I am new in Shopify, I have several questions below:
1) Shopify gets SSO plugin with a price, is it USD 149/month for 4K unique users/month?
2) Shopify pricing is monthly or annually? and with additional surcharge per transaction?
3) Shopify allows development, but only via certified partners, may I know how to join?
1. Are you looking to offer SSO to your customers or something else? Where are you getting the pricing?
2. Shopify charges both monthly and annually. Annual payments are non-refundable but will save you 10% on your plan. You can view our plans and their fees here.
3. Shopify Partners is free to any developer who wishes to refer clients to Shopify. You can find more information on Shopify Partners here.
