FreshBooks vs Nexa The Real Comparison for Six Sigma Consultants
FreshBooks
$43/mo ($516/yr)
VS
Nexa
$279 once — own forever
or 3 payments of $99
Break even: 6.5 months at FreshBooks's current price.
Bottom Line
FreshBooks costs six sigma consultants $516/year at today's list price. Nexa is $279 once for invoicing, scheduling, CRM, time tracking and accounting in one suite — so after 6.5 months it has cost less than FreshBooks, 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.
Can it pay for itself?
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 FreshBooks 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 six sigma consultants: FreshBooks is solid software, but at $43/month it costs $1,548 over 3 years. Nexa does most of what FreshBooks does for $279 once. For solo six sigma consultants and small teams, Nexa is the better deal.
Choose Nexa if:
You're done paying monthly forever
You're a solo operator or small team (1-5)
You need connect crm, scheduler and invoicing in one tool
You're tired of price increases
You want to own your tools like you own your equipment
Choose FreshBooks if:
You have a large team (10+) needing enterprise features
You're deeply invested in FreshBooks's specific workflow
You need a feature Nexa doesn't have yet
Sound Familiar?
A Six Sigma consultant fights variation with data, and the day swings between the floor and the spreadsheet. Defining a project means pinning down a charter with the client: the problem in measurable terms, the baseline defect rate, the goal, and a real dollar figure to justify the work. Then comes measure, which often surprises the client, because before trusting any data the consultant runs a gauge R&R and frequently finds the measurement system is so noisy that operators measuring the same part get different answers, meaning the first fix is the gauge, not the process. Analyze is heads-down time in Minitab, hunting for the vital few causes with Pareto charts, hypothesis tests, and capability studies that separate signal from noise. Improve is back on the floor, piloting a change and confirming with data that it actually moved the metric. Much of the role is coaching: the consultant is usually mentoring the client's own Green and Black Belts, resisting the urge to just do the analysis and instead teaching them to read a control chart and defend a conclusion. The quiet killer is the control phase, where the project closes, attention drifts, and without control charts and response plans the defect rate creeps back. So the consultant builds the monitoring in and returns to verify the process is still in control.
Trusting the data when a gauge R&R shows the measurement system itself is most of the variation
Keeping a DMAIC project moving through its phase gates when the client's belt loses momentum
Coaching client Green Belts through their projects without doing the analysis for them
Holding the gains in the control phase after the project officially closes
Client records, scheduling, invoicing and time tracking 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. FreshBooks solves some of it. So does Nexa. The difference is what you are left holding in three years.
What FreshBooks Actually Costs Six Sigma Consultants
Today's list price is $43/month — $516 a year, from FreshBooks's own pricing page. Every figure below is that price, multiplied. Nothing is projected.
Three years at today's price
Year 1$516
Year 2$516
Year 3$516
Three years of FreshBooks$1,548
Nexa: $279 once (or 3 × $99). Over the same three years, that is $1,269 less.
If FreshBooks 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.

What "$279 Once" Does And Doesn't Buy
It buys the software, not a service contract. You install Nexa and it runs on your machine. There is no seat count, and nothing stops working if you stop paying, because there is nothing to stop paying.
FreshBooks's monthly fee is not only rent. It pays for their hosting, their support desk, and their engineers shipping changes every week. If those matter to how you work, that is a real thing you would be giving up.
Cross-device sync is the one optional extra — $4.99/month if you want your data mirrored between machines. Skip it and Nexa still works; you just sync manually.
The honest risk of buying once: you are betting on us still being here to improve it. The honest risk of renting: the price is theirs to raise, and the graveyard section below is a record of tools that did exactly that.
What FreshBooks Does Better
Straight from FreshBooks's own feature set. If one of these is the reason you pay them, that reason does not disappear because Nexa is cheaper.
Very user-friendly for non-accountants
Built-in time tracking
Excellent mobile app
Professional invoice templates
Client portal
A smaller bill up front: plans start at $23/month, against $279 paid once for Nexa.
FreshBooks is the better call if you need very user-friendly for non-accountants specifically, or if your team is large enough that per-seat pricing still beats buying software outright.
What FreshBooks Is Built For
FreshBooks says it is "perfect for everyone from self-employed professionals to growing business owners." It lists four audiences: freelancers, solopreneurs, businesses with employees, and businesses with contractors. (freshbooks.com)
The Lite plan covers 5 billable clients, Plus covers 50, and Premium and Select cover unlimited clients. The client count includes archived clients, and deleting a client frees a slot. (freshbooks.com)
Plus adds proposals, retainers, financial reports, receipt scanning, accountant access, double-entry reports and bank reconciliation. Premium adds custom email templates, automated client emails, project profitability and accounts payable. (freshbooks.com)
It offers a 30-day free trial with no credit card required, and a 30-day money-back guarantee after purchase. Free phone and email support is included during the trial. (freshbooks.com)
The Select plan includes 2 team seats, Advanced Payments, Easy Switch migration, onboarding, a dedicated Account Manager and dedicated phone support. Lower card fees and capped ACH fees apply on this plan. (freshbooks.com)
The FreshBooks AppStore advertises 100+ apps. The core tools are invoicing, billing and payments, expenses and payroll. Time tracking, bank reconciliation, client retainers and mobile apps are also listed. (freshbooks.com)
The site says its support staff are based across North America and that it "never transfers you to other departments." It also says the support team has won 11 Stevie Awards. (freshbooks.com)
What people outside FreshBooks and outside Nexa say:
NerdWallet rates FreshBooks 4.7/5 and calls it "a good fit for freelancers and service-based businesses with straightforward accounting needs." It calls the invoicing "exceptionally user friendly" and says all plans include time tracking. It also praises the project management tools included in all plans as a "solid value-add for freelancers." (nerdwallet.com)
NerdWallet's criticisms: the Lite plan lacks bank reconciliation, accountant access and double-entry reports. Reporting is limited, and standard reports can't be filtered by client. Users report payment processing delays, especially with Stripe, and some sync issues. Support is mainly by phone, with online help going through a chatbot. The review says FreshBooks trades functionality for simplicity, so businesses with complex accounting needs may want another product. (nerdwallet.com)

Where business tools fit — for a six sigma consultant
Software doesn't do the actual work — it automates the business around it. And that part is the same for every six sigma consultant: 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.

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.)
Watch a job become an invoice
This is the connection that makes the rest worth it. A six sigma consultant'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.

What This Means for Six Sigma Consultants
The median Six Sigma Consultant earns $55,000/year. At $516/year, FreshBooks 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 six sigma consultants. You own it like you own your Minitab or statistical analysis software.
Is Nexa actually right for a six sigma consultant?
An honest fit check — because the wrong tool is worse than no tool.
Right for you if
You run solo or a small team — like the 15,000 six sigma consultants in the US who do, and you wear every hat.
You're tired of paying every month for a monthly subscription stack and a pile of apps that don't talk to each other.
You want invoicing, scheduling, and client tracking in one place — not scattered across five apps.
You'd rather own your software once, the way you own your Minitab or statistical analysis software.
Look elsewhere if
You have a large team that needs enterprise seats, granular roles, and dedicated admin staff — Nexa is built for solo and small operators (1–5), and a bigger platform will serve you better.
You need full payroll for a large team or deep, SKU-level inventory — that's not what Nexa is for.
You're genuinely happy paying monthly and don't mind stitching tools together. No tool fixes a workflow you already like.
The honest fit: if you're a solo or small six sigma consultants 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.
Client records, scheduling, invoicing and time tracking 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.

A day in the life of a six sigma consultant
A Six Sigma consultant fights variation with data, and the day swings between the floor and the spreadsheet.

So the consultant builds the monitoring in and returns to verify the process is still in control.

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.
Where Nexa wins for a six sigma consultant — and where it doesn't
The honest version. Nexa was built to beat the rented stack on the jobs that matter most to a six sigma consultant — here's where it wins, where the integration wins it anyway, and the things it genuinely doesn't do, with who to use instead. (No tool is best at everything; a guide that pretends otherwise is just an ad.)

How To Read This Page
We make Nexa. It is one of the two options compared here, so read this with that in mind. We have tried to make FreshBooks's case the way we would want ours made — their strengths above are their own published feature list, not our summary of it.
The prices are FreshBooks's published list prices, checked on the date shown in the sources below. Plans change; check theirs before you decide.
No customer quotes appear on this page because we do not have any from six sigma consultants we can verify. For user testimony, read the independent reviews — FreshBooks on G2 and on Capterra — where the reviewers are not selling you anything.
Check the price yourself:FreshBooks's own pricing page is the source for every figure above, read on the date shown in the sources section below.
We are not neutral about subscriptions, and that is the argument, not a hidden assumption: software you pay for once is cheaper over three years than software you rent, unless you need something only the rented one does.
How we put this guide together
We build a six sigma consultant'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 six sigma consultant — 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.

Income contextThe $55,000 median we cite for the typical six sigma consultant is occupational median annual pay from the U.S. Bureau of Labor Statistics (Occupational Employment & Wage Statistics), compiled April 2026. We use it only to show software spend as a share of real income — your own numbers will differ.
Three-year mathMulti-year totals are today's list price multiplied by the number of years. No price rise is projected, so the figure can be checked against the vendor's own pricing page; if they raise it, the real cost is higher.

FAQ
Is Nexa really a FreshBooks replacement?
For solo six sigma consultants and small teams, yes. invoicing, scheduling, CRM, time tracking, task management, and full accounting — all for $279 once. FreshBooks may be better if you have a large team (10+) or need enterprise-specific features.
What does FreshBooks do that Nexa doesn't?
FreshBooks has features like Very user-friendly for non-accountants and Built-in time tracking that some businesses rely on. For most solo six sigma consultants, these aren't dealbreakers.
How fast does Nexa pay for itself?
At $43/month, Nexa pays for itself in 6.5 months. After that: $516 saved every year.
Can I pay in installments?
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.
