A $0 Tech Stack for Small Business: Free Tools and Limits

Yes, you can run a small business on a $0 tech stack. Free plans exist today for business email, a website, a simple CRM, invoicing, design, notes and passwords. The catch is the limits: small user counts, storage caps and branding. You also still pay for a domain name.

Below is a stack that works for a one- to five-person business, with each free plan's limits stated plainly. I checked every plan in October 2026. Free plans change often, so check the pricing page before you commit.

What "$0" really means

Three things are not free, even in a $0 tech stack:

• A domain name (like yourshop.my). You pay a yearly fee to a registrar.
• Your time. Free tools mean more setup and no phone support.
• Your data risk. If a free provider changes its terms, you need a way out. Export your data regularly.

Each tool and its limits

Business email: Zoho Mail Forever Free

Customers trust hello@yourshop.my more than a Gmail address. Zoho Mail's Forever Free plan gives up to 5 users, 5 GB of mail storage each, and email on one custom domain.

Limits: No IMAP, POP or Exchange sync, so you use Zoho's web and mobile apps instead of Outlook. A sixth user means everyone moves to a paid plan. The free plan is only offered in some data centres.

Website: Cloudflare Pages

For a simple company site, a static site (plain pages with no server code) on Cloudflare Pages costs nothing. The free plan allows 500 builds a month, 20,000 files per site and files up to 25 MiB.

Limits: You need some comfort with site builders or code. Contact forms need an extra service.

Note on Vercel: Vercel's free Hobby plan is generous, but its own pricing page says it is for personal, non-commercial use. A business site should use a paid plan or another host.

CRM: HubSpot free CRM

A CRM (customer relationship management tool) tracks who your customers are and where each deal stands. HubSpot's free tools cover up to 2 users and 1,000 contacts, with no time limit.

Limits: Free chat, email and meeting tools carry HubSpot branding. More users or contacts means paying.

Invoicing: Zoho Invoice

Zoho Invoice is free, with up to 500 invoices a year, 2 users and 3 projects.

Limits: Invoices show "Powered by Zoho Invoice". Zoho's page does not list a Malaysia edition, so check that it handles SST and e-invoicing for your business.

Design: Canva Free

Canva Free includes 5 GB of storage and over 1.6 million templates.

Limits: One brand kit with only 3 colours, up to 20 AI uses a month, and no premium templates or stock.

Notes and docs: Notion Free

Notion Free is good for SOPs, checklists and content plans.

Limits: Unlimited blocks for one person, but workspaces with two or more members have a block cap. Page history lasts 7 days, you can invite 10 guests, and uploads are capped at 5 MB each.

Email marketing: Mailchimp Free

Mailchimp's free plan suits a very small list: 250 contacts, 500 emails a month (250 a day) and one user.

Limits: No automation flows. Sending pauses if you go over a limit.

Passwords: Bitwarden Free

A password manager stops staff reusing weak passwords. Bitwarden's free plan gives an unlimited personal vault on unlimited devices, plus sharing with one other user.

Limits: Team sharing beyond one person needs a paid plan.

Google Business Profile

Your listing on Google Search and Maps is free to manage. For a café, clinic or workshop, it often brings more customers than the website.

Code and automation, if you have a developer

• GitHub Free gives private repositories and, for private repos, 2,000 Actions minutes a month. Actions are free on public repos using standard runners.
• Cloudflare Workers (small bits of server code) are free for 100,000 requests a day.

For when this kind of setup makes sense, see serverless computing explained.

Who a $0 stack suits, and who it doesn't

Good fit: sole traders, new shops, side businesses and small teams of up to about five.

Poor fit: businesses with strict compliance needs, teams that need audit logs and fine-grained permissions, or anyone without time to set things up.

Protect your free stack

Free does not mean low risk. Do these four things:

1. Turn on two-factor authentication everywhere.
2. Use the business email, not personal accounts, as the owner of every tool.
3. Export important data (contacts, invoices) monthly and keep a copy you control. See immutable backups.
4. Know where customer data is stored, since your PDPA duties still apply. See the data breach guide.

Conclusion

A $0 tech stack is realistic for a small business in 2026. Zoho Mail, Cloudflare Pages, HubSpot, Zoho Invoice, Canva, Notion, Mailchimp and Bitwarden all have working free plans. Know each limit before you hit it, budget for a domain and plan which tool you will pay for first as you grow.

Quick answers

Can a business really run on free software?

A small one can. Most free plans cap users, storage or volume, so expect to start paying as you pass about five staff or a few hundred customers.

Is Vercel's free plan OK for a business website?

No. Vercel says its Hobby plan is for personal, non-commercial use. Cloudflare Pages is a free option for a static business site.

What should I pay for first?

Usually a domain on day one, then whichever tool you hit the limit on first. For many shops that is email marketing or the CRM.

Is free business email safe?

It can be, if you turn on two-factor authentication and use strong, unique passwords. Check where the provider stores your data.
