i.VAZ & i.SAF automation: ERP straight into VMI i.MAS
Automated i.VAZ and i.SAF submission removes the manual XML and re-keying work that creates filing errors. We bridge your existing ERP (Rivilė, Directo, or B1.lt) directly to VMI's i.MAS APIs, with full audit logging and human review for exceptions. Related: logistics automation.
Waybills and VAT registers leave your ERP, transform into the VMI-required format, and are submitted automatically. Your accountant reviews edge cases instead of typing the same fields by hand every week.
Manual VMI filing is slow and error-prone
Each i.VAZ waybill takes 3–5 minutes of manual data entry. Across 50 shipments a day, that is around 4 hours of accountant or logistics time spent re-keying data that already exists in the ERP. Small typos in the XML can trigger VMI rejections and stop trucks at the border.
A rejected i.VAZ can delay dispatch and lead to administrative penalties under VMI rules.

How it works
Source the data
An n8n or Make workflow listens to your ERP (Rivilė, Directo, B1.lt) for a new invoice or waybill via REST API or webhook.
Build the payload
The workflow maps your ERP fields to the VMI XML schema. Validation rules catch missing or malformed fields before submission.
Submit and log
The payload is submitted to VMI i.MAS. The response (confirmation or error) is logged and any failures are routed to your accountant for review.
i.VAZ waybill submission
Trigger from your TMS or ERP when a shipment is dispatched. The waybill is submitted to VMI within seconds, and the driver's QR documentation is ready before they leave the loading bay.

i.SAF VAT register generation
Pull invoice data from Rivilė at the end of each reporting period, generate the i.SAF XML, validate, and submit. No more manual exports and reformatting in Excel.
