Frequently Asked Questions

Does B12 offer a free plan?

Yes. B12's free plan lets you create and publish a website on a B12-branded subdomain with a limited monthly AI credit allowance and access to the core editor — no credit card required and no expiry.

Can I use my own custom domain with B12?

Custom domains are available on paid plans. The Website plan includes a free domain for the first year; the free plan is limited to a b12sites.com subdomain.

What client management tools does B12 include?

On the Website + Client Engagement plan and above, B12 bundles online payments and invoicing, email marketing, a contact manager, contract management, eSignature, and client intake forms — all within the same platform.

Do I need any coding or design skills to use B12?

None at all. You describe your business in plain language and the AI builds the site. Ongoing edits are made through a conversational AI chat or a visual editor designed to feel as simple as a word processor.

Who gets the most value from B12?

B12 is best suited for service-based small businesses — consultants, lawyers, coaches, interior designers, and similar professionals — who want a polished website plus tools for managing clients, contracts, and payments in one place.
