See it in action
A freelance graphic designer finishing a logo project needs a clean invoice to email a client the same afternoon.
What you type
From: me (sole trader, ABN 12 345 678 901). Bill to: Acme Cafe. Work: logo design 8 hrs @ $95, plus 2 rounds of revisions $180. Due in 14 days.
What you get
TAX INVOICE Invoice #: 0042 Date: 27/08/2026 Due: 10/09/2026 Bill to: Acme Cafe Logo design (8 hrs @ $95.00) $760.00 Revisions (2 rounds) $180.00 Subtotal $940.00 GST (10%) $94.00 Total $1,034.00 Payment: bank transfer to BSB / Acc [your details] · Ref: INV-0042
Tip: Tell it whether you're registered for GST — under the $75k threshold a sole trader mustn't charge it, and an invoice that wrongly adds 10% can cost you the client's trust or a refund. Add your payment terms and a reference line, because invoices without a clear due date and a BSB get paid slowest.

FAQ
Frequently asked questions
Is the invoice it produces legally compliant?
It follows standard conventions (itemised services, dates, totals, payment terms) and leaves placeholders for the details only you can supply: your business number, tax registration, and the tax treatment that applies to you. Requirements differ by country and business type, so check what your tax office expects (in Australia, whether it must be a tax invoice showing GST) before it goes out.
Does it calculate the totals for me?
It will add lines and apply the percentages you specify, but arithmetic is a known weak spot for AI, so run every figure past a calculator before sending. The sensible split: let the tool handle layout, item descriptions and wording, and treat the numbers as yours to confirm. A wrong total costs more credibility with a client than a plain-looking invoice ever will.
Can it match the invoice numbering I already use?
Tell it your format and the next number in your sequence (INV-2026-041, say) and it slots it in. What it cannot do is track the sequence for you, because nothing carries over between sessions. Keep your own register of issued numbers, even a simple spreadsheet, so you never send two clients the same invoice number.
Is it safe to paste client names and amounts in here?
Nothing you enter is stored once the tab closes and sessions aren't used for training, though prompts are processed by third-party AI providers under their own terms. For everyday invoicing that's a reasonable trade. Where a client relationship sits under an NDA, draft with initials or placeholders and drop the real details into your copy afterwards.
How should I word the payment terms so I actually get paid on time?
Name a specific due date rather than vague phrases like 'payment on receipt', state the accepted payment methods, and if you charge late fees, say so plainly on the invoice itself. Ask the tool for firm-but-polite terms and it will draft wording that sets expectations without souring the relationship, clear terms up front beat awkward chasing later.
Is there a free invoice generator with no sign up?
Yes. List your services, amounts and client details and get a clean invoice for free, with no account or email needed. There is nothing to install. Itemizing each service, quantity and rate separately gives you a clear breakdown your client can check at a glance.
What information must an invoice include?
A proper invoice shows your details, the client's, a unique invoice number, the date, an itemized list of services with amounts, the total, and payment terms. Tax details go on too if you charge it. This tool lays those out so nothing that matters is missing.
Can I add tax or GST to the invoice?
Yes. Enter your tax or GST rate and it will show the tax line and fold it into the total, laid out clearly for the client. Add your registration number if your invoices need to display one. Always check the final figures against your own records before sending.
What are the usage limits?
Business tools are unmetered text tools during the current free launch phase, build every document a plan needs. A short per-minute limit exists solely to prevent automated abuse. Paid plans with higher limits and priority model access are coming soon.
