FAQ: Medius vs. OpenText VIM
Both solutions support global entities with multiple invoice formats and currencies. Medius offers broader ERP flexibility, making it stronger for companies expanding through acquisitions where multi‑ERP environments are common. As a true cloud solution Medius is also more scalable. In addition, Medius offers e‑invoice compliance, live language translation and advanced PO matching capabilities to support growing invoice volumes and international expansions.
Medius provides proactive AI-driven fraud detection with invoice risk scoring and configurable controls. OpenText’s fraud prevention uses rule-based validation and checks to flag duplicates, mismatches and unusual activity.
On average, Medius can be implemented in a few weeks to a few months, depending on factors like number of entities, ERP environment, and PO-matching complexity.
Yes, but matching is only done at header level, which leads to more manual exception handling.
The main difference lies in the ability to enable fully touchless data capture. Medius’ native AI-driven capture solution analyzes workflow data to achieve high automation from the first invoice – up to 99% touchless capture over time. OpenText’s add-on module for data capture relies on templates and pre-defined configurations, requiring more manual corrections.
