Frequently asked questions
Is the invoice generator really free?
Yes — completely free, with no sign-up and no hidden limits. It runs in your browser, so we never even see your data.
Do I need to be a registered sole trader to use the tools?
No. The tools work for anyone invoicing clients — freelancers, side-hustlers and established sole traders alike.
How much should I charge as a UK freelancer?
It depends on your field — our free guide has current UK market rates by field and a simple formula for working out your own rate. See the freelancer charging guide.
How do I pay for the Starter Pack or Setup service?
Ordering is simple: email us from the products page (or use our payment link once it's live) and we'll send your files within 24 hours. Full details are on the products page.
Are the tax figures up to date?
The pricing calculator uses current UK income tax bands and Class 4 National Insurance rates. It's an estimate, not accounting advice — see the disclaimer on that page.
