What it does
Invoice Generator is an agent skill from mohitagw15856/pm-claude-skills. Create a professional, complete invoice for a client or customer. Use when asked to write an invoice, create a bill, draft a freelance/contractor invoice, or set up an invoice template. Produces a clear invoice — your and the client's details, a unique number, line items with quantities/rates, subtotal/tax/total, payment terms and methods, and due date — ready to send and easy to pay. Not tax/legal advice.
Its SKILL.md is about 1k 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 write an invoice
- Draft a freelance/contractor invoice
- Set up an invoice template
Example prompts
- “/invoice-generator”
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
Invoice Generator loads about 1k tokens when it runs. Until then it costs about 107 tokens; SKILL.md has 516 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.

- invoice-generator
- description
- Create a professional, complete invoice for a client or customer. Use when asked to write an invoice, create a bill, draft a freelance/contractor invoice, or set up an invoice template. Produces a clear invoice — your and the client's details, a unique number, line items with quantities/rates, subtotal/tax/total, payment terms and methods, and due date — ready to send and easy to pay. Not tax/legal advice.
Invoice Generator Skill
An invoice that's clear and complete gets paid faster — it has the details a client (and their finance team) need to approve and pay without a back-and-forth. This skill produces a professional invoice with everything in the right place: itemised work, the totals, and how and when to pay.
Note: this is a documentation aid, not tax, accounting, or legal advice. Tax handling (VAT/GST/sales tax, reverse charge, withholding), required fields, and registration numbers vary by country and situation — confirm your tax treatment and legal requirements with an accountant. Tax lines below are flagged to set.
Working from a brief
Given "invoice a client $2,000 for a website project", produce the full invoice anyway — lay out every standard field and mark the ones to set (your detail) (invoice number, dates, tax rate, payment details). Compute the arithmetic from the line items you're given; don't invent a tax rate — flag it to set.
Required Inputs
Ask for these only if they aren't already provided (else mark to set):
- From / to — your business name + contact (and tax/registration ID if applicable), and the client's billing details.
- Line items — description of work/goods, quantity, unit rate.
- Tax — whether tax applies and the rate (flag to confirm), or exempt/not applicable.
- Terms — payment due (e.g. Net 30), accepted methods (bank transfer, card, etc.), and any late-payment terms.
- References — PO number, project name, invoice number (or note your numbering scheme).
Output Format
Invoice
- Header — "INVOICE", a unique invoice number, issue date, and due date.
- From — your business name, address, contact, tax/registration ID (if any).
- Bill to — client name, address, contact; PO/reference if provided.
- Line items — a table: description · qty · unit rate · amount.
| Description | Qty | Rate | Amount |
|---|
- Totals — subtotal, tax (rate + amount, flag to set), discounts if any, and total due (in the right currency). Show the arithmetic so it's verifiable.
- Payment details — how to pay (bank/account details, payment link, etc.) and the terms (due date, late fee if any).
- Notes — a short thank-you / any terms; and a reminder to confirm tax treatment with an accountant.

Quality Checks
- Has a unique invoice number, issue date, and explicit due date
- Both parties' details are complete (and tax IDs where relevant)
- Line items are itemised and the subtotal/tax/total arithmetic is correct and shown
- Payment method(s) and terms (e.g. Net 30) are clear
- Currency is explicit; tax rate is flagged to set rather than assumed
- Reads professionally and is easy for a finance team to approve
Anti-Patterns
- Do not invent a tax rate or tax treatment — flag it to confirm with an accountant
- Do not omit the invoice number or due date — they're what makes it trackable and payable
- Do not leave payment instructions vague — say exactly how to pay
- Do not miscompute totals — show the math so it can be checked
- Do not present this as tax/legal advice — it formats an invoice, it doesn't certify compliance
Based On
Billing & accounts-receivable practice — complete, itemised invoices with clear terms and payment instructions (tax treatment left to a qualified accountant).
Example Trigger Phrases
- "Write an invoice."
- "Create a bill."
- "Draft a freelance/contractor invoice."
- "Set up an invoice template."
