What differs for CSV upload

For invoices delivered as DOCX, templates are built in Word (2), Google Docs (1) and a fillable PDF form (1). Among them, 1 needs Zapier, Make or n8n to read rows from a CSV file, so it sits after the tools with a direct connection. Of these, 4 have a free tier.

Besides DOCX, these tools for invoices also write PDF (4), XLSX (2) and email (2). Generation runs when a CSV file is uploaded, usually one document per row. Published starting prices run from $19 to $39 a month, the top end from MailMergic. Prices were checked on 20 Oct 2026.
