How to earn money as an accountant in Mons, Belgium

If you have accounting skills and live in Mons, you can offer those services to people and businesses in your city. Some accountants in Mons work this way alongside employment, others make it their main income. The work itself - tax files, bookkeeping, compliance - is the same whether you work for one employer or multiple clients. What changes is how you find those clients, what you charge them, and how you handle the practical side of being self-employed in Belgium.

Who pays for accounting work in Mons

Mons is a city of roughly 33,000 people, with a mix of small shops, trades, service businesses, and professional offices. These are your main market. A plumber, hairdresser, electrician, or small retail owner in Mons often needs someone to sort out their year-end accounts, tax declarations, or regular bookkeeping. They search locally or ask other business owners for a recommendation. Freelancers - consultants, photographers, writers - also need accounting help to file their own returns.

Online search plays a role. When a business owner in Mons searches 'accountant Mons' or 'bookkeeping services near me', they find profiles and websites. Word of mouth is still strong in a city this size - if you do good work for one shopkeeper or small business, they tell others. Some accountants get work through existing professional networks or by being visible in business groups.

Schools and larger employers in Mons use accountants too, but they usually contract established firms rather than solo practitioners. Your first clients are more likely to be sole traders, micro-businesses, and self-employed people who need basic services at a reasonable rate.

Setting your first prices in Mons

Price-setting is a real challenge when you start. You need to know what accountants in Mons actually charge - not what a big city charges, and not what you think seems fair. Talk to other accountants if you can, or look at what established local practices list for similar work. Check what Websta profiles in your area show, if any accountants are using the platform.

A first client in Mons probably expects to pay less than a long-established practice, but not nothing. If you quote too low, you train them to expect low prices and you exhaust yourself. If you quote too high, they hire someone else. Start by hourly rate or by fixed fee for defined work - a tax return, a set of monthly books, a year-end audit for a small sole trader.

Your costs matter: Belgian accountant software (tax software, bookkeeping tools), possibly professional indemnity insurance, bank fees, and your own time spent on administration. Factor these in before you quote. As a new accountant with fewer clients, you might charge less per hour than you will later, but still enough to cover your actual costs and time.

Money and self-employment in Belgium

Before you take payment from your first client, you need to sort out your status as a self-employed person in Belgium. This is not optional. The specific rules - whether you register as a sole trader, what you declare to the tax office, what social contributions you owe - depend on whether you are doing this as a side income, full-time, or somewhere in between. You must check with your local commune or the Belgian tax office (SPF Finances), because the rules change and depend on your personal situation.

Websta uses Stripe to handle card payments from customers. Money paid by card goes directly to your own bank account - there is no holding period or transfer delay. You set your own prices on your profile, and you receive the full amount, minus Stripe's processing fee, which you can see in your Websta dashboard. You keep records of all payments received, as they are your income and must be reported for tax purposes.

You will need a Belgian bank account to receive payments. Stripe is straightforward to set up if you have a business registration or a clear self-employed status. Keep all invoices, receipts, and payment records - the tax office will want to see them.

Your first ten clients usually look like this

Your opening customers are rarely your ideal long-term clients. They are often people who need help urgently, have a tight budget, or found you by chance. You might get a small business owner scrambling to file a late tax return, a newly self-employed person with messy records, or someone referred by a friend who trusts you enough to try you out, even though you are new.

These first clients teach you. They show you what you are actually good at, what takes longer than you thought, and what your real prices should be. Some become regulars; many do not. In a city the size of Mons, your first ten clients might take two to four months to acquire, depending on how actively you market yourself and how much existing network you have.

Do not expect repeat business from everyone. Some pay on time, some pay late. Some ask you to do work outside your scope. Some go quiet after one project. This is normal. A few will become steady clients who call you every month or year, and those are valuable.

Common problems in the first months

Time estimates go wrong. A job that seems like two hours takes four because the client's records are incomplete, or they ask questions mid-way, or you have to dig into Belgian tax law you are less familiar with. You learn to pad your estimates after a few jobs.

Clients delay. They miss deadlines, send documents late, or forget to provide information you asked for. This pushes back your work and your invoice. Set clear deadlines and follow up in writing.

Scope creep happens: the client asks for 'just one more thing' that was not in the original agreement. Agree to it or not, but do not let it push you into unpaid work. Small changes pile up.

Cash flow is choppy. You might go two weeks without a payment, then receive three at once. If you need regular money to live on, a side income from accounting alongside a job is safer than relying on irregular client payments alone.

Finding clients is harder than doing the work. Mons is not huge, and accountants are not rare. You need visibility - a Websta profile, word of mouth, or both. Without it, you sit waiting for work.

How a Websta profile helps

A Websta profile is a simple page where you list your services and prices. Customers in Mons can find you by searching for accountants in the marketplace. You set up online booking so clients can schedule time with you, and they pay by card through Stripe, which goes straight to your bank account.

The profile is searchable in Mons and the surrounding area. It is also a link you can share - send it in an email to a potential client, post it on social media, or give it to someone who asks for your contact details. It looks professional without you building a website.

You control everything: your prices, the services you list, your photos, your description, and your availability. When a client books and pays through the profile, there is a record of it, and the money arrives in your account within one business day.

A Websta profile does not find all your clients. It is one channel, useful especially if customers search online. But combined with word of mouth and your own outreach, it gives you a visible presence in Mons for a trade where local search matters.

Making this work over time

Earning money as an accountant in Mons takes work. You do the client work, you handle the admin, you look for new clients, and you manage money coming in and going out. It is not passive and it is not fast. But if you are competent at accounting and patient with the business side, you can build a small client base in a city like Mons.

Start with realistic expectations. Your first month might bring one client. Your third month might bring three. By month six, if you have done good work and told people about it, you might have five or six clients who call on you sometimes. This is slower than it sounds until it reaches a point where word of mouth starts to work for you.

Keep your prices honest and your work quality high. In a small city, reputation spreads fast - both good and bad. Build relationships with your clients, deliver what you promise, and do not overcommit.

Frequently asked questions

Do I need to register as self-employed before I take my first client?
Yes. You cannot legally invoice clients or accept payment as an accountant without a clear self-employed status in Belgium. The exact registration process depends on your situation - whether this is part-time or full-time, and your commune may have specific requirements. Contact your local commune or the SPF Finances (Belgian tax office) before you start.
How much should I charge for accounting work in Mons?
That depends on what service you are offering - a one-off tax return, monthly bookkeeping, or a full audit - and what other accountants in Mons charge for the same work. Research local prices by asking around or checking profiles of other accountants. Start with a rate that covers your costs and time, even if it is lower than an established practice, but do not undervalue yourself. Adjust your prices as you get more experience and clients.
Will Websta bring me clients automatically?
No. A Websta profile makes you findable if someone searches for accountants in Mons, and it gives you a professional page to share with people who ask for your details. But most of your early clients will likely come from word of mouth, personal outreach, or existing contacts. The profile is useful alongside other efforts, not instead of them.
How long before I have enough clients to earn real money?
That depends on your skills, how much you market yourself, your pricing, and luck. Some accountants in Mons build a viable client base within six months; others take a year or more. Do not expect to earn a full income from this in your first few months. If you need steady income, keep your current job and build the accounting work on the side.
What happens if a customer does not pay me after I invoice them?
Payment problems are common and frustrating. Set clear payment terms in writing before you start work - for example, 'Invoice due within 14 days'. If a client delays or does not pay, contact them, follow up in writing, and consider whether the amount is worth pursuing legally. In a small city like Mons, reputation matters; word spreads. For future clients, you can ask for partial or full payment upfront if you are concerned.
