Cadobook is the business operating system for tradespeople.

Plumbers, electricians, builders, and service contractors still run their businesses on paper, WhatsApp, and memory. Existing tools are built for offices, not vans, and are too complex to adopt.

Cadobook replaces this with one simple platform: get paid faster with digital quotes and payments, automate follow-ups and job management, and instantly create an online presence discoverable by Google and AI assistants.

Questions & Answers

As answered by people managing Cert Decoder and Cadobook.

What's the story behind your product?

Cert Decoder's answer

I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.

Cadobook's answer:

We saw tradespeople running their businesses on paper, WhatsApp, and memory — losing hours every week to admin. Existing software was built for offices, not vans. So we built Cadobook: a single platform where AI does the busywork, so tradespeople can focus on what they're great at.

Which are the primary technologies used for building your product?

Cert Decoder's answer

certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

How would you describe the primary audience of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Cadobook's answer:

Tradespeople and service contractors: plumbers, electricians, HVAC technicians, cleaners, builders, landscapers, and general contractors. Typically solo operators or small teams (1-20 people) in the UK and US who want professional tools without enterprise complexity.

Why should a person choose your product over its competitors?

Cert Decoder's answer

Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

Cadobook's answer:

Competitors are built for offices, not vans. They're complex, expensive, and require training. Cadobook is built for solo operators and small crews who need speed and simplicity. AI handles the admin work. Visual workflows automate follow-ups without coding. And pricing is a fraction of enterprise alternatives.

Who are some of the biggest customers of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

What makes your product unique?

Cadobook's answer:

Cadobook is the only AI-native business platform built specifically for tradespeople. Unlike generic tools, you can create quotes and invoices by simply describing the job in plain English. Say "quote for bathroom remodel, 3 days labor plus materials" and it's done in seconds. Everything is connected: quotes flow to invoices, invoices flow to payments, and workflows automate the rest.

    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
