What is the downside of B12?

What is the downside of B12? Price, mainly. B12 starts at $49 a month for its Basic plan and climbs to $399 a month for its full done-for-you tiers, per its published pricing as of mid-2026, which puts it among the most expensive small business website options short of hiring an agency. Unite.AI's review says it plainly: more expensive and less flexible than some alternatives. Smaller downsides show up in the sources too. The free plan carries B12 branding and keeps you on a B12 subdomain. ColdIQ's review notes there is no API. And some of what ranks for B12 reviews is old, WebsitePlanet's writeup dates to 2020, so check the date before trusting any verdict.

To be fair about the other side: the things B12 charges for are real. It pairs AI-generated drafts with human design help, GetApp reviewers report an easy setup and intuitive editing, and its Trustpilot page (212 reviews when we pulled the search results) includes returning customers praising the team. Nobody credible calls it a bad product. The recurring complaint is the bill relative to what a small business actually needs.

We compete in the same done-for-you space at $75 a month, so weigh our view, then check the numbers yourself: what B12 costs tier by tier, and our honest B12 review, where we concede what it does well.
