It's very costly to run and maintain a website
It can lead to losses as websites can easily got hacked
It can lead to wastage of resources since websites are constantly down due to technical server errors.

Some of these can be mitigated. Employing adequate security measures and choosing reliable service providers go a long way, for example. I can't deny that managing a website can be expensive, that is basically a risk you take when you get started. Hopefully, over time, you get successful enough to make those costs worth it.

If you are using premium software like Shopify, you will have to spend a lot of money for website maintenance, if you use free platforms like woocommerce, your costs can be minimized and you can run the store for many years even when you are not making anmy profits.
