As a Vendor, you're able to list your business during the signup flow, for other businesses to search and send payments to.
If a vendor has selected this option, you will be able to search for them by name when sending invoices or payments.
If someone has already been added to your network, you can search for them on your Network Page.
At the top of the page to the left, click the search icon and search by the business name or email.
From this view, you can select the vendor you're searching for, add them as a favorite, edit the contact, remove them from your network, send them a payment, request a payment, or send them a reminder. You're also able to view all transaction history with the vendor.
Another way you can search your network for vendors is to simply click "Send Payment" or "Request Payment" and search their business name or email and select the vendor you're looking to pay/invoice.
