Questions from electricians

Does it handle VAT properly?
Yes! If you're VAT registered, it calculates 20% VAT, shows it clearly on invoices, and gives you totals for your VAT returns. Proper VAT invoices that meet HMRC requirements.
Can I attach my NICEIC/NAPIT certificate?
Yes. Upload your registration certificates, public liability insurance, and any other documents. Attach them to invoices when customers or contractors ask for proof.
Is it suitable for emergency call-outs?
Perfect for it. Invoice immediately from your phone while still at the customer's property. Get it sent before you leave so they can't "forget" about the bill.
Can I use it for both small jobs and big rewires?
Absolutely. From a £50 socket replacement to a £5,000 rewire - works the same way. Add multiple line items for bigger jobs.
Will it work for my trade scheme application?
Every invoice carries a unique, traceable number, a professional layout, and all your business details - the things endorsement schemes usually ask to see. Check your scheme's own requirements, as each one differs slightly.

Not your trade?
