Frequently asked questions
Do these ideas work everywhere in Belgium?
Sheets mark Belgium when the idea applies there. Use the region filter (Wallonia, Flanders, Brussels) if you want to stay local. Exact rules (flexi-job, status, caps) depend on your situation: see the rules guide.
Do I need a special status?
Not always. Some gigs go through an employer or platform; others stay occasional. The rules guide summarises the general framework in Belgium and France. Also read the chosen sheet before you commit.
How should I read the earnings figures?
Each sheet gives an indicative range based on time and context. It is not a guarantee. Compare a few ideas and test one on a small scale first.
