Consider their experience in your industry, client testimonials, and any relevant certifications. A reputable firm is more likely to provide high-quality and reliable auditing services.
  • Cost vs. Quality: Strike a balance between cost and quality. While cost-effectiveness is important, prioritize auditing firms that offer value for money. Assess the comprehensive package, considering not only the price but also the expertise, technology, and additional services provided.

SLAs provide a structured framework for the outsourcing relationship, setting expectations and ensuring accountability.

Define reporting formats, frequency, and the individuals responsible for communication on both sides.
