Your whole business, one login.

BizOS is the business operating system we build and run. Online store, website, POS, stock, accounting, business email, marketplace and AI — connected, so a sale in one place updates everything else automatically.

Features

Everything a small business runs on.

Sell

Online store

A branded, mobile-first storefront on your own domain or a free yourname.bizos.uk address. Cart, checkout and Stripe card payments built in.

Website builder

Not selling online? Build a full business website with drag-and-drop blocks — hero, text, gallery, contact form, map — or custom HTML pages, and choose your own homepage and menu.

Point of sale

Turn any tablet, laptop or phone into a till. Cash, card or split payments, receipts and returns — synced to stock and books instantly.

SEO built in

Per-page titles and descriptions, clean URLs, automatic sitemap and robots.txt, product structured data for Google, and fast pages behind Cloudflare.

Operate

Warehouse & stock

Multi-location inventory that deducts on every online or POS sale. Low-stock alerts and one-click purchase orders.

Automatic accounting

Every sale, refund and expense posts a journal entry. Real-time profit & loss, invoices and expense tracking — tax-ready.

B2B trade accounts

Trade customers with credit terms. Order → invoice → ledger in three clicks, posting Accounts Receivable and Revenue automatically.

Business email

Every store gets [email protected] or mail on its own domain, with an inbox inside the dashboard plus IMAP/SMTP for phone and desktop mail apps.

Reach more buyers

BizOS Marketplace

List the same catalogue for wholesale and retail with dual pricing. Wholesale buyers send inquiries straight to your dashboard.

TikTok Shop & dropshipping

Push products to TikTok Shop, pull orders back, and auto-forward fulfilment to CJ or AliExpress with tracking synced.

eBay channel

Publish listings with suggested categories, import eBay orders, and push tracking back to the buyer.

Marketing integrations

Google Analytics 4, Meta Pixel, Mailchimp and a WhatsApp chat button — configured per store, no plugins.

AI

AI assistant

Ask “what sold most this week?” or “which products are running low?” and get answers from your live orders, stock and revenue.

Claude / MCP integration

Connect BizOS to Claude through MCP with API keys you manage in settings — Claude can read your orders, products and analytics directly.

Why one system

Sell once. Everything else updates itself.

Sell

Online, in the shop on POS, on TikTok, eBay or the marketplace.

Stock moves

Inventory deducts at the right location, alerts fire before you run out.

Books balance

Revenue, cost of goods and expenses post to the ledger automatically.

You see it

The dashboard and AI assistant reflect it in real time.

BizOS questions

Before you sign up.

Do I need a developer to set up BizOS?

No. Sign up at bizos.uk, name your store, add products and share your link. Your store is live on yourname.bizos.uk straight away; a custom domain can be connected from settings.

Can I use BizOS just for a website, without a shop?

Yes. Website-only mode hides the shop and turns BizOS into a website builder with pages, blocks, a contact form and your own domain.

Can ThinkStacks customise BizOS for my business?

Yes — we build and run BizOS, so we can add integrations, custom pages, data migrations (for example from WooCommerce) or a white-label deployment. Tell us what you need.

Where is my data hosted?

On ThinkStacks-managed servers behind Cloudflare, with each business's data isolated per store.
