As published, Colombia's Dirección de Impuestos y Aduanas Nacionales (DIAN) runs a pre-clearance model: DIAN validates each invoice before it can be issued, not after. The mandate took effect for large taxpayers from January 2019 and, through a phased rollout by business category, became mandatory for all remaining obligated taxpayers by November 2020. The required format is UBL 2.1 XML with a mandatory digital signature, covering B2G, B2B and B2C invoicing (as published — confirm current requirements with your adviser).
LATYNEX Digital builds the workflow around the invoice data your DIAN-authorised e-invoicing provider needs. This page covers it for Medellín businesses. The general service is at Workflow Automation & Systems Integration, and the market overview is at LATYNEX Digital for businesses in Medellín. Delivery is in English, and this page names no client.
Typical industries
- Small and mid-sized retailers and service businesses
- Wholesalers and distributors invoicing B2B and B2C customers
- Manufacturers and exporters billing across sectors
- Finance and back-office teams preparing invoice data
- Businesses issuing high invoice volumes that need pre-clearance built into the process
Common lead-handling problems
- Sales recorded in a spreadsheet or ERP export, then re-keyed for invoicing
- Invoice fields split across several tools with no single UBL 2.1-ready source
- No record of which invoices DIAN's pre-clearance validation rejected, or why
- A missing field found only when an e-invoicing provider rejects a batch before it reaches the buyer
- No internal owner for reconciling issued invoices against DIAN's validated record
Direct answer
If your Medellín business issues invoices that DIAN must validate before they reach the buyer, LATYNEX can build a workflow that turns your existing sales or billing records into one clean invoice data set, checks it against the UBL 2.1 fields your DIAN-authorised provider expects, and gives every rejected or exception invoice an owner before it is resubmitted.
Why the global page and the Medellín hub are not enough
The global Workflow Automation & Systems Integration page has no pre-clearance model to design against, and the Medellín hub is broad discovery for the market. Here the design point is that DIAN validates before issuance, not after, so the invoice data has to be UBL 2.1-ready and digitally signable before submission, not corrected after the buyer has already been billed.
What we configure and build
The work sits before your DIAN-authorised e-invoicing provider, not in place of it.
- An invoice data workflow pulling from your existing sales, billing or ERP records
- Field checks against the UBL 2.1 structure your e-invoicing provider confirms
- A queue for rejected or exception invoices, with an owner and a status
- Separate handling for B2G, B2B and B2C flows where your business issues more than one
- A log of what was prepared, when, and the outcome, plus a written handover
What stays with you and your DIAN-authorised provider
Digital signing, submission for DIAN's pre-clearance validation, and delivery to the buyer stay with your DIAN-authorised e-invoicing provider and your own DIAN registration. Whether a given invoice meets DIAN's current requirements is for you and your adviser; we prepare and check the underlying data, we do not submit it to DIAN.
What needs API support or custom scope
LATYNEX claims no DIAN integration and no invoice-clearance authorisation. Any connection to your DIAN-authorised provider, ERP or accounting system is scoped per project through the documented API or export format if access is permitted, after technical review.
What we do not do, and where LATYNEX is not the right fit
LATYNEX does not give tax or legal advice, does not connect directly to DIAN, does not say an invoice is compliant, and holds no Colombian tax-authority accreditation. It has no Medellín office or named clients, and delivery is in English only. If you already run an ERP with a working DIAN-authorised connector, this page is not for you.
How delivery actually works
LATYNEX Digital has no office in Medellín and does not claim one. We work with Medellín businesses remotely, over video calls and written updates, in English, with the same team and process as in every other market.
Questions
Do you have an office in Medellín?+
No. We work with businesses in Medellín remotely, over video calls and written updates, in English, and we do not imply a local presence.
Do you connect to DIAN or submit invoices for us?+
No. Digital signing, pre-clearance submission and delivery to the buyer stay with your DIAN-authorised e-invoicing provider. We prepare and check the invoice data beforehand.
When did DIAN's e-invoicing mandate become fully mandatory?+
As published, the mandate took effect for large taxpayers from January 2019 and extended, through a phased rollout by business category, to all remaining obligated taxpayers by November 2020. Confirm which category applied to your business with your adviser.
What format does DIAN require?+
As published, DIAN requires UBL 2.1 XML with a mandatory digital signature, and validates each invoice before issuance, covering B2G, B2B and B2C invoicing.
Does this make our invoicing compliant?+
No. We give no tax or legal advice and cannot say your invoicing meets requirements. Confirm current requirements with your adviser; we build to the data set they and your e-invoicing provider specify.
How are you invoiced, and in what currency?+
In EUR, by Latynex Trade OÜ, a company registered in Estonia (EU). Tax treatment for a client in Colombia is confirmed on the quote, and we do not give tax advice.
