Why invoice reminders fail in WooCommerce
Many stores send a normal order email and call it an invoice reminder. That breaks down when the customer asks for the original PDF, the accountant asks for payment terms, or support needs proof that a resend happened.
Use this guide when evaluating a WooCommerce invoice plugin, replacing a PDF invoice tool, or preparing BACS/proforma reminder workflows for EU VAT customers.
Reminder-template readiness checklist
1. Include the invoice number and retained PDF link
The reminder should point to the issued invoice number and a stable customer-download URL. Do not rely on a generic order link when the finance team needs the actual VAT invoice PDF.
Buyer question: Can every reminder include the correct invoice PDF link and show that the PDF was already issued?
2. Make payment terms visible before the overdue notice
For BACS, proforma, Net 14, and Net 30 flows, the first reminder should show payment terms and due date. Later reminders should clearly say why the invoice is overdue.
Buyer question: Does the plugin store due date and payment terms per invoice so email text is not guessed from the order date?
3. Keep a send, fail, and resend log
A reminder template only helps if support can see whether it was sent, bounced, manually resent, or followed by a customer download. Log each event on the invoice workflow timeline.
Buyer question: Can support prove that a reminder was sent and resend it without changing the issued invoice?
4. Separate proforma requests from final invoice reminders
A proforma payment request before payment is not the same as a reminder for an already issued final VAT invoice. The template wording and PDF links should reflect that distinction.
Buyer question: Can the workflow choose different templates for proforma, final invoice, overdue invoice, and credit-note follow-up?
5. Give accounting a clean handoff
Exported reminder evidence should include invoice number, customer, due date, payment method, send timestamps, resend notes, payment date, and any credit-note or correction link.
Buyer question: Will the accountant receive reminder history alongside invoice PDFs and payment reconciliation data?
Three reminder templates to map before buying
Friendly pre-due reminder
When to send: 3–5 days before a Net 14/30 due date or after a proforma has been accepted.
Must include: Invoice number, PDF download link, due date, bank details, VAT number reference, and support contact.
First overdue reminder
When to send: 1–3 days after the due date when the invoice is unpaid and no failed-send issue is known.
Must include: Original invoice link, due date, outstanding amount, payment method, and a clear but neutral overdue line.
Finance handoff / final notice
When to send: After internal review, not automatically for every store. Especially useful for B2B accounts-payable workflows.
Must include: Reminder history, payment terms, invoice PDF, purchase order reference, customer download evidence, and next action.

Send my reminder workflowFAQ
Can WooCommerce send automatic invoice reminder emails?
WooCommerce can send order emails, but invoice reminder workflows usually need extra due-date metadata, PDF invoice links, BACS payment details, failed-send logs, customer download fallbacks, and accounting evidence.
What should a WooCommerce invoice reminder email template include?
Include invoice number, retained PDF download link, due date, payment terms, outstanding amount, bank details or payment link, customer VAT/reference details, support contact, and a short explanation of why the message was sent.
Should reminder emails change the issued VAT invoice?
No. The reminder should reference the retained invoice and payment timeline. If a fee, correction, or credit note is needed later, create explicit follow-up evidence instead of modifying the original PDF silently.
Where does Lattice Invoices fit?
Lattice Invoices is the early-access WooCommerce EU invoicing path for stores that need invoice PDFs, BACS/proforma workflows, due dates, reminders, resend logs, customer downloads, credit notes, corrections, and accountant-ready exports.
