Is monthly flat fee really better than per transaction for low volume stores? I keep seeing conflicting advice.

I've been reading through a bunch of threads here and on other forums about pricing models, and I feel like everyone just picks a side and runs with it. For my small side hustle (I sell handmade guitar straps at local craft fairs maybe 8 times a year, pulling in around $400 per event), I keep seeing people say go with a flat monthly fee to save money. But when I actually crunched the numbers on a Square reader versus a traditional merchant account with a $25 monthly minimum, the flat fee would eat up like 6% of my sales during slow months. Meanwhile the per transaction guys say I'm overthinking it and just paying an extra 50 cents per swipe matters more to me than a big monthly bill. I had a guy at a vendor meetup in Portland last fall swear his monthly plan saved him $300 a year, but he was doing $12k a month in sales at a food cart. So what's the real cutoff point where one option clearly beats the other? Has anyone actually done the math on their own numbers and switched?

Flat fee versus per transaction is like trying to pick the lesser of two weasels. I spent a whole weekend with a calculator and a cold beer trying to figure out the same thing for my own small gig. The $2,000 a month number feels about right to me from what I've seen. Below that and the flat fee just feels like a tax on being small where you're paying for services you're not really using. Above that and the percentage adds up faster than your sales do. I've made dumber mistakes with my money before so I'm not claiming to be an expert here but that's where my math landed.

Right on, I totally get where you're coming from! I did the exact same math last year for my weekend hobby selling vintage vinyl at a local flea market, and it drove me nuts. I was doing about $600 a month in the summer and maybe $150 in the dead winter, and the flat fee would have been a killer on those slow months, like you said, it would have eaten up over 10% of my sales easy. I actually tried a per transaction setup for a season and the 2.7% plus 10 cents felt way more manageable when I had a bad day, I could just skip taking cards and not lose a monthly minimum. The cutoff point for me seems to be if you're doing less than $2,000 a month consistently, skipping the flat fee wins every time.

Dig into that $2,000 number a bit more for me. Is that a hard cutoff for you or just a rough ballpark based on your own sales swings? I ask because I'm always wondering if the timing of those slow months matters more than the average. Like, if you know December is dead and January picks back up, could you just eat the flat fee on the lean month and still come out ahead across the whole year?
