The Solopreneur's Toolkit: What You Actually Need to Build a Side Business

Every "solopreneur toolkit" article I've ever read follows the same formula. They list 40 tools across 12 categories, half of which require enterprise pricing, and by the end you feel worse about your setup than when you started.

Here's the thing nobody writing those articles will tell you: most successful side businesses were built with five tools or fewer. The rest is procrastination dressed up as preparation.

I've watched hundreds of side hustlers go through the tool selection process. The ones who ship? They pick something simple and start working. The ones still "evaluating options" six months later? They have a Notion database comparing 30 project management apps and zero customers.

So let's talk about what you actually need.

The only categories that matter

When you're building something on the side of a full-time job, your tool stack needs to do exactly four things:

1. Tell you what to work on when you sit down
2. Let you build the thing
3. Let you put the thing in front of people
4. Let you get paid

That's it. Everything else is optional until you're making money.

I know that sounds reductive. It's supposed to be. The number one killer of side projects isn't bad tools. It's decision fatigue from choosing between too many of them.

Category 1: Know what to work on

This is the one most people get wrong because they confuse "project management" with "knowing what to do next." They're not the same thing.

Project management means breaking work into tasks, assigning deadlines, tracking dependencies, and generating status reports. That's useful when you have a team of eight. When it's just you, working three evenings a week after the kids go to bed, it's overhead.

What you actually need is something that answers one question: "I just sat down. What should I do right now?"

A study published in the Journal of Experimental Psychology found that switching between tasks costs an average of 23 minutes of refocusing time. For side hustlers, that 23 minutes might be a third of your entire session. You can't afford to spend it scrolling through a backlog trying to remember where you were.

Session Stacker was built specifically for this problem. You log what you did at the end of each session and it tells you exactly where to pick up next time. No Gantt charts. No sprint planning. Just "here's what past-you said to do."

But even if you use something else, a sticky note, a text file, whatever, make sure it does this one job well. The specific tool matters less than having an answer ready the second you open your laptop.

What works: Session Stacker, a dedicated notebook, Apple Notes, a single pinned Slack message to yourself

What's overkill: Jira, Monday.com, Asana (unless you already know them cold)

Category 2: Build the thing

This depends entirely on what you're building, so I'll keep it short.

If you're building software: pick one framework and learn it. Next.js, Rails, Laravel, whatever your friends use so you can ask them questions. The "best" framework is whichever one you'll actually finish something with.

If you're building a service business: you need a way to deliver your work and communicate with clients. Google Workspace covers both for $7/month.

If you're selling physical products: Shopify. Yes, there are cheaper options. No, the $39/month isn't going to kill your margins unless you're selling things for $2 each.

The pattern here is the same: pick the boring, obvious choice and move on. Nobody ever failed because they chose Shopify over WooCommerce. Plenty of people failed because they spent two months comparing them.

One thing I'd add: whatever you build with, make sure you can ship incremental updates. Don't disappear for three months building in secret. Get something ugly in front of real people fast. The MVP approach applies to every category of side business, not just software.

Category 3: Get it in front of people

Here's where most solopreneur tool lists go off the rails. They'll recommend a social media scheduler, an email marketing platform, an SEO tool, a landing page builder, a webinar platform, an analytics suite, and a CRM.

You need maybe two of those.

When you're starting out, your job isn't "marketing." Your job is getting 10 people to try your thing. Then 50. Then 100. The tools that help at 10 users are completely different from the tools that help at 10,000.

At 0-100 users, you need:

A landing page. Carrd ($19/year) or a free Vercel deploy if you can write HTML. Don't pay $49/month for Unbounce when you have 12 visitors a day.

A way to talk to potential customers directly. Twitter/X, Reddit, relevant Discord servers, or wherever your people hang out. No scheduler needed. Just show up and be helpful. Building in public works here because it's free and it compounds.

An email list. Buttondown (free tier) or Mailchimp (free under 500 contacts). Start collecting emails on day one even if you have nothing to send yet. You'll thank yourself later.

At 100-1,000 users, add:

An analytics tool so you know where people come from. Umami (free, self-hosted) or Plausible ($9/month) are both privacy-friendly and way less overwhelming than Google Analytics.

A proper email platform if you've outgrown the free tiers. ConvertKit or Resend, depending on whether you want pretty templates or API control.

At 1,000+ users, then worry about:

SEO tools, social schedulers, CRMs, paid ads, and all the other stuff those 50-item toolkit lists recommend. Not before.

Category 4: Get paid

Stripe. That's the recommendation. I know, groundbreaking advice.

If you're selling physical goods, your platform (Shopify, Etsy, etc.) handles payments. If you're selling digital products or services, Stripe plus a checkout page is all you need.

Lemon Squeezy and Gumroad are fine alternatives if you want something more turnkey. Paddle handles sales tax for you, which matters once you're selling internationally.

Don't set up accounting software until you have revenue. A spreadsheet works until you're doing enough volume that it doesn't. Wave is free when you get there.

The tools nobody talks about that actually matter

Here's what I think gets underweighted in every toolkit discussion.

A timer or session tracker. Not because time tracking itself is useful, but because it creates accountability. When you can see that you worked 47 minutes on Tuesday and 0 minutes the rest of the week, it's harder to lie to yourself about "being busy." Streaks and consistency tracking do more for output than any project management tool.

A "parking lot" note. Somewhere you dump ideas, feature requests, and random thoughts so they stop rattling around your head during work sessions. I use a single text file called ideas.txt. When it gets long, I delete half of it. Most ideas that seemed urgent a month ago look ridiculous now.

A second brain that isn't Notion. Controversial take: Notion is where side projects go to die. It's an incredible tool that rewards you for organizing information instead of acting on it. If you can use Notion with discipline, great. Most people can't. They spend Saturday afternoon building a database of competitors instead of emailing one potential customer.

Try something dumber. Apple Notes. A paper notebook. Obsidian if you want to feel technical about it. The goal is capturing thoughts fast, not building a personal wiki.

My actual stack (for reference)

Here's what I use to run a side business on roughly 10 hours a week:

• What to work on: Session Stacker (obviously)
• Building: VS Code + Next.js + Vercel
• Getting found: Twitter/X + this blog + word of mouth
• Getting paid: Stripe
• Email: Resend
• Analytics: Umami (self-hosted)
• Notes: Apple Notes + a physical notebook
• Communication: iMessage and email. No Slack. No Discord server. Not yet.

That's eight things. Three of them are free. The total monthly cost is under $30.

Could I add more? Sure. A CRM would help me track leads better. A social scheduler would save time. Better SEO tools would probably help with organic traffic.

But here's what I've learned: every tool you add creates maintenance. Updates, integrations, learning curves, subscription costs, and one more tab fighting for your attention. When you're a solopreneur working evenings and weekends, every minute counts.

How to evaluate any new tool

Before adding anything to your stack, ask three questions:

Does this solve a problem I have right now? Not a problem I might have someday. Not a problem someone on Twitter told me I should worry about. A problem that's actively slowing me down this week.

Can I set it up in under an hour? If the onboarding process is longer than one of your work sessions, it's too complex for your current stage. Come back to it when you're bigger.

Will I actually use it consistently? Be honest. How many tools have you signed up for, configured once, and never opened again? That $15/month "deal" costs $180/year to collect digital dust.

If the answer to all three is yes, go for it. If not, close the tab and get back to work.

The uncomfortable truth about solopreneur productivity tools

The best toolkit is the one you stop thinking about.

You know how you never think about your kitchen faucet? It works, you use it, you move on with your day. That's what your tool stack should feel like. The moment you're spending more time configuring tools than using them to build your business, something's wrong.

Pick boring tools. Pick obvious tools. Pick tools that do one thing well and get out of your way. Then go build something worth selling.

Your side hustle doesn't need a better stack. It needs you to sit down and do the next thing.
