Freelance engineering offers freedom and variety, but it also brings responsibility for contracts, pricing, tax compliance, and project risk. This article is a practical guide for engineers who want to take on project work confidently.
Get the contract right
- Define the scope clearly: what you deliver, what is excluded, and how changes are handled.
- Agree on milestones, payment terms, and consequences of delay by either party.
- Include intellectual property terms and confidentiality clauses.
- Specify liability limits and required insurance.
- Use a written contract even for small or friendly projects.
Pricing your work
Common models include hourly/day rates, fixed project fees, and success-based fees. Consider your experience, project uncertainty, client relationship, and how much non-billable time the project will require. Always account for taxes, insurance, and downtime.
Taxes and business form
In Hungary freelance engineers typically work as sole traders (egyéni vállalkozó) or through a Kft. Each form has different tax obligations, invoicing rules, and liability implications. Consult an accountant to choose the right structure for your income level and risk profile.
Managing risks
- Don't start work without a signed agreement and initial payment if applicable.
- Document scope changes and get client approval in writing.
- Keep professional liability insurance up to date.
- Set aside reserves for tax and quiet periods.
- Build a network of specialists you can collaborate with on larger projects.
