When a staffing timesheet is corrected after the customer invoice was issued, preserve the original invoice and forecast snapshot, quantify the approved change, and document the billing treatment before changing expected cash. Do not silently edit historical hours or count both the original and corrected amount.

Establish the source sequence

Record the worker, customer, service period, original approved hours, corrected hours, edit date, approval status, invoice ID, and amount affected. The timesheet change and the invoice change are separate events even when they are related.

QuickBooks Time supports approval, unapproval, rejection, editing, and timesheet history. That history can establish what changed in the source time record. It does not determine the customer billing outcome by itself. Finance still needs an approved decision to leave the invoice unchanged, issue a credit, add a charge, or replace a document.

The staffing timesheet invoice-readiness guide covers the pre-invoice boundary. This page begins after the invoice already exists.

Build the billing bridge

Use one reconciliation table with these amounts:

  • Original approved billable hours and rate basis
  • Original invoice amount attributable to those hours
  • Corrected approved hours
  • Supported billing adjustment
  • Credit, supplemental invoice, or no-change decision
  • Current open balance and expected new cash

The bridge should explain the difference without prescribing accounting treatment. Accounting, contract, and customer-approval decisions remain with the business and its advisers.

If the original invoice is credited and replaced, follow the corrected and reissued invoice workflow so only one supported residual remains in the cash forecast.

Reassess collection timing

A timesheet correction may create a customer review dependency even when the invoice balance has not changed yet. Track whether the customer must approve the correction, whether a revised document was delivered, and whether any existing payment commitment still applies.

Do not automatically restart the due-date clock or assume the correction creates a fixed delay. Keep the recorded due date separate from the expected collection date. If customer acceptance is pending, assign an owner and review date and reduce forecast confidence rather than selecting an invented payment day.

The AR exceptions report template can hold the discrepancy, evidence, owner, and next action.

Minimum handoff fields

Staffing operations should provide timesheet ID, worker, customer, service dates, original and corrected hours, edit history, approval status, rate reference, invoice ID, and supporting note. Finance should add billing decision, document IDs, open balance, expected-cash effect, customer-review status, owner, and review date.

Decision rule

Treat a post-invoice timesheet correction as a versioned source exception. Reconcile hours to billing, billing to open AR, and open AR to one supported cash assumption. Staffing finance teams can apply for AR Pulse for an invoice-level action list and four-week collections view.
