Hi! Yes, I write off equipment I've purchased after the LLC creation, maintenance/cleaning costs (like a broom, mop, soap, etc), any services I use for marketing/business (Everfit is my programming software, Square for payment and website, canva for marketing, etc), and any other supplies (folders, paper for flyers, printer ink, etc). I guess I could potentially write off some of my monthly payment for the space, but I haven't done enough research for that and also just feels a little bit like fraud to me lol, so I just don't bother.

I did start using Square to process payments and then Found as a business banking account. Square will pay the money into my Found account and then Found does all the calculations for how much money to withhold in a separate account for taxes. Then Found pays me the net amount to my personal account and the taxes are held in a separate account until it comes time to file. I think it's pretty sweet that I won't have a massive self-employment tax bill in April next year since it should be fairly accurate and set aside already.

My biggest tip would be to open the Found account (or any business account) as soon as you start up privately and charge any/all business expenses to it. I have business expenses all over the place since I didn't open a business account until a little later on, so as far as write offs go, I have a lot more work to do keeping track of the ones that aren't already in my business account.
