Why invoice reminder copy is a purchase-intent problem
Stores searching for a WooCommerce invoice reminder email template usually have an active B2B cash-flow problem: unpaid bank-transfer orders, finance teams asking for VAT details, or customers that need a proforma before payment. That makes this a strong wedge for Lattice Invoices.
The template is only half the solution. The workflow also needs invoice-ready checkout fields, clean order status rules, PDF/proforma links, reminder logging, final invoice delivery, and credit-note handling after refunds.
2–3 days after a pending BACS or manual invoice order
First unpaid invoice reminder
Subject
Reminder: payment needed for WooCommerce order #{order_number}
Template copy
Hi {billing_first_name}, this is a friendly reminder that order #{order_number} for {order_total} is still waiting for payment. Please use the payment details below and include reference {order_number}. If your finance team needs a proforma, VAT number, PO reference, or invoice email updated before payment, reply to this message.
6–7 days after the order, before stock/license/service access is released
Final pre-cancellation reminder
Subject
Final reminder before order #{order_number} is cancelled
Template copy
Hi {billing_first_name}, order #{order_number} is still unpaid. We will cancel the order on {due_date} unless payment arrives or your team confirms that finance approval is in progress. The final VAT invoice PDF will be issued after payment so the invoice number, VAT totals, and customer download remain correct.
Immediately after the bank transfer is matched and the order becomes processing/completed
Paid invoice delivery note
Subject
Paid invoice for WooCommerce order #{order_number}
Template copy
Hi {billing_first_name}, thank you — payment for order #{order_number} has been received. The final invoice PDF is attached and also available from My Account. If you need a credit note later for a refund, please reference invoice {invoice_number}.
Fields the email must pull from WooCommerce
Workflow rules before using the template
Do not call every reminder a final invoice
For many EU B2B stores the safer pattern is payment request or proforma before payment, then final VAT invoice once the order is paid. That avoids gaps in invoice numbering and confused customers.
Keep the reminder tied to WooCommerce order status
The template should know whether the order is pending, on-hold, processing, completed, refunded, or cancelled. Generic marketing emails create support work because they cannot explain invoice state.
Collect finance-team fields before the reminder fires
If the checkout does not capture VAT/BTW number, company name, invoice email, and PO reference, every reminder becomes a request for corrected paperwork.
Log what was sent for accountant handoff
A B2B store should be able to prove when reminders were sent, which PDF/proforma was linked, and when the paid final invoice was issued.
Turn reminder copy into a €49 early-access request
If the store already sends invoice reminders manually, the next paid step is not another generic email plugin. It is a WooCommerce invoice workflow that knows when to send proforma requests, when to issue final VAT PDFs, and how to keep reminder history useful for bookkeeping.

Can I copy these WooCommerce invoice reminder email templates?
Yes. Treat them as starting copy for BACS, bank-transfer, or manual invoice payment workflows. Replace placeholders like order number, due date, amount, invoice number, and payment reference with live WooCommerce data.
Should the reminder attach a PDF invoice before payment?
Only if the store intentionally uses proforma/payment-request PDFs before payment. The final VAT invoice is often cleaner after payment, because invoice numbering, paid date, VAT evidence, and customer downloads stay aligned.
What does this have to do with Lattice Invoices?
This is a buyer-intent workflow Lattice Invoices can own: invoice-ready checkout fields, proforma/payment reminders, final paid invoice PDFs, customer downloads, and refund credit-note links.
How do I request early access for this reminder workflow?
Send store URL, country, payment method, required VAT fields, due-date rules, reminder schedule, and whether you need proforma PDFs before payment. The CTA on this page pre-fills that request.
