Why it shows up like this
Unreviewed registry note: A billing statement entry labeled CONVEX* BACKEND corresponds to cloud software services from Convex Inc., creators of the Convex Reactive Backend & Database Platform. Engineering teams and software developers use Convex alongside modern web developer tools like Supabase or Clerk Dev to build applications with real-time reactive database syncing and serverless TypeScript functions.
Unreviewed registry note: This charge appears because a team lead or software developer subscribed to the Convex Professional plan. The base tier charges $25 per developer seat each month, renewing automatically. Charges can also rise above the base rate if an application experiences traffic spikes that consume extra database bandwidth or file storage beyond plan allowances.
