Example session with this skill installed
I just started freelancing as a web designer in Ireland and I'm VAT registered. Set me up an Excel invoicing system — I bill clients here, some B2B clients in Germany and France, and one in the US. I need it to handle the VAT correctly, track who hasn't paid me, and show my profit. My business is "Pixel & Co", VAT number IE1234567T, and I want invoices numbered INV-2026-0001 with 30-day terms.
- Read your context and instructions
- Compiled the invoice builder global
A ready-to-use Excel workbook (.xlsx) tailored to Ireland: EUR currency, 23% VAT default with reduced rates available, DD/MM/YYYY dates and the correct mandatory invoice fields. It contains up to 12 linked tabs:
- Start Here, Business Info and Tax Settings (pre-filled for Pixel & Co / Ireland)
- Customers — add each client once; the workbook auto-applies the right tax treatment: 23% for Irish clients, 0% reverse-charge for the German/French B2B clients, 0% zero-rated for the US client
- Invoice — pick a customer, add line items, and VAT calculates itself; print or export to PDF
- Invoice Register, Tax Summary (VAT by rate and month), Aged Receivables (who's overdue), Dashboard (invoiced/paid/outstanding), Credit Notes and Profit Breakdown
Every total is a live formula, verified with zero formula errors, and works in Excel, Google Sheets, Apple Numbers and LibreOffice — no macros.
Connects securely to your tools. The creator never sees your data.
About this skill
What it does
This skill generates a professional, country-aware invoicing system as a live Excel workbook. It eliminates the need for manual spreadsheet creation by building a formula-driven environment tailored to your specific country's tax laws, currency, and date formats. It doesn't just create a template; it builds a full business management system (up to 12 tabs) including invoice generators, tax summaries, aged receivables tracking, credit notes, and a profit dashboard. Built for freelancers, sole traders, agencies and small companies invoicing customers anywhere in the world.
Why use this skill
Prompting an AI to "make an invoice sheet" often results in broken formulas or generic layouts that ignore local tax compliance. This skill uses a specialized Python engine to bake complex logic—like EU reverse-charge rules, GST/VAT splits, and B2B vs. B2C tax treatment—directly into the workbook. It ships with built-in rules for 40+ economies and researches any country not on the list when your workbook is built, so it works wherever you are. The resulting file works universally across Excel, Google Sheets, and Apple Numbers without requiring risky macros.
Supported features
- Global Compliance: Automatic lookup for VAT/GST/sales-tax rates, tax ID labels, date formats and regional invoice requirements for 40+ countries — and on-the-fly research for any country not pre-loaded.
- Smart Tax Treatment: Automatically applies domestic, EU B2B reverse-charge, or zero-rated export rules based on each customer.
- Automated Ledger: An Invoice Register that automatically feeds the Tax Summary, Aged Receivables and financial Dashboard.
- Receivables Management: Track who owes you money and how overdue each payment is, with ageing buckets.
- Multi-Currency Ready: Invoice in any currency, with a dedicated FX tab to record and update your exchange rates.
- Formula-First Design: All logic is transparent and live; no hidden scripts or hardcoded results.
Rates and rules are set for your country when the workbook is built; tax law changes, so confirm with your accountant before filing. This is a tool, not tax advice.
- Tax rates and rules are set at build time from a 40+ country reference (or researched for others). Tax law changes — confirm current rates with your accountant before filing.
- Multi-currency is "record your own rates": you can invoice in any currency and log FX rates on the FX tab, but the workbook does not auto-convert mixed-currency invoices into a single consolidated base-currency total.
- It is not connected to your bank or accounting software. You log each finalised invoice on the Invoice Register (one row) — there are no macros or automation buttons, by design, so the file stays safe and portable.
- Complex local regimes are simplified: US sales tax (per state/locality), Canadian provincial tax, Brazil's layered taxes and India's CGST/SGST split are handled at a practical level — set the rate per customer where needed.
- It does not generate government e-invoicing files or submissions (e.g. PEPPOL, ZATCA, FatturaPA, e-Faktur). It produces a professional invoice you print or export to PDF.
- One business per workbook.
