The One-Person Business Stack in 2026
TL;DR
- The total SaaS costs for a solo business can be around $100-$125/month for a clear stack of essential tools, including payments, CRM, email marketing, hosting, and customer support.
- Stripe is the recommended payment solution, with a 2.9% + $0.30 per transaction fee and no setup or monthly costs, making it suitable for solo founders with annual revenue below $50,000.
- Kit (formerly ConvertKit) is a suitable email marketing solution, with pricing plans starting at $25/month for the Creator plan, which includes full automation, and scaling up to $50/month for the Creator Pro plan with additional features.
There has never been a cheaper time to run a serious solo business. The tooling that used to require a team to manage — payments, CRM, email marketing, hosting, customer support — can now be handled by one person with a clear stack and about $100–$125/month in SaaS costs. Here is the opinionated list I would build today, with real prices and the reasoning behind each choice.
Payments: Stripe ($0 + transaction fees)
Stripe is the only answer for a solo founder in 2026. It handles one-time payments, subscriptions, invoicing, payment links, and a basic customer portal out of the box. The 2.9% + $0.30 per transaction is expensive at scale, but at sub-$50K annual revenue it is the right tradeoff — zero setup cost, zero monthly fee, and the developer experience is 10 years ahead of its competitors.
Set up: a payment link for each product SKU, Stripe billing for recurring revenue, and turn on the customer portal so subscribers can manage their own billing. This eliminates a category of support requests entirely.
If you get to $150K+ ARR, the 2.9% starts to hurt and you should look at negotiating custom pricing or moving some volume to a processor with lower rates. Below that, the operational simplicity of Stripe is worth the fee.
Email Marketing: Kit (formerly ConvertKit) — $25–$50/month
For a solo business built around an audience — newsletter, course, community — Kit is the best balance of power and simplicity at this price point. The automation builder is genuinely good, the deliverability is consistently strong, and the subscriber tagging model is flexible without requiring a full CRM.
The free tier covers up to 10,000 subscribers but lacks automation. The Creator plan at $25/month gives you full automation; Creator Pro at $50/month adds subscriber scoring and priority support. Both scale with list size above the base tier.
Alternatives worth considering: Beehiiv if you want built-in newsletter monetization and a publication-focused UI; Brevo (formerly Sendinblue) if you need transactional plus marketing email in one platform at a lower price point.
CRM: HubSpot Free (or Pipedrive at $15/month)
A one-person business does not need a heavy CRM. HubSpot's free tier — up to 1 million contacts, basic pipelines, email tracking — covers most solo founders until they are doing serious B2B sales volume. The catch: it pushes you toward paid products constantly and the free tier has data limits that become annoying around deal 50.
If you do any meaningful B2B pipeline work, Pipedrive at $15/month is cleaner, faster, and does not try to upsell you at every turn. The pipeline UI is genuinely the best in the market at this price. Plug it into Zapier or Make for $10/month and it talks to everything else in your stack.
Hosting and Site: Ghost + Netlify — $9–$25/month
Ghost at $9/month (Starter) handles blog and newsletter publishing with a built-in subscription layer. If you want a full static site plus blog, pair Ghost with a Netlify-hosted marketing site — Netlify's free tier covers most traffic levels for a solo founder's site. Ghost handles the content; Netlify handles the landing pages.
If you do not need a blog and want a no-code site builder, Framer at $15/month produces genuinely professional results without design skills. It has surpassed Webflow for solo creator use cases for most people I know.
AI Tooling: Claude Pro + Perplexity Pro — $40/month combined
This is the highest-leverage $40 in the stack. Claude Pro ($20/month) handles writing, code review, research synthesis, document drafting, and long-context document work that used to require hiring a specialist. Perplexity Pro ($20/month) handles real-time research — market sizing, competitor analysis, trend tracking — with citation links that let you verify claims.
Together they replace: a junior copywriter, a research assistant, and a significant portion of a developer's time on routine work. At $40/month, the ROI calculation is trivial for any solo business doing $50K+/year.
Customer Support: Plain ($12/month)
Plain (plain.com) is the best solo-founder support tool right now — clean inbox UI, email plus chat unified, excellent keyboard shortcuts, and $12/month for a solo seat. It connects to Stripe so you see a customer's billing history inline when they email you.
If volume is very low (under 20 support conversations per week), just use a dedicated support@ Gmail and move on. Do not over-engineer support tooling until volume demands it.
Scheduling: Cal.com Free
Cal.com's open-source hosted free tier handles most scheduling needs. If you need round-robins, team routing, or paid booking, their paid tiers start at $12/month. It is cleaner than Calendly and the free tier is more generous.
The Total
Stripe ($0 + fees) + Kit Creator ($25) + Pipedrive ($15) + Ghost Starter ($9) + Netlify (free) + Claude Pro + Perplexity Pro ($40) + Plain ($12) + Cal.com (free) = roughly $101/month for a complete, professional business infrastructure. Add Make at $10/month for automation glue between the tools and you are still under $115.
Five years ago this stack would have cost $500–$800/month and required a technical co-founder to manage it. The stack above runs a newsletter business, a consulting practice, a course creator operation, or a small productized service. What it does not run: a marketplace, a hardware company, or a business with a real sales team. For those, you will outgrow it — but outgrowing a cheap, well-chosen stack is a good problem to have.
