Where paying customers come from
Local demand for plumbing work is spread across several predictable places. Neighbours and apartment buildings create steady small jobs - clogged drains, leaking taps, replacing valves. Workplaces and local shops need occasional repairs and maintenance. Schools, small businesses and landlords look for reliable quick fixes and routine checks. Online search and local marketplaces are increasingly how strangers find you, especially for jobs outside your immediate area. Word of mouth and repeat clients often provide the most reliable flow once you have a few jobs done well.
Actively search in the places you can reach easily. Knock on doors in apartment blocks where permitted, leave a simple card with contact details, join local online groups on social platforms, and ask satisfied customers for referrals. Small regular customers such as a family-run cafe or the janitor in an office building can lead to repeat work.
- Neighbours and apartment blocks - quick fixes and small repairs
- Landlords and property managers - recurring maintenance
- Local shops, schools and workplaces - scheduled maintenance and emergency calls
- Online search and marketplaces - one-off jobs from outside your immediate area
- Word of mouth and referrals - the most stable source over time
How to set a first price and talk about money
Start by covering your costs: materials, travel, tools and the time you spend. For common small tasks you can use simple fixed fees so customers know the cost up front. For uncertain jobs use an hourly rate or a written estimate. Before you give a final price, inspect the job and explain what is included and what might add cost.
When talking money, be clear and short. Give a written estimate for anything beyond a simple job. If a job may take longer than expected, state that additional work will be charged separately and get agreement. For larger repairs ask for a deposit or staged payments. Keep receipts and document extra parts purchased.
- Calculate materials + travel + reasonable pay for your time
- Use fixed prices for repeatable tasks and estimates for complex work
- Provide written estimates or invoices for transparency
- Ask for a deposit on larger jobs
What the first ten customers usually look like
The first ten customers often come from your existing network or very local sources. Expect friends, family, neighbours, previous employer contacts, and small landlords. You may also pick up a few one-off jobs from local shops or online classifieds. These early customers tend to be small jobs that let you build references: unclogging drains, fixing a leaking toilet, swapping a faucet, or replacing a water heater part.
Treat these first jobs as both income and proof of reliability. Deliver on time, keep communication simple, and ask permission to photograph the completed work and collect a short testimonial. Those items will help you get more clients later.
- Friends and family - low-hassle first jobs
- Neighbours - quick calls for common issues
- Small landlords and shops - repeat opportunities
- Online leads - variable but useful for variety
What to sort out when taking money as an independent person
In Czechia you need to check registration and tax obligations before you start offering paid services. Contact the local Živnostenský úřad to ask how to obtain trade authorisation (živnostenské oprávnění) for plumbing. Ask ČSSZ (Česká správa sociálního zabezpečení) about social insurance registration and your obligations as an OSVČ. For tax and VAT questions contact the Finanční správa and ask what records and invoices you must keep and whether you need to register for VAT.
Also check with your health insurance provider about compulsory health insurance contributions for self-employed people, and ask an insurer about liability insurance for tradespeople. For the practical side of payments decide which methods you will accept and how you will document them. Card payments from customers are paid out to the provider's own bank account through Stripe; the provider sets the prices. Confirm with the authorities what paperwork you must issue to customers and how to declare such income.
- Ask Živnostenský úřad: how to register and what trade authorisation you need
- Ask ČSSZ: when to register for social insurance as an OSVČ
- Ask Finanční správa: invoicing rules, record keeping, and VAT obligations
- Ask your health insurer and an insurer about contributions and liability insurance
What tends to go wrong in the first months
Common early problems are underestimating job time, not carrying the right spare parts, unclear payment terms, and poor scheduling. Underpricing to win work is a frequent mistake that makes it hard to cover costs. Communication breakdowns with customers cause disputes about what was included. Not documenting work and payments creates tax and accounting headaches later.
Prevent these issues by preparing a basic toolkit of common parts, writing clear estimates, setting simple payment terms, and keeping a diary of jobs and receipts. Plan realistic travel time between calls and allow extra time for diagnostics.
- Underestimating time and materials
- No spare parts for common fixes
- Unclear written terms leading to payment disputes
- Poor diary and record keeping
How a Websta profile fits into your work
A Websta profile acts as a simple public page you can send to anyone: it shows services, photos, a contact form and online booking so customers can see what you offer and book directly. You can list typical jobs and set your own prices on the profile. Card payments from customers are paid out to the provider's own bank account through Stripe; the provider sets the prices. Use the page as a single link to share in messages, on flyers, or on social media.
A profile does not replace official registration, record keeping or insurance. It is a tool to be found and to receive enquiries and bookings. Be honest in listings, keep photos and prices up to date, and use the profile together with proper invoices and records for tax purposes.
- Send one page to potential customers with services and booking
- Collect online bookings and card payments through Stripe
- Keep listings accurate and use the profile alongside official paperwork
Frequently asked questions
- Do I need a trade licence to work as a plumber in Czechia?
- You should contact your local Živnostenský úřad to confirm whether plumbing work requires a specific živnostenské oprávnění and how to register. Ask what documentation is needed to offer paid services legally.
- Can I do plumbing work alongside a job?
- Yes, many people start plumbing as a side activity. Check with Živnostenský úřad, ČSSZ and your health insurer about how additional income affects social and health insurance contributions and any reporting requirements.
- How should I accept payments from customers?
- Decide on payment methods you can manage and document. Websta supports card payments that are paid out to your own bank account through Stripe; you can also accept cash or bank transfers. Ask Finanční správa what records and invoices you must keep for tax purposes.
- Should I insure my plumbing work?
- Liability insurance for tradespeople reduces risk from damage or injury. Contact an insurer to ask about public liability insurance and what it covers for plumbing work.
- How do I set prices for common jobs?
- Cover materials, travel and your time. Use fixed fees for repeatable tasks and written estimates for complex jobs. Test your pricing with local customers and adjust to ensure you cover costs and time.
