The short answer
A charge from CONVEX* BACKEND corresponds to reactive backend-as-a-service database hosting, serverless functions, or vector search subscriptions from Convex Inc.
Why it shows up like this
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.
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.
To review what triggered the debit, sign into dashboard.convex.dev and navigate to Team Settings Billing. Workspace administrators can inspect monthly invoices and downgrade an unneeded project to the Free Starter plan. If no developer on your team authorized this expense and your card was compromised, contact your bank immediately to file a fraud dispute. Keeping close track of your monthly statements ensures complete financial security and prevents unexpected surprises from recurring charges.
