Hi {{client_first_name}},

I wanted to follow up on invoice {{invoice_number}} for {{amount}}, which was due {{due_date}}. I know things slip through — could you confirm whether it's been processed on your end?

Happy to resend it or split it differently if that helps.

Subject: Re: Invoice {{invoice_number}} — still outstanding

Hi {{client_first_name}},

Circling back on invoice {{invoice_number}} for {{amount}}. It's now a week past due. Could you give me a quick update on when I can expect payment, or let me know if there's a hold-up I can help unblock?

Pay link if useful: {{invoice_link}}

Subject: Invoice {{invoice_number}} — please review

Hi {{client_first_name}},

Invoice {{invoice_number}} for {{amount}} is now two weeks overdue and I haven't heard back on my last two notes. I'd like to keep this simple — could you let me know today when payment will be sent?

If there's a dispute I'm not aware of, please reply so we can resolve it. Otherwise I'll need to pause any new work until this is settled.

Thanks,
