Below are some conversation starters for a B2B ecommerce functional specification discussion.

B2B organizations & user business logic

• Are there multiple user types? What are they?
• What are each user type permissions (e.g. budget or buying authority)?
• Are there any organizations that users accounts belong to (e.g. school, small business, enterprise)?
• What are the organization types? How do they differ from each other (e.g. manufacturer, retailer, consumer)?
• Are there multiple users per organization or single user only?
• Is the user sign up open to anyone or is it invite based only? Who sends the invites?
• Is there a new user validation / moderation / approval workflow? What are the user account states? Who has permissions to change those states?
• Is there an additional billing contact to share invoices with, but without login permissions?

B2B pricing, purchasing, payments

• Are prices or any other parts of the website hidden from the general public, available only to signed in users? What is your entitlements policy?
• Does the pricing vary between organization or user types?
• What is your discount policy?
• What payment methods are available to which user and organization types?
• Are there any delayed payment “on terms” or “purchase order” transactions allowed for certain organization or user types?
• Would you like to offer quick order or repeat order functionality?
• Would you like to allow orders with split shipments delivered to multiple locations
• Would you like to provide personalized organization or user themes?
