What it does
Late Invoice Chaser is an agent skill from mohitagw15856/pm-claude-skills. 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.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Documents & Office, covering Forms and invoices. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked to chase an unpaid invoice
- My client hasnt paid
- Write a payment reminder
- How do I get a late-paying client to pay
Example prompts
- “/late-invoice-chaser”

What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Late Invoice Chaser loads about 1.2k tokens when it runs. Until then it costs about 134 tokens; SKILL.md has 672 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- 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.
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.

Chasing: invoice [#] · [amount] · due [date] · [N days overdue] · [relationship]
Send schedule
| When | Step | Tone |
|---|---|---|
| Due +1–3 | Gentle nudge | Assume oversight |
| Due +7–10 | Firm reminder | Clear, specific pay-by |
| Due +14–21 | Final notice | Consequences named |
| Due +30 | 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."
