Wallet and Billing

Buzzbin uses a prepaid wallet model. Every organization has an IRR wallet balance, and each review run consumes credit based on the actual model cost of that run.

The billing model at a glance​

  • wallet balance is stored in IRR
  • top-ups are recorded directly in IRR
  • each run is first priced in USD
  • when the run executes, that USD cost is converted to IRR and deducted from the wallet

How the FX rate is chosen​

Buzzbin reads the USD-to-IRR rate from market sources and uses a rate that keeps the converted IRR charge from falling below the real external USD compute cost.

That means:

  • a weaker IRR can make the same review cost more in IRR later
  • a previous top-up is not locked to a fixed USD amount

What you see on the Wallet page​

  • Available: spendable credit
  • Balance: total wallet balance
  • Held: credit reserved for in-flight runs
  • Low balance: warning state
  • transaction history and transaction type

Transaction types​

You may see entries such as:

  • TOP_UP
  • FREE_CREDIT
  • RUN_CHARGE
  • REFUND
  • ADMIN_ADJUSTMENT

For run charges, details like costUsd and fxRate are also stored so you can understand why credit was deducted.

What happens when balance is low​

If available balance is not enough, Buzzbin does not start a new run. This keeps usage under control. When you are close to the warning threshold, the Wallet page shows the low-balance state.

Topping up your wallet​

Wallet top-up is self-serve: any organization member can enter an amount on the Wallet page, complete payment through the payment gateway, and have the credit applied to the organization wallet automatically right after a successful payment.

What affects cost​

  • the selected review and answer models
  • how many MRs are reviewed
  • which capabilities are enabled in review config
  • how many follow-up answers or repeated runs happen on a repository
