Software Development & Web Design in Charleroi
Création de site web, software and app development for Charleroi's airport, aerospace, industrial and retail businesses, in French and English, delivered remotely from Bucharest.
Charleroi, with about 202,000 residents, is the largest city in Wallonia. Its former steel and glass heartland has turned to aerospace, biotech and the Aéropole near the Brussels South Charleroi Airport, while a regenerating centre draws new commerce.
What a business in Charleroi has to get right
Charleroi is French-speaking, and Walloon firms often sell to Flanders too. Belgian business sites need the company details and VAT number shown on the site, and cookie consent handled under the Data Protection Authority (APD/GBA) rules. B2B e-invoicing through Peppol has been mandatory between Belgian VAT-registered businesses since 1 January 2026.
