This article covers the new Supply experience, which is only available to organizations in Australia. If your organization is outside Australia, you're on the legacy version for now.
What are the differences between payment methods in Supply?
Mitti Supply has three types of payment methods: organization, buying group, and personal. Each type differs in who can add it and who can use it.
Organization: An organization payment method is for the entire organization and can be shared with buying groups, so several groups can pay with the same payment method. Only Supply admins can add an organization payment method.
Buying group: A buying group payment method belongs to one buying group, and its members can use it at checkout. You can also share a buying group payment method with other buying groups, and their members can then use it too. Supply admins and users assigned as group managers can add a buying group payment method.
Personal: A personal payment method is for your own use. Only the person who added it can use it to pay for their own orders.
At checkout, you can select your personal payment method or a payment method available to a buying group you belong to. Adding the right type means each payment method is available only to the people who should use it at checkout.
