Where paying customers actually come from
Plumbing work in Belgium is booked by a mix of local and online routes. Neighbours and friends produce steady small jobs for repairs and installations. Private landlords and tenants ask for quick fixes. Property managers and small building owners need regular repairs. Local shops, cafes, and offices call for urgent or routine maintenance. Schools, residential care homes and small social housing managers require planned jobs too, though those clients often buy through procurement processes.
Online search and marketplaces bring customers who look for a plumber by town and service. Word of mouth is important: a reliable job at a reasonable price spreads among nearby households. Leave-behind business cards, a clear profile page you can send, and a presence on local handyman or trade marketplaces will help people find you when they urgently need a leak fixed or a boiler serviced.

How to set a first price and talk about money
Start with simple rules: estimate your labour time, add material costs, and include a margin for travel and incidental expenses. For small repair jobs consider a fixed price so the customer knows the total up front. For longer installs or uncertain problems, give a written estimate that separates labour and parts and states how you will handle unforeseen work.
When discussing money, be clear and professional. Say what is included, the expected timeframe, and how you accept payment. Ask for a deposit for larger jobs. Put terms in writing on an estimate or invoice so there are no surprises. If a customer asks for a lower price, explain trade-offs such as lower guarantees or slower scheduling. Avoid vague verbal promises about total cost.
- - estimate time, list materials, add travel/overheads
- - use fixed price for small jobs, written estimate for larger jobs
- - ask for a deposit on bigger installations
- - state payment methods and invoicing terms clearly
What the first ten customers usually look like
Your first ten paying customers will often be people you already know or who live very nearby. Expect calls from neighbours, friends’ contacts, your landlord or a local shop owner. You may get one or two jobs posted on marketplaces from people seeking a single repair. Some jobs will be small and fast, others will take longer than expected. Treat every early customer as a reference: do clean work, leave the site tidy, and ask permission to use a before-and-after photo for your profile.
Keep records of what you did, the time spent and the materials used. These early customers give you feedback on pricing, realism of estimates and how long jobs actually take. Use that information to adjust future quotes and to write short, factual descriptions of completed services on your profile page.

- - single-job marketplace customers
- - landlords and small local businesses

What to sort out when taking money as an independent person in Belgium
You must handle registration, invoicing and social contributions correctly. In Belgium you register your activity with the Crossroads Bank for Enterprises - Banque-Carrefour des Entreprises (KBO/BCE) to obtain your enterprise number. For VAT questions and registration rules, check with SPF Finances (the Federal Public Service Finance). For social security and contribution obligations check with a social insurance fund for self-employed people. If you are unsure about which legal status or tax regime fits your situation, consult a bookkeeper or accountant.
In practice you will need to issue invoices that include your business registration number and, if you are VAT-registered, your VAT number. Ask the authorities or a professional what details must appear on invoices and what records to keep for taxes. If you accept card payments through a platform, make sure you know how payouts are reported and where they appear for your bookkeeping.
- - register with the Crossroads Bank for Enterprises (KBO/BCE)
- - check VAT registration and rules with SPF Finances
- - register with a social insurance fund for contributions
- - confirm invoicing content and record-keeping with a professional
What tends to go wrong in the first months
Common issues are underquoting jobs, poor communication about times and costs, missing parts or tools on site, and late or informal invoicing. Underquoting happens when you underestimate time or material cost; it reduces profit and causes stress. Poor scheduling or unclear payment terms leads to unpaid or disputed bills. Administrative problems arise if you start without proper registration or do not track income for taxes and social security.
To avoid these, set realistic time buffers, carry a basic kit, confirm estimates in writing, ask for deposits on larger jobs and issue invoices promptly. Keep a simple ledger of jobs, hours and receipts. Build a short checklist to run before leaving the workshop so you take the right parts and tools.
- - underquoting and time underestimation
- - unclear payment terms and late invoicing
- - missing parts or wrong tools on site
- - starting without proper registration or records
How a Websta profile fits into this
A Websta profile provides a single page you can send to customers that lists your services, prices, photos, a contact form and online booking. The marketplace helps people nearby find providers by service and place and lets customers post tasks for providers to offer on. Card payments from customers are paid out to the provider’s own bank account through Stripe. You set the prices you advertise.
Use the profile as a professional point of contact: share the link in messages, include it on business cards and refer customers to your service list and booking slots. Keep the page up to date with accurate service descriptions and recent photos. Remember that a profile is a tool to be combined with reliable work, clear communication and correct administration; it does not guarantee clients or income.
- - a shareable page with services, photos and booking
- - marketplace where nearby people can find you and post tasks
- - card payments routed to your bank account via Stripe
- - you control the prices you display
Frequently asked questions
- Do I need to register to do occasional plumbing jobs in Belgium?
- Yes, you should register your activity with the Crossroads Bank for Enterprises - Banque-Carrefour des Entreprises (KBO/BCE). If you are uncertain about occasional work versus regular activity, check with KBO/BCE and a tax advisor about the appropriate registration and tax treatment.
- How should I invoice a private customer?
- Issue an invoice that includes your enterprise number and, if applicable, your VAT number. State the work performed, the date, the total and payment terms. Confirm specific invoicing requirements with SPF Finances or your accountant.
- Can I accept card payments from customers?
- Yes. A platform such as Websta uses Stripe to pay out card receipts to the provider’s own bank account. Make sure you record these payments correctly in your bookkeeping and check how they appear on your bank statements for tax reporting.
- What is the best way to find the first customers?
- Start with neighbours, friends and local contacts, list your services on a profile page you can share, join local online marketplaces and ask satisfied customers for referrals. Treat early jobs as references and collect before-and-after photos to show your work.
