Boulder is home to about 105,000 people. The above-average cost of living means garage sale flippers charge more for services — but their software costs the same as everywhere else. High-cost cities make subscription fees sting more.
Garage Sale Flippers 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 $684/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 solution for jobs, or a invoicing system — most garage sale flippers in Boulder string together QuickBooks, Wave, FreshBooks, Square plus other subscriptions. That's $684/year in tool subscriptions. Across five years at today's prices, you're looking at $3,420.
Nexa gives you the ability to exit the subscription trap. Your CRM, invoicing, booking, jobs, time tracking, and financial tools — in a single solution. A single action books a client. A single action generates an invoice. No copying between apps. No third-party glue. No integration tax. It's a lifetime license — save money from the first day. For garage sale flippers 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.
The alarm goes off at 5:40 on a Saturday because the good estate sales open at seven and the line forms before that. You map four addresses from the Craigslist listings, hit the cash machine for small bills, and load the empty van. At the first sale you're scanning tables fast: a box of vintage Pyrex, a cordless drill, a tub of designer handbags you'll have to authenticate later. You lowball politely, haul it to the van, and move on before the dealers clean out the next house. By noon the van is full and the back of your SUV smells like other people's basements. Afternoon is the unglamorous half: wiping down, testing the drill battery, photographing each piece in good light, writing honest listings, and looking up sold comps so you don't underprice the Pyrex or overprice the purse. You answer a dozen lowball messages, schedule two porch pickups, and pack three items that sold overnight. Somewhere in there you log what you paid for each thing, because come spring the only way to prove your real profit is the cost basis you wrote down today. You close the laptop knowing tomorrow you do it again.
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 garage sale flipper'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 garage sale flipper — 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.
