Your concept for “Agora Engine” as a company that helps businesses grow by providing services, while following strict payment policies like advance payments, is solid. However, there are a few key aspects to focus on:

1. Building Trust:

   Since you require advance payments, it’s important to build credibility with potential clients. Showcase testimonials, case studies, or a strong portfolio to prove the value of your services.

2. Transparent Policies:

   Clearly communicate your payment terms, refund policies, and service scope upfront to avoid confusion and build client confidence.

3. Competitive Pricing:

   While strict policies are fine, ensure your pricing justifies the value clients will receive. Highlight how your services lead to tangible business growth.

4. Customer Support:

   Offer excellent customer support to address any concerns, especially for first-time clients. This helps establish trust and ensures satisfaction.
