The Friendly Check-In
Copy-paste friendly invoice reminder template for the day after the due date. Keeps the relationship warm while getting your invoice back on their radar.
The template
Subject: Quick note on invoice #{invoice_number}
Hi {client_name}, Hope the week's treating you well! Quick note that invoice #{invoice_number} for {amount} came due on {due_date}. No rush if it's already on its way — just wanted to make sure it didn't get buried. Let me know if you need anything from my end (a PO number, a different format, whatever helps). Thanks! {your_name}
Replace the {curly} bits with your details. That's it.
When to use it
- Your first follow-up, right after the due date
- Clients you have a good relationship with
- Any invoice size — this one never offends
Pro tips
- →Send within 24 hours of the due date — waiting a week signals the deadline didn't matter
- →Assume good intent. Most late invoices are chaos, not malice
- →Always put the invoice number in the subject line so it's searchable
- →Keep it short. Three sentences out-perform three paragraphs
