Website Subscription charges

Hello, Any help is appreciated it!

I made a website for a company, and on this website, they can purchase company approved/selected items. It's basically like an online store but I manage it.

I paid for the domain & plan subscription with my business and later invoice the company for the website - I've recorded/paid the customer's invoice on QuickBooks desktop.

But how can I categorize the charge that I paid on my side?  Would it be an Expense or COGS? I would think COGS because the customer is getting an invoice for it. I don't think this is recorded the same as having my own company's website where people can see my services and business information, just your normal website., I also made my business website and paid for the domain, subscription, etc.

I get charged yearly for my company's and customer's website separately. what would be the best account below to put under?
