Collection email templates

Six templates covering the full cadence — from pre-due confirmation to final notice. Copy, replace the {{placeholders}}, and send. The pre-due confirmation is the one most teams skip and the one that prevents the most late payments.

Published August 19, 2026 · Updated August 19, 2026

1. Pre-due confirmation (5–7 days before due date)

The single highest-leverage email in collections: it surfaces blockers (wrong PO, missing document, wrong recipient) while there is still time to fix them before the due date.

Subject: Invoice {{invoice_number}} — due {{due_date}}, all set on your side?

Hi {{first_name}},

Quick check ahead of the due date: invoice {{invoice_number}} for {{amount}} is due on {{due_date}}.

Could you confirm it's been received and is approved for payment? If anything is holding it up — a PO reference, a document you need from us, or a different contact it should go to — reply here and I'll sort it out today.

Thanks,
{{your_name}}

2. Due-date reminder

Neutral and assumptive — most late payment at this stage is oversight, and the tone should say so.

Subject: Invoice {{invoice_number}} due today

Hi {{first_name}},

A quick reminder that invoice {{invoice_number}} for {{amount}} is due today, {{due_date}}.

You can pay via {{payment_link_or_method}}. If it's already scheduled, no action needed — and if anything is blocking it, just reply and let me know.

Best,
{{your_name}}

3. First follow-up (7 days past due)

Asks a diagnostic question instead of escalating pressure — you want the blocker, not a standoff.

Subject: Invoice {{invoice_number}} — 7 days past due

Hi {{first_name}},

Invoice {{invoice_number}} for {{amount}} was due on {{due_date}} and I haven't seen payment come through yet.

Is anything holding it up on your side? Common culprits are a PO mismatch, a missing document, or the invoice reaching the wrong inbox — all quick for me to fix if you point me at the problem.

If it's simply in the queue, could you share the expected payment date?

Thanks,
{{your_name}}

4. Broken-promise follow-up

Refers back to the specific commitment. Polite, factual, and impossible to misread.

Subject: Following up — payment for {{invoice_number}} expected {{promised_date}}

Hi {{first_name}},

When we spoke on {{conversation_date}}, payment for invoice {{invoice_number}} ({{amount}}) was expected by {{promised_date}}. It hasn't arrived yet.

Could you let me know where it stands? If the date needs to move, I'd rather have the real one — it helps us plan and keeps this off both our lists.

Thanks,
{{your_name}}

5. Escalation (30 days past due)

Introduces a named next step without threatening. Copying a second contact changes behavior more than stronger adjectives do.

Subject: Invoice {{invoice_number}} — 30 days past due, action needed

Hi {{first_name}},

Invoice {{invoice_number}} for {{amount}} is now 30 days past due. I've copied {{their_manager_or_ap_lead}} so we can get this resolved together.

If there's a dispute or a problem with the invoice, tell me and I'll fix it this week. Otherwise, please confirm a payment date by {{response_deadline}}.

Per our terms, balances beyond {{terms_threshold}} may accrue late fees of {{late_fee_terms}} — I'd much rather resolve this before that applies.

Regards,
{{your_name}}

6. Final notice before collections

Clear, specific, and final — with a date and a way out. Send it only if you mean it.

Subject: Final notice — invoice {{invoice_number}}

Dear {{first_name}},

Despite several reminders, invoice {{invoice_number}} for {{amount}}, due {{due_date}}, remains unpaid.

Unless payment is received or a payment plan is agreed by {{final_deadline}}, we will refer this balance to a collections process and pause further work/orders on the account.

To resolve it today: pay via {{payment_link_or_method}}, or reply to arrange a plan. If you believe this invoice is in error, tell me now and I will put the process on hold while we review.

Regards,
{{your_name}}
