QuickBooks Online can be used to automate invoicing processes for businesses that sell through eCommerce platforms like Shopify or Stripe, but manual creation of invoices can be time-consuming and prone to errors. To streamline this process, businesses can set up Zaps using Zapier, which connect QuickBooks Online with their sales platform of choice. The Zapping process involves connecting the app that generates orders, customizing triggers and actions, and configuring fields to create accurate invoices. With a few steps, businesses can set up an automated workflow that turns new orders into invoices in QuickBooks Online, eliminating manual work and potential errors.
