Last November I was onboarding a new client, a VP of product who'd been referred by someone I'd worked with two years ago. Good energy on the chemistry call. She signed the proposal the same day. And then I spent the next forty minutes trying to figure out where I'd put my intake questionnaire.
It wasn't in Google Docs. It wasn't in the coaching platform I'd been paying $29/month for and barely opening. It was in an email draft I'd started customizing six months earlier and never finished. I eventually found it, sent it over, and she was gracious about the delay. But I sat there afterward with my green tea going cold, thinking: I have been doing this for nine years and my onboarding process is held together with tape.
That was the week I finally sat down and sorted this out for real. Not by finding the perfect platform. By getting honest about what I actually need and what I was paying for out of guilt.
Here's what I've figured out, and what I'd tell you if we were having this conversation in person.
The five things, and you only need three
Every coaching platform, every single one, does some combination of the same five things: scheduling, intake forms, payment processing, session notes, and contracts. The marketing pages make it sound like each tool has reinvented the wheel. They haven't. It's the same wheel with different paint.
Here's what took me too long to learn: I only need three of those five to be handled well. Scheduling, payment, and notes. That's it. Intake I handle with a Notion form I send manually (more on that later). Contracts I do through a simple PDF I built once and update maybe once a year. I don't need software for that. I need a filing system.
The moment I stopped trying to find one tool that did everything and started asking "what do I actually touch every week," the whole decision got simpler.
You might need different things than I do. If you're sending proposals to corporate clients with procurement departments, you need something more buttoned-up on the contract side. If you're running group programs, you need scheduling that handles cohorts. But if you're a solo coach seeing 12 to 15 people, most of the features on these platforms are built for a practice that isn't yours.
Paperbell: clean, simple, and built for a specific coach
Paperbell is the one people recommend first, and I understand why. It's genuinely easy to set up. The interface is clean. You can have a coaching package page live in about an hour, and it handles scheduling, payment, and basic intake in one flow.
The thing Paperbell is genuinely good at: the client purchase experience. If you sell coaching packages directly to individuals (not through organizations), the flow from "interested" to "paid and scheduled" is the smoothest I've seen. It feels professional without feeling corporate.
What they oversell: the idea that it's a complete practice management system. It's not. Session notes are an afterthought. There's no real client progress tracking. If you want to look back at six months of work with someone and see the arc, Paperbell won't help you.
Who it's actually for: coaches in their first two or three years who are selling packages directly to individuals and want to stop cobbling together Calendly plus Stripe plus Google Forms. If that's you, Paperbell is probably worth the money. If you've been at this for a while and your needs are more specific, you'll outgrow it fast.
I used Paperbell for about four months in 2023. It was fine. I just didn't need what it was best at, because most of my clients come through referrals and the sale happens in conversation, not through a purchase page.
Simply.coach: the most ambitious, for better and worse
Simply.coach is trying to be the everything platform, and to their credit, they're closer than anyone else. Goal tracking, session notes, client dashboards, even some organizational coaching features if you're working with teams.
The thing Simply.coach is genuinely good at: structure for the coaching engagement itself. If you like having a visible arc for each client, goals they can update between sessions, action items you both can see, this is the best implementation I've found. It treats coaching as an ongoing relationship, not just a series of calendar events.
What they oversell: the idea that clients will actually log in and use their side of the platform. In my experience, I set up the client portal with a wonderful onboarding flow and then about three out of ten clients ever looked at it again. Most people don't want another login. They want to do their work in the session and maybe get a follow-up email.
Who it's actually for: coaches who work within organizations and need to show progress reports to sponsors or HR. Also coaches whose methodology is very structured, lots of assessments, goal tracking, milestone check-ins. If your coaching is more emergent (which mine tends to be), the structure can feel like overhead.
On the AI front: Simply.coach has started integrating AI features, and I'll say this, they're the one platform that seems to be thinking about it seriously rather than just bolting on a chatbot and calling it innovation. Their AI-assisted session notes are moving in the right direction. Not there yet. The summaries still miss nuance in ways that matter (I ran a few through Margaret for comparison and Margaret's were consistently better because I've spent months teaching her how I think about client work). But Simply.coach is at least asking the right questions about where AI belongs in a coaching platform. Most of the others are either ignoring it or doing it badly.
CoachAccountable: ugly, powerful, and oddly beloved
I need to be honest about something. CoachAccountable looks like it was designed in 2011 and never updated visually. The interface is dated. The learning curve is real. The first time I logged in, I closed the tab after ten minutes.
But here's the thing. I keep meeting experienced coaches, people who've been doing this work for a decade or more, who use CoachAccountable and won't switch. When I ask why, the answer is always some version of: because nothing else tracks client progress this well.
The thing CoachAccountable is genuinely good at: the underlying logic for how it thinks about coaching engagements. Metrics, worksheets, action items, session history, all connected in a way that lets you see the full picture of a client relationship over time. The accountability features (automated check-ins between sessions, progress tracking) are more sophisticated than anything else on the market.
What they oversell: honestly, they don't oversell much. Their marketing is almost as dated as their interface. Which might be why coaches trust it.
Who it's actually for: established coaches who have a clear methodology, care about tracking outcomes, and are willing to invest a few hours in setup. Not for someone who wants to be up and running in an afternoon. Very much for someone who wants a system that rewards the investment over months and years.
I didn't stick with CoachAccountable, but that's a "me" thing, not a quality judgment. My coaching style is less structured than what the platform assumes. I don't assign homework. I don't track metrics between sessions. The coaches I know who love it tend to have a more systematic approach, and the platform serves that beautifully.
HoneyBook: not built for you, but maybe useful anyway
HoneyBook wasn't designed for coaches. It was built for freelancers, photographers, event planners, people who send proposals and contracts and invoices as part of a project-based workflow. But I know at least four coaches who use it, and a couple of them are quite happy.
The thing HoneyBook is genuinely good at: the proposal-to-contract-to-payment pipeline. If you do a lot of custom proposals (especially for corporate clients or higher-ticket engagements), the flow is polished. Clients can review, sign, and pay in one sequence. It feels professional.
What they oversell (for coaches specifically): calling it "client management." It manages projects and transactions. It doesn't know what a coaching session is. There's no concept of recurring sessions, session notes tied to a client record, or any coaching-specific logic. You're fitting your practice into someone else's container.
Who it's actually for: coaches who primarily need a good invoicing and contract system, especially those working with organizations where the buying process is more formal. If your main pain point is "chasing payments feels terrible and I hate sending invoices," HoneyBook solves that well. If your pain point is "I need a better system for managing the actual coaching work," look elsewhere.
The Notion option (what I actually use, and I'm not alone)
Here's my confession. After trying dedicated coaching platforms, after giving three of them an honest shot of at least two months each, I ended up on Notion. Combined with Calendly for scheduling and Stripe for payments. Three tools. None of them built for coaching. All of them doing exactly what I need.
I know this is slightly embarrassing given that I just reviewed four purpose-built coaching platforms. But I keep having conversations with experienced coaches who've landed in the same place, and I think there's a reason.
Notion lets me build exactly the system I need and nothing more. My client database looks like my brain, because I built it to match how I think about client work. Each client has a page. Inside that page: their intake responses, a running log of session notes, key themes I'm tracking, contract details, and a section I call "the real stuff," which is where I keep the observations that don't fit in a summary. The moment of silence that meant something. The thing they said while putting their coat on that was more honest than anything in the session.
No coaching platform has a field for that. Notion does, because I made one.
Here's the basic structure, for anyone who wants to steal it:
NOTION COACHING PRACTICE SETUP DATABASE: Client Roster Properties: - Name - Start date - Session cadence (weekly/biweekly/monthly) - Contract end date - Status (active/paused/completed) - Engagement type (individual/founder/organizational) - Referral source - Link to client page EACH CLIENT PAGE CONTAINS: ## Intake & Context - Pasted intake questionnaire responses - Initial goals (their words, not mine) - Organizational context - Key stakeholders mentioned ## Session Log (Each session is a toggle block with the date as the header) > Date: [date] > Pre-session review: what I wanted to pay attention to > Session notes: written within 10 minutes of ending > Key themes: 2-3 words max > Follow-up: anything I said I'd send or do > The real stuff: the moment that mattered, the thing under the thing ## Running Themes - A simple bulleted list I update every few sessions - What patterns am I noticing? - What are they not saying? ## Admin - Contract PDF (embedded) - Payment status - Scheduling notes (preferred times, timezone, etc.)
I do my session notes within ten minutes of each call. Sometimes right there at my desk, sometimes on the walk between sessions (voice memo, then I clean it up later, sometimes with Margaret's help to structure the raw notes into something I can scan quickly before the next session). The point is that the system serves how I actually work, not the other way around.
The downside is real, though. I built this over several weeks. There's no onboarding wizard. If Notion goes down (it hasn't, but still) I'm exposed. And there's no client-facing portal, which means anything I want to share with clients goes via email. For me that's fine. For coaches who want clients to log in and see their goals and progress, it's not.
A quick word about affiliate links and honesty
Some of the platforms I've mentioned have affiliate programs. Some links in reviews like this one are affiliate links. I want to be direct about that: my recommendations here are based on what I've actually used and what I've seen work for coaches I know. If you click a link and sign up, I might get a small referral fee. It doesn't change what I think, and I'd rather you use Notion for free than buy something that doesn't fit your practice because someone got paid to recommend it.
The thing nobody mentions: switching costs
Here's what I wish someone had told me before I signed up for my first coaching platform: the monthly fee is not the real cost. The real cost is that six months in, your entire client history lives inside that tool. Every session note, every contract, every intake form. And if you want to leave, you're either exporting CSVs and rebuilding everything somewhere else, or you're starting from scratch.
This is why I ended up on Notion. Not because it's the best tool. Because it's mine. I own the data. I own the structure. If something better comes along next year, I can move without losing anything.
Before you commit to any platform, ask yourself: if I want to leave in a year, what does that look like? If the answer makes your stomach tighten, that's information.
So what should you actually use?
If you're in your first year or two and selling packages directly to individuals: Paperbell. Get it set up in an afternoon, stop thinking about it, focus on your coaching.
If you work with organizations and need to show structured progress to sponsors: Simply.coach. The overhead is worth it for the reporting alone.
If you have an established methodology with clear milestones and you want a system that matches your rigor: CoachAccountable. Ignore the interface. It's the best at what it does under the hood.
If your main headache is proposals, contracts, and getting paid, especially with corporate clients: HoneyBook. Accept that it doesn't know what coaching is and use it for what it's good at.
If you've been doing this for a while and you know what you need: build it yourself in Notion (or something like it). Pair it with Calendly and Stripe. You'll spend more time on setup and zero dollars on a monthly platform fee, and you'll end up with a system that actually matches your practice instead of someone's idea of what your practice should look like.
That's not a recommendation for everyone. It's what's true for me after nine years and more cancelled subscriptions than I want to count.
What I'm still figuring out
I said earlier that AI features in coaching platforms are mostly not useful yet. I believe that. But I also know that my own setup, where I use Margaret to help with session note structure, prep summaries, and the occasional proposal draft, is basically me building the AI layer myself on top of Notion. There's a version of this where a platform does that integration well enough that it's worth switching. Simply.coach might get there. Someone else might get there first.
Right now my Notion page for a client I'm seeing this morning has every session we've had, the themes I've been tracking, and something she said three weeks ago that I flagged because I think it matters more than she realizes yet. No platform gave me that. I built it over time, keeping what served the coaching and dropping what didn't.
Your system will look different. It should.
