How to Write a Convincing Business Plan in Belgium

A business plan is a strategic document that describes your entrepreneurial project, analyses its market, details your strategy and projects your financial results. In Belgium, it is essential in several situations: obtaining a bank loan, convincing investors, applying for regional grants, or simply structuring your thinking before you launch. For companies (SRL, SA, SC), the financial section of the business plan feeds directly into the mandatory financial plan that must be handed to the notary when the company is incorporated. This guide walks you step by step through writing a solid business plan, adapted to the Belgian context.

Why write a business plan in Belgium

For yourself

A business plan is first and foremost a personal thinking tool. It forces you to structure your idea, test your intuitions against real data, and anticipate difficulties. According to a Harvard Business Review study, entrepreneurs who write a business plan are 16% more likely to succeed than those who do not.

For the bank

In Belgium, banks (BNP Paribas Fortis, ING, KBC/CBC, Belfius, Crelan, and others) systematically require a business plan for any business loan. The credit department assesses the file against standardised criteria:

• Viability of the project and the market
• Repayment capacity (projected cash flow)
• Guarantees offered (personal surety, pledge, mortgage)
• Experience and skills of the project's founder
• Personal contribution (banks generally require own funds covering 20% to 30% of the total financing need)

For investors

If you are seeking private investors (business angels), venture capital funds or crowdfunding, the business plan is your tool of persuasion. Belgian business angel networks (BeAngels, BAN Vlaanderen, EBAN) receive hundreds of applications a year. A clear, well-structured business plan is your ticket in.

For grants and public support

Belgian public bodies make their support conditional on presenting a business plan:

• SOWALFIN (Wallonia): for subordinated loans and public guarantees
• Invest.brussels / finance.brussels: for loans and equity investment in Brussels
• PMV (ParticipatieMaatschappij Vlaanderen): for Startlening loans and subordinated loans in Flanders
• Chèques-entreprises (Wallonia): to justify the support requested
• VLAIO (Flanders): for SME grants and innovation premiums

For the notary (mandatory financial plan)

When incorporating an SRL, SA or SC, Article 5:4 of the Companies and Associations Code (CSA) requires a financial plan to be handed to the notary. This financial plan is the financial section of your business plan. It must cover at least two years and demonstrate that the starting equity is sufficient.

The typical structure of a Belgian business plan

An effective business plan generally has seven main sections, totalling 20 to 30 pages (excluding appendices). Here is the detail of each section.

1. Executive summary — 1 to 2 pages

The executive summary is the most-read and most important part. It must make the reader want to continue. In practice, it is the last section you will write, since it summarises the whole document.

Contents of the executive summary:

• Project name and chosen legal form (SRL, sole trader, etc.)
• Problem identified: What market need does your project address?
• Solution proposed: What product or service are you offering?
• Target market and estimated market size in Belgium
• Competitive advantage: Why will customers choose you over the competition?
• Business model: How do you make money?
• Key financial targets: projected turnover for years 1, 2 and 3, and the break-even point
• Financing need: amount sought and planned use of funds
• Founding team: Who is behind the project and what are the key skills?

Example executive summary:

GreenClean SRL is an eco-friendly cleaning company serving offices and co-working spaces in the Brussels-Capital Region. Founded by Marie Dupont, who has 12 years of experience in facility management, GreenClean meets Brussels businesses' growing demand for cleaning services that use exclusively Ecolabel-certified biodegradable products. The professional cleaning market in Belgium is worth EUR 4.2 billion (source: ABSU/UGBN 2024), with the "green" segment growing 15% a year. GreenClean is targeting turnover of EUR 180,000 in year 1, EUR 350,000 in year 2 and EUR 520,000 in year 3, reaching break-even in month 8. The financing sought is EUR 45,000 (a EUR 30,000 bank loan plus a EUR 15,000 finance.brussels subordinated loan), topped up with a EUR 20,000 personal contribution.

2. Presentation of the project founder — 2 to 3 pages

Bankers and investors invest in people first, and in projects second. This section must convince the reader that you have the skills, experience and motivation to carry the project through.

Elements to include for each founder:

• Professional background: a concise CV focused on the skills relevant to the project
• Education: degrees, certifications, ongoing training
• Key skills: technical, commercial, managerial, financial
• Entrepreneurial experience: previous projects, successes and lessons learned
• Motivations: Why this project? What is your vision?
• Professional network: key contacts, mentors, potential partners
• Complementary skills: if there are several founders, show how your skills complement one another
• Time commitment: Full-time or part-time? If run as a secondary activity, when is the move to full-time planned?

Tip: If you identify a gap in your profile (for example, no accounting or marketing skills), mention it and explain how you plan to fill it (external accountant, planned training, a future hire). Investors prefer an entrepreneur who is clear-eyed about their weaknesses to one who claims to know everything.

3. Description of the product or service — 2 to 3 pages

This section describes in detail what you are selling and why customers will buy it.

Recommended structure:

• Detailed description of the offer (product or service)
• Benefits for the customer (not technical features, but the concrete added value)
• Stage of development: idea, prototype, MVP (minimum viable product), finished product, already on sale?
• Intellectual property: patents, trademarks registered with the OPRI (Office de la Propriété Intellectuelle, the Belgian IP office) or the EUIPO, copyright, trade secrets
• Production or delivery process: How do you produce or deliver your service?
• Development roadmap: How will your offering evolve over the next three years?
• Pricing: detailed pricing policy (also covered in the commercial strategy)

4. Market analysis — 4 to 5 pages

This is the section that separates an amateur business plan from a professional one. A rigorous market analysis, based on verifiable data, is essential to convince your reader.

Overall market (top-down approach):

• Market size in Belgium: use data from Statbel (statbel.fgov.be), the FPS Economy (SPF Économie), Eurostat, or sector studies (Graydon, Trends Business Information, trade federation studies)
• Trends and growth: Is the market growing, stable or declining? What are the driving factors?
• Applicable regulation: What laws, standards or certifications govern your sector in Belgium? Are there regulatory changes to anticipate?
• Regional specifics: Does the market differ between Flanders, Wallonia and Brussels? (language, purchasing power, population density, consumption habits)

Target market (bottom-up approach):

• Segmentation: divide the market into relevant segments (geographic, demographic, behavioural)
• Target segment: Which specific segment are you targeting, and why?
• Segment size: How many potential customers are there in your geographic area?
• Needs identified: What problems or frustrations of this segment does your offer solve?
• Willingness to pay: How much are these customers prepared to pay for your solution?

Competitor analysis:

5. Commercial strategy — 3 to 4 pages

The commercial strategy describes how you will win customers and generate turnover.

The marketing mix (4Ps), adapted to the Belgian context:

Product:

• Range of products/services offered
• Service tiers (basic, premium, enterprise)
• Associated services (support, maintenance, training)
• Differentiation from competitors

Price:

• Detailed pricing policy
• Comparison with Belgian market prices
• Pricing strategy: penetration (low prices to win market share), skimming (high prices for a premium position), or alignment with the market
• Payment terms (under the law of 2 August 2002: a default payment term of 30 days in B2B)
• Discount policy and commercial terms

Place (distribution):

• Distribution channels: direct sales, e-commerce, distributors, sales agents
• Geographic area: local, regional, national, international
• Specifics of the Belgian market: a trilingual market (French, Dutch, German), regional differences in consumption, the importance of personal networks
• Online presence: website, marketplaces (bol.com, Amazon.be), social media

Promotion (communication):

• Communication strategy with a detailed budget
• Priority channels:
  • Digital marketing: SEO, SEA (Google Ads), social media (LinkedIn for B2B, Instagram/Facebook for B2C), email marketing
  • Networking: Belgian trade fairs (Batibouw, Brussels Expo, Flanders Expo), chambers of commerce (BECI in Brussels, VOKA in Flanders, CCI in Wallonia), entrepreneur clubs
  • Press relations: French-speaking Belgian media (L'Echo, Trends-Tendances, La Libre Entreprise) and Dutch-speaking media (De Tijd, Trends)
  • Content marketing: blog, webinars, white papers
• Estimated marketing budget (generally 5% to 15% of projected turnover)

Detailed customer acquisition plan:

6. Operational plan — 2 to 3 pages

The operational plan describes the practical aspects of your company's day-to-day running.

Business premises:

Main co-working options in Belgium: Silversquare, Fosbury & Sons, WeWork, BeCentral (Brussels), CoStation (Charleroi), StartIT@KBC (Antwerp, Ghent, Louvain), MolenGeek (Molenbeek).

Equipment and investments:

List all the investments needed to start up, with their cost and depreciation period:

Key suppliers:

• Identify your main suppliers
• Negotiate payment terms
• Plan alternatives (do not rely on a single supplier)

Human resources:

• Recruitment planning (years 1, 2, 3)
• Payroll cost in Belgium (note: the employer cost in Belgium is among the highest in Europe, with roughly 25% employer social security contributions on gross salary, on top of NSSO (ONSS) contributions, work accident insurance, holiday pay and the 13th-month bonus)
• Alternatives: outsourcing, freelancers, internships, temporary staff

Example of full payroll cost in Belgium (employee under Joint Committee 200, full-time):

7. Financial plan — 5 to 8 pages

The financial plan is the heart of the business plan. For an SRL, it is also the mandatory legal document to be handed to the notary (Article 5:4 CSA). The full detail of how to draft it is covered in our dedicated article, "Drafting the mandatory financial plan to set up an SRL in Belgium".

Components of the financial plan:

Projected opening balance sheet:

Projected income statement (3 years):

Monthly cash-flow plan (24 months minimum):

For each month, detail:

• Receipts (turnover collected, contributions, loans, grants)
• Payments (purchases, expenses, remuneration, repayments, VAT, social security contributions, taxes)
• Monthly balance and cumulative balance

Break-even point:

The break-even point is the turnover at which the company covers all of its costs.

Formula: break-even point = fixed costs / contribution margin ratio

Example:

• Annual fixed costs: EUR 60,000 (rent, salaries, insurance, accountant, and so on)
• Contribution margin ratio: 70% (a services business)
• Break-even point = 60,000 / 0.70 = EUR 85,714 of turnover
• If your daily rate is EUR 650, that represents 132 billable days to reach break-even

The three scenarios:

Every serious business plan presents three scenarios:

Crucial tip: The banker and the investor will look at the pessimistic scenario. If your cash position stays positive under the pessimistic scenario, your project is considered viable. If the pessimistic scenario shows negative cash flow, you must either increase equity or revisit your cost assumptions.

Tips for a convincing business plan

Be realistic and honest

• Do not inflate your projected turnover to impress. Experienced bankers and investors spot unrealistic figures immediately.
• Identify and mention the risks. An entrepreneur who knows their risks inspires more confidence than one who sees none.
• Cite your sources. Every market figure should be sourced (Statbel, sector studies, supplier quotes, and so on).

Be concise and well structured

• A maximum of 25–30 pages, excluding appendices. A business plan that is too long will not be read in full.
• Use charts and tables to visualise the financial data.
• Put detailed documents in appendices (full CVs, market studies, quotes, contracts).
• Use a table of contents with page numbers.
• Avoid technical jargon unless your reader is an expert in the field.

Be specific to the Belgian context

• Mention the Belgian regulations that apply to your sector
• Take account of regional specifics (Flanders, Wallonia, Brussels)
• Reference the relevant Belgian institutions (FPS departments, regional bodies, federations)
• Use Belgian data for your market analysis (not American or French data)
• Build the Belgian tax context into your financial projections (ISOC, IPP/PIT, VAT, social security contributions)

Tailor the document to your audience

Tools and templates

The most common mistakes in Belgian business plans

1. A poorly defined market

"My target market is everyone" is the worst possible answer. The more precise your segment, the more effective your strategy will be, and the more credible your business plan.

Poor: "Our target market is SMEs in Belgium."
Good: "Our target market consists of HoReCa-sector SMEs with 10 to 50 employees in the Brussels-Capital Region, roughly 2,300 businesses (source: Statbel 2024)."

2. Unrealistic financial projections

Belgian bankers have access to every company's annual accounts through the BNB's Central Balance Sheet Office. If your projected turnover is three times the sector average, they will spot it immediately.

Tip: Check the annual accounts of comparable companies on the BNB website (nbb.be/fr/centrale-des-bilans) to benchmark your forecasts.

3. Ignoring the competition

"We have no competitors" is a red flag for any investor. If nobody else is doing what you do, there may simply be no market. Always identify your competitors, even indirect ones.

4. Overlooking working capital requirements

Many entrepreneurs forget that invoiced turnover is not collected turnover. In Belgium, the average B2B payment term is 40 days (source: Graydon Belgium). If you invoice EUR 10,000 in January, you will not receive it until February or March. Meanwhile, you still have to pay your costs.

5. Underestimating the Belgian payroll cost

Belgium has one of the highest payroll costs in Europe. Total employer cost is roughly 155% of gross salary (employer contributions, holiday pay, 13th-month bonus, insurance, and so on). A gross salary of EUR 3,000 a month actually costs the employer EUR 4,500 to EUR 4,800 a month.

6. Forgetting Belgium's regional specifics

Belgium is not a homogeneous market. The linguistic, cultural and regulatory differences between Flanders, Wallonia and Brussels are significant:

• A website in French only reaches 40% of the Belgian population
• Support and grants differ by region
• Access-to-profession requirements vary (basic management knowledge in Wallonia)
• Consumption habits and purchasing power differ

Complete business plan checklist

Before submitting your business plan, check that you have covered:

• Clear, compelling executive summary (1–2 pages)
• Presentation of the founder(s) with CV and skills
• Detailed description of the product/service
• Market analysis based on sourced Belgian data
• Competitor analysis with a differentiating position
• Commercial strategy with a detailed marketing mix
• Customer acquisition plan with quantified targets
• Operational plan (premises, equipment, suppliers, HR)
• Projected opening balance sheet
• Projected income statement over 3 years
• Monthly cash-flow plan over 24 months
• Break-even point calculated
• 3 scenarios (pessimistic, realistic, optimistic)
• Detailed financing need (amount, use, repayment plan)
• Appendices (CVs, quotes, studies, contracts, letters of intent)
• Table of contents with page numbers
• Professional layout and proofreading

Conclusion

A business plan is never perfect on the first attempt. It is a living document that evolves with your project, your learning and feedback from the market. In Belgium, support resources are plentiful and often free or subsidised, so make use of them. Start by writing it, even imperfectly, have it reviewed by a professional (an accountant, a consultant, a hub.brussels or 1890 coach), and refine it gradually. A good business plan does not guarantee success, but it considerably increases your chances of convincing financial partners and, above all, of making informed decisions for your business.
