missing invoices
[ ] Invoice drafts and unsent bills reviewed
[ ] Approved changes reflected in billing records
[ ] Deposits and partial payments allocated or flagged
[ ] Reported payments verified or listed as unresolved
[ ] Processor/bank settlement references available
[ ] Refunds, credits and reversals documented
[ ] Customer overpayments reviewed
[ ] Required supplier/job-cost records collected
[ ] Duplicate customer or invoice candidates flagged
[ ] Open disputes and billing exceptions assigned
[ ] Bookkeeper receives references and specific questions
[ ] Final adjustments returned to the operational owner

Use an explicit cutoff. If some records are still arriving or a relevant account is not reconciled, label the handoff as provisional rather than presenting a complete final month.

Review completed work that has not reached billing

Create a list of completed jobs with no relevant invoice or documented billing exception. Check whether the reason is an agreed milestone, missing approval evidence, an administrative delay, or a data-linking problem.

Do not invoice automatically just because a report contains the word complete. Review the actual billing basis and scope. The completed-not-invoiced guide provides a dedicated exception process.

Reconcile customer-payment questions

Identify unallocated payments, partial payments, duplicate candidates, and customer claims of payment that still need verification. Give the bookkeeper the relevant invoice and transaction references.

A processor payout should be explainable through its underlying records. Do not classify an unexplained difference as a fee merely to make a worksheet balance.

Avoid changing reconciled records casually

Intuit advises involving an accountant before changing already reconciled transactions. Apply the same caution when a operational correction may affect a closed period or formal report. Official source

Preserve the original reference and document the correction. Do not delete an inconvenient record merely because the latest spreadsheet looks cleaner without it.

Close the feedback loop

After the accountant resolves the questions, update the operational exception log and relevant customer records through the approved process. Otherwise, the office may keep sending reminders or reopening issues that accounting already resolved.

Review recurring gaps such as missing job references or delayed completion notes. A better month-end process begins with consistent daily records, not a larger last-day cleanup effort.
