What iso consultants need from their software, from sources outside HoneyBook and outside Nexa:
HoneyBook covers the client-facing side of an ISO consulting practice well. It has unlimited clients and projects, proposals and contracts, a client portal, invoices and payments, and Google Calendar, Zoom and Gmail integrations. That is enough to scope, sign and bill each engagement. Nothing on its feature list is built for what this trade turns on: a per-client record of when each consulting engagement ended, so a consultant who also audits for a certification body can show the two-year gap. The same goes for audit-day estimates tied to client headcount, and for a calendar of standard revision and transition dates, such as the expected ISO 9001:2026 publication and the transition that follows. You would have to build those yourself from project notes and calendar entries.
Nexa covers similar ground. It has quotes and proposals that convert to invoices, a client pay portal where clients pay by card through your own Stripe account and sign estimates, and a CRM with tags, notes and a pipeline board. It also has missions with sub-steps and templates, and time tracking. You could keep consulting and auditing work apart with tags and notes, and log engagement dates in them. Its calendar export is an .ics file, with no Google Calendar sync. Nexa also has no QuickBooks or Xero sync, and there is no hosted support desk or vendor onboarding. If you use automated emails or reminders, they send only while Nexa is open on one of your devices.
Over three years HoneyBook at $36 a month is $432 a year, or $1,296. Nexa is $279 once, or $458.64 with optional Cloud Sync at $4.99 a month for all 36 months. The price gap does not settle this, because neither tool tracks the two-year impartiality window or the revision deadlines for you. If you stay on HoneyBook, or move to Nexa, keep a separate engagement register with end dates and a two-year flag, and a deadline calendar for each client. A tool with custom date fields and due-date reminders, built for engagement or practice records, would fit the core need better than either.
Our read for iso consultants: Neither HoneyBook nor Nexa has a built-in record of consulting end dates for the two-year impartiality check, so use an engagement-register tool with custom date fields and reminders.

HoneyBook costs iso consultants $432/year at today's list price. Nexa is $279 once for invoicing, scheduling, CRM, time tracking and accounting in one suite — so after 7.8 months it has cost less than HoneyBook, 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 HoneyBook 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 iso consultants: Neither HoneyBook nor Nexa is the main system for this work; start with software built for it. Nexa only makes sense beside it, at $279 once against $1,296 for HoneyBook over three years.
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. HoneyBook solves some of it. So does Nexa. The difference is what you are left holding in three years.
Today's list price is $36/month — $432 a year, from HoneyBook'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 $1,017 less.
If HoneyBook 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 HoneyBook come from its own published feature list. — means the feature isn't in that list, which is not the same as HoneyBook lacking it: check with them. Three years is at today's price.
Straight from HoneyBook's own feature set. If one of these is the reason you pay them, that reason does not disappear because Nexa is cheaper.
HoneyBook is the better call if you need beautiful proposals and contracts specifically, or if your team is large enough that per-seat pricing still beats buying software outright.
HoneyBook describes itself as built for anyone with clients, aimed at small businesses that work with clients. Its categories are event services, marketing, design and creative, professional services, personal services, and home and real estate. (honeybook.com)

Software doesn't do the actual work — it automates the business around it. And that part is the same for every iso 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.
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.)
HoneyBook plus whatever else you're paying for:

The median ISO Consultant earns $55,000/year. At $432/year, HoneyBook 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 iso consultants. You own it like you own your ISO 9001 / 14001 / 27001 standard documents.
An honest fit check — because the wrong tool is worse than no tool.
The honest fit: if you're a solo or small iso 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.

An ISO consultant takes a company from nothing to certified, and the day's shape depends on where each client sits on that road. Early-stage clients need a documented system built from scratch: writing the quality policy, mapping the processes the business actually runs, and creating the procedures, forms, and records the standard requires, all in language the staff will use rather than file away. Mid-stage work is implementation and internal auditing, walking the floor to see whether the new procedures are being followed, then training the client's own people to audit themselves so the certification doesn't collapse the moment the consultant stops coming. Pre-audit days are intense: a gap assessment against the standard clause by clause, a mock management review, and a punch list of everything the registrar will catch. After a stage 1 audit, the work becomes closing nonconformities, root-causing each finding with the responsible manager and proving the fix before stage 2. Across all of it, the consultant is running several clients at different milestones, one drafting its first document control procedure, another a week from its surveillance audit, and the constant risk is letting one client's policy template or audit schedule drift into another's binder. Evenings go to readiness tracking and reminding clients which deadlines are closing in.

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 an iso 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 an iso 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.
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 iso consultants and small teams, yes. invoicing, scheduling, CRM, time tracking, task management, and full accounting — all for $279 once. HoneyBook may be better if you have a large team (10+) or need enterprise-specific features.
HoneyBook has features like Beautiful proposals and contracts and Client portal that some businesses rely on. For most solo iso consultants, these aren't dealbreakers.
At $36/month, Nexa pays for itself in 7.8 months. After that: $432 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.
