The IDEA requirements for event agencies are strict. The core requirements are listed below. 1) Sufficient business experience (at least 3 years). 2) At least 2 qualified staff members with certification. 3) Business liability insurance of at least 500,000 euros per claim. 4) Compliance with Dutch employment law, safety and GDPR. 5) Transparent pricing without hidden costs. 6) Written contracts with clients and suppliers. 7) A dispute scheme for disagreements. 8) Annual audit by an external auditor. Agencies must demonstrate compliance with these standards through documentation. IDEA also checks whether agencies keep client funds separate from their own accounts, as protection against bankruptcy. The requirements guarantee professional business operations.
