What gre prep tutors need from their software, from sources outside Calendly and outside Nexa:
Calendly covers the scheduling side of GRE tutoring well. Its simple booking links, buffer time between meetings and Zoom and Google Meet integration suit part-time tutors with uneven, seasonal, evening-and-weekend schedules. That matters most in the weeks before test dates. Its plan with payments also includes Stripe and PayPal payments, invoices and prepaid packages, which fits selling blocks of sessions. Clients don't need a seat. What Calendly's listed features don't cover is the business-tracking side. They include no expense or income tracking for the estimated tax payments a self-employed tutor has to plan for. They also have no way to record each student's test dates and retake count, or to keep test fees separate from tutoring fees.
Nexa covers more of that second half. It has invoices, recurring invoices and payment plans, with card payments through your own Stripe account. It also has expenses, profit and loss, and 1099 summaries for tracking income and setting tax money aside. Its CRM and client-linked notes can hold each student's test dates, attempt count and retake plan. It also has a public booking page with intake forms and reschedule and cancel links. Nexa lacks Google Calendar sync (calendar export is an .ics file) and has no app marketplace or integration library. It is software you own and run yourself, with no hosted support desk or vendor onboarding. Its automated emails and reminders send only while Nexa is open on one of your devices.
Over three years, Calendly at $12 a month is $144 a year, or $432. Nexa is $279 once (or 3 payments of $99) and runs on one device. Adding optional Cloud Sync at $4.99 a month brings three years to $458.64. If your calendar and video links are the center of your practice, stay with Calendly. If you mainly need invoicing, expense and tax tracking and student records, Nexa is worth a look, but you would give up Calendly's calendar and video integrations.
Our read for gre prep tutors: Stay with Calendly if Google Calendar and Zoom or Meet links drive your tutoring day; consider Nexa only if you mainly need invoicing and income tracking.

Calendly costs gre prep tutors $144/year at today's list price. Nexa is $279 once for invoicing, scheduling, CRM, time tracking and accounting in one suite — so after 23.3 months it has cost less than Calendly, and you own it after that. What it is not: hosted-for-you software with a support desk and a roadmap you can lobby. That is the trade, and the rest of this page is the detail behind it.
Nexa is $279 once, about $23 a month over its first year. Its Drain Guard reads your expenses (from a linked bank, an imported statement, or ones you type in), finds the charges that repeat, and adds them up by the month. Keep or Cut then walks you through them one at a time. Cancel $23 a month of charges you'd forgotten about and Nexa has paid for itself inside the first year, before you count the Calendly bill you'd stop paying.
It depends on what you find and what you cancel, so we don't promise a number. In our demo data, Drain Guard finds 5 subscriptions adding up to $110.13 a month. That is sample data, not a customer's.
The verdict for gre prep tutors: Stay with Calendly if the needs in our read above apply to you. If they don't, Nexa covers the core invoicing, scheduling and books for $279 once against $432 for Calendly over three years.
Scheduling, client records and invoicing are the pieces of that day. Some tools rent you each piece separately. A few — Nexa among them — bundle the lot and carry their own booking link, with no per-appointment cut. The sections below price both routes honestly.
None of that is a software problem you can buy your way out of in one click — it is why the tool you pick matters more than what it costs. Calendly solves some of it. So does Nexa. The difference is what you are left holding in three years.
Today's list price is $12/month — $144 a year, from Calendly's own pricing page. Every figure below is that price, multiplied. Nothing is projected.
Nexa: $279 once (or 3 × $99). Over the same three years, that is $153 less.
If Calendly raises its price, the three-year cost goes up; if it cuts it, the cost comes down. We don't guess which. Add-ons, extra seats and card-processing fees are not included, on either side.

✓ and ✗ for Calendly come from its own published feature list. — means the feature isn't in that list, which is not the same as Calendly lacking it: check with them. Three years is at today's price.
Straight from Calendly's own feature set. If one of these is the reason you pay them, that reason does not disappear because Nexa is cheaper.
Calendly is the better call if you need dead simple scheduling links specifically, or if your team is large enough that per-seat pricing still beats buying software outright.
Calendly's homepage says it is "Built for people whose work runs on meetings." It describes handling the tasks before, during and after meetings. Its pricing page lists solutions for individuals, small businesses and large companies, with pages for sales, marketing, customer success and recruiting teams. (calendly.com)

Software doesn't do the actual work — it automates the business around it. And that part is the same for every gre prep tutor: find the work, manage it, bill for it, get paid. Each step has a tool — and the right single tool runs the whole loop, so the handoffs are automatic and you get back to the actual work. Tap a step to see what gets automated.
An inquiry becomes a proposal becomes a signed engagement — the terms and the retainer set.
The work you're paid for — with the hours, tasks, and expenses tracked against the engagement instead of reconstructed at month-end.
The work becomes the invoice — the hours, the add-ons, the materials, the deposit credited — totaled and sent, instead of re-typed at 9pm.
Paid by card or link, the deposit credited, and what's overdue chased — without you doing it by hand.
You can stitch four separate subscriptions across these four steps, or run one tool that does the whole flow so a booking becomes a job becomes an invoice becomes a payment without re-typing. Either way the goal is the same: less time on the business of the business, more on the actual work. (Nexa is built to be the one — but the honest options for each step are above and below.)
This is the connection that makes the rest worth it. A gre prep tutor's job already holds the services, the hours, the add-ons, and the materials — so the invoice builds itself from the work instead of you re-typing it at 9pm. Toggle an add-on or nudge the hours and watch it recompute.
You didn't write this invoice — the job did.
Calendly plus whatever else you're paying for:

The median GRE Prep Tutor earns $42,000/year. At $144/year, Calendly is a recurring slice of that — paid again every year, whether the year was good or not. Owning the same jobs outright is $279 once, and the slice stops.
Nexa is $279 once. Invoicing, scheduling, CRM, time tracking, accounting — all connected, built for gre prep tutors. You own it like you own your Official ETS GRE guide and PowerPrep practice software.
An honest fit check — because the wrong tool is worse than no tool.
The honest fit: if you're a solo or small gre prep tutors business that owns its tools and is sick of renting software, Nexa replaces your whole stack for $279 once. If you're scaling into a large team with dedicated admin staff, a bigger platform may fit better — and we'd rather tell you that now than sell you the wrong thing.

Your clients are adults, so your day is the opposite of a school tutor's: sessions land early before work, at lunch, or at nine at night after the kids are down. The first is a software engineer whose quant is fine but whose verbal vocabulary is a wall — he's never had to know what 'laconic' means — so you drill high-frequency words in context, not flashcard rote. Midday is a returning student who hasn't touched math since undergrad and freezes on a data-interpretation chart that's really just careful reading and arithmetic; you rebuild her confidence one problem type at a time. The GRE's section-adaptive scoring means strategy matters, so you teach when to flag and move on rather than burning four minutes on one geometry problem. Between sessions you score an analytical-writing essay against the ETS rubric and give the kind of structural feedback that actually moves a 4.0 to a 5.0. Everything bends around application deadlines — a client realizes her program's cutoff is six weeks out and there's a mandatory wait between retakes, so you map the test date and a possible second attempt backward from that. A client cancels last minute because a work crisis ate his evening, and you reshuffle. You end the night confirming next week's odd-hour slots, because for working adults the schedule is the hardest part of all.

The tools of the trade — each a one-time buy that earns its keep for years.
You paid for these once because good tools last. That's the bar your software should clear too — priced like a tool you own, $279 once, not a subscription that costs more than your kit every year.
We build a gre prep tutor'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 gre prep tutor — 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.
For solo gre prep tutors and small teams, yes. invoicing, scheduling, CRM, time tracking, task management, and full accounting — all for $279 once. Calendly may be better if you have a large team (10+) or need enterprise-specific features.
Calendly has features like Dead simple scheduling links and Clean UI/UX that some businesses rely on. For most solo gre prep tutors, these aren't dealbreakers.
At $12/month, Nexa pays for itself in 23.3 months. After that: $144 saved every year.
Yes. Nexa is $279 as a one-time payment, or 3 payments of $99 ($297 total). Either way it's a one-time purchase — no subscription, no recurring fees ever.
