To update the amount you charge for your SEO services in the Merchant Center, you need to follow these steps:
1. Log in to the Hike platform and navigate to the Merchant Center.
2. Go to the "Pricing" section. Here, you can set up a platform-only and/or a platform-plus monthly support product priced in USD and GBP.
3. You can choose monthly, yearly, or both options. The minimum monthly and yearly prices are determined by the cost of Stripe and the minimum cost of Hike plus VAT.
4. Update your pricing as per your preference.
