Generate Invoices and Send Reminders for Customers with Jotform and QuickBooks
This workflow automates the entire process of receiving a product/service order, checking or creating a customer in QuickBooks Online (QBO), generating an invoice, emailing it — all triggered by a form submission (via Jotform), and sending invoice reminders.

How It Works
Receive Submission
Triggered when a user submits a form.
Collects data like customer details, selected product/service, etc.

Check If Customer Exists
Searches QBO to determine if the customer already exists.
If Customer Exists:* *Update** customer details (e.g., billing address).
If Customer Doesn’t Exist:* *Create** a new customer in QBO.

Get The Item
Retrieves the selected product or service from QBO.

Create The Invoice
Generates a new invoice for the customer using the item selected.

Send The Invoice
Automatically sends the invoice via email to the customer.

Store The Invoice In DB
Stores the needed invoice details in the DB.

Send Reminders
Every day at 8 AM, the automation checks each invoice to decide whether to:
send a reminder email,
skip and send it later, or
delete the invoice from the DB (if it's paid or all reminders have been sent).
