This n8n invoice automation template creates a real QuickBooks invoice the moment a job or order is marked complete, emails it to the client and logs it, so invoicing never waits on someone remembering.
One-time purchase. No retainer. Setup guide included.
The workflow file: n8n workflow (JSON)
A step-by-step setup guide (PDF) with a verified cost breakdown
Failure handling: error log with the raw data, a separate Slack failure alert, and a clean response
No credentials included. You connect your own accounts
Make version: coming soon
What this workflow does
A webhook fires from whatever marks a job complete: a project tool automation, an Airtable automation or a simple internal form
A real invoice is created in QuickBooks Online for the client, amount and description
The invoice is emailed to the client from QuickBooks, the same familiar sender your clients already pay through
The invoice is logged to a sheet and your finance channel in Slack is notified
If something fails
If creating the invoice fails, it retries three times automatically
On persistent failure the job details are saved to an Errors sheet, so a completed job never quietly goes unbilled
Your team is alerted in a separate Slack channel

QuickBooks is the dominant cost here, not the automation. If you already pay for QuickBooks, the extra cost of this workflow is just the n8n hosting. QuickBooks pricing has changed more than once this year, so confirm it before you commit.
Who it is for
Useful for agencies, contractors and service businesses that complete jobs throughout the week and want invoices sent promptly and consistently. A Make version is coming soon.
Why a Conviq template
Each template is built to a production standard: failure handling is real, every cost is listed before you buy, and nothing ships with credentials. Browse all n8n workflow templates, learn about our n8n automation services, or have us tailor one as a custom automation project.
Frequently asked questions
Do I need QuickBooks for this template?
This version is built for QuickBooks Online. The setup guide notes how to swap in Xero or FreshBooks.
Does the client need to exist in QuickBooks first?
Yes. The workflow matches the client by email, so each client should already be a customer in QuickBooks.
Is there a Make version?
A Make version is coming soon. The n8n version is available now.
