Send the first reminder 3 to 7 days before the due date, the second on the due date, and the third 7 days after. Most invoices get paid after touch one or two. The contractors who get paid fastest aren't the most aggressive — they're the most predictable.
Done in seconds. No sign-up required.
Five touches cover almost every payment scenario.
| Timing | Touch | Tone | What to mention |
|---|---|---|---|
| 3–7 days before due | Pre-due reminder | Friendly, optional | Invoice number, due date, "just a heads-up" |
| On the due date | Day-of reminder | Neutral, factual | Invoice number, amount, payment method |
| 7 days late | First overdue notice | Polite, slightly firmer | How many days past due, ask for an update |
| 14 days late | Second overdue notice | Firm, business-like | Reference contract terms, late fees if applicable |
| 30 days late | Final demand | Formal | Deadline for payment, mention of next steps |
Most billing guides skip the pre-due reminder and start with the day-of notice. That's a mistake. The pre-due email isn't about chasing — it's about making sure the invoice actually reaches the right inbox before the deadline. About 30% of small business invoices get paid late, and a large share of those would have been paid on time if the client had seen the invoice a few days earlier.
The pre-due email also gives the client a chance to flag a problem. Wrong PO number, missing approval, an accounts-payable system that needs the invoice in a specific format. Better to catch that 5 days before the deadline than 5 days after.
Short, friendly, almost casual. Subject line: Quick heads-up on invoice #1042. Body: one sentence noting the upcoming due date and offering to clarify anything. The goal is awareness, not pressure.
Drop the courtesy framing. State that the invoice is due today, attach it again, list the amount. Subject line: Invoice #1042 — due today. No apologies, no "just checking in" — clients can tell when you\'re hedging.
Acknowledge the gap. "Following up on invoice #1042, now 7 days past due." Ask for a payment update or a date. Stay polite; most late payments are oversight, not bad faith.
Reference your contract terms. If you charge late fees, name the amount and the date it kicks in. Request a response by a specific date — not "as soon as possible."
Formal tone. State the total owed, the deadline for payment, and what happens next if it\'s missed (collections, legal action, suspension of work). Send certified if the relationship is already broken.
Wording for each of these touches lives on the polite payment reminder wording page. If the invoice is already 30+ days overdue and you\'re not sure how to escalate, the overdue invoice follow-up guide covers it.
3 to 7 days before the due date. It's framed as a courtesy, not a chase. Most clients appreciate the heads-up because invoices get buried in inboxes, and a soft pre-due nudge often gets paid that same week.
Send the second one on the due date itself. Neutral tone, just stating the invoice is now due. If the client paid that morning, they'll reply with the confirmation. If they forgot, you've caught it on day one rather than week three.
Once a week is the common cadence: 7 days late, 14 days late, 30 days late. Each touch escalates in tone — friendly nudge, neutral reminder, then a firmer note referencing late fees or next steps. Avoid daily emails; they read as panic, not professionalism.
No. Send during business hours, Monday through Thursday morning ideally. Friday afternoons and weekends get lost in the inbox shuffle, and a payment reminder on a Sunday reads as unprofessional. Tuesday and Wednesday mornings have the highest open rates for business email.
Around the 14-day-late mark for most contractors. Before then, the tone stays neutral and assumes oversight. At 14 days, you can reference late fees if your contract includes them. At 30 days, it becomes a formal demand letter referencing collections or legal action.
BoldRemind reminds you, the contractor, on each touch date. You write and send the actual email to your client. That keeps every message in your voice, on your domain, and avoids the spam-flag and tone-deaf risks of full client-side automation. Set one reminder per touch — three or four reminders covers the standard cadence.
Set one reminder per touch. BoldRemind nudges you when each one is due, so the rhythm runs itself and your follow-ups never slip a week.
