You break even in 4.2 months. After that, every dollar your competitors spend on subscriptions is money you keep. At median dietitian earnings, $792/year in software represents 33 hours of work — time spent earning money just to hand it to SaaS companies for tools you never own.

FAQ

Is Nexa actually built for dietitians?

Yes. The invoicing module is designed for dietitians who need to professional invoicing with payment tracking, reminders, and automated follow-ups. Plus you get scheduling, CRM, time tracking, and full accounting — tools most dietitians end up needing anyway. $279 total for everything.

$279 seems expensive upfront. Is it worth it?

$279 spread over 3 years is $7.75/month. You're currently paying $66/month for Acuity Scheduling + FreshBooks — that's $2,657 over 3 years. Nexa saves you $2,378 over that period. The math isn't close.

What if I don't like it?

30-day money-back guarantee. Full refund, no questions. If Nexa doesn't save you $500 in year one, you get every penny back.

Can I switch from Acuity Scheduling?

Yes. Export your data as CSV, import into Nexa. Most dietitians are fully switched in 1-2 days. Run both in parallel until you're confident — zero risk.

How does Nexa compare to what other dietitians spend?

The median dietitian earns $50,000/year. Software subscriptions at $792/year represent 1.6% of that income — every single year. Nexa at $279 once is 0.56% of annual income, paid one time. The difference compounds every year you operate.

Why One App Beats Three Subscriptions

Most dietitians cobble together 3-5 separate apps — one for scheduling, one for invoicing, one for bookkeeping, maybe another for client management. Each one charges monthly. None of them talk to each other. So you end up copying client info between apps, manually reconciling invoices with your books, and losing track of details that fall through the cracks.

For the way a dietitian actually works, Nexa keeps one record instead of five logins. You finish the job and the invoice generates from that same record — no retyping into a second app between calls. The hours feed your P&L automatically, a client who books online lands in your CRM with their history, and the Nutrition analysis software you bought once is finally matched by software you buy once. The "insurance vs. private pay billing complexity" problem goes away. No Zapier, no CSV exports. $279 once — or $99 today and two more — and the whole integrated system is yours, break-even in 4.2 months. 30-day money-back guarantee. And because there's nothing to renew, a dietitian who switches keeps paying $0/month while competitors keep paying $66/month — that gap compounds every year you own it.
