Hi {{ClientName}},

Regarding invoice #{{InvoiceNumber}} ({{Amount}}), originally due {{DueDate}}.

Per our conversation/request, we can offer a new deadline of {{DueDate}}. Payment can be made at {{PayLink}}.

Let me know if you have questions, or please reply to confirm you’ll meet the new date.

Thank you,
{{YourName}}
{{Company}}

Follow-up plan + common mistakes

Get client confirmation in writing—verbal agreements are not enough.
If payment doesn’t arrive by the new date, reference this agreement in any escalation.
Do not repeatedly extend without cause—one clear extension per invoice.
Keep the new date realistic and enforceable.
Avoid emotional justifications; stick to policy where possible.

FAQ

Generally, no. One clear extension with a new written date sets a boundary and keeps timelines enforceable.
