There's a trap solo service owners fall into that has nothing to do with clients. You sign up for a 14-day trial of a $79/month all-in-one tool. You use 20% of it. You forget to cancel. Six months later you're paying for Dubsado, ClickUp, Mailchimp, and Zoom Pro — and somehow none of them know that a new client just signed a contract.
That was me in year two.
This post is what replaced that bloat. It's not the "best" stack for every solo operator — it's the stack that actually runs my business today. The total comes in under $50/month, and every tool earns its spot.
The $47/month stack, priced out
Here it is at a glance:
| Tool | Tier | Cost/Month | Job |
|---|---|---|---|
| Gmail + Google Workspace | Business Starter | $7.20 | Email, Drive, Calendar |
| Google Meet | Included | $0 | Video calls |
| Calendly | Free | $0 | Scheduling |
| Notion | Free | $0 | Client dashboard, SOPs, notes |
| Google Drive | Included above | $0 | File storage |
| Wave | Free | $0 | Invoicing + accounting |
| Stripe | Pay-as-you-go | 2.9% + 30¢/txn | Payment processing |
| Kit (ConvertKit) | Free (<1k subs) | $0 | Newsletter + automations |
| Canva | Free | $0 | Graphics + social posts |
| Buffer | Free | $0 | Social scheduling |
| Make.com | Core | $10.59 | Workflow automation |
| Zapier | Starter | $19.99 | Backup automations |
| Loom | Starter Free | $0 | Async video updates |
| Total | $37.78 + Stripe fees |
If you count transaction fees as "software," my real monthly number is closer to $47-$60 depending on invoice volume. I'm going to keep calling it a $47 stack because I hate hiding transaction fees.
Communication and scheduling: $7.20/month
I upgraded from free Gmail to Google Workspace Business Starter only when I wanted a hello@runitonautopilot.com address. Before that, a custom domain on Namecheap + free Gmail aliases did the job for about $1.50/month of domain cost.
Calendly's free tier gives you one event type. That's actually a forcing function. You decide what the one meeting your business needs is (kick-off call, intro call, office hours), and everything else goes through an email. Fewer calls. Better calls.
Google Meet is included with Workspace and, more importantly, it doesn't require your client to install anything. Zoom's install friction has cost me meetings. Meet has never lost me one.
Project and client management: $0/month
Notion is the single tool I'd pay the most to keep. It's where my client dashboard lives, where SOPs live, where the content calendar lives, and where I write every blog post before it goes to the site.
The free tier is plenty for a solo operator. I've been nudged toward the $10/month plan for page history, but weekly Time Machine-style backups solve that for free.
Google Drive is just Drive. I keep it dumb: one folder per client, one "Templates" folder, one "Admin" folder. Nothing clever. Clever folder structures are the number-one way to lose files.
Invoicing and money: ~$0 + Stripe fees
Wave is free and does invoices, expense tracking, and basic accounting. For a solo business under six figures, it is more than enough. I tried FreshBooks ($17/month) and QuickBooks ($30/month) and couldn't find a single task I could do faster on either.
Stripe's transaction fees are the real cost of getting paid — 2.9% + 30¢ on US cards, a bit more for international. I don't try to pass these on to clients. I priced it into my rates years ago.
Marketing and email: $0/month (for now)
Kit (the app formerly known as ConvertKit) is free up to 1,000 subscribers and includes one automation sequence. I'm still under the cap, but I'll be on the paid tier soon — and it'll be the best $29/month I spend.
Buffer's free plan lets you queue posts on three social channels. Canva's free plan does 90% of what you'd pay for. Don't get fancy here. The goal is consistency, not beautiful graphics.
Automation: $30/month combined
This is where most solo operators under-invest and overpay at the same time. They pay for premium all-in-one tools because they feel automated, then do the real connective work by hand.
Make.com (Core plan, $10.59/month) gets most of my complex workflows. Calendly booking → Notion dashboard update → Kit tag → Google Drive folder → welcome email. One scenario, 12 steps, runs whenever a new client books.
Zapier (Starter plan, $19.99/month) is for the simple one-step Zaps that would blow through Make's operation limits if I moved them. New form submission → add row to Google Sheet. New Stripe payment → thank-you email. Cheap work on the cheaper platform.
You don't need both on day one. I started on Make's free tier alone for the first year. Add Zapier only when you find yourself hacking simple things into Make because it's what you already know.
How the stack actually connects
A typical new-client day looks like this:
- Prospect books a discovery call through Calendly.
- Make fires a scenario that drops them into my Notion CRM as a "Booked" row and tags them in Kit as
discovery-scheduled. - After the call, I mark the Notion row "Won" — which Make picks up and triggers my onboarding flow: welcome email via Gmail template, intake form link, Google Drive folder auto-created.
- Client fills out the intake form. Apps Script (yes, still!) shares the folder with them.
- Wave generates the first invoice, which Stripe charges. Make catches the paid event and moves the Notion row to "Active" + sends a thank-you email with the kick-off agenda.
Everything between step 1 and step 5 is untouched by me. The whole chain took one focused Saturday to build.
What I cut to get here
Before this stack I paid for:
- Dubsado — $40/month. Great tool, wildly under-used by me.
- Mailchimp — $20/month. Clunky automations.
- Zoom Pro — $14.99/month. Unnecessary given Meet.
- Asana — $10.99/month. Notion replaced it entirely.
- Calendly Pro — $12/month. Multiple event types I didn't need.
- Loom Business — $15/month. Free plan is plenty for async updates.
That's $112.98/month of software that looked active on my statement but didn't actually do anything I needed. Cutting it felt like opening a window.
The mental model: "dumb tools, smart connections"
My rule now: use the simplest tool that does the job, then spend on the automation layer that connects them. A smart $15/month workflow that connects five free tools beats a $79/month app that does all five jobs adequately.
This stack will look different in a year. I'll almost certainly add a paid Kit plan once I hit 1,000 subscribers. I might add a dedicated contract tool like PandaDoc when I'm writing more than four proposals a month.
But the principle won't change. Every new tool has to justify itself — not by features, but by hours saved or dollars earned.
Frequently asked
Is this stack enough to replace Dubsado or HoneyBook? For a solo service owner under ~15 clients a year, yes. The Google Forms + Make + Wave combo covers intake, contracts, invoicing, and onboarding. You lose branded client portals, which I haven't missed.
What if I'm not technical? Make looks intimidating and isn't. The visual builder is closer to drawing arrows between sticky notes than writing code. My first useful workflow took 40 minutes to build.
How do I know when to upgrade a tool? I upgrade when I've hit a free-tier limit for three consecutive months and can trace specific lost hours or lost revenue to the limit. Feature envy is not a reason.
If you're starting from zero, the cheapest honest way into automation is: free Gmail, free Calendly, free Notion, Wave, Kit free, and Make free. Total first-month software bill: $0. Then add one paid tool per quarter only if you can justify it.
I also broke down Zapier vs. Make for non-developers in a separate post — worth reading before you commit to one automation tool over the other.
