Boulder is home to about 105,000 people. The above-average cost of living means chess instructors charge more for services — but their software costs the same as everywhere else. High-cost cities make subscription fees sting more.
Chess Instructors in Colorado need a Business License. Requirements vary — contact your city or county business licensing office for current details.
Insurance: $500K-$1M general liability
Continuing Education: Check with state licensing board
Colorado has a 4.4% flat income tax. Flat 4.4% income tax. Complex local tax jurisdictions — over 70 home-rule cities with their own sales tax rates. Denver occupational privilege tax ($5.75/month for employees).
When evaluating software costs, factor in your effective tax rate. A $888/year software expense is partially deductible — but Nexa at $279 once is a one-time deduction that eliminates the recurring expense entirely.
Whether you call it invoicing, a app for jobs, or a invoicing system — most chess instructors in Boulder juggle Calendly, Acuity Scheduling, HoneyBook, FreshBooks and similar apps. That's $888/year in tool subscriptions. Over 5 years at today's prices, the total damage is $4,440.
Nexa means you stop renting software. Your CRM, invoicing, booking, jobs, time tracking, and financial tools — combined into one app. One click books a client. One click generates an invoice. No copying between apps. No integration hacks. No add-on costs. It's a buy once — stop overpaying the moment you switch. For chess instructors in Boulder weighing the switch, the 30-day money-back guarantee covers the migration window — you can run Nexa in parallel with your existing subscriptions, verify the workflow handles your real client load, and only cancel the monthly tools once you are confident the data and processes have settled in.
My lessons start at 3 when school lets out. First is a 1400-rated twelve-year-old prepping for the state scholastic championship, and we go through his last tournament game move by move on the board; he hung a knight in a won position, so we drill a blunder check before every move. At 4 I teach an 1800 adult working on the King's Indian Defense, going over the Mar del Plata lines and the kingside pawn storm, and I give him model games to play through. At 5 I have a six-year-old beginner, and we do king-and-queen versus king checkmate on the demo board until he can do it without stalemating. At 6 is the intensive, a tournament-prep client in the second of four lessons building her opening repertoire: we choose the Caro-Kann against 1.e4 and the Queen's Gambit Declined against 1.d4, and I build her a database file of the main lines with notes on the typical plans, not just move orders. For over-the-board events we also practice time management with a clock at 90 minutes plus a 30-second increment. At 8 I review results from yesterday's online tournament, run the students' games through an engine to find the turning points, and pick tactics puzzles for homework, because half of them didn't do last week's set and the lesson stalls when they don't. Then I confirm next week's times, send the tournament-prep package invoice, and remind the parents about the entry deadline.
That is the work Nexa is built around: the job, the client, the hours and the invoice live in one place, so the paperwork side of the day doesn't need a second shift.
Every one of those was bought once and earns its keep for years. Nexa is priced the same way: $279 once, and it keeps working whether business is busy or slow.

We build a chess instructor's guide the same way every time, and we'd rather you trust it than take it on faith. Nexa is our product, so the test we hold ourselves to is simple: a tool only "wins" a job here when it genuinely does that job better for a chess instructor — and where something free, open-source, or buy-once does it better, we say so and link you to it. Where Nexa falls short (payroll is the honest example), we name the alternative outright.
Found something out of date? Prices change and we don't catch every move the day it happens. This guide is published and maintained by the Nexa team; if a figure here is wrong, tell us and we'll fix it — getting it right matters more to us than the sale.
