What to send when a freelance invoice is late

The due date is a calendar fact, not a fight

The work already shipped. The hours already left that week. What changed is the date on the invoice: it is now in the past. The first note after that date is a reminder with three facts — the original amount, the due date that passed, and how they pay — not a speech about respect.

If they have not started and the PO still says Net 30, nothing is overdue yet. Do not send this chase. Compare cash this week vs 100% in N days on Net 30 vs deposit.

If the invoice is still net — not past due — and you want cash this week by selling that bill, that is keep = invoice × (1 − share you type) on the invoice-factor card, not this follow-up. Chase hours live here. Haircutting a current receivable lives there.

If the invoice already sat and you want the extra named as a share of the face value, that is extra = invoice × share you type on the late-fee card. Worked there: $5,000 × 0.015 = $75. Still owed = invoice + extra. You type the 0.015. Not 1.5%/month. Not Prompt Payment Act. Not this chase email. Two products: the sentence lives here; the sitting extra lives there.

Day-one copy that sounds like a courtroom does not collect faster. It just makes a late transfer feel like a conflict. Paste the sentence from the card. Add the invoice number and the same payment link you already sent. That is the whole job of the first follow-up.

A cadence you choose after the date

Pick a follow-up calendar you can actually keep. This is not a statute and not a collections timeline:

• 1–2 days past due. Short check-in. Original amount. Due date. Payment path. Assume it slipped, not that they vanished.
• ~7 days late. Same facts. Ask for a payment date this week, or a one-line reply if something is blocked on their side.
• ~14 days late. Pause new work for this client until the open invoice clears. Say that in one clause. Do not start the next sprint on a handshake.

The presets on the card (7 days, 14 days, Net 15 then 7 overdue) only fill the day count and the due-date text. They do not invent a penalty.

A late-fee percent you already wrote down — or none

This card will not invent a legal rate or a daily interest print. You type a percent, or you leave it blank.

Formula, one shot on the unpaid invoice: late-fee dollars = invoice × (percent you type ÷ 100). Amount still owed = original + that fee. Empty or 0 → fee is $0, and the follow-up line still writes. There is no compounding, no APR, and no 50-state table hiding behind the box.

Only type a percent that already lives in the signed quote or SOW. Putting a number here does not create a term. If the quote is silent, leave the box empty and follow up for the original amount. Actual terms live in that signed document, not on this page.

Worked example: $2,400, Net 15, 7 days overdue

Invoice $2,400. Due text Net 15. Days late 7. Leave late-fee % empty → fee $0, amount still owed $2,400, and the card still writes a follow-up sentence.

If — and only if — the signed quote already named a percent, you might type an example such as 5% (change it; it is not a recommended legal rate): fee = 2,400 × 0.05 = $120. Planning total = $2,520. Confirm that 5% in the SOW before the email mentions it.

Optional hours: 24 already billed means 24 hours already left the calendar the hourly floor was built on. Hours do not change the invoice math on this card. They are a reminder that the week is gone even if the payment is not.

Write facts. Skip heat.

The card’s sentence is built to be pasted. You add the invoice number and the link. Shape of a useful note:

• Lead with the invoice amount and the due date that passed, then how many days late.
• Name the amount still owed. If a percent is in the signed terms, one clause — not a paragraph — and only after you confirmed it.
• Ask for payment this week or a date if something is blocked. Offer to resend the link.
• Skip shame, fake urgency, “final notice” on day one, and any line that sounds like collections. Those are not this page’s job.

Example with a blank percent: Checking in on the invoice for $2,400, due Net 15 and now 7 days past that date. The amount still owed is $2,400. Please send payment this week or reply with a date if something is blocked. Paste from the card so the math matches the note.

Pause the next sprint before you write a novel

Unpaid work already spent the hours. New work should wait. The next job takes a deposit so kickoff and cash show up in the same week. Rebuild the next number on the project quote guide; if this client is always late, the next rate conversation belongs on raise a freelance rate, not in a longer overdue email.

This page is not how to sue, garnish, sell the debt, or run a collections agency. If you need an enforceable clause, a lawyer in your jurisdiction writes it into the next SOW — before the work starts.

This page is planning, not collections

Educational only — not legal, tax, or collections advice. We do not invent a required late-fee percent, a statutory interest rate, or a 50-state tax engine. Confirm live terms in the signed quote or SOW you already use. The math here is: invoice amount, days late, an optional percent you type, optional hours already billed, amount still owed, one email-sized sentence.
