Karate Instructors face unique challenges: Belt testing happens on a cycle and I'm chasing who's eligible, who paid the test fee, and who's ready on kata. Kids' classes are the bulk of my income, which means parents, waivers, and tuition autopay I manage by hand. Tournaments require travel, registration, and permission slips I coordinate for a whole team at once. Retention drops after kids earn a few belts and parents decide they've 'done karate' and quit. On top of all that, Calendly charges $12/month ($144/year) — money that comes directly from your revenue. The median Karate Instructor earns $40,000/year. Software at $144/year is a meaningful percentage of that income, every year, forever. And you do not own anything.
Your Gi (karate-gi) and belt set is yours. You bought it once. Nexa works the same way — $279 once for invoicing, scheduling, CRM, time tracking, and full accounting. All connected. All offline-capable. You own it like you own your tools.

I open the dojo, bow in, and line up the day. Afternoons and evenings are my bread and butter — kids' classes, where the real business lives. The little ones need structure and energy, so I run them through stances, basic blocks, and a kata, handing out the discipline and the fun in equal measure while parents watch from the chairs. I'm tracking which kids are close to testing for the next belt, who's mastered their kata, and who needs another cycle. Between classes a parent asks about the upcoming belt test and whether her son's ready and what the fee is, and I'm answering from memory because my eligibility list is a marked-up roster. We've got a tournament coming, so I'm collecting registration money and permission slips from a dozen families and trying to coordinate who's competing in what division. The adult evening class is smaller — more sparring, more advanced kata — and I gear them up for controlled sparring, watching for safety. Admin is relentless behind the scenes: tuition that's supposed to autopay but a few cards expired, test fees, the new student whose waiver I never got signed. I notice a couple of green belts haven't been back — that classic drop-off where the family feels they've 'done karate' once the kid has a colored belt. I close the dojo knowing I should call those parents before they're gone for good.
