If you're in the US, you may want to consider joining the American Bookseller Association or a regional bookseller chapter. It isn't absolutely necessary and there can be drawbacks, but there are definitely benefits. Membership allows you to take classes or go to conferences specifically about opening/running a bookstore. They can help connect you with reps from publishing houses. They host conferences that have vendors and authors and sessions and networking that are super helpful...there is also something called the Bookstore Training Group that people recommend. I know some who have actually gone to the in-person "bootcamp" and some who have done the books on their own, but it comes recommended by everyone I know who has done it...if none of those options appeal, try reaching out to bookstores for general advice. I have been loosely planning on opening a bookstore in the future, and when I travel, I email local indies ahead of time and ask if I can set up a meeting with an owner or manager. I always offer to pay for their time or take them to a meal afterwards. Sometimes they offer help but don't take payment. Other times we end up having a nice lunch somewhere. Some people say no. But it doesn't hurt to ask and booksellers in general have been super nice and accommodating and want to see others succeed!

Can you specify what you mean? “Outside of inventory and furnishings” ... like a cash register? Office supplies? Signs? That kind of stuff?

Either way, my advice is to use youtube university to learn more about small business needs and visit as many bookshops and independent businesses you can and take notes on what you see.

Might be pretty self explanatory but a POS system, some way to keep an inventory catalogue, maybe getting a website set up for online sales and local pick up, insurance, a business license. Not to mention branding and packaging materials (bags, gift boxes, shipping packaging and labels). Probs start with finding an accountant and a bank for a loan to make everything happen.
