1-Day Overdue Invoice Reminder Email Templates
One day overdue is usually a simple miss, not a conflict. Use these templates to prompt payment today or get a specific date without sounding pushy.
Generate free previewWhen to use / when to send
- Send this on the first business day after {{DueDate}} when invoice #{{InvoiceNumber}} hasn’t been paid yet.
- Use a calm, assume-positive tone: treat it like a simple miss, not a dispute.
- Your goal is binary: get paid today via {{PayLink}} or get an exact date they can commit to.
- If they reply without a date ("soon", "processing"), immediately ask for the scheduled payment date.
- If there’s no response after one bump, switch channels: call or voicemail using {{Phone}} and remind them to reply by {{ReplyByDate}}.
- If they indicate a real issue (approval, vendor setup, PO), move to problem-solving instead of sending more reminders.
Checklist / what to include
- Invoice #{{InvoiceNumber}} and total {{Amount}}
- Original due date {{DueDate}} and status (now overdue)
- One clear action: pay via {{PayLink}}
- Second option: reply with the exact payment date
- A reply deadline: please respond by {{ReplyByDate}}
Copy/paste templates
Recommended timing / follow-up plan
- Day 1 overdue: send the friendly reminder with {{PayLink}}
- Day 2 overdue: if no reply, send a shorter bump asking for an exact pay date
- Day 4 overdue: call or voicemail and reference invoice #{{InvoiceNumber}}
- Day 7 overdue: switch to a firmer email with a reply deadline ({{ReplyByDate}})
- Day 14 overdue: move to escalation messaging with {{DeadlineDate}}
Best practices / common mistakes
- Do: write as if it’s an oversight, not bad intent
- Do: keep one CTA ({{PayLink}}) and one ask (pay or exact date)
- Don’t: send long context—stick to invoice facts and next action
- Don’t: threaten consequences on day 1 overdue
- Do: ask for the scheduled payment date if they claim it’s “processing”
