To ensure your IT provider is doing a good job, here are a few things you should do:

1. Clearly define your expectations: Clearly communicate your needs and expectations to your IT provider. Be specific about your requirements, timelines, and desired outcomes.

2. Regularly review their performance: Periodically assess your IT provider's performance against the agreed-upon service level agreements (SLAs) and Key Performance Indicators (KPIs).

3. Seek customer feedback: Encourage your employees or end-users to provide feedback about their experience with the IT provider.

4. Stay informed: Keep yourself updated on the latest technology trends and industry standards.

5. Maintain open communication: Foster a culture of open communication with your IT provider. Regularly engage in discussions, ask questions, and provide constructive feedback.

Remember, regular communication, performance evaluation, and aligning goals will help establish a healthy and productive relationship.
