Running a plumbing business in Belgium means juggling more than pipes and fittings. You're writing quotes in Dutch for a client in Ghent, then switching to French for someone in Brussels who found you on Google and wants an urgent response about a bathroom renovation. Meanwhile, the BTW percentage needs to be on every single document, and you still haven't followed up on that boiler installation quote from three weeks ago.

Running a plumbing business in Belgium means juggling more than pipes and fittings. You're writing quotes in Dutch for a client in Ghent, then switching to French for someone in Brussels who found you on Google and wants an urgent response about a bathroom renovation. Meanwhile, the BTW percentage needs to be on every single document, and you still haven't followed up on that boiler installation quote from three weeks ago.
AI tools like ChatGPT handle exactly these kinds of admin headaches. You give it a quick description of the job, and it drafts the email, quote intro, or follow-up message in seconds. This guide gives you the prompts that actually work for the Belgian plumbing market.
The Belgian market has its own friction points. Labor costs are among the highest in Europe, which means clients scrutinise quotes carefully and often ask for breakdowns. If you're operating across the language border, a quote that arrives in the wrong language can cost you the job before the client even reads the price.
Then there's the administration: BTW/TVA compliance, Confederatie Bouw paperwork, and the growing demand for heat pump installations that come with their own EPBD documentation trail. Most solo plumbers spend 6 to 10 hours a week on admin that AI could draft in minutes. These prompts don't replace your expertise. They just remove the blank-page problem so you can send professional responses fast.

The prompts are written to remind you to include BTW details. For most renovation work on properties older than 10 years, the reduced 6% BTW rate applies. Always confirm with your accountant, and specify the rate in the prompt.
AI can help draft professional communications and reference your membership, but the official registration and documentation still go through Confederatie Bouw directly. Think of AI as your drafting assistant, not a registration service.
ChatGPT (free version) works fine for all of these. You can also use Claude or Microsoft Copilot. None of them require a paid plan for basic prompt use.
