Short answer
A good bookkeeping client reminder email names the exact missing item, states why it matters for close, gives one clear deadline, and points the client to the correct place to send or upload it. The reminder should not restart the whole request; it should narrow the blocker.
Three-message reminder cadence
Initial request
Subject: Monthly close documents needed
Hi - to start this month's close, please send or upload the items below by [date]. Items needed: [specific list].
First reminder
Subject: Still missing for monthly close
Hi - we have most of what we need. The close is still waiting on: [specific list]. Please send by [date] so we can keep the month moving.
Escalation note
Subject: Close is blocked by missing documents
Hi - we still need [specific list]. If these are unavailable, please reply with how you want us to handle the blocked items this month.
Make reminders easier to act on
- Use bullets, not paragraphs, for missing items.
- Include only current blockers.
- Tell the client where to send/upload documents.
- Use a consistent deadline format.
- Track whether the reminder was sent, seen, answered, or escalated.
What to avoid
- Vague "just checking in" reminders.
- Resending the entire monthly request every time.
- Mixing accounting questions with document requests in one email.
- Leaving the staff owner unclear.
FAQ
How many reminder emails should a bookkeeper send?
Use a defined cadence, not unlimited chasing. Three steps is usually enough for a workflow: initial request, specific reminder, and escalation/blocked-close note.
Should reminders come from one person?
Usually yes. One visible owner reduces duplicated asks and conflicting messages.
