Let the AI do the rest.

Certio snaps your certs from a photo, answers your WhatsApp round the clock, wins the leads you're losing to whoever replies first, and does the invoicing — so the paperwork stops eating your evenings.

The real job

The work isn't the hard part. Everything around it is.

You're good with your hands. It's the leads, the certs, the chasing and the paperwork where the money and the evenings leak away.

📵

The lead goes to whoever replies first

A customer messages five sparkies. You're on a job, phone in the van. By the time you see it, they've booked someone else.

🌙

Certs eat your evenings

Two hours a night typing up EICRs and PATs from scribbled notes, when you should be with the family or asleep.

💸

Invoices sent late = paid late

"I'll do it Sunday." Sunday comes, you're knackered. The invoice sits in your head instead of the customer's inbox.

🗂️

Five apps that don't talk

Cert software here, invoicing there, notes on your phone, quotes on paper. Nothing joins up and everything's double-typed.

📋

Checkatrade leads slipping away

You pay for the lead, then lose it because you didn't reply within the hour. Speed wins the job — and you can't always be fast.

👷

Can't hand work to your lads

Give an apprentice your phone and they see your prices, your money, your customers. So you do it all yourself.

How Certio fixes it

Every one of those, sorted.

Not another app to babysit. An assistant that actually takes the jobs off your plate.

✕ The problem

You miss the message, you lose the job

You can't watch your phone with gloves on. Every minute you're quiet, a competitor is replying.

✓ Certio does this

An AI answers your WhatsApp in seconds — 24/7

It talks like you, in your words. It reads the photos customers send (yes, it can see the fuseboard), qualifies the job and pencils them in — even at 11pm. You wake up to booked work.

✕ The problem

Certificates take all evening

Typing up boards, circuits and readings by hand, from memory, after a 10-hour day.

✓ Certio does this

Snap a photo, get a compliant cert

Photograph the consumer unit — the AI reads the board and fills the EICR, EIC, Minor Works or PAT for you. Branded PDF, your logo, out the door in minutes. Works offline on site.

✕ The problem

Invoicing and quoting is a faff

Different app, retype everything, forget the VAT and CIS, send it three days late.

✓ Certio does this

Quote, invoice and get paid — same app

Turn a chat into a quote, a quote into an invoice, with CIS and reverse-charge VAT handled. Add a pay-by-card link. It's all joined to the job, so nothing's typed twice.

✕ The problem

You can't let staff loose in the app

Give a worker access and they'd see your margins and your money.

✓ Certio does this

Add your team — money stays yours

Your workers get the whole app to do certs and jobs, but the invoicing, quotes and prices are walled off. Their work flows straight back to you.
