Non-Function Infrastructure Costs

This varies based on specific needs, but at a minimum, you'll need a domain to operate. An affordable option is an arbitrarily named .com domain, typically costing around USD $10-12 per year. For a Software-as-a-Service (SaaS) solution, the slightly more expensive .io top-level domain (TLD) is a popular choice, though it's not limited to that context

Now we need email. There are many options available. Some are "free," while others are nearly free. Most cost between $5-12 per month per user. This is affordable if you're the only employee for now. However, I recommend choosing a solution that allows you to scale up when you're ready.

I personally use Google Workspace (which costs between $5-12 per month per user), but if you don't trust Google, I've also heard great things about Proton Mail and Zoho Office solutions. Just do your research to ensure you're getting what you pay for. If data privacy is important to you, verify that the service guarantees not to resell your data.
