Frequently Asked Questions
Invoice Guru FAQ
Is Invoice Guru really compliant with HMRC's Making Tax Digital (MTD)?
Yes, absolutely. Invoice Guru is designed from the ground up for MTD compliance.

Can I use Invoice Guru on a computer as well as my phone?
While Invoice Guru is built with a mobile-first, on-the-go philosophy for core invoicing, it offers a full-featured web dashboard.

What happens if I need to issue a quote or estimate before a job?
Invoice Guru includes full quote and estimate functionality. You can create professional, branded quotes in seconds on your phone, send them to clients, and then with one tap, convert an accepted quote directly into a final invoice, saving you from double data entry and streamlining your entire workflow from lead to payment.
