I will automate quotes, invoices and CRM sync with n8n workflows
Paulius Z.
About this gig
Still copying client data into quotes, invoices and your CRM by hand? I will build an n8n workflow that does it automatically: data comes in, a PDF is generated, the client gets an email and your CRM is updated.
What I can build:
- Quotes and invoices as PDF from your templates
- Web forms, email and webhooks connected to your CRM
- Sync between CRM, accounting, Google Sheets and databases
- Automatic emails, reminders and team notifications
- Error handling and alerts, so nothing fails silently
Why work with me:
- I built and run my own construction cost calculator that uses n8n to generate PDF quotes automatically
- Licensed construction engineer, I understand real business processes, not only nodes
- Clean, documented workflow delivered to your n8n, you keep full ownership
Requirements: you need your own n8n (n8n Cloud or self-hosted). Hosting and installation are not included in the price.
Please message me before ordering with a short description of your process and the apps you use, so I can confirm the scope and the right package.
