Chase an overdue invoice and actually get paid — a firm-but-friendly escalation ladder that protects the client relationship until it's clear the relationship is the problem. Use when asked to chase an unpaid invoice, my client hasn't paid, write a payment reminder, or how do I get a late-paying client to pay. Produces a staged sequence of messages (gentle nudge → firm reminder → final notice → next steps) timed to the overdue days, with late-fee and work-pause options and a note on what to keep for the record.
Start a fresh conversation. Replace the highlighted placeholders.
Use late-invoice-chaser to draft a timed four-message payment-chase sequence for [invoice details], reflecting [relationship and goal] and [terms and prior contact].

Late-Invoice Chaser
Freelancers and small businesses lose more to unpaid invoices than to bad pricing — and the reason is usually awkwardness, not the client's cash flow. A calm, escalating sequence removes the awkwardness: each message is warmer than you feel and firmer than the last, so you get paid without torching a good client — and you have a clean paper trail if it comes to that.

What This Skill Produces
The staged sequence — 4 messages tuned to how overdue it is: friendly nudge → firm reminder → final notice → next-steps letter
The timing plan — when to send each, based on your terms and days overdue
The levers — when to mention late fees / interest (if your terms allow), pausing work, or withholding deliverables — and how to phrase them without a threat
The record note — what to keep (invoice, terms, delivery proof, every message) in case it goes to a formal demand or small claims
Required Inputs
Ask for these if not provided:
The invoice — amount, invoice date, due date / payment terms, and how overdue it is now
The relationship — long-standing good client, new client, or already rocky
Your terms — do they allow late fees/interest? Is more work in flight you could pause?
What's happened so far — any replies, promises, or silence
Your goal — keep the client and get paid, or get paid and move on
Framework: Warm, Then Firm, Then Formal
Assume the best first. The opening nudge treats it as an oversight — most late payments are. A friendly "just floating this to the top of your inbox" often works alone.
Escalate tone on a schedule, not on emotion. Each step gets firmer and more specific (invoice #, amount, days overdue, a clear pay-by date) — driven by the calendar, not by how annoyed you are.
Make paying the easy path. Re-attach the invoice, restate the amount and methods, and give a specific new due date in every message. Remove every reason to delay.
Introduce consequences factually. Late fees (only if your terms allow), pausing active work, or holding final files — stated as policy, not punishment: "per our terms, invoices 30 days overdue accrue…".
Keep the record clean. Save the invoice, the agreed terms, proof the work was delivered, and every message. If it reaches a formal demand or small claims, this is your case.

Next steps
Formal, factual
1 · Gentle nudge
[Warm one-liner, invoice re-attached, amount + new pay-by]
2 · Firm reminder
[Invoice #, amount, days overdue, specific date, payment methods]
3 · Final notice
[Clear pay-by, the lever: late fee / paused work / held deliverables — as policy]
4 · Next steps
[Factual: what happens next — formal demand / small claims / collections — with a final chance to resolve]
Keep for the record: invoice · signed terms/agreement · delivery proof · every message + reply.
Quality Checks
The first message assumes good faith and is genuinely friendly
Each step is firmer and includes invoice #, amount, and a specific new pay-by date
Late fees are only invoked if the stated terms allow them
Consequences are phrased as policy, not threats
Timing is tied to days overdue, not emotion
A record-keeping note is included for the formal path
Anti-Patterns
Opening angry — a hostile first nudge burns a client who simply forgot.
Vague reminders with no invoice #, amount, or date — easy to ignore.
Empty threats — mentioning small claims you won't pursue weakens every future message.
Inventing late fees your contract never specified.
No paper trail — chasing by phone only, with nothing saved for a formal claim.
Example Trigger Phrases
"A client is 3 weeks late on a £2,000 invoice — write me the reminders."
"How do I chase an unpaid invoice without losing the client?"
"They keep promising to pay and don't. What's my next message?"
"Invoice is 45 days overdue and they've gone silent — what now?"
"Write a firm final notice before I take this to small claims."
