Plenty of small businesses run on Notion and a Gmail tab: a client database you built, a proposal template you duplicate, and an inbox somewhere else. BusinessOS is the version where the inbox, the clients and the proposals are one thing, and an agent keeps them in step.
14 days free. No card needed.
Judged for a business of one to five people that sells its time: a studio, a consultancy, a trade, a practice.
| Capability | Notion | BusinessOS |
|---|---|---|
| What it is | A connected workspace for notes, docs, projects and wikis. | One workspace for a small service business, run by an agent that asks before it acts. |
| Notion Mail, free, for Gmail. Outlook is not supported. | Gmail and Microsoft 365, or email on your own domain with no outside mailbox at all. | |
| Calendar | Notion Calendar, free. | Yes, with Gmail or Microsoft 365. Bos drafts the invite with a Meet or Teams link. |
| Clients | A database you design yourself, or a template. | Contacts and companies kept current from signatures, invites and meeting transcripts. |
| Proposals | A page you write and share. | From templates, shared as a link the client opens and accepts online. You see when it is opened. |
| Tasks | Databases with subtasks and dependencies, as elaborate as you like. | A board with a Needs approval column. Follow-ups are created from emails, meetings and proposals. |
| Website | Notion Sites, which publishes your pages as a simple site you design yourself. | Built for you from your business profile and hosted. Change the wording in the editor or ask Bos. |
| AI | Notion Agent on Business. Custom Agents run on schedules, paid in credits. | Bos is included. It drafts, triages and chases, and nothing is sent without your approval. |
Built for the business that is mostly you, not for a team that needs coordinating.
Notion Business is docs, projects and Notion Agent, per member, with email through Gmail, and the website is yours to build. BusinessOS is the whole workspace and Bos, email on your own domain, and a website built for you, hosted and kept up to date.

Paying monthly, before tax. Notion prices are from its own pricing page in October 2026 and are charged in pounds. Squarespace Basic is a builder you design and write yourself; its price is from the same month. Our website is £49 once to build, and a domain you register through us is at cost. Pay annually and every BusinessOS monthly charge is 20% off.
If one of these is you, use Notion. It is good at what it is for.

For running the client side of a small service business, yes: the inbox, contacts, proposals and follow-ups. As a wiki or a place to write, no, and plenty of people use both. BusinessOS replaces the client database and proposal template you built in Notion, not your handbook.
No. Connect your inbox and Bos reads your recent history and fills in your contacts and companies, from signatures, calendar invites and meeting transcripts.
Not on the sticker. Notion Business is £16.50 a member a month, and BusinessOS is £54 a month for everything including your first user, then £19 for each extra person. The difference is what that covers: email on your own domain, your website hosted, client records that keep themselves current and proposals your client accepts online. With Notion you build those yourself or pay for them elsewhere.
No. Bos drafts replies, proposes meetings and suggests tasks. Nothing is sent, and no invite goes out, without your approval. Every action Bos takes is recorded in the activity log.
Not for BusinessOS. Connect Microsoft 365 (Outlook) or Gmail over OAuth, and the calendar comes with it.
Yes. 14 days with every feature, and no card needed to start.
