What Makes a Good Assignment Description?

Before an assignment starts, you record the assignment description together with the client. This document shows that you, as a self-employed professional (ZP'er), genuinely work independently, and are not, in fact, employed. Below are the key points.

Describe a concrete result
Record what you deliver, and when. Don't use vague language such as "supporting with" or "contributing ideas on." Name a clear goal, with intermediate steps and a deadline. This makes it clear when the assignment is complete.

Choose your own way of working
Determine yourself how, where, and when you work, within the boundaries of the assignment. Do you nevertheless work fixed hours or at a fixed location? Then explain why that is necessary for this specific assignment.

Remain independent within the team
Are you working together with a team? Make sure your assignment is a distinct, recognisable part of it. Avoid blending into the organisation like a permanent employee.

Arrange for substitution
Can you be replaced by someone with the same knowledge and skills? Record this. Is that not possible? Then give a good reason.

Substantiate your rate
Your rate should match your knowledge and experience. Is your rate below the statutory minimum threshold? Then you run the risk that the law assumes you have an employment relationship.

Check your entrepreneurship
Do you work for multiple clients? Do you invest in your own equipment, insurance, or training? Things like this strengthen your position as a self-employed professional.

Finally
A good assignment description protects both you and the client. Are you unsure about a particular element? Then contact your intermediary or the client, before the assignment starts.
