Common questions from self-employed people

Is this suitable for sole traders?
Absolutely! Invoicer is perfect for sole traders and self-employed people. It's simple enough that you don't need an accountant to set it up, but professional enough to impress your clients.
Can I use it for my tax return?
Yes. Your dashboard shows your total income and what's still outstanding, and you can download your invoices as PDFs - one at a time or several at once in a single zip file. That gives you the paperwork and the figures for your Self Assessment.
What if I'm not VAT registered?
That's fine! Just turn off the VAT setting and your invoices won't show VAT. You can enable it later if you register for VAT.
Do I need to be tech-savvy?
Not at all. If you can send an email, you can use Invoicer. We've kept it deliberately simple because we know most self-employed people just want to get their invoicing done, not learn complicated software.
Is there a contract?
No contracts. No lock-in. Cancel anytime in seconds. We know self-employed people need flexibility.

Not your trade?

Invoicer is set up just as well for gardeners and landscapers, electricians, plumbers and heating engineers, builders, older tradespeople who want big, clear screens, members of trade schemes and anyone invoicing from a phone.
