DIAN + n8n · Colombia
DIAN electronic invoicing automated with n8n
E-invoicing in Colombia should not be copy-paste XML and forwarding email. We connect your ERP, Siigo or Alegra to the authorized tech provider and n8n: generate, send, log the ack and alert if DIAN rejects. Team in Medellín, same timezone, for SMEs in Antioquia and the rest of the country.
What you get
Fewer typing errors
Data comes from the source system. The flow validates NIT, totals and VAT before issuing.
Traceability
Every invoice has a status: issued, accepted, rejected. Your team sees failures the same day.
Siigo, Alegra or ERP
We do not ask you to switch accounting. We integrate what you already use with the DIAN provider.
Self-hosted
n8n on your server or ours. Your invoices do not travel through Zapier billed per run.
How we work
1. Inventory
We review accounting software, tech provider and monthly invoice volume.
2. Mapping
We define fields, exceptions (credit notes, voids) and who approves before issuing.
3. n8n flow
We build, test with real sandbox invoices, then production.
4. Operations
Alerts, audit log and training for accounting in Medellín or remote.
