Company and household business formation
Opening a company or registering a household business is the first decision, and the choices you make at the start stay with you throughout operations.
What you are likely facing
Not sure whether to open a company or a household business
Each form has different responsibilities, filing methods and paperwork, so it is hard to tell which suits the way you plan to do business.
Registering a business line, then finding it needs conditions
Some business lines have their own conditions or licences; finding out late means redoing your plan.
Address, capital and representative still unclear
This information goes straight into the registration file; if chosen carelessly it may need adjusting later.
Registered, but unsure what comes next
After formation there are tax, invoicing and accounting tasks that newcomers rarely have time to learn.
