The Shopify page for Intuit says much the same thing and that merchants will be able to sign up for a 30-day free trial. QuickBooks Payments is already available to Shopify and Bigcommerce merchants. QBO integration with both Shopify and Bigcommerce "will be available in the coming months," an Intuit spokesperson said. Both companies said the deal will help more than 150,000 merchants. That must be the estimated size of the market, not the number of customers each has. Shopify's precise description of its services is that it "offers a professional online storefront, a payment solution to accept credit cards, a point of sale system to power retail sales and a card reader to process credit card transactions through a mobile phone."
