Generate Invoices for Customers with Jotform, Xero and Slack

This workflow automates the entire process of receiving a product/service order, checking or creating a customer in Xero, generating an invoice, emailing it, and notifying the sales team for example (via Slack) — all triggered by a form submission (via Jotform).

How It Works

  1. Receive Submission
  • Triggered when a user submits a form.
  • Collects data like customer details, selected product/service, etc.
  1. Check If Customer Exists
  • Searches Xero to determine if the customer already exists.
  • If Customer Exists: Update customer details.
  • If Customer Doesn’t Exist: Create a new customer in Xero.
  1. Create The Invoice
  • Generates a new invoice for the customer using the item selected.
  1. Send The Invoice
  • Automatically sends the invoice via email to the customer.
  1. Notify The Team
  • Notifies the sales team for example via Slack about the new invoice.
