Template
Sent as the final payment escalation for B2B SaaS customers (larger accounts, AP departments, purchase orders). Goal: formalize the escalation without damaging the relationship, and give the AP team everything they need to pay.
A/B test these. Lowercase, question format, and specific-time framings consistently win.
Final payment notice: {{product_name}} invoice {{invoice_number}}Action required: payment overdue on {{invoice_number}}Your {{product_name}} account will be suspended {{suspension_date}}Hi {{first_name}},
Final notice on invoice {{invoice_number}} for
{{product_name}} ({{plan_name}}), ${{amount}}, originally due
{{original_due_date}}.
We have attempted to charge the card on file 4 times over the
past 14 days without success. If the invoice remains unpaid by
{{suspension_date}}, the account will be suspended and the
following services will pause:
- {{service_1}}
- {{service_2}}
- {{service_3}}
To resolve, please choose one:
1. Update the payment method on file: {{secure_update_link}}
2. Pay by ACH or wire - reply to this email and we will send
instructions.
3. Forward to your AP team - this email includes the original
invoice PDF and PO reference ({{po_number}}).
If you need to renegotiate terms or have a question about the
invoice, please contact {{account_manager_name}} directly at
{{account_manager_email}}.
- {{sender_first_name}}
{{sender_title}}, {{product_name}}Variables in {{like_this}} should be replaced with your merge fields.
Formal tone appropriate for AP departments who will never see the friendly founder emails. Includes invoice and PO numbers so AP can look it up. ACH/wire option and AP forwarding path acknowledge that B2B payment rarely happens via a card click. Account manager escalation preserves the sales relationship separately from billing.
For accounts under ~$500/mo, yes. For larger accounts with a dedicated account manager, send from the account manager or Customer Success lead. AP departments expect a business contact, not a founder signature, for larger invoices.
Yes for B2B. AP departments file by PDF; links get lost in Slack forwards and multi-person review. Always include the invoice PDF as an attachment for B2B dunning.
Automate this with Rebounce
Rebounce detects payment failures via Stripe Connect, classifies them by decline code, and runs the optimal dunning sequence across email, SMS, WhatsApp, and in-app banners. The templates above are the exact patterns Rebounce uses out of the box - you can adapt the copy to your brand voice and Rebounce handles delivery, timing, and sequence cancellation when a retry succeeds.
Start free trialSent on day 14 after all retries and prior emails have failed. The grace period is over. Goal: close cleanly, preserve goodwill, and leave the door open for reactivation. A well-done final notice is often the best win-back hook you have.
Sent on day 7 after two prior emails did not work. The customer has ignored both. This email is not about payment mechanics anymore - it is about what they are about to lose. Goal: make the loss concrete and offer a clean exit if they want out.
Sent on day 3 after the friendly heads-up did not recover the payment. The customer has ignored the first email. Goal: be direct without being aggressive, and preempt silent churn.
