Addresses are needed when creating new invoices to your clients. It is necessary to engage your clients to setup their default addresses from top right corner under My profile link.
Your company’s clients from China, Japan and Russia need to include Street 2 address when setting up their default address. It is important when making payments through 2Checkout gateway, otherwise an error will be thrown.
By default, when a client selects any of the three countries, a street 2 textbox is loaded automatically.
