Frequently asked questions
Who is Billex built for?
UK sole traders and freelancers who need to invoice clients, track what they're owed, and keep a running estimate for tax — without the overhead of full accounting software.
Do I need to be VAT registered to use it?
No. VAT and company number fields are entirely optional — most sole traders on Billex have neither, and invoices look correct either way.
Can I try it before paying?
Yes — the Free plan has no time limit and no card required. It's capped on invoices and customers rather than trial days, so you can genuinely use it, not just poke at it.
What if I need help getting started?
The How to use page walks through every part of the app step by step, and you can always reach a real person from the Contact page.
