# Do you offer post-pay contracts? MessageBird offers a [prepaid account](/connectivity-platform/payment-billing/prepaid-account-billing.md) billing model, so we need a payment to top up your balance before you can send out messages, make voice calls, use numbers, etc. A post-pay contract can be discussed if your minimum spending per month is above 10k. If you wish to discuss a post-pay contract, please reach out to our Sales team via [this page](https://www.messagebird.com/en/contact-sales/). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
