Best Tools for Independent Consultants: CRM, Email and Booking
When you first start your consulting practice, it’s natural to do everything by hand. You reply to every email personally, send invoices as Word documents, and coordinate meeting times back and forth until something finally sticks. There’s even something lovely about that season of building, when everything feels close and personal.
But there comes a point where the right tools don’t make your practice feel less personal. They make it feel more intentional. When your booking link is in your email signature, a client can choose a time that genuinely works for her without any back-and-forth. When your invoice goes out automatically, you don’t have to think about it. When your welcome email arrives in a new subscriber’s inbox the moment she signs up, she feels seen and cared for, even while you’re with another client.
That’s what a good tech stack does. It creates space for you to be fully present in your work, because the background details are taken care of.
This guide walks through four categories of tools, each with options at different price points, so you can build a setup that feels right for where you are right now.
A gentle reminder: You don’t need to set everything up at once. Choose one tool, get comfortable with it, and let it settle before adding the next. There’s no rush.
Part 1: The all-in-one option, CRM, proposals, invoices, booking and forms
Some platforms are designed to be a single, calm home for your entire client relationship. From the first enquiry to the final invoice, everything lives in one place: your contact list, your proposals, your contracts, your booking calendar, and your intake forms.
For many consultants, especially those who are just getting started or who prefer simplicity over customisation, this kind of all-in-one platform is a wonderful place to begin. One login. One dashboard. One place to look when you want to know where things stand with a client.
The gentle tradeoff is that no single feature within an all-in-one will be quite as refined as a tool built for that one specific job. But for most practices, that’s a more than worthwhile exchange for the ease of having everything together.
A good fit if:
- You’re setting up your tools for the first time and want to keep things simple
- You work with a manageable number of clients and want a clear overview of each relationship
- You’d love one place where all your client information lives, rather than across several apps
- You want to spend your energy on your clients, not on learning five different platforms
17hats | $45–65/month | For consultants who love a well-organised workflow
17hats has a loyal following among independent professionals who appreciate thoughtful automation. You can build gentle workflows that unfold on their own: when a new enquiry arrives and a form is completed, a proposal goes out; when it’s signed, the invoice follows; when payment is received, your onboarding materials are sent.

HoneyBook | $16–66/month | Beautifully designed for independent service providers
HoneyBook was created for people who work for themselves, and it genuinely shows. The experience it creates for your clients is warm and professional: they receive a beautifully formatted proposal, sign their contract, and pay their invoice all within a single branded portal, without needing to create an account. The workflow follows a natural rhythm: enquiry, proposal, contract, invoice, project. If you’d love your clients to feel looked after from their very first interaction, HoneyBook is a joy.
Includes: Contact and pipeline management · Proposals and contracts · Invoicing and payments · Booking and scheduling · Intake forms · Client portal
HubSpot | Free CRM / $20–45/month (Starter) | Generous, reliable and grows with you
HubSpot’s free CRM is one of the most capable tools available at no cost. It handles your contact list, your pipeline, meeting scheduling, email tracking, and intake forms beautifully. As your practice grows, the Starter plans bring in email sequences, automation, and richer reporting. HubSpot wasn’t designed specifically with consultants in mind, but its warmth and reliability make it a steady foundation for almost any practice.
Includes: Contact and pipeline management · Booking via meetings tool · Intake forms · Basic email marketing · E-sign (available as a paid add-on)
Part 2: Email marketing, MailerLite and Kit (ConvertKit)
Your email list is something truly yours. Unlike followers on any social platform, the people on your list have chosen to hear from you directly, and nothing sits between you and them. A short, genuine email to a few hundred people who know and trust your work can open more doors than any amount of posting online.
For consultants, email is also the quietest and most natural way to stay connected with past clients between engagements. A monthly note sharing a thought, a resource, or a gentle update reminds people that you exist and that you care, without any pressure attached.
A small note: if you’re already using an all-in-one CRM like HubSpot, you’ll have basic email marketing included. These tools are worth exploring when you’re ready for a little more depth, such as segmenting your list, building automated welcome sequences, or creating dedicated landing pages.
What makes MailerLite especially lovely for consultants is how much is available without any cost. You can set up a welcome sequence that greets new subscribers warmly, segment your list by interest or source, and see exactly what’s resonating with your readers. For most consultants with a list under 1,000 people, it’s an easy and natural choice.
A good fit for: Consultants who want thoughtful automation without any upfront cost. Free up to 1,000 subscribers.
Kit (formerly ConvertKit)
Kit was built with independent professionals and creators in mind, and it shows in the way it thinks about relationships. Rather than treating your list as a single audience, Kit encourages you to understand your subscribers individually: what they’re interested in, what they’ve clicked on, what they’re ready for. From there, you can send content that feels genuinely relevant to each person.
The free plan is exceptionally generous, covering up to 10,000 subscribers with unlimited landing pages and forms. Paid plans ($25/month) bring in visual automation builders, where you can map out a subscriber’s journey in a way that feels both creative and clear. Kit also has a growing network of newsletters that recommend each other, which can be a beautiful way to grow your audience organically.
A good fit for: Consultants who are nurturing a thought leadership presence and want their email list to grow into a real, engaged community. Free up to 10,000 subscribers.
How to choose: MailerLite is a wonderful place to start if you want something simple and free. Kit is a lovely choice if you’re building a wider audience and want your email list to become a meaningful part of your practice.
Part 3: Booking and scheduling, Calendly and OnceHub
How to choose: Calendly is a lovely, simple choice for solo consultants. Come to OnceHub when you have a team and want to route client bookings with more care and precision.
Part 4: Staying connected with clients, Loom, Slack and Notion
Email will always have its place for formal communications and document sharing. But the everyday rhythm of a consulting engagement, checking in on progress, sharing thoughts on a draft, answering a quick question, often flows more naturally through tools designed for that kind of conversation. The three tools below each play a different role, and together they make for a very connected and organized way of working with clients.
Loom, gentle video walkthroughs and feedback
Loom lets you record your screen, with your face visible in the corner, and share the video instantly through a link. There’s no file to download or upload. You press record, walk through what you’d like to share, and send the link when you’re done.
For consultants, Loom can replace a surprising number of calls. Walking a client through a strategy document? A Loom is often clearer and kinder than a long written explanation. Sharing detailed feedback on something she’s sent you? A Loom lets her hear your tone and see exactly what you’re referring to. Explaining the thinking behind a recommendation? Recording it means she can revisit it in her own time. A four-minute video can carry more warmth and clarity than any email.
The free plan includes 25 videos with unlimited viewers. The paid plan ($12.50/month) removes the video limit and adds viewer insights and transcript editing.
Best for: Sharing feedback, walking through deliverables, onboarding new clients, and any time a written explanation would feel too flat.
Slack, a shared space for active projects
Slack works beautifully for engagements where you and your client are in regular conversation: a longer project, an ongoing advisory relationship, or any work where questions and updates come up naturally throughout the week. You create a shared channel together and the conversation moves out of email into a space that feels lighter and more collaborative.
One of the quieter benefits of Slack is that it keeps your whole project conversation in one searchable place. When you need to find a decision that was made a month ago, it’s there. Clients who already use Slack in their own organisations will feel immediately at home, and often appreciate the sense of working alongside you rather than simply emailing back and forth.
The free plan keeps 90 days of message history, which is usually enough for a project engagement. The Pro plan ($7.25/user/month) is worth considering for longer retainer relationships where you’d like to keep the full history.
Best for: Ongoing engagements where regular, easy conversation is part of how you work together.
Notion, a shared home for your project documents
Notion works beautifully as a shared workspace for each client relationship. You can keep your meeting notes, project brief, research, deliverable drafts, and action items all in one place, beautifully organised and easy to navigate. Clients can leave comments directly on any piece of content, which keeps feedback tidy and connected to the work itself rather than living in a separate email thread.
Beyond client work, Notion also makes a wonderful personal knowledge base. A page for each client, linked resources, reusable frameworks, notes from conversations. Over time it becomes a quiet, growing record of everything you’ve learned and created across your practice.
The free plan is generous and covers most needs beautifully. The Plus plan ($10/month) adds full version history and more advanced database features.
Best for: Document collaboration, project organization, meeting notes, and keeping your own knowledge beautifully in order.
Here are two approaches depending on where you are in building your practice:
Option A: A calm, all-in-one beginning (from $16/month)
Ideal if you’d like one place to come home to before you start adding specialist tools.
All-in-one platform HoneyBook (proposals, invoices, booking, forms, CRM) → $16/month
Email marketing MailerLite → Free
Client communication Loom and Notion → Free
Monthly total → Around $16/month to begin
Option B: A considered, best-in-class setup (from $29/month)
A lovely choice once you know your rhythms and want the best possible tool for each part of your practice.
CRM HubSpot Free → $0/month
Email marketing Kit (ConvertKit) → Free up to 10,000 subscribers
Booking Calendly Standard → $10/month
Proposals and contracts PandaDoc Starter → $19/month
Client communication Loom, Slack and Notion → $0–20/month
Monthly total → Around $29–49/month
The truth: Either approach will serve you far better than no approach at all. What matters most is simply choosing and beginning. You can always refine as you go.
Where to start
If you’re not sure where to begin, here is a simple, unhurried sequence:- Day one: Set up a booking link with Calendly and add it to your email signature. It’s one of the smallest changes that makes the biggest difference.
- Day two: Create a free MailerLite account and send your first email to the people who already know you. It doesn’t need to be perfect. It just needs to be sent.
- Day three: Record your first Loom and send it to a client in place of a long written message. Notice how it feels for both of you.
- The following week: Choose your CRM, either HubSpot Free or HoneyBook, and bring your contacts into it.
