What One Person Actually Needs to Run a Business in 2026
Running a one person business has never been more doable, and it’s never been easier to drown in tools you don’t need. Every week brings a new app promising to change everything, and the temptation is to assemble a sprawling stack of subscriptions that quietly drains your bank account and your attention.
You don’t need most of it. A lean, fully functional solo business runs on four categories of tools, two solid options in each, and if you’re careful you can do the whole thing for under $50 a month. Here’s the practical stack, what each option costs, and what you can skip when you’re just starting.
Category One: Money In and Out
You need to send invoices, get paid, and keep your books clean enough that tax season isn’t a crisis. This is the category not to cheap out on, because it’s about getting paid.
Wave is the budget pick and it’s genuinely good. Invoicing and accounting are free, and you only pay a small percentage when a client pays by card. For a new solo operator with a handful of clients, free accounting that looks professional is hard to beat. The step up is QuickBooks Solopreneur, around $20 a month, which adds proper bookkeeping, mileage tracking, quarterly tax estimates, and the reports your accountant will actually want. Start with Wave. Move to QuickBooks when the volume or the tax complexity justifies the cost, usually once you’re consistently profitable.
Category Two: Getting the Word Out
You need a place to live online and a way to talk to people who care about what you do. That’s a simple website and an email list, and you do not need a fancy custom build.
Carrd is the dirt cheap option, around $19 a year, not a month, for a clean one page site that’s perfect for a solo brand, a portfolio, or a simple landing page. For email, MailerLite has a free tier that covers your first 1,000 subscribers with automation included, and paid plans start around $10 a month once you grow past that. The combination of a Carrd site and a MailerLite list gives you a real online presence and a direct line to your audience for almost nothing. Skip the expensive website builders and the all in one marketing suites until you’ve actually got an audience to justify them.
Category Three: Getting the Work Done
You need to manage your tasks and projects and keep your documents and notes in one findable place. The trap here is over engineering, building an elaborate system you spend more time maintaining than using.
Notion is the all in one workspace, free for individual use, and it handles notes, docs, a simple task board, and a lightweight client database in one place. For most solo operators the free plan is plenty. If you prefer a dedicated task manager, Todoist is clean, fast, and free for the basics, with a pro tier around $4 a month. Pick one. Do not run both. A solo business needs a place to think and a place to track work, and either of these covers both well enough to start.
Category Four: Talking to Clients and Yourself
You need to schedule meetings without the back and forth, and you need a professional email address and basic file storage. This is the glue category.
Calendly handles scheduling, and its free tier lets people book time with you off your real calendar, killing the endless “does Tuesday work” email chain. For email and storage, Google Workspace at around $7 a month per user gets you a professional address at your own domain, a generous chunk of cloud storage, and the documents, sheets, and video calls you already know how to use. Together that’s a polished, professional front end for client interaction that costs less than two coffees a month.
Adding Up the Lean Stack
Run the numbers on the truly lean version and it’s striking. Wave for money, free. Carrd for the site, about $1.60 a month spread out. MailerLite free under 1,000 subscribers. Notion free. Calendly free. Google Workspace at $7. That’s roughly $9 a month to run a real, professional one person business with invoicing, a website, an email list, project management, scheduling, and a professional email address.
Even the upgraded version stays cheap. Swap in QuickBooks at $20, add a paid MailerLite plan at $10, keep Google Workspace at $7, and you’re around $37 to $40 a month with serious bookkeeping and a growing email list. Still comfortably under $50.
What to Skip Early
A few things people buy too soon. You don’t need paid project management software with a five person plan when it’s just you. You don’t need a CRM until you have enough clients that you’re forgetting follow ups, and even then a Notion table works for a while. You don’t need expensive design software when free tools cover a logo and basic graphics. And you don’t need a separate tool for every single function. Consolidation is your friend when you’re one person, because every tool you add is another login, another bill, and another thing to maintain.
The Real Lesson
The goal isn’t the most impressive stack. It’s the cheapest stack that doesn’t get in your way. Start lean, under $10 a month is genuinely possible, and only add a tool when a specific, recurring pain point demands it. Let your business pay for its own upgrades. A bloated stack is a tax you pay for tools you were too optimistic to skip, and the leanest operators are usually the ones who kept the most money.
