Literally the best app on the market…
Literally the best app on the market for small one man bands.
The WhatsApp assistant took a bit of fine tuning but definitely worth the £10 a month.
Great work guys!

Unprompted review
While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more
Company details
Written by the company
Certio is certification, quoting and invoicing software for UK electricians, made by Certio Software Ltd. Photograph a consumer unit and Certio reads the ways, device types and ratings into your schedule of test results. It never guesses a reading: anything it can't read stays blank for you to fill in, and anything it has assumed is flagged for you to check. Tester readings come in from a photo of your tester's screen. Certio produces EICR, EIC, Minor Works and PAT certificates as branded PDFs that you sign on your phone. It also prices quotes from a drawing, raises invoices with CIS and domestic reverse charge VAT worded correctly, sends card payment links and chases unpaid invoices. Receipts, your diary and your team sit in the same app. It works offline on site and syncs when you're back on signal, and the same login works on your phone and in any web browser. There's a 7-day free trial on the Starter plan and no contract on any plan. Moving from another app? We'll load your existing certificates, customers and invoices for you, free.
