Overview
Moloni is an invoicing platform for countries that follow the SAF-T (Standard Audit File for Tax) standard, such as Portugal. The integration sends your Nexudus invoices to Moloni, which formats and registers them so you can submit them to your tax authority or auditors. You keep issuing and managing invoices in Nexudus. The integration is free.Before you start
You need:- A Moloni account on a Flex or Pro plan. Moloni’s Basic plan doesn’t include the API access the integration needs.
- A document set in Moloni for your Nexudus invoices. Every transferred invoice goes into it.
- Matching tax rates. Every tax rate in Nexudus needs an identical rate in Moloni — same name, including capitals, and same percentage. Invoices with an unmatched tax rate are rejected.
Connecting Moloni
- Go to Settings → Integrations → Moloni and select Connect.
- Sign in with your Moloni account and return to Nexudus.
- Choose your Moloni company and the Document Set to transfer documents into, and the other options below.
- Save.

Transferring invoices
Moloni invoices aren’t sent automatically. Go to Finance → Invoices, tick up to 100 invoices, and choose Transfer to Moloni from Bulk actions. Transferred invoices show an In Moloni badge. If you edit an invoice after transferring it, transfer it again — this only works while it isn’t final in Moloni. Credit notes, refunds and payments are sent too. Failed transfers are listed under Finance → Invoices → Moloni errors, with the reason for each.Related
