What Net 30 means—and when the clock starts
Net 30 means payment is due 30 days after the invoice date unless you and the client agree otherwise (for example, 30 days after receipt or acceptance). Write the rule once on the PDF: “Payment terms: Net 30 from invoice date. Due date: [calendar date].” Accounts payable teams schedule from that due date; “Net 30” alone in an email without a date is easy to misread. If your agreement starts the clock on receipt, say so explicitly so day-30 is not a surprise.
Terms-tied cadence: day 0, 27, 30, and 37
Day 0: send the invoice with Net 30, the calendar due date, PDF, and Stripe pay-now link in one message. Day 27: a light AP-friendly nudge that names the due date and terms (“Net 30 — due [date]”) so approval can finish on time. Day 30: a same-day due notice that restates amount, invoice number, and pay-now—still terms language, not a collections tone. Day 37: a short status ask (“Has this cleared, or is there a blocker?”) before you escalate tone. That ladder is about the Net 30 clock; firmer overdue wording lives on the overdue email guide.
Subject lines that name terms and due date
Prefer subjects that carry the clock: “Invoice INV-1042 — Net 30, due June 30” or “Reminder: INV-1042 due in 3 days (Net 30).” Avoid vague subjects like “Quick reminder” that hide the terms. Keep the PDF and pay-now link in the body so the client does not hunt for how to pay. When you need sample chase paragraphs after the balance is late, switch to the overdue invoice email examples instead of stretching this page into another template dump.
