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
