I’m set up as sole proprietor. (Mainly sell seasonally at renfair)
Get set up with state sales tax. You have option of filing quarterly or yearly (if under a certain amount, most small craft businesses, not an issue). Plus it’s really useful to have for wholesale purchase. Don’t mess around with not filing this correctly or on time. Any issues or questions, the folks at your local field office are super helpful and way better than dealing with the 800 number.
Dba, nowadays you need if open business bank account. Used to vary, but last number of years seems consistent. It’s handy to have things separate from personal money, especially for business expenses, clearer money trail for taxes, etc rather than commingling with personal money. You have renew DBAs with the county every 10 years.
Credit card processing, I use Square. There are others. Do some reading. Some have crappier reputations on resolving conflicts and chargebacks or the way they tie up money. I haven’t had any real issues with square. We use one of our slightly older cell phones after we upgrade (wifi signal) for the app, not our actual personal ones in case dropped/stolen.
HIGHLY recommend mobile hotspot if doing craft shows to avoid headaches with spotty recpeption. Pay attention to your likely selling areas, what’s best coverage (for example, at renfair, has to be sprint friendly since only nearby tower in rural area after a tornado ate the AT&T tower a few years ago and it was never replaced). You CAN process offline transactions that wait until signal, but if it’s bad later, you’re stuck unless you collected more info. Also battery pack. Sucks if your money stuff (device with app, hotspot, chip reader) needs a drink and goes down because you don’t have easy electricity. Just sayin.
Chip readers…you definitely want chip reader. Take a chipped card as a swipe and any issues like chargeback or declined later (if offline transaction) you’re up a creek. Liability on you. Non-chip, onus still on credit card company. Chipped it’s on you to take it as a chip. IMPORTANT, chipped cards, the reader HAS to have internet access to verify. Thus WiFi/internet important unless you want to gamble on later verification. Or can take a chip as a swipe (we do very occasionally on smaller amounts if our setup is having issues taking too long to troubleshoot while we’re busy and it’s a small enough amount I’m willing to risk the loss if it’s an issue.) All in all, very few issues, but may depend on venue.
I use TurboTax and file Schedule C. Keep track of ANYTHING business related. Dedicated home office or work area, tools, materials, costs of selling and doing business, displays, costumes, mileage, all of it.
Some venues require liability insurance, even if it’s not something you’re worried about at home/work location.
There’s a difference between liability for your sold item or someone hurt where you sell vs say theft or loss at your home. That, personal business loss, you need to talk to your insurance agent for something like a rider on your homeowners policy. If you need liability insurance for actual selling at venue, ACT Insurance is good. It’s specifically for artist and craft show liability insurance. You can get an annual policy (includes product liability), or 1-90 days (general liability, not product). For the eight-week renfair I do, it’s $89. A lot of folks are using this nowadays and seems to have a good rep. https://www.actinsurance.com/
Displays for craft shows, there’s some good groups dedicated to this on fb you might check out.
