What to send when an invoice is 1 day overdue: a friendly reminder template, timing advice and the next step if it stays unpaid.
The invoice is one day late. This is almost always an admin slip, so the tone should be light and helpful.
Below is a copy-ready template. Swap the [brackets] for your details, or let PaidNudge write a tailored version and the rest of the follow-up sequence.
Subject: Invoice [INV-123] (1 day overdue) for [amount] Hi [Name], Just a quick heads-up that invoice [INV-123] for [amount] was due yesterday ([due date]). In case it slipped through, I've attached it again. You can pay by [payment link / bank details]. If it's already on its way, please ignore this. Thanks! Thanks, [Your name]

Email first so there's a written record, then a short call if there's no reply. Confirm anything agreed on the phone by email.
Move one step up the ladder: friendly → firm with deadline → final notice / letter before action → small claim or collection.
