See the recorded product workflowDecisions to make before billing
Retainer closeout has two separate jobs: finish the current billing period correctly and prevent a future invoice from being sent for service that has ended. A final invoice alone does not prove the recurring schedule has been reviewed.
Begin with the agreed final service date and notice terms. A partial period may use calendar-day proration, a minimum fee, reserved capacity, or another agreed basis. Do not choose a lower or higher charge merely because a calculator can produce it. Record the method and approval before drafting.
The closeout record should cover future schedules, unsent drafts, received advances, approved extras, open invoices, and the person handling later payment questions. InvoiceAgent's scheduling controls support delivery planning; your team must still check the agreement, reconcile payments, and verify the next send will not be duplicated.

Outcome
Use this page to move from general research into a calmer, more repeatable invoicing process.
Work through the billing decision
Confirm the final service and billing basis
Write the final service dates, notice reference, full-period fee, and any agreed partial-period method. List approved extras and excluded pending requests separately. Confirm the final charge with the appropriate client contact.
Review every future send
Check the recurring rule, next planned invoice, and any separately scheduled draft. Stop or adjust future delivery under your workflow and verify the resulting state. Changing a note on the client record is not enough.
Reconcile and hand over the remaining work
Check confirmed receipts, unapplied advances, credits, and unpaid invoices. Record the final document references, handover owner, and next review date for unresolved items. Keep an open invoice visible after the service relationship ends.

Avoid this
Assuming closeout means everything is paid
A completed service and a settled invoice are different states. Record the actual outstanding balance and who will respond to payment questions.
Avoid this
Using proration as a cancellation rule
A day-based subtotal is arithmetic, not a right to cancel or receive a refund. Use the method and notice terms agreed for the retainer.

Questions people usually have before changing the workflow.
Should I delete the recurring history?
Preserve the relevant invoice and delivery records. Review future sends without removing the evidence needed to reconcile previous periods.
What if the final day is mid-month?
Use the billing basis agreed for that situation. If calendar-day proration is agreed, record the full period and inclusive active dates explicitly.
Can reminders continue after service ends?
Review them against the actual unpaid balance and any dispute or payment promise. Ending service does not by itself resolve the invoice, and a settled invoice should not keep receiving stale reminders.
