# Marketplace Payment services through Paywall can also be used for marketplace flows. The marketplace model is a system where you manage your subsidiary companies through a single channel and Paywall calculates and distributes your earnings based on the information you provide. You can transform all your payment flows into a marketplace model by filling in the MemberId parameter within the payment parameters of the Product parameter. The process is not difficult :tada: As mentioned, you simply specify in the payment requests which sub-member business your products belong to. So, what information will fill the MemberId? That's a very good question. You will define your subsidiary businesses in Paywall using the services under the Member Service. With this definition, MemberId will now be generated, and you can use it for your payments. The commission/fee management that you will apply to all subsidiary businesses is left to your discretion. --- # 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.
