You do not need expensive software to get clients from the internet. A working sales funnel is one offer, one free resource, a few simple pages, five emails and a booking link, and you can build all of it on free plans. Here are the eight steps we use with coaches, consultants and solo founders, the free tools for each, and the point where paying starts to make sense.
To build a sales funnel for free, pick one offer and one ideal client, create a small lead magnet, and use a free plan like Systeme.io or MailerLite for the opt-in page and a five-email welcome sequence. Add a free Cal.com booking page, choose one free traffic source, and track four numbers weekly.
Who this is for: Coaches, consultants and solo founders who want a working funnel without a monthly software bill.
Yes. A sales funnel is just the path a stranger takes to become a client: they find you, they take something free, they hear from you for a few days, and they book a call or buy. None of that needs expensive software. It needs one clear offer and a few simple pages that join up.
What it does cost is your time. Free plans have limits, and you will do the setup, the writing and the checking yourself. For a coach, consultant or solo founder with a small list, that trade is often worth it. You learn what works before you pay for anything.
If you have never mapped a funnel before, our guide on how to set up a sales funnel covers the basics. This article is the tight-budget version: eight steps, a free tool for each job, and a clear line on when to start paying.
Every cheap funnel that works starts narrow. Choose the one offer you most want to sell, such as a 12-week coaching programme or a fixed-price consulting project. Then choose the one person it is for, described the way they would describe themselves: "a new manager who dreads one-to-ones", not "professionals seeking growth".
Write one sentence: "I help [person] get [result] without [the thing they hate]." Every page, email and post in your funnel will repeat this idea. If you try to serve three audiences with one funnel on a free plan, you will run out of pages, automations and energy fast.
Your lead magnet is the free thing people swap their email for. It should solve a small, real piece of the problem your paid offer solves, so the people who take it are the people who might buy. A checklist, a one-page template, a short video or a five-question self-assessment all work.
Keep it quick to use. A 40-page ebook feels generous but rarely gets read. A one-page "pricing script for your first discovery call" gets used the same day, and that is when people start to trust you. You can build it in Google Docs or Canva's free plan and export it as a PDF. Our lead magnet funnel guide has more on choosing the right one.
The opt-in page has one job: get the email. It needs a headline that names the result, three short bullets on what they get, a picture of the lead magnet and one form. No menu, no links away, no life story.
Systeme.io's free plan and MailerLite's free plan both include landing pages with forms that feed straight into your email list, so you do not need a separate page builder. Carrd is lovely for simple pages, but forms and custom domains need a paid Pro plan, so it is not the zero-cost option for this step.
Most people waste the thank-you page with "Check your inbox". This is the moment someone is most interested in you, so give them a next step. For a high-ticket coach or consultant, that is a short video and a button to book a call. For a lower-priced offer, it could be a small paid first step, such as a 60-minute strategy session or a mini course.
Keep the delivery of the lead magnet on this page too, as a download link, so nobody is stuck waiting for an email that went to spam.
The welcome sequence does the warming up you cannot do one to one. Five emails over about ten days is plenty. Here is a simple outline:
Write them like letters to one person, in plain text. Short emails that ask a question often get replies, and replies are the warmest leads you will ever have.
A booking page saves you the back-and-forth of "does Tuesday work?". Cal.com's free plan for one person includes unlimited event types, and its docs show you can add custom booking questions. Calendly's free plan gives you one event type, which is enough if you only offer one kind of call.
Ask just two questions before someone books: "What is the main thing you want help with?" and "Roughly when are you hoping to start?". Two questions filter out time wasters without putting off good people. More than that and your booking rate drops.
A funnel with no visitors is just a nice set of pages. Choose one free traffic source and stick with it for at least eight weeks:
Pick the one you will still be doing in month three. Consistency beats variety on a tight budget.
You do not need a dashboard. A free Google Sheet with four columns is enough: visitors to the opt-in page, new subscribers, calls booked and clients won. Fill it in every Friday.
Those four numbers tell you where the funnel leaks. If lots of people visit but few sign up, fix the opt-in page. If people sign up but nobody books, fix the emails or the thank-you page. Our free funnel leak calculator shows which stage is costing you most, and the conversion rate calculator turns your weekly counts into rates.
Here is a free stack that covers every job above. Plan limits are taken from each vendor's own pricing page at the time of writing (October 2026), and they change often, so check before you build.

Our pick for most coaches starting from zero: Systeme.io free for the pages and emails, Cal.com free for bookings, and a Google Sheet for the numbers. That is the whole funnel for nothing. If you want to compare paid builders when you outgrow it, see our guide to the cheapest funnel builders.
Free tools cost nothing on the invoice, but they are not free. Be honest with yourself about three costs before you start.
None of these is a reason not to start. They are reasons to choose tools you can grow into, and to know your exit point in advance.
Spend money when it removes a bottleneck you can see in your four weekly numbers, not before. A few clear signs:
Who should not bother with the free route? If you already have a waiting list, a strong referral flow or a budget for ads, building everything yourself on free plans is probably a false saving. Spend on one paid all-in-one tool or on help, and put your time into sales. For more on what a funnel looks like when it is built for a coaching business, read our guide to a sales funnel for coaches.
The free route is right when you are testing an offer, have more time than money, and enjoy learning the tools. It is the wrong route when the funnel has already proved it can work and you are the bottleneck, or when a missed month of leads costs more than the build would.
That is where a done-for-you studio like Unbury fits. We find where your marketing is losing people, build the fix (the offer, the pages, the emails, the follow-up) and run it with you week to week. If you would like to know which of your funnel stages is leaking first, start with a free audit and we will show you, with no obligation to buy anything.
Pick one offer and one ideal client, create a small lead magnet, and build an opt-in page and welcome emails on a free plan such as Systeme.io or MailerLite. Add a free booking page with Cal.com or Calendly, choose one free traffic source, and track four numbers weekly in Google Sheets.
For most coaches and consultants, Systeme.io's free plan is the most complete at the time of writing, with up to 2,000 contacts, 3 funnels and unlimited emails. MailerLite's free plan is a good alternative if you mainly need email and one landing page. Limits change, so check the pricing pages first.
Keep it narrow: one offer, one person, one lead magnet that solves a small piece of the same problem. Use the thank-you page to invite a call, write five plain welcome emails, and fix the stage that leaks most each week. Focus beats more tools.
Most solo founders can set up the pages, emails and booking link in a few focused days. Getting enough traffic and learning what converts usually takes a couple of months of steady posting or outreach.
Upgrade when a free limit is blocking growth you can see, such as hitting a contact cap or needing a second email sequence. If one new client would easily cover a year of a paid plan, the upgrade has paid for itself.
Send us your setup and we will tell you honestly where it is leaking customers and what to fix first. Free, no pitch.
