B2B calling in Wallonia means calling a region of small and mid-sized companies, spread over five provinces and 261 municipalities, almost always in French. Statbel counts 3,704,990 residents on 1 January 2025, and IWEPS counts 290,082 VAT-registered SMEs at the end of 2022, which is 99.9% of all enterprises in the region. Most of the people you reach are owners. The bigger buying centres sit in logistics around Liège, in life sciences in Walloon Brabant and in industry along the Sambre and Meuse valley.
The economy of Wallonia
Wallonia produced a GDP of 136 billion euro in 2023, 23% of Belgium's total, and counted 1,344,350 jobs located in the region (IWEPS, Chiffres-clés 2025). Fewer jobs than working residents: many Walloons commute to Brussels and to Luxembourg.
Three clusters shape the region for a caller:
- Logistics around Liège. Liège Airport handled 1,324,579 tonnes of cargo in 2025, 14% more than in 2024 and its second-best year ever. The Port of Liège, the largest inland port in Belgium, recorded 16.4 million tonnes of traffic by water, road and rail in 2025. AWEX counts about 3,000 logistics companies with about 50,000 professionals in Wallonia.
- Life sciences. AWEX counts more than 300 life sciences companies in Wallonia. Eurostat shows 15,825 people working in 56 local units of the pharmaceutical industry in 2024: few sites, large buying teams.
- Industry and construction. Manufacturing has 9,803 local units with 126,538 people working in them, and construction 32,704 local units with 90,096 people (Eurostat, 2024).
By number of establishments, the Eurostat business statistics put professional services first with 43,964 local units, followed by trade with 40,908 and construction with 32,704. Staffing agencies employ 41,032 people. Agriculture and public administration are not in that dataset, so the chart above covers the business economy only.
Where the companies are
- Liège (197,323 residents in the city, 505,230 in the agglomeration, IWEPS 2025): the airport, the port, metal and engineering firms, and the services that serve them.
- Charleroi (205,763 residents, the largest Walloon city): industry, aviation around Brussels South Charleroi Airport, construction and wholesale.
- Namur (115,029): the regional capital, with the Walloon administration, federations and advisers around it.
- Mons (97,120) and the rest of Hainaut: SMEs in construction, logistics and trade, with ties to northern France.
- Walloon Brabant: Louvain-la-Neuve, Wavre and Braine-l'Alleud, home to life sciences, tech and the head offices of many service firms.
- Province of Luxembourg: rural, with many small firms and a strong pull towards the Grand Duchy.
Who to call and what to ask
In most Walloon SMEs the managing director, the gérant or administrateur délégué, decides and often owns the company. At industrial and logistics sites you also need:
- Site manager or directeur d'exploitation: operations, maintenance and safety.
- Purchasing manager: contracts above a set amount.
- HR manager: staffing, training and workwear.
- Finance manager: leasing, insurance and financing.
Discovery questions that fit Wallonia:
- Is the decision taken here, or at a group head office in Brussels, Flanders or abroad?
- How many sites do you run in Wallonia, and do they buy separately?
- Do you work with Walloon or European support schemes for this kind of investment?
- Do your customers sit mainly in Belgium, or also in France, Luxembourg or Germany?
- When does your current contract for this end, and who reviews it?
Write the script in French from the start rather than translating it from Dutch or English. Our guide to writing a cold calling script gives you the structure.
Calling in Wallonia: language, networks and rules
Language. Wallonia is French-speaking. Call in French, use vous, and expect a slightly more formal first call than in Flanders. The German-speaking Community covers nine municipalities in the east of the province of Liège, around Eupen and Sankt Vith. There, call in German. Companies near Brussels or with Flemish customers often speak Dutch or English too, but let them offer it.
Where owners meet. The chambers of commerce, such as AKT-CCI Liège-Verviers-Namur, run networking events across the provinces. UCM represents the self-employed and SMEs, the Walloon counterpart of UNIZO. In East Belgium, the WFG Ostbelgien connects local entrepreneurs. Use these networks to understand local priorities before you call.
Rules. Belgian rules apply across Wallonia. Before you call, check every number against the Ne m'appelez plus list, Bel-me-niet-meer in Dutch. It also covers business numbers, and you may not call numbers on it or people who have objected. This is general information, not legal advice. See our guide to cold calling rules in Belgium and the Netherlands.
