How can I automate invoicing with sevDesk and n8n?

Connect n8n to your project management system and sevDesk via webhooks. When tasks are marked complete, n8n automatically creates invoice line items with the task title, logged time, and client hourly rate. Invoices are generated when accumulated amounts exceed your threshold.

What is the benefit of automated invoicing for freelancers?

The biggest benefit is mental liberation. Automated invoicing eliminates the cognitive burden of remembering which tasks need billing. You can focus on client work and personal time without mentally tracking unbilled items.

How does the 40 euro minimum threshold work in automated invoicing?

Tasks accumulate with a READY FOR PAYMENT status until they cross a minimum threshold (like 40 euros). This avoids creating tiny invoices for short tasks, reducing administrative burden for both you and your clients.

What triggers automatic invoice creation in n8n?

A scheduled trigger runs automatically every three months, checking all clients for tasks with READY FOR PAYMENT status. For clients exceeding the threshold, it creates sevDesk invoices and sends them via email or e-invoicing.

Can sevDesk send invoices automatically via email?

Yes. The sevDesk API supports automatic email sending and e-invoicing (XRechnung/ZUGFeRD). Once configured, invoices are created and sent without manual intervention while you sleep or focus on other work.

How do I connect ClickUp or Airtable to sevDesk for invoicing?

Use n8n as the middleware. Create an Airtable table with client data (hourly rates, sevDesk contact IDs, emails) and a Support Tickets table tracking task titles and time. n8n reads from these tables and creates sevDesk invoices using the sevDesk API.

How much time does automated invoicing save?

Manual invoicing consumes approximately 25 minutes per client when gathering tasks and creating line items. With automation running quarterly at midnight, this time is eliminated entirely, returning 2+ hours monthly to personal time.

What is status-driven automation for invoicing?

Status-driven automation uses task status changes (like marking a task READY FOR PAYMENT) to trigger billing workflows. The automation checks statuses on a schedule, batches qualifying tasks, creates invoices, and updates task statuses to INVOICED automatically.
