B12 is a good AI website builder for professional service firms that also want client intake, scheduling and payments in one place, with real people available to help. As of September 2026 it has a Free plan, Website at $24 a month, and Website + Client Engagement at $78 a month. If you only need a website, that top tier is expensive, and there are cheaper ways to get an AI-built site.

Start free with a template site; AI builds from one prompt on paid plans from $20/mo. On Starter you can compare B12's draft with a We.Inc one-prompt site.

What is B12?

B12 (b12.io) is a website platform built for professional services: accountants, law firms, consultants, coaches, therapists and similar businesses. You give it information about your firm, its AI generates a draft site, and you can edit it yourself or lean on B12's experts. Around the site it adds client-facing tools: online scheduling, intake forms, payments and invoicing, and email marketing.

The pitch is less "build a site in a minute" and more "run the client side of a service firm with a site attached."

The jump from $24 to $78 is where the client tools live. If you already pay for Calendly, a CRM and an invoicing tool, compare that combined cost against $78 before deciding.

How B12 works

  1. Tell B12 about your firm. Services, location, audience.
  2. Get an AI draft. Pages, copy and layout suited to a service business.
  3. Refine. Edit yourself or request changes from B12's team.
  4. Turn on client tools. Booking, intake forms, payments, email campaigns, depending on plan.
  5. Publish on your domain. On a paid plan.

Pros and cons

Pros

  • Built for service firms. Page structures and wording suit accountants, lawyers and consultants.
  • Human help. Experts can make changes, which matters for owners with no time.
  • Client tools in one account. Scheduling, intake, payments and email on the higher plan.
  • Well rated. 4.5 out of 5 on Trustpilot as of September 2026.

Cons

  • $78 a month for the full suite. High if you only want the site.
  • Design flexibility. Layouts are conservative and less customizable than Wix or Framer.
  • No code access. You cannot export the site.
  • Narrow focus. Less suited to shops, restaurants or trades.

B12 vs We.Inc: an honest comparison

  • Free plan. Both have one. We.Inc's lets you build up to 3 sites from templates and publish them free on a we.inc address, no card, but has no AI; building from one prompt and AI editing start on Starter at $20/mo (250 credits). B12's free plan is for drafting; you publish on a paid plan.
  • One-prompt sites. On We.Inc, one sentence, such as "a two-partner accounting firm in Toronto for small businesses, with a free consultation booking form", becomes a full multi-page site you can edit by clicking or in code.
  • White label. Agencies can run We.Inc under their own brand; pricing is quoted on a demo. B12 does not offer this.
  • Where B12 wins. If you want humans to maintain the site and a built-in client intake, scheduling and email stack for a service firm, B12 offers that in one bill. We.Inc does not include email marketing or a done-for-you team.

Starting designs to look at: the Brightside Dental template, the Zenith Realty template and the Velorah Agency template.

What to check before you choose B12

  1. List what you already pay for. Scheduling, invoicing, email marketing and intake forms each have their own subscriptions. If you already pay for three of them, B12's $78 plan might save money. If you pay for none, the $24 Website plan or a cheaper builder may be enough.
  2. Ask about the human help. Find out what kinds of changes B12's team will make, how quickly, and whether there are limits.
  3. Read the cancellation terms. Some critical reviews mention billing questions, so check how and when you can cancel before paying annually.
  4. Review the AI draft closely. Check that services, credentials and compliance wording are accurate for your profession. For regulated fields like law, finance and health, you are responsible for every claim on the site.
  5. Test the client flow. Book a test appointment and pay a test invoice as if you were a client.

Is B12 good for SEO?

B12 sites include the standard settings: titles, descriptions and mobile layouts, and its page structures suit professional services. As with any AI draft, rankings come from specific, trustworthy pages: one per service, clear credentials, named team members and location details. Service firms that add those details usually do better than firms that publish the draft as it is, whichever builder they use.

Verdict

B12 is a thoughtful product for one audience: professional service firms that want a credible site and client tools under one roof, with help on hand. For them, the $78 plan can replace several subscriptions. For everyone else, and for firms that only need the website, $24 a month or less gets you an AI-built site elsewhere.

Start free with a template site; AI builds from one prompt on paid plans from $20/mo. On Starter, describe your firm once and get a full site.
