Electronic invoicing validation

[partomas]

Hello, from 2025 there in Latvia we should use electronic invoicing, but I'm not able to use default functionality. Something went wrong in DEMO environment as well, so could someone explain how to set it accordingly to get working functionality?

Hi,

To be able to generate an E-Invoice it must be valid. It does not pass a rule. Specifically, you didn't configure your country code in settings. You can find more in the docs: Sales Pack > Invoice.

I tried my best to follow documentation https://docs.espocrm.com/user-guide/invoices/ but might be not enought. There are another error appeared: Failed rule ID: PEPPOL-EN16931-R003 (A buyer reference or purchase order reference MUST be provided.)

I didn't find the "purchase order reference" field in CRM and to which field it should be connected if I'll create a custom one?

p.s. "buyer reference" is in the system, but my question is about "purchase order reference" field.

The Buyer Reference field is available in the Invoice entity type. Do you have this field added on the detail layout?

Note that these validation messages are not ours but standard ones. It says about purchase order reference though we don't have this field out of the box (maybe yet).
